Standard off-the-shelf versus custom-made multibranched thoracoabdominal aortic stent grafts

Abstract

For patients with suitable anatomy, the use of SSGs for TAAA and PRAA repair results in significantly shorter wait times to surgery and is as safe, effective, and durable in the midterm compared with CSGs.

Standard “off-the-shelf” multibranched thoracoabdominal endograft in urgent and elective patients with single and staged procedures in a multicenter experience

“…Technical success in this study was encouraging. Overall mortality #30 days (4%) was in line with other published series dedicated to the t-Branch device (range, 0%-6%) [14][15][16] despite the majority of patients electively treated in these studies. The outcome was also lower than in other CSG cohorts (range, 7%-11.6%).…”

“…To date, there have been few published studies dedicated to the Zenith t-Branch device in selected patients (most were treated electively) 14,15 or a small cohort (n ¼ 17) of urgent/emergent repair. 16 This study is the largest series of elective and urgent/emergent patients (n ¼ 32 [44%]) available.…”

“…TVV patency was high, with a low incidence of branch occlusion throughout the follow-up, in line with other t-Branch reported series (range, 2%-7%). [14][15][16] In contrast with the technique described by Bisdas et al 14 and Fernandez et al, 15 relining of the branches was not routinely performed; some authors 27,29 have found that it may be a risk factor for occlusion. The authors hypothesize a relationship between relining with BMS and TVV occlusion, and this justifies further investigations.…”

“…The initial clinical experiences showed interesting early results in both elective and urgent settings, but larger cohorts and longer follow-up are needed to verify this device. [13][14][15][16] The Italian mbEVAR study group performed a retrospective study to assess immediate and midterm outcomes for both urgent and elective TAAA patients treated with the first off-the-shelf mbEVAR, with a single-step or staged surgical approach.…”

Balloon-grab technique to bridge steep renal artery during endovascular thoracoabdominal aortic aneurysm repair: technical note

“…Moreover, Fernandez et al compared EVAR using Zenith t-branch in the treatment of patients with suitable anatomy to EVAR using custom-made stent grafts. Midterm results were very similar, but waiting time for the former one was significantly shorter (p < 0.01) [9]. Thus, the endograft was considered to be a potential off-the-shelf prosthesis for TAAA.…”
