Results of complex aortic stent grafting of abdominal aortic aneurysms stratified according to the proximal landing zone using the Society for Vascular Surgery classification

Abstract

We have shown that the extent of the aneurysm repair as determined by the proximal sealing zone is associated with outcome. Mortality, operative duration, blood loss, and hospital stay all significantly increased as the zones ascended. These data also validate the use of the proposed new classification based on aortic anatomy.

Comparison of outcomes for double fenestrated endovascular aneurysm repair versus triple or quadruple fenestrated endovascular aneurysm repair in the treatment of complex abdominal aortic aneurysms

“…Sveinsson et al 12 reported outcomes in 288 patients from Malmö and Lille and concluded that a more complicated stent graft design did not lead to increased risk for perioperative mortality, as confirmed by our study. In contrast, Patel et al, 5 in a study of 150 patients, showed that operative mortality increased significantly with a more proximal landing zone with complex stent graft configuration.…”

“…The complexity may result in higher perioperative mortality and morbidity as a result of the longer operative time, prolonged catheter and wire manipulations, increased blood loss, increased contrast use, and increased coverage of segmental arteries and associated spinal cord ischemia (SCI). 5 The present study investigated whether stent graft design complexity affects perioperative outcomes of FEVAR in a high-volume endovascular center.…”

Graft Complexity–Related Outcomes of Fenestrated Endografting for Abdominal Aortic Aneurysms

“…Some authors include type IV TAAAs in the statistical analysis as well as patients treated with branched stent-grafts. 2,8 Furthermore, there is a lack of consensus regarding how to classify JAAs and SAAs and the subsequent extent of repair. Result stratification has been carried out according to several different standards, with other authors comparing renal-only fenestrations to more complex designs, while others apply the aneurysm zone classification or the Society for Vascular Surgery/American Association for Vascular Surgery anatomical severity score.…”

“…Result stratification has been carried out according to several different standards, with other authors comparing renal-only fenestrations to more complex designs, while others apply the aneurysm zone classification or the Society for Vascular Surgery/American Association for Vascular Surgery anatomical severity score. [7][8][9] It is our belief that stratification of FEVAR results in the abdominal aorta should be limited to abdominal aortic pathology. The current series compared solely patients with JAAs and SAAs excluding patients with TAAAs.…”

Fenestrated stent grafts for the treatment of complex aortic aneurysm disease: A mature treatment paradigm

“…85 Series from referral centers have included between 45 and 607 patients, with 117-1907 target vessels. 5,10,29,[32][33][34]39,80,97 Up to July 2012, a total of 2463 target vessels have been accessed through fenestrations and/or scallops, all within the use of the fenestrated Zenith SG. 20 Overall, early target vessel patency rate ranges from 90.5% to 99.7%.…”
