The risk of aortic abdominal aneurysm (AAA) rupture increases with an increasing aneurysm diameter. However, the effect of the AAA diameter on late outcomes after aneurysm repair is unclear. Therefore, we assessed the association of a large AAA diameter with late outcomes for patients undergoing open and endovascular AAA repair.

We identified all patients who had undergone elective open or endovascular infrarenal aneurysm repair from 2003 to 2016 in the Vascular Quality Initiative linked to Medicare claims for long-term outcomes. A large AAA diameter was defined as a diameter >65mm. We assessed the 5-year reintervention, rupture, mortality, and follow-up rates. We constructed propensity scores and used inverse probability-weighted Kaplan-Meier estimations and Cox proportional hazard models to identify independent associations between large AAA repair and our outcomes.

Of the 21,119 aneurysm repairs identified, 15.2% were for large AAAs. Of the 21,119 repairs, 19,017 were endovascular and 2102 were op3% vs 70.6%).

The 5-year adjusted reintervention, ruptures, mortality, and loss to follow-up rates for patients who had undergone large AAA EVAR were higher than those for patients who had undergone small AAA EVAR and large AAA open repair. Therefore, for patients with large AAAs who are medically fit, open repair should be strongly considered. Furthermore, these findings highlight the necessity for rigorous long-term follow-up after EVAR.

We have reported the short-term outcomes regarding the safety of the off-the-shelf Zenith t-Branch multibranched thoracoabdominal stent-graft (William Cook Europe ApS, Bjaeverskov, Denmark) in a postmarket, multicenter study.

Patients who had been treated with the t-Branch device from September 2012 to November 2017 at three European centers were either prospectively or retrospectively enrolled in the present study. Device implantation and postprocedural follow-up were performed according to the standard of care at each center. The primary objectives of the present study were to assess the procedure-related mortality and morbidity at 30days and 1year and to assess the presence of endoleaks, device integrity, and stent-graft and branch vessel patency.

A total of 80 patients were included in the present study (mean age, 71.0± 7.4years; 70.0% male). Most (n= 77) had been treated for thoracoabdominal aortic aneurysms (TAAAs) and the rest for dissection (n= 3). Most TAAAs were stable (72.7%; 56 of 77). The rc artery branches were patent and one left renal and one right renal branch were occluded. At 1year, occlusion had developed in three bridging stent-grafts for the celiac artery, one for the left renal artery, and two for the right renal artery.

The t-Branch device appears safe, with good 30-day and 1-year mortality and morbidity in the present study, including both stable and symptomatic cases.

Patients with peripheral arterial disease (PAD) are predisposed to postprocedure adverse limb events (ALE). Previous single-center studies investigating the relationship between baseline C-reactive protein (CRP) levels and postprocedure ALE have reported inconsistent results. Therefore, we performed a systematic review and meta-analysis of reported data to determine the association between CRP levels and the occurrence of postprocedure ALE in patients with PAD.

Studies investigating the association between the CRP levels and postprocedure ALE (ie, target vessel revascularization, amputation, restenosis, disease progression, composite endpoint of any of these ALE) were identified in the Medline, EMBASE, and Cochrane databases. Meta-analyses of the reported hazard ratios (HRs) were conducted using an inverse variance-weighted random effects model. Subgroup analyses were performed to determine the differences in outcomes between open surgery and endovascular treatment. Pooled estimates are reported as HRs to compare higher and lower CRP levels and odds ratio or relative risk per unit increase in log
CRP (natural logarithm C-reactive protein).

A total of eight studies involving 1460 participants were included in our meta-analysis. Patients with higher baseline CRP levels had a greater risk of ALE (HR, 1.09; 95% confidence interval, 1.00-1.18; P= .04) compared with those with lower baseline CRP levels. The pooled estimate of odds ratio and relative risk for ALE was 2.25 (95% confidence interval, 1.49-3.41; P< .01) per unit increase in log
CRP. Subgroup analyses found no significant differences in the pooled estimates in studies of open surgery vs endovascular treatment.

Our results have demonstrated that high baseline CRP levels are predictive of ALE in patients with PAD after lower limb revascularization.

