Review
BACKGROUND
A persistent endoleak type II (ET II) after endovascular repair for aortic aneurysms is not always a benign condition and has been associated to sac expansion, rupture, and reintervention. A variety of different endovascular approaches are available for ET II treatment. The aim of this systematic review was to assess the currently available literature on transcaval embolization for ET II treatment after standard or complex endovascular aortic aneurysm repair.
METHODS
This systematic review protocol was registered to the PROSPERO (CRD42021289686). The PRISMA guidelines and patient, intervention, comparison, outcome (P.I.C.O.) model was followed. A data search of the literature was conducted, using PubMed, EMBASE via Ovid, and CENTRAL databases, until September 30, 2021. Only studies reporting on ET II embolization using the transcaval approach after endovascular aneurysm repair were included. Studies reporting on different type of endoleak treatment or any other embolization approach were excluded. The quality of studies was assessed using the Newcastle-Ottawa Scale. Primary outcomes were technical success and freedom from ET II persistence during follow-up; secondary outcomes were any postoperative complication associated with the transcaval embolization and need for reintervention.
RESULTS
The search yielded 2861 articles in total. Eight articles were included, reporting on 117 patients and 128 transcaval embolizations. The indication for treatment was ET II presence with sac expansion of more than 5 mm; in two studies, the presence of persistent endoleak has set the indication to intervene. The technical success was 91.4% (117/128); a variety of embolic materials were used, including coils, thrombin, and glue. Three cases of deep vein thrombosis were recorded and the remaining morbidity and mortality were null. Follow-up was ranging between 0 and 25 months. Out of 8 studies, persistent ET II rate was 12.8% and 18 reinterventions were performed (14.1%,), including 10 transcaval coil embolizations (56%). Sac expansion was reported in 11 cases, out of 3 studies (17%). Only one case of death, not associated with transcaval embolization, was recorded.
CONCLUSIONS
Transcaval embolization for ET II treatment presents a high technical success and low mortality in the early and mid-term period. ET II persistence rate is low during the available 12-month follow-up.

Meta-Analysis
BACKGROUND
Abdominal aortic aneurysms (AAAs) represent a significant burden of disease worldwide, and their rupture, without treatment, has an invariably high mortality rate. Whereas some risk factors for ruptured AAAs (rAAAs) are well established, such as hypertension, smoking, and female sex, the impact of seasonal and meteorologic variables is less clear. We systematically reviewed the literature to determine whether these variables are associated with rAAA.
METHODS
Review methods were according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We calculated pooled proportions and incidence rate ratios (IRRs) for the different months and seasons. Funnel plots were constructed to assess for publication bias. Given the poor methodologic quality of included studies, a sensitivity analysis was performed on better-quality studies, which scored 6 and above of 9 in the author-modified Newcastle-Ottawa Scale.
RESULTS
The pooled proportion of rAAA was highest in the autumn season (incidence rate, 26.6%; 95% confidence interval [CI], 25.6%-27.7%; I = 15.4%), followed by winter (incidence rate, 26.2%; 95% CI, 24.1%-28.2%; I = 72.4%), and lowest in summer (incidence rate, 21.1%; 95% CI, 19.3%-23.0%; I = 70.4%). The IRRs of rAAA were -6.9% (95% CI, -9.8% to -3.9%), -19.5% (95% CI, -22% to -16.8%), +10.5% (95% CI, 7.2%-13.9%), and +18.1% (95% CI, 15%-22%) in spring, summer, autumn, and winter compared with the remaining seasons, respectively (all P < .0001), thus affirming existence of seasonal variation. The pooled proportion of rAAA was highest in December (incidence rate, 8.9%; 95% CI, 7.1%-10.9%; I = 54.5%) but lowest in July (incidence rate, 5.7%; 95% CI, 4.2%-7.3%; I = 54.5%). The IRR was significantly the highest in January (IRR, 1.14; 95% CI, 1.01-1.29; P = .031) but lowest in July (IRR, 0.75; 95% CI, 0.65-0.87; P < .0001). There is also some evidence for a possible association with atmospheric pressure. Associations with temperature and daylight hours, however, are at best speculative.
CONCLUSIONS
Autumn and winter are significantly associated with a higher incidence of rAAAs, and autumn is associated with the highest rupture incidence of all the seasons. However, the inability to appropriately control for other confounding factors known to increase the risk of AAA rupture precludes any additional recommendations to alter current provision of vascular services on the basis of these data.

