Review
BACKGROUND
Chronic deep venous insufficiency is caused by incompetent vein valves, blockage of large-calibre leg veins, or both; and causes a range of symptoms including recurrent ulcers, pain and swelling. Most surgeons accept that well-fitted graduated compression stockings (GCS) and local care of wounds serve as adequate treatment for most people, but sometimes symptoms are not controlled and ulcers recur frequently, or they do not heal despite compliance with conservative measures. In these situations, in the presence of severe venous dysfunction, surgery has been advocated by some vascular surgeons. This is an update of the review first published in 2000.
OBJECTIVES
To assess the effects of surgical management of deep venous insufficiency on ulcer healing and recurrence, complications of surgery, clinical outcomes, quality of life (QoL) and pain.
SEARCH METHODS
The Cochrane Vascular Information Specialist searched the Cochrane Vascular Specialised Register, CENTRAL, MEDLINE, Embase and CINAHL databases, and the WHO ICTRP and ClinicalTrials.gov trials registries to 23 June 2020.
SELECTION CRITERIA
We considered randomised controlled trials (RCTs) of surgical treatment versus another surgical procedure, usual care or no treatment, for people with deep venous insufficiency.
DATA COLLECTION AND ANALYSIS
Two review authors independently assessed trials for inclusion, extracted data and assessed the risk of bias with the Cochrane risk of bias tool. We evaluated the certainty of the evidence using GRADE. We were unable to pool data due to differences in outcomes reported and how these were measured. Outcomes of interest were ulcer healing and recurrence, complications of surgery, clinical changes, QoL and pain.
MAIN RESULTS
We included four RCTs (273 participants) comparing valvuloplasty plus surgery of the superficial venous system with surgery of the superficial venous system for primary valvular incompetence. Follow-up was two to 10 years. All included studies investigated primary valve incompetence. No studies investigated other surgical procedures for the treatment of people with deep venous insufficiency or surgery for secondary valvular incompetence or venous obstruction. The certainty of the evidence was downgraded for risk of bias concerns and imprecision due to small numbers of included trials, participants and events. None of the studies reported ulcer healing or ulcer recurrence. One study included 27 participants with active venous ulceration at the time of surgery; the other three studies did not include people with ulcers. There were no major complications of surgery, no incidence of deep vein thrombosis and no deaths reported (very low-certainty evidence). All four studies reported clinical changes but the data could not be pooled due to different outcome measures and reporting of the data. Two studies assessed clinical changes using subjective and objective measurements, as specified in the clinical, aetiological, anatomical and pathophysiological (CEAP) classification score (low-certainty evidence). One study reported mean CEAP severity scores and one study reported change in clinical class using CEAP. At baseline, the mean CEAP severity score was 18.1 (standard deviation (SD) 4.4) for limbs undergoing external valvuloplasty with surgery to the superficial venous system and 17.8 (SD 3.4) for limbs undergoing surgery to the superficial venous system only. At three years post-surgery, the mean CEAP severity score was 5.2 (SD 1.6) for limbs that had undergone external valvuloplasty with surgery to the superficial venous system and 9.2 (SD 2.6) for limbs that had undergone surgery to the superficial venous system only (low-certainty evidence). In another study, participants with progressive clinical dynamics over the five years preceding surgery had higher rates of improvement in clinical condition in the treatment group (valvuloplasty plus ligation) compared with the control group (ligation only) (80% versus 51%) after seven years of follow-up. Participants with stable preoperative clinical dynamics demonstrated similar rates of improvement in both groups (95% with valvuloplasty plus ligation versus 90% with ligation only) (low-certainty evidence). One study reported disease-specific QoL using cumulative scores from a 10-item visual analogue scale (VAS) and reported that in the limited anterior plication (LAP) plus superficial venous surgery group the score decreased from 49 to 11 at 10 years, compared to a decrease from 48 to 36 in participants treated with superficial venous surgery only (very low-certainty evidence). Two studies reported pain. Within the QoL VAS scale, one item was 'pain/discomfort' and scores decreased from 4 to 1 at 10 years for participants in the LAP plus superficial venous surgery group and increased from 2 to 3 at 10 years in participants treated with superficial venous surgery only. A second study reported that 'leg heaviness and pain' was resolved completely in 36/40 limbs treated with femoral vein external valvuloplasty plus high ligation and stripping of the great saphenous vein (GSV) and percutaneous continuous circumsuture and 22/40 limbs treated with high ligation and stripping of GSV and percutaneous continuous circumsuture alone, at three years' follow-up (very low-certainty evidence).
AUTHORS' CONCLUSIONS
We only identified evidence from four RCTs for valvuloplasty plus surgery of the superficial venous system for primary valvular incompetence. We found no studies investigating other surgical procedures for the treatment of people with deep venous insufficiency, or that included participants with secondary valvular incompetence or venous obstruction. None of the studies reported ulcer healing or recurrence, and few studies reported complications of surgery, clinical outcomes, QoL and pain (very low- to low-certainty evidence). Conclusions on the effectiveness of valvuloplasty for deep venous insufficiency cannot be made.

