BACKGROUND
Arteriovenous fistula pseudoaneurysm (AVF-PSA) is a common complication, usually caused during dialysis cannulation, which traditionally has been treated with open and less frequently endovascular techniques. Thrombin injection, although established in the treatment of arterial pseudoaneurysms, has barely been used in the treatment of AVF-PSA, due to concerns for AVF thrombosis or proximal embolization.
METHODS
A systematic review was performed according to the PRISMA 2020 guidelines. PubMed and Cochrane Central databases were reviewed and all clinical reports on AVF-PSA balloon assisted percutaneous thrombin injection through July 2022 were included. The electronic search yielded five case reports. Due to between-study differences and small sample size, the findings were summarized from each report, but the results were not pooled. Additionally, we present our own experience on two patients with AVF-PSA that were treated with balloon assisted percutaneous thrombin injection.
RESULTS
A total of five case reports (no of patients: 7, including ours) were included for review. Most of the patients were male ( = 6) and the mean age was 65.9 years. The average size of the PSA was 1.6 cm. In all cases a balloon was inflated to prevent thrombin and thrombotic material intrusion into the fistula lumen, prior to thrombin injection. In one patient n-butyl cyanoacrylate and Lipiodol were used, due to thrombin non availability. Recurrence was reported in only one patient, and average follow-up is 16 months.
CONCLUSIONS
Thrombin injection with concomitant balloon inflation seems to be a safe and effective treatment for arteriovenous fistula pseudoaneurysms. Future studies should be aimed at evaluating the long-term outcomes of such minimally invasive techniques.

Solving Intraoperative Complications During Endovascular Repair of Late Contained Ruptured Aortic Pseudoaneurysm After Surgical De-coarctation: Case Report and Systematic Review of Literature.
AIM
We present a case of successful endovascular repair of late ruptured aortic anastomotic pseudoaneurysm following previous left subclavian artery-descending thoracic aorta bypass and concomitant emergency thoracic endovascular aortic repair (TEVAR) of complicated endovascular aortic de-coarctation never previously described is also presented. A review of the intraoperative, 30-day, and follow-up morbidity, mortality, and complications of TEVAR as endovascular treatment of late aneurysm/pseudoaneurysms after surgical aortic de-coarctation was also performed.
METHODS
The systematic review was performed in accordance with the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) statement and following PICO model. A literature search was conducted on MEDLINE, PubMed, EMBASE, Cochrane Library, Google Scholar, Science Direct, and Web of Science using the words "tevar of late complication of aortic coarctation surgical repair" and "endovascular repair of anastomotic pseudoaneurysm in coarctation" up to June 17, 2022. Data were extracted from study documents about study design, patient's demographics and comorbidities, details about primary surgical repair, type of late complication, time between open surgery and occurrence of complications, details of the secondary endovascular procedure with technical success, early, and follow-up mortality and morbidity.
RESULTS
A total of 18 papers were included with 78 patients (48 men, 69.5%). The most frequent type of primary open surgical repair was patch aortoplasty (46, 58.9%). Focusing on aneurysm and pseudoaneurysm as late complications, most of the patients were asymptomatic (45, 57.7%). All patients underwent TEVAR, 14 of them (17.9%) in urgent/emergent setting. The technical success was 98.7%, with 1 intraoperative death due to rupture of the aorta. In total, 31 patients out of 78 (39.7%) showed different complications in the immediate postoperative time, with type II endoleak being the most observed (8/31, 25.8%). The mean follow-up time was about 2 years (26.5 months, range 3-92). Overall, 30-day mortality was 2.6%. Complications occurred in 30 patients (39.4%), 23 of them resolved during the follow-up period.
CONCLUSIONS
With the limit of low-quality data, TEVAR can be considered a safe and effective option for the treatment of late complications after open surgery for aortic coarctation, even in urgent settings.
CLINICAL IMPACT
Different specialists have to face the technical complexities and risks related to treatment of late complications after surgical de-coartaction, which can be either surgical or endovascular, and depend on patient's ages. Although covered stents appear to have some protection from the development of stent fractures, doesn't provide complete protection from late aneurysm formation. In this setting, TEVAR may represent a valuable option, combining the advantages of the covered stent with those of a device that can cover a wider range of aortic length, especially in adult patients. This study shows thoracic endovascular repair can be considered a safe and effective option in clincal practice for the treatment of late complications after open surgery for AC, even in urgent settings.