Review
Bicuspid aortic valve (BAV) disease presents a unique management challenge both pre- and post-operatively. 4D flow MRI offers multiple tools for the assessment of the thoracic aorta in aortic valve disease. In particular, its assessment of flow patterns and wall shear stress have led to new understandings around the mechanisms of aneurysm development in BAV disease. Novel parameters have now been developed that have the potential to predict pathological aortic dilatation and may help to risk stratify BAV patients in future. This systematic review analyses the current 4D flow MRI literature after aortic valve and/or ascending aortic replacement in bicuspid aortic valve disease. 4D flow MRI has also identified distinct challenges posed by this cohort at the time of valve replacement compared to standard management of tri-leaflet disorders, and may help tailor the type and timing of replacement. Eccentric pathological flow patterns seen after bioprosthetic valve implantation, but not with mechanical prostheses, might be an important future consideration in intervention planning. 4D flow MRI also has promising potential in supporting the development of artificial valve prostheses and aortic conduits with more physiological flow patterns.

Review
BACKGROUND
Aortic aneurysms occur when the aorta, the body's largest artery, grows in size, and can occur in the thoracic or abdominal aorta. The approaches to repair aortic aneurysms include directly exposing the aorta and replacing the diseased segment via open repair, or endovascular repair. Endovascular repair uses fluoroscopic-guidance to access the aorta and deliver a device to exclude the aneurysmal aortic segment without requiring a large surgical incision. Endovascular repair can be performed under a general anesthetic, during which the unconscious patient is paralyzed and reliant on an anesthetic machine to maintain the airway and provide oxygen to the lungs, or a loco-regional anesethetic, for which medications are administered to provide the person with sufficient sedation and pain control without requiring a general anesthetic. While people undergoing general anesthesia are more likely to remain still during surgery and have a well-controlled airway in the event of unanticipated complications, loco-regional anesthesia is associated with fewer postoperative complications in some studies. It remains unclear which anesthetic technique is associated with better outcomes following the endovascular repair of aortic aneurysms.
OBJECTIVES
To evaluate the benefits and harms of general anesthesia compared to loco-regional anesthesia for endovascular aortic aneurysm repair.
SEARCH METHODS
We used standard, extensive Cochrane search methods. The latest search was 11 March 2022.
SELECTION CRITERIA
We searched for all randomized controlled trials that assessed the effects of general anesthesia compared to loco-regional anesthesia for endovascular aortic aneurysm repairs.
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methods. Our primary outcomes were: all-cause mortality, length of hospital stay, length of intensive care unit stay. Our secondary outcomes were: incidence of endoleaks, requirement for re-intervention, incidence of myocardial infarction, quality of life, incidence of respiratory complications, incidence of pulmonary embolism, incidence of deep vein thrombosis, and length of procedure. We planned to use GRADE methodology to assess the certainty of evidence for each outcome.
MAIN RESULTS
We found no studies, published or ongoing, that met our inclusion criteria.
AUTHORS' CONCLUSIONS
We did not identify any randomized controlled trials that compared general versus loco-regional anesthesia for endovascular aortic aneurysm repair. There is currently insufficient high-quality evidence to determine the benefits or harms of either anesthetic approach during endovascular aortic aneurysm repair. Well-designed prospective randomized trials with relevant clinical outcomes are needed to adequately address this.

Review
Ortner's syndrome (OS), also called cardiovocal syndrome, is a rare condition hallmarked by left recurrent laryngeal nerve palsy due to underlying cardiopulmonary disease. The purpose of this review is to systemically analyze the existing literature for cases of OS to outline typical presentation, methods of diagnosis, and management of these patients. Case reports, case series, and cohort studies describing OS between 1955 and 2021 were identified. Individual manuscripts were reviewed for clinical features, presentation, and management. A total of 117 patient cases were gathered from 92 published articles. Common symptoms included hoarseness, dyspnea, cough, and dysphagia. The most common associated comorbidity was aortic aneurysm (41%), followed by pulmonary hypertension (35%), mitral stenosis (17%), and hypertension (12%). Among those who were managed surgical intervention, 85.4% reported improvement in their hoarseness. While historically OS was associated with mitral stenosis, in recent decades, aortic aneurysms and dilation of the pulmonary artery from pulmonary hypertension have emerged as primary etiologies of OS. Therefore, OS should be considered in any patient presenting with hoarseness and history of cardiopulmonary disease. Surgical intervention in appropriate candidates resolves OS in most cases.