BACKGROUND
Recanalization in cerebral venous thrombosis (CVT) can begin as early as 1 week after initiating therapeutic anticoagulation. The clinical significance of recanalization remains uncertain.
OBJECTIVES
We aimed to investigate the association between recanalization and functional outcomes and explored predictors of recanalization.
METHODS
A systematic literature search was conducted (EMBASE, MEDLINE, Cochrane library) to identify: (1) patients with CVT aged ≥18 years treated with anticoagulation only; (2) case series, cohort, or randomized controlled trial studies; and (3) reported recanalization rates and functional outcomes using either a modified Rankin Scale (mRS) or sequelae of CVT at last follow-up. Meta-analysis was performed using pooled odds ratios (ORs) with exploration of sex and age effects using meta-regression.
RESULTS
Twenty-three studies were eligible with 1418 individual patients in total. Timing of reimaging and clinical reassessment was variable. Absence of recanalization was associated with increased odds of an unfavorable functional outcome (mRS 2-6 versus 0-1; OR, 3.66; 95% CI, 1.73-7.74; = 0.001), CVT recurrence (OR, 8.81; 95% CI, 1.63-47.7; = 0.01), and chronic headache (OR, 2.78; 95% CI, 1.16-6.70; = 0.02). On meta-regression, the relationship between recanalization and mRS differed by the proportion of female patients, where lower proportions of women were associated with higher likelihood of a worse outcome, but not by mean participant age. There was no incremental benefit of full compared with partial recanalization with respect to favorable mRS or recurrence, but odds of chronic headache were higher with partial versus full recanalization (OR, 3.80; 95% CI, 1.43-10.11; = 0.008). Epilepsy and visual sequelae were not associated with recanalization.
CONCLUSIONS
Absence of recanalization was associated with worse functional outcomes, CVT recurrence, and headache, but outcomes were modified by sex. The degree of recanalization was significant in relation to headache outcomes, where partial compared with complete recanalization resulted in a greater likelihood of residual headache. Prospective studies with common timing of repeat clinical-neuroimaging assessments will help to better ascertain the relationship and directionality between the degree of recanalization and outcomes.

Meta-Analysis
The novel coronavirus disease 2019 (COVID-19) predisposes patients to venous thromboembolism (VTE) due to risk factors, severe infection, and severe inflammatory responses. The objective is to determine the risk of developing VTE after corticosteroid administration during COVID-19 treatment. Using PRISMA reporting guidelines, a review was conducted from inception until 20 September 2020 with MESH terms including "venous thromboembolism" and "covid-19," using MEDLINE, Scopus, CINAHL Plus, and WHO Global Database. The inclusion criteria included studies with COVID-19 patients aged 18 years and older with VTE diagnosed by duplex ultrasonography or computed tomography pulmonary angiography (CTPA). Exclusion criteria were studies with non COVID-19 patients and non-VTE patients aged less than 18 years. Quality appraisal was conducted of included studies using the Newcastle-Ottawa Scale (NOS). A random-effect model using 95% confidence intervals, and significance of findings was assessed using Review Manager V5.4.We included 12 observational studies with 2801 patients (VTE n = 434; non-VTE; n = 2367). Patients had a higher risk of presenting with VTE when being administered corticosteroids during treatment of COVID-19 (RR = 1.39, 95% CI = 1.10 to 1.77, I = 0%). A positive effect size was found (SMD = 1.00, 95% CI = 0.67 to 1.32, I = 85%) for D-dimer laboratory values (µg/mL) in the VTE group. While critically ill COVID-19 patients are more likely to require corticosteroid treatment, it may be associated with increased risk of VTE, and poor clinical prognosis. Risk assessment is warranted to further evaluate patients as case-by-case in reducing VTE and worsening clinical outcomes.