Despite promising early results, mid-term failures of the Nellix endovascular aneurysm sealing (EVAS) system (Endologix Inc, Irvine, Calif) have been reported at higher than expected rates. The management of proximal endoleaks and migration differs from those after conventional endovascular aortic aneurysm repair (EVAR) owing to the peculiar design of the Nellix device. In the present study, we report a monocentric experience in the management of EVAS complications using various techniques. We also performed a comprehensive review of the relevant literature on both open surgical and endovascular management of proximal failure of EVAS from the MEDLINE database.

We retrospectively analyzed the reinterventions for type Ia endoleak and migration after elective infrarenal EVAS at our institution. We collected preoperative, intraoperative, and follow-up data. Open and endovascular techniques are described. Overall survival, aortic-related mortality, and the technical success rate (rate of exclusion of endoleaksrs to be an effective alternative to more complex interventions, although it requires further studies for validation.
Stress testing is often used before abdominal aortic aneurysm (AAA) repair. link2 Whether stress testing leads to a reduction in cardiac events after AAA repair has remained unclear. Our objective was to study the national stress test usage rates and compare the perioperative outcomes between centers with high and low usage of stress testing.

We used the Vascular Quality Initiative to study patients who had undergone elective endovascular AAA repair (EVAR) or open AAA repair (OAR). We measured the usage rates of stress testing across centers and compared the Vascular Study Group of New England cardiac risk index (VSG-CRI) among patients who had and had not undergone preoperative stress testing. We determined the rate of major adverse cardiac events (MACE), a composite of perioperative myocardial infarction, stroke, heart failure exacerbation, and death across the centers. We compared the MACE and 1-year mortality between the centers in the highest quintile of stress test usage and the lowest quintile.

We studing should be used more selectively, given these findings and the associated costs of widespread testing.
Three-dimensional ultrasound (3D-US) has already demonstrated improved reproducibility with a high degree of agreement (intermodality variability), reproducibility (interoperator variability), and repeatability (intraoperator variability) compared with conventional two-dimensional ultrasound (2D-US) when estimating the maximum diameter of native abdominal aortic aneurysms (AAAs). link3 The aim of the present study was, in a clinical, multicenter setting, to evaluate the accuracy of 3D-US with aneurysm model quantification software (3D-US abdominal aortic aneurysm [AAA] model) for endovascular aortic aneurysm repair (EVAR) sac diameter assessment vs that of computed tomography angiography (CTA) and 2D-US.

A total of 182 patients who had undergone EVAR from April 2016 to December 2017 and were compliant with a standardized EVAR surveillance program were enrolled from five different vascular centers (Rigshospitalet, Copenhagen, Denmark; Catharina Ziekenhuis, Eindhoven, Netherlands; L'hospital de la Timone, Paris, cant difference compared with CTA for measuring the anteroposterior diameter, indicating less bias for 3D-US compared with 2D-US. Thus, 3D-US with AAA model software is a viable modality for anteroposterior diameter assessment for surveillance after EVAR.

Thoracic endovascular aortic repair (TEVAR) has been shown to effectively treat malperfusion associated with acute type B thoracic aortic dissection (TBAD). A subset of patients might still require adjunctive peripheral or visceral artery branch interventions during TEVAR to remedy persistent end organ malperfusion. Our objectives were to determine the incidence of these adjunctive interventions and to compare the outcomes between patients who had and had not undergone such interventions.

We performed a retrospective review of the TEVAR and complex EVAR module of the Vascular Quality Initiative from 2010 to 2019 to identify all patients treated for malperfusion due to acute TBAD. The anatomic branch and procedure performed at TEVAR were recorded. The 30-day mortality, need for reintervention, complication rates, and overall survival were compared between these patients stratified by adjunctive intervention status.

A total of 426 patients had undergone TEVAR for acute TBAD with end organ malperfusion. Ofripheral and visceral artery branch interventions in conjunction with TEVAR for acute TBAD with malperfusion occurred in one third of index cases, but did not predispose patients to worse overall outcomes. Adjunctive arterial branch interventions should be included in the treatment paradigm for acute TBAD with end organ malperfusion that does not improve with primary entry tear coverage alone.