Review
OBJECTIVES
The aim of this paper was to review the literature on temporary abdominal closure (TAC) after abdominal aortic aneurysm (AAA) repair.
METHODS
This was a systematic review of observational studies. A PubMed, EMBASE and Cochrane search from 2007 to July 2015 was performed combining the Medical Subject Headings "aortic aneurysm" and "temporary abdominal closure", "delayed abdominal closure", "open abdomen", "abdominal compartment syndrome", "negative pressure wound therapy", or "vacuum assisted wound closure".
RESULTS
Seven original studies were found. The methods used for TAC were the vacuum pack system with (n = 1) or without (n = 2) mesh bridge, vacuum assisted wound closure (VAWC; n = 1) and the VAWC with mesh mediated fascial traction (VACM; n = 3). The number of patients included varied from four to 30. Three studies were exclusively after open repair, one after endovascular aneurysm repair, and three were mixed series. The frequency of ruptured AAA varied from 60% to 100%. The primary fascial closure rate varied from 79% to 100%. The median time to closure of the open abdomen was 10.5 and 17 days in two prospective studies with a fascial closure rate of 100% and 96%, respectively; the inclusion criterion was an anticipated open abdomen therapy time ≥5 days using the VACM method. The graft infection rate was 0% in three studies. No patient with long-term open abdomen therapy with the VACM in the three studies was left with a planned ventral hernia. The in hospital survival rate varied from 46% to 80%.
CONCLUSIONS
A high fascial closure rate without planned ventral hernia is possible to achieve with VACM, even after long-term open abdomen therapy. There are, however, few publications reporting specific results of open abdomen treatment after AAA repair, and there is a need for randomized controlled trials to determine the most efficient and safe TAC method during open abdomen treatment after AAA repair.

Review
Situs viscerum inversus (SVI) is a very rare condition in that abdominal and thoracic organs are located reversed. Abdominal aortic aneurysm (AAA) is a life-threatening pathology due to progressive aortic enlargement until the rupture. The association between SVI and AAA is very infrequent. The aim of this study is to identify the surgical procedures available to treat AAA in SVI. We performed a literature review of all studies about AAA in SVI patients, analyzing PubMed/MEDLINE, EMBASE, Web of Science (WOS), Google Scholar databases. The survey includes all publications until June 2023. The outcomes include demographic findings, type of surgical procedure, intraoperative and postoperative complications, follow-up. A total of 12 studies, including 12 patients, were considered eligible for the review. AAA mean size was 70.5 mm (range: 55-90 mm); the most common localization was in the infrarenal aortic portion. 6 studies reported data on elective surgery, and 6 on emergency procedures. In one case endovascular treatment was performed. No intraoperative complications are reported; 3 postoperative complications are registered. Medium follow-up period was 13.5 months (range: 3-60). According to the available literature, the treatment of AAA in SVI is feasible and does not show an incremented morbidity compared to patients with a normal visceral configuration. This treatment seems to be effective also in case of endovascular treatment. AAA treatment in SVI should be performed (especially in elective settings) in high volume centers where it is possible to bring on collaboration across different surgical specialists.