Review
BACKGROUND
Deep venous thrombosis (DVT) occurs in approximately one in 1000 adults every year, and has an annual mortality of 14.6%. In particular, iliofemoral DVT can lead to recurrent thrombosis and post-thrombotic syndrome (PTS), a painful condition which can lead to chronic venous insufficiency, oedema, and ulceration. It causes significant disability, impaired quality of life, and economic burden. Early thrombus removal techniques have been advocated in patients with an iliofemoral DVT in order to improve vein patency, prevent valvular dysfunction, and reduce future complications, such as post-thrombotic syndrome and venous ulceration. One such technique is pharmacomechanical thrombectomy, a combination of catheter-based thrombectomy and catheter-directed thrombolysis.
OBJECTIVES
To assess the effects of pharmacomechanical thrombectomy versus anticoagulation (alone or with compression stockings), mechanical thrombectomy, thrombolysis, or other endovascular techniques in the management of people with acute DVT of the iliofemoral vein.
SEARCH METHODS
The Cochrane Vascular Information Specialist searched the Specialised Register (last searched December 2015) and the Cochrane Register of Studies (last searched December 2015). We searched clinical trials databases for details of ongoing or unpublished studies and the reference lists of relevant articles retrieved by electronic searches for additional citations.
SELECTION CRITERIA
Randomised controlled trials in which patients with an iliofemoral deep vein thrombosis were allocated to receive pharmacomechanical thrombectomy versus anticoagulation, mechanical thrombectomy, thrombolysis (systemic or catheter directed thrombolysis), or other endovascular techniques for the treatment of iliofemoral DVT.
DATA COLLECTION AND ANALYSIS
At least two review authors independently assessed studies identified for potential inclusion.
MAIN RESULTS
We found no randomised controlled trials that met the eligibility criteria for this review. We identified one ongoing study.
AUTHORS' CONCLUSIONS
There were no randomised controlled trials that assessed the effects of pharmacomechanical thrombectomy versus anticoagulation (alone or with compression stockings), mechanical thrombectomy, thrombolysis, or other endovascular techniques in the management of people with acute DVT of the iliofemoral vein that met the eligibility criteria for this review. Further high quality randomised controlled trials are needed.

Meta-Analysis Review
BACKGROUND
Identifying late epileptic seizures (LS) following cerebral venous thrombosis (CVT) can be useful for prognosis and management. We systematically reviewed the literature to identify risk factors for LS due to CVT.
METHODS
We systematically searched PubMed, Scholar, and Scopus databases (May 2021) to identify studies reporting data on prevalence and risk factors for CVT-LS. The methodological quality was assessed with the Ottawa-Newcastle Scale. The risk of developing CVT-LS was summarized in meta-analyses and expressed as odds ratio (OR) and corresponding 95% confidence intervals (CIs) using random-effects models.
RESULTS
Out of the 332 records retrieved, four studies were eventually included with a total of 1309 patients with CVT and 142 (11%) with CVT-LS. The most relevant predictors of CVT-LS were symptomatic seizures (OR 5.66, 95% CI 3.83-8.35), stupor/coma (OR 6.81, 95% CI 1.18-39.20), focal neurologic signs (OR 6.81, 95% CI 1.18-39.2), hemorrhagic component (OR 3.52, 95% CI 2.45-5.06), and superior sagittal sinus involvement (OR 1.52, 95% CI 1.04-2.21).
CONCLUSION
There are several risk factors for CVT-LS that should be considered in clinical practice. Further high-quality studies are warranted to develop predictive models for individualized risk stratification and prediction of CVT-LS.