Meta-Analysis
OBJECTIVE
Pseudoaneurysms (PSAs) are complex vascular lesions. Flow diversion has been proposed as an alternative treatment to parent artery occlusion that preserves laminar flow. The authors of the present study investigated the safety and short-term (< 1 year) and long-term (≥ 1 year) aneurysm occlusion rates following the treatment of intracranial and extracranial PSAs using the Pipeline embolization device (PED).
METHODS
An electronic database search for full-text English-language articles in Ovid MEDLINE and Epub Ahead of Print, Ovid Embase, Ovid Cochrane Central Register of Controlled Trials, Ovid Cochrane Database of Systematic Reviews, and Scopus was conducted following the PRISMA guidelines. Studies of any design including at least 4 patients with intracranial or extracranial PSAs treated using a PED were included in this analysis. The primary outcome of interest was the rate of peri- and postprocedural complications. Secondarily, the authors analyzed the incidence of complete aneurysm occlusion.
RESULTS
A total of 90 patients with 96 PSAs across 9 studies were included. The mean age was 38.2 (SD 15.14) years, and 37.8% of the patients were women. The mean PSA size was 4.9 mm. Most PSAs were unruptured, and the most common etiology was trauma (n = 32, 35.5%), followed by spontaneous formation (n = 21, 23.3%) and iatrogenic injury (n = 19, 21.1%). Among the 51 (53.1%) intracranial and 45 (46.9%) extracranial PSAs were 19 (19.8%) dissecting PSAs. Sixty-six (77.6%) PSAs were in the internal carotid artery and 10 (11.8%) in the vertebral artery. Thirty-three (34.4%) PSAs were treated with ≥ 2 devices, and 8 (8.3%) underwent adjunctive coiling. The mean clinical and angiographic follow-up durations were 10.7 and 12.9 months, respectively. The short-term (< 1 year) and long-term (≥ 1 year) complete occlusion rates were 79% (95% CI 66%-88%, p = 0.82) and 84% (95% CI 70%-92%, p = 0.95), respectively. Complication rates were 8% for iatrogenic dissection (95% CI 3%-16%, p = 0.94), 10% for silent thromboembolism (95% CI 5%-21%, p = 0.77), and 12% for symptomatic thromboembolism (95% CI 6%-23%, p = 0.48). No treatment-related hemorrhage was observed. The overall mortality rate at the last follow-up was 14%.
CONCLUSIONS
The complete occlusion rate for PSAs treated with the PED was high and increased over time. Although postprocedural complications and mortality were not insignificant, flow diversion represents a reasonably safe option for managing these complex lesions.

INTRODUCTION
Total knee arthroplasty (TKA) is a common operation and is becoming more common due to population aging and increasing BMI. TKA provides excellent improvement in quality of life but carries risk of arterial complications in the perioperative period. This systematic review aims to provide a greater understanding of the incidence of such complications, and time taken to diagnose arterial injury.
MATERIALS AND METHODS
PubMed, Medline, Ovid SP and EMBASE databases were searched with the following MeSH keywords: 'complication', 'vascular injury', 'ischaemia', 'spasm', 'thrombosis', 'pseudoaneurysm', 'transection', 'pulse', 'ABPI OR ABI', 'Doppler', 'amputation'. All arterial vascular events in the perioperative state of the total knee replacement were included. Records were independently screened by two reviewers, and data was extracted according to a pre-determined proforma. Overall incidence and time to diagnosis was calculated for complications. Systematic review registration PROSPERO: CRD42018086643. No funding was received.
RESULTS
Twelve studies were selected for inclusion. A total of 3325 cases of arterial complications were recorded across all studies, and were divided into three categories, pseudoaneurysms (0.06%); ischaemia and thrombosis (0.17%); haemorrhage and arterial transections (0.07%). Time taken to reach the diagnosis for each complication was longest in the ischaemia and thrombosis group (6.8 days), followed by pseudoaneurysm (3.5 days) and haemorrhage and transections (3.0 days).
CONCLUSION
TKA post-operative vascular complications are rare, but when they do occur they lead to limb and life threatening complications. This should be discussed with patients during the consent process. Current times to diagnosis represent missed opportunities to recognise arterial injury and facilitate rapid treatment of the complication. A very low threshold for seeking specialist input should be adopted, and any concern for vascular injury, such as unexplained perioperative bleeding, absent lower limb pulses in the post-operative period or unexplained severe pain should warrant immediate review by a vascular surgeon, and in centres where this is not possible, immediate blue-light transfer to the closest vascular centre.

