Prognostic significance of large diameter proximal aortic neck in endovascular aneurysm repair.

Prognostic significance of large diameter proximal aortic neck in endovascular aneurysm repair. Vasa. 2020 Jan 06;:1-10 Authors: Antoniou GA, Alfahad A, Antoniou SA, Badri H Abstract Background: Adverse morphological features of the proximal aortic neck have been identified as culprits for late failure after endovascular aneurysm repair (EVAR). Our objective was to investigate the prognostic role of wide proximal aortic neck in EVAR. Methods: We conducted a review of the literature in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines to identify studies comparing outcomes of EVAR in patients with large versus small proximal aortic neck. A meta-analysis of time-to-event data was performed with the inverse-variance method and the results were reported as summary hazard ratio (HR) and 95 % CI. We applied random-effects models of meta-analysis. Results: We identified 9 observational studies reporting on a total of 7,682 patients (1,961 with large diameter and 5,721 with small diameter neck). The hazard of death (HR 1.57, 95 % CI 1.23-2.01; P = 0.0003), aneurysm-related reintervention (HR 2.06, 95 % CI 1.23-3.45; P = 0.006), type Ia endoleak (HR 6.69, 95 % CI 4.39-10.20; P

Conclusions: PsR before EVAR reduced endovascular procedure time, and our results indicate that it might improve technical success, but further studies are needed to confirm those results. PMID: 32057277 [PubMed - as supplied by publisher]

In this case, a 79-year-old male presented with new anteroseptal Q waves and T-wave inversions across the precordial leads following an otherwise uneventful endovascular repair of his thoracoabdominal aortic aneurysm. The patient had no history of cardiac disease and had undergone a dobutamine stress echocardiogram within the preceding 6 months that showed no evidence of inducible ischemia. Nevertheless, routine postoperative electrocardiogram (EKG) revealed new Q waves and T-wave inversions and transthoracic echocardiogram that demonstrated akinesis of the left ventricle (LV) apex with chronic-appearing apical thrombus. W...

We reported the first total endovascular repair for a Kommerell diverticulum with chronic retrograde type A aortic dissection. We conducted total endovascular repair with a unibody single-branched stent-graft combined with chimney technique for reconstruction of both subclavian arteries. Completion angiography showed complete exclusion of the primary entry tear without endoleak and patency of all stent-grafts, and CTA at follow-up showed significant remodeling of the false lumen. In this case, we show that total endovascular repair is feasible and safe in selective patients of this kind.

Extension of aortic disease to the aortic arch is common, frequently requiring cervical debranching procedures to maintain patency of supra-aortic branches. Endovascular aortic arch repair is an attractive alternative in the treatment of aortic arch disease for high-risk patients with thoracoabdominal diseases encroaching on the arch. The aim of our study was to report our experience of fenestrated endovascular repair in the aortic arch.

Mycotic aneurysms of the abdominal aorta (MAAA) can be treated by open repair (OR) or endovascular aneurysm repair (EVAR). This nationwide study provides an overview of the situation of MAAA treatment in The Netherlands in  2016.

Our objective was to investigate whether patients undergoing standard endovascular aneurysm repair (EVAR) outside the instructions for use (IFU) have worse outcomes than patients treated within IFU.

The neutrophil-lymphocyte ratio (NLR) is an inexpensive and useful inflammatory marker that incorporates the balance of the innate (neutrophil) and adaptive (lymphocyte) immune responses. Data exist on the association between NLR and mortality in various coronary diseases and in cancer surgery, but there is a paucity of data on the impact of preoperative NLR on vascular surgical outcomes. The aim of this study was to evaluate the relationship between preoperative NLR and elective endovascular aortic aneurysm repair (EVAR) outcome.

The aim was to report indications, technical aspects, and outcomes of a multicentre experience of late open conversions (LOCs) after endovascular abdominal aneurysm repair (EVAR), in order to identify risk factors which may influence early morbidity and mortality rates, and long term survival.

Some studies suggest celiac artery coverage during elective endovascular thoracoabdominal aortic aneurysm (TAAA) repair is safe given sufficient collateralization of visceral organ perfusion from the superior mesenteric artery. However, there is concern that celiac artery coverage may lead to increased risk of foregut or spinal cord ischemia with an attendant increased risk of mortality. We sought to investigate rates of bowel ischemia, spinal cord ischemia and 30-day mortality associated with celiac artery coverage during TEVAR and complex EVAR.