Meta-Analysis Review
BACKGROUND AND PURPOSE
Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection predisposes patients to arterial and venous thrombosis. This study aimed to systematically review the available evidence in the literature for cerebral venous thrombosis (CVT) in association with coronavirus disease-2019 (COVID-19).
METHODS
We searched MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases to identify cases of COVID-19-associated CVT. The search period spanned 1 January 2020 to 1 December 2020, and the review protocol (PROSPERO-CRD42020214327) followed Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Identified studies were evaluated for bias using the Newcastle-Ottawa scale. A proportion meta-analysis was performed to estimate the frequency of CVT among hospitalized COVID-19 patients.
RESULTS
We identified 57 cases from 28 reports. Study quality was mostly classified as low. CVT symptoms developed after respiratory disease in 90%, and the mean interval was 13 days. CVT involved multiple sites in 67% of individuals, the deep venous system was affected in 37%, and parenchymal hemorrhage was found in 42%. Predisposing factors for CVT beyond SARS-CoV-2 infection were present in 31%. In-hospital mortality was 40%. Using data from 34,331 patients, the estimated frequency of CVT among patients hospitalized for SARS-CoV-2 infection was 0.08% (95% confidence interval [CI]: 0.01-0.5). In an inpatient setting, CVT accounted for 4.2% of cerebrovascular disorders in individuals with COVID-19 (cohort of 406 patients, 95% CI: 1.47-11.39).
CONCLUSIONS
Cerebral venous thrombosis in the context of SARS-CoV-2 infection is a rare, although there seems to be an increased relative risk. High suspicion is necessary, because the diagnosis of this potentially life-threatening condition in COVID-19 patients can be challenging. Evidence is still scarce on the pathophysiology and potential prevention of COVID-19-associated CVT.

Review
Extraintestinal manifestations of celiac disease (CD) should be considered, even in patients without typical intestinal symptoms. The aim of our study is to examine the literature regarding the occurrence of thrombotic events in CD, and to synthesize the data from case reports and case series. A systematic review of the literature was conducted by searching the Pub-Med/MEDLINE database, from the date of database inception to January 2022, to identify published cases and case series on this topic, in accordance with the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. A total of 55 cases were included in the study. The majority of patients were previously healthy individuals, with no comorbidities. In less than one-third of the cases (30.91%), the diagnosis of CD was established before the onset of thrombosis, while in the remaining cases (34.54%), thrombosis preceded the diagnosis or was diagnosed concomitantly with CD. The most common sites for thrombosis occurrence were hepatic veins (30.91%), while thrombosis of cerebral blood vessels, deep venous thrombosis of lower extremities, and pulmonary thromboembolism were less frequent. Thrombosis was most commonly isolated to one site only (78.18%). In 69.09% of cases ( = 38), some form of anticoagulation, along with a gluten-free diet, was initiated.

Review
A Systematic Review and Bayesian Network Meta-Analysis on the Effect of Different Anticoagulants on the Prophylaxis of Post-Thrombotic Syndrome after Deep Venous Thrombosis.
BACKGROUND
Postthrombotic syndrome (PTS) has a major impact on the quality of life after deep venous thrombosis (DVT). From clinical practice and related trials, anticoagulants show potential for reducing the occurrence and alleviating the symptoms of PTS.
METHODS
A systematic review and Bayesian network meta-analysis (NMA) were conducted by combing the literature from the databases of MEDLINE, Embase, Web of Science, Cochrane Libraries, and ClinicalTrials, through a variety of medical subject headings (Mesh) and PTS keywords. With regard to PTS prophylaxis, all anticoagulant-related randomized controlled trials (RCTs) and observational studies were assessed. The network model was conducted through the R software, and further comparisons were conducted using the Bayesian hierarchical random effects model. The odds ratio (OR) and the corresponding 95% CI were calculated for analysis.
RESULTS
Data from two RCTs and nine non-randomized studies meeting the selection criteria were included in the Bayesian analysis model, which incorporated seven anticoagulants. Edoxaban (OR: 0.42, 95% CI: 0.18-1.0) and rivaroxaban (OR: 0.54, 95% CI: 0.38-0.76) were significantly more effective than warfarin in the prevention of PTS (Villalta score ≥ 5). A subgroup analysis based on the severity of PTS showed that rivaroxaban was more effective than warfarin, with OR: 0.59, 95% CI: 0.41-0.84 (Villalta score 5 to 14) and OR: 0.48, 95% CI: 0.22-0.9 (Villalta score ≥ 15, ulceration), respectively. Edoxaban had the highest probability (80.1%) of providing preventive benefits for PTS. For mild/moderate and severe PTS, rivaroxaban provided the highest benefits in preventing PTS (89.3% and 85.6%, respectively).
CONCLUSION
Edoxaban demonstrated a better prophylactic effect on PTS (Villalta score > 5), while rivaroxaban displayed a better effect against mild/moderate (Villalta score 5 to 14) and severe PTS (Villalta score ≥ 15, ulceration).