Review
OBJECTIVE
This study aims to systematically review the management and outcomes of pediatric patients who develop intracranial pseudoaneurysm (IPA) following head trauma or iatrogenic injury.
METHODS
Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, a systematic literature review was performed. Additionally, a retrospective analysis was conducted on pediatric patients who underwent evaluation and endovascular treatment for IPA originating from head trauma or iatrogenic injury at a single institution.
RESULTS
Two hundred twenty-one articles in the original literature search. Fifty-one met inclusion criteria resulting in a total of 87 patients with 88 IPAs including our institution. Patients ranged in age from 0.5 months to 18 years. Parent vessel reconstruction was used as first-line treatment in 43 cases, parent vessel occlusion in 26, and direct aneurysm embolization (DAE) in 19. Intraoperative complications were observed in 3.00% of procedures. Complete aneurysm occlusion was achieved in 89.61% of cases. 85.54% of cases resulted in favorable clinical outcomes. The mortality rate after treatment was 3.61%. The DAE group had higher rates of aneurysm recurrence than other treatment strategies (P = 0.009). Patients with SAH had overall worse outcomes compared to patients who did not (P = 0.024). There were no differences in favorable clinical outcomes (P = 0.274) or complete aneurysm occlusion (P = 0.13) between primary treatment strategies.
CONCLUSIONS
IPAs were successfully obliterated, and favorable neurological outcomes were achieved at a high rate regardless of primary treatment strategy. DAE had a higher rate of recurrence than the other treatment groups. Each described treatment method in our review is safe and viable for the treatment of IPAs in pediatric patients.

Review
PURPOSE
To present two cases of Internal Carotid Artery (ICA) agenesis and conduct a systematic review to assess for associations with other anomalies and intracranial aneurysms.
METHODOLOGY
We performed a retrospective review of published cases of patients with ICA agenesis with intercavernous anastomosis in MEDLINE database on August 2022 using search terms "internal carotid artery", "agenesis" and "transcavernous anastomosis". We also included two cases of ICA agenesis with type D collateral that we encountered.
RESULTS
Total of 46 studies that included 48 patients and two of our cases resulted in 50 patients. Only 70% of studies reported the location of a collateral vessel of which more than two-thirds were on the floor of sella. More than half of the vessels connected cavernous segments of ICA. A1 segment ipsilateral to the side of ICA agenesis was absent in most of the cases but was not true for all cases. Aneurysm was seen in more than one-quarter of the patients. It can also mimic microadenoma as in prior reported cases as well as in one of our cases.
CONCLUSION
ICA agenesis with type D collateral is a rare anomaly but clinically relevant due to the increased risk of an aneurysm or mimic microadenoma or false alarm for occlusion of ICA but knowledge of this rare variant can help in better management of these patients.

BACKGROUND
Popliteal artery pseudoaneurysms are a rare but serious complication following total knee arthroplasty that have been traditionally managed with open surgical repair. Endovascular stenting, while relatively new, offers a promising alternative that is less invasive and may reduce the risk of perioperative complications.
METHODS
A systematic literature review was conducted, and all clinical reports in the English language from inception to July 2022 were identified. References were manually reviewed to identify additional studies. Demographics, procedural techniques, postprocedural complications, and followup data were extracted and analyzed using STATA 14.1. Additionally, we present a case of a patient with a popliteal pseudoaneurysm treated with a covered endovascular stent.
RESULTS
A total of 14 studies (12 case reports, 2 case series; n = 17) were included for review. In all cases, a stent-graft was placed across the popliteal artery lesion. In 5 out of 11 cases, popliteal artery thrombus was present and treated with adjacent modalities (i.e., mechanical thrombectomy, balloon angioplasty, etc.). Procedure success was reported in all cases without perioperative adverse events. Stents remained patent over a median followup of 32 weeks (interquartile range: 36). In all but one case, the patients experienced immediate symptom relief and had an uneventful recovery. For our case, at the 12-month followup the patient was asymptomatic, and ultrasound demonstrated vessel patency.
CONCLUSIONS
Endovascular stenting is a safe and effective treatment for popliteal pseudoaneurysms. Future studies should be aimed at evaluating the long-term outcomes of such minimally invasive techniques.