Meta-Analysis Review
BACKGROUND
Studies have investigated the effects of gender on vascular surgery care. However, to the best of our knowledge, no comprehensive synthesis of the literature has been performed on the presentation severity and postoperative outcomes for abdominal aortic aneurysms (AAAs), carotid artery stenosis (CAS), peripheral artery disease (PAD), and type B aortic dissection (TBAD). We conducted a systematic review and meta-analysis of the sex and gender differences in the presentation severity and outcomes for patients who had undergone major vascular surgery.
METHODS
The MEDLINE, Embase, and Cochrane CENTRAL databases were searched from their inception to December 2020. All observational studies and randomized controlled trials that had evaluated the gender differences in presentation severity or outcomes for patients who had undergone open or endovascular AAA or TBAD repair, carotid endarterectomy or stenting, or lower extremity bypass or angioplasty were included. The presentation severity was defined as follows: AAA (symptomatic or ruptured vs asymptomatic), carotid artery disease (symptomatic vs asymptomatic), PAD (chronic limb-threatening ischemia [CLTI] vs claudication), and TBAD (complicated vs uncomplicated). The postoperative outcomes included long-term mortality, stroke, amputation, revascularization, and graft and/or stent thrombosis. A random effects model was used to derive the odds ratios (ORs), risk ratios (RRs), and 95% confidence intervals (CIs).
RESULTS
A total of 236 studies met the inclusion criteria for our systematic review. Of the 236 studies, 86 (n = 2,099,534 patients), 62 (n = 2,300,888 patients), 28 (n = 2,394,143 patients), and 4 (n = 4525 patients) had evaluated the effects of gender on the outcomes for patients with AAA, CAS, PAD, and TBAD, respectively. The female patients were more likely to have presented with a ruptured AAA (OR, 1.18; 95% CI, 1.09-1.28) and CLTI (OR, 1.10; 95% CI, 1.02-1.19) than were the male patients. The all-cause mortality for those with an AAA (RR, 1.35; 95% CI, 1.20-1.52) and those with PAD (RR, 1.14; 95% CI, 1.05-1.23) was higher for the women. However, the female patients with CAS had had lower all-cause mortality (RR, 0.85; 95% CI, 0.76-0.94). No sex differences were found in the TBAD outcomes.
CONCLUSIONS
We found that female patients who had undergone vascular surgery were associated with more severe disease at presentation, with a greater proportion of ruptured AAAs and CLTI. This potentially contributes to the higher mortality rates for female patients with AAAs and PAD compared with male patients. Future studies are needed to evaluate the reasons for these disparities, and greater efforts are required to support women in receiving more timely vascular surgical care.

Review
BACKGROUND Patient volume is assumed to affect quality, whereby complex procedures are best performed by those who perform them frequently. We have conducted a systematic review of the research on the association between patient volume and quality of vascular surgery. In this article we describe the outcomes for abdominal aortic aneurysm surgery.MATERIAL AND METHOD We undertook systematic searches in relevant databases. We searched for systematic reviews, and randomised and observational studies. The search was concluded in December 2015. We have summarised the results descriptively and assessed the overall quality of the evidence.RESULTS Forty-six observational studies fulfilled our inclusion criteria. We found a possible association for both hospital and surgeon volume. Higher patient volume may possibly be associated with lower 30-day mortality and lower hospital mortality for both open and endovascular surgery. Although the association appears to apply to both elective and acute hospitalisations, there is greater uncertainty with regard to the most ill patients. For hospital volume there may also be fewer complications for open and endovascular surgery, as well as for all surgery assessed as a whole. We considered the evidence base to be medium to very low quality.INTERPRETATION We found a possible correlation between patient volume and quality indicators such as mortality and complications. It may be advantageous to allocate planned procedures to institutions and surgeons with high volume, while this is less certain with regard to acute hospitalisations.

OBJECTIVE
The aim of this study was to determine the association between fluoroquinolones (FQs) use, the risk of aortic aneurysm or dissection (AAD), and the prognosis of patients with pre-existing AAD.
MATERIALS AND METHODS
We searched PubMed, EMBASE, CENTRAL, Scopus, and Web of Science on 31 March 2022. Observational studies that evaluated the association of FQs with AAD risk in the general population or FQs with the prognosis of patients with preexisting AAD and presented adjusted effect estimates were included. Two reviewers assessed study eligibility, extracted data, and assessed the risk of bias and certainty of evidence using GRADE.
RESULTS
Of the 13 included studies, 11 focused on the association of FQs with AAD incidence, and only one study investigated the association of FQs with the patient with AAD prognosis. FQ use was associated with an increased risk of AAD within 30 days (RR: 1.42; 95% CI: 1.11-1.81; very low certainty) and 60 days (RR: 1.44; 95% CI: 1.26-1.64; low certainty). Specifically, the association was significant when compared with amoxicillin, azithromycin, doxycycline, or no antibiotic use. Furthermore, patients with preexisting AAD exposure to FQ had an increased risk of all-cause mortality (RR: 1.61; 95% CI: 1.50-1.73; moderate certainty) and aortic-specific mortality (RR: 1.80; 95% CI: 1.50-2.15; moderate certainty), compared to the non-exposed FQ group within a 60-day risk period.
CONCLUSION
FQs were associated with an increased incidence of AAD in the general population and a higher risk of adverse outcomes in patients with preexisting AAD. Nevertheless, the results may be affected by unmeasured confounding factors. This should be considered by physicians contemplating using FQs in patients with aortic dilation and those at high risk of AAD.