Meta-Analysis Review
BACKGROUND
Ischaemic stroke interrupts the flow of blood to part of the brain. Haemodilution is thought to improve the flow of blood to the affected areas of the brain and thus reduce infarct size.
OBJECTIVES
To assess the effects of haemodilution in acute ischaemic stroke.
SEARCH METHODS
We searched the Cochrane Stroke Group Trials Register (February 2014), the Cochrane Central Register of Controlled Trials (Issue 1, 2014), MEDLINE (January 2008 to October 2013) and EMBASE (January 2008 to October 2013). We also searched trials registers, scanned reference lists and contacted authors. For the previous version of the review, the authors contacted manufacturers and investigators in the field.
SELECTION CRITERIA
Randomised trials of haemodilution treatment in people with acute ischaemic stroke. We included only trials in which treatment was started within 72 hours of stroke onset.
DATA COLLECTION AND ANALYSIS
Two review authors assessed trial quality and one review author extracted the data.
MAIN RESULTS
We included 21 trials involving 4174 participants. Nine trials used a combination of venesection and plasma volume expander. Twelve trials used plasma volume expander alone. The plasma volume expander was plasma alone in one trial, dextran 40 in 12 trials, hydroxyethyl starch (HES) in five trials and albumin in three trials. Two trials tested haemodilution in combination with another therapy. Evaluation was blinded in 14 trials. Five trials probably included some participants with intracerebral haemorrhage. Haemodilution did not significantly reduce deaths within the first four weeks (risk ratio (RR) 1.10; 95% confidence interval (CI) 0.90 to 1.34). Similarly, haemodilution did not influence deaths within three to six months (RR 1.05; 95% CI 0.93 to 1.20), or death and dependency or institutionalisation (RR 0.96; 95% CI 0.85 to 1.07). The results were similar in confounded and unconfounded trials, and in trials of isovolaemic and hypervolaemic haemodilution. No statistically significant benefits were documented for any particular type of haemodiluting agents, but the statistical power to detect effects of HES was weak. Six trials reported venous thromboembolic events. There was a tendency towards reduction in deep venous thrombosis or pulmonary embolism or both at three to six months' follow-up (RR 0.68; 95% CI 0.37 to 1.24). There was no statistically significant increased risk of serious cardiac events among haemodiluted participants.
AUTHORS' CONCLUSIONS
The overall results of this review showed no clear evidence of benefit of haemodilution therapy for acute ischaemic stroke.These results are compatible with no persuasive beneficial evidence of haemodilution therapy for acute ischaemic stroke. This therapy has not been proven to improve survival or functional outcome.

Meta-Analysis
Data regarding the occurrence of venous thromboembolic events (VTE), including acute pulmonary embolism (PE) and deep vein thrombosis (DVT) in recovered COVID-19 patients are scant. We performed a systematic review and meta-analysis to assess the risk of acute PE and DVT in COVID-19 recovered subject. Following the PRIMSA guidelines, we searched Medline and Scopus to locate all articles published up to September 1st, 2022, reporting the risk of acute PE and/or DVT in patients recovered from COVID-19 infection compared to non-infected patients who developed VTE over the same follow-up period. PE and DVT risk were evaluated using the Mantel-Haenszel random effects models with Hazard ratio (HR) as the effect measure with 95% confidence interval (CI) while heterogeneity was assessed using Higgins I statistic. Overall, 29.078.950 patients (mean age 50.2 years, 63.9% males), of which 2.060.496 had COVID-19 infection, were included. Over a mean follow-up of 8.5 months, the cumulative incidence of PE and DVT in COVID-19 recovered patients were 1.2% (95% CI:0.9-1.4, I2: 99.8%) and 2.3% (95% CI:1.7-3.0, I2: 99.7%), respectively. Recovered COVID-19 patients presented a higher risk of incident PE (HR: 3.16, 95% CI: 2.63-3.79, I = 90.1%) and DVT (HR: 2.55, 95% CI: 2.09-3.11, I: 92.6%) compared to non-infected patients from the general population over the same follow-up period. Meta-regression showed a higher risk of PE and DVT with age and with female gender, and lower risk with longer follow-up. Recovered COVID-19 patients have a higher risk of VTE events, which increase with aging and among females.