Meta-Analysis
BACKGROUND
The distal radial artery (DRA) access is an alternative to the conventional radial artery (CRA) access for coronary angiography and interventions and appears to be associated with reduced incidence of certain outcomes.
METHODS
A systematic review was performed to evaluate differences between DRA versus CRA access for coronary angiography and/or interventions. Following preferred reporting items for systematic review and meta-analysis-protocols guidelines, two reviewers independently selected studies published in the electronic databases (MEDLINE, EMBASE, SCOPUS, CENTRAL) from inception to October 10, 2022, followed by data extraction, meta-analysis, and quality assessment.
RESULTS
The final review included 28 studies with (total: 9151 patients [DRA: 4474; CRA: 4677]). Compared with CRA, DRA access was found to be associated with a shorter time to achieve hemostasis (mean difference, MD: -32.49 [95% confidence interval, CI: -65.53, -2.46], p < 0.00001), and reduced incidence of radial artery occlusion (RAO) (risk ratio, RR: 0.38 [95% CI: 0.25, 0.57], p < 0.00001), any bleeding (RR: 0.44 [95% CI: 0.22, 0.86], p = 0.02), and pseudoaneurysm (RR: 0.41 [95% CI: 0.18, 0.99], p = 0.05). However, DRA access has increased access time (MD: 0.31 [95% CI: -0.09, 0.71], p < 0.00001) and crossover rates (RR: 2.75 [95% CI: 1.70, 4.44], p < 0.00001). There were no statistically significant differences in other technical aspects and complications.
CONCLUSION
DRA access is a safe and feasible approach for coronary angiography and interventions. Compared to CRA, DRA provides a shorter hemostasis time, lower incidence of RAO, any bleeding, and pseudoaneurysm, and is associated with increased access time and crossover rates.

Review
Percutaneous scalpel tenotomy is frequently performed as part of congenital talipes equinovarus (CTEV) to correct the equinus deformity. The use of a scalpel is associated with complications such as neurovascular bundle damage and pseudoaneurysms. In the literature, a percutaneous large-bore needle has been found to be a safer alternative to a scalpel for performing tenotomies. The goal of this study was to conduct a systematic review and report a single-center case series on the use of percutaneous needle tenotomy in the treatment of CTEV. A Preferred Reporting Items of Systematic Review and Meta-analysis (PRISMA)-compliant literature search was conducted to identify studies describing the use of a percutaneous needle tenotomy in the treatment of idiopathic CTEV. A retrospective case series of patients with idiopathic CTEV treated with percutaneous needle tenotomy over a seven-year period from a single center were also conducted. The patients' demographics, the location of the clubfoot, and the Pirani score were all recorded. An analysis of descriptive statistics was carried out. Continuous data were expressed as mean and SD, whereas categorical variables were expressed as absolute numbers and percentages (%). The systematic review included eight papers with a total of 1026 feet and a mean age of 10.4 weeks (SD 5.9). There were 47 (0.04%) complications across all studies, with a pooled success rate of 95%. Eleven patients (16 feet) were included in the single-center case study. The patients' initial Pirani score was 4.8 (SD 1.5), with a final score of 0. (SD 0). Four complications occurred in the patient's cohort - one minor bleeding and three recurrences as a result of poor compliance with the post-tenotomy foot abduction brace. In conclusion, the percutaneous Achilles tenotomy of a CTEV foot with a large bore needle is a safe and effective alternative.

Meta-Analysis
AIM
To determine the risk of hepatic pseudoaneurysm after liver trauma in relation to the severity of liver injury.
METHODS
We performed a systematic review and meta-analysis in compliance with PRISMA statement standards (Registration Number: CRD42022328834). A search of electronic information sources was conducted to identify all studies reporting the risk of hepatic pseudoaneurysm after liver trauma. The JBI assessment tool was used to assess the risk of bias of the included studies. Random-effects models were applied to calculate pooled outcome data.
RESULTS
A total of 2030 patients from six studies were included. Based on the American Association for the Surgery of Trauma classification system, 21% had grade I injury; 33% grade II injury; 28% grade III injury; 12% grade IV injury and 5% grade V injury. The pooled risk of hepatic pseudoaneurysm was 1.8% (95% CI 1.1-2.5%). The risk was 0.4% (0-1.2%) in patients with grade I injury, 0.7% (0-1.7%) in patients with grade II injury; 1.5% (0.4-2.7%) in patients with grade III injury; 4.6% (1.4-7.7%) in patients with grade IV injury and 10.6% (1.8-22.9%) in patients with grade V injury. The average time between liver injury and detection of hepatic pseudoaneurysm was 6 days (95% CI 1-10) CONCLUSIONS: The risk of hepatic pseudoaneurysm after liver trauma increases as the severity of liver injury increases. Hepatic pseudoaneurysms are rare after grade I or grade II injuries, and increasingly common after grades III, IV and V injuries. We recommend routine surveillance imaging in patients with grade III to V injuries.
