Low-profile versus standard-profile multibranched thoracoabdominal aortic stent grafts

Abstract

LPSGs had similar safety profile and midterm outcomes compared with the SPSGs for treatment of pararenal and TAAA. The substitution of LPSGs for SPSGs lowered the number of patients who required conduit insertion to avoid access artery injury, especially in women, thereby reducing an otherwise striking gender difference.

Cerebrovascular Complications After Upper Extremity Access for Complex Aortic Interventions: A Systematic Review and Meta-Analysis

“…Four studies did not make a statement about the severity of the event but reported that four patients with a cerebrovascular accident did fully recover, one patient recovered moderately and one patient did not recover at all [12,23,25,27]. One article did not make a statement about the clinical severity or the recovery [26]. Four studies included in the review reporting cerebrovascular events did not mention the affected brain territory nor the patient's clinical symptoms [11,19,22,23].…”

“…Aneurysm extent included 262 thoracoabdominal aortic aneurysms [10,11,21,[27][28][29] and 867 complex (from juxtarenal to paravisceral) abdominal aortic aneurysms [10-12, 16, 18-20, 23-25, 27, 28]. Two studies did not provide aneurysm classification [22,26]. The mean diameter was reported by seven studies and ranged from 50 mm to 74 mm, and the overall mean diameter was 64 mm [11,18,19,[23][24][25].…”

“…All studies stated which aortic intervention was performed. In total, 583 chimney EVAR [12,16,19,20,24,25], 28 chimney endovascular aneurysm sealing (EVAS) [23], 210 fenestrated EVAR [18,20,22,27,28], 249 fenestrated/ branched EVAR [11,29] and 206 branched EVAR [10,21,26] were performed. The mean procedure time was reported by ten studies and ranged from 105 to 600 min.…”

“…Four studies did not report how many aortic side branches were treated (Table 1) [10,12,25]. [11,12,16,[18][19][20][21][22][23][24][25][26][27][28][29], right (n = 148) [10-12, 18, 22] or bilateral (n = 100) [12,19,20,24] upper extremity access for the treatment of aortic aneurysms. One article had a discrepancy between the total number of patients and the size of each group, mentioning 425 treated patients but 434 used access strategies [12].…”

Mid-term Outcomes of Endovascular Repair of Ruptured Thoraco-abdominal Aortic Aneurysms with Off the Shelf Branched Stent Grafts

“…16 Low profile stent grafts increase the applicability of b-EVAR with comparable outcomes to the standard profile version. 7,17 Striving for good long-term results has changed some of the authors' practices. Any bridging stent is liberally reinforced whenever it might be jeopardised within a small or angulated aorta, or has to pass through a suprarenal bare stent of a previous infrarenal stent graft ( Fig.…”
