Multibranched Stent-Grafts for the Treatment of Thoracoabdominal Aortic Aneurysms

Abstract

Use of multibranched stent-grafts in the treatment of TAAAs and PRAAs appears to be feasible and safe based on satisfactory early outcomes in the limited literature available to date. Long-term surveillance and further studies are essential to determine the durability of this technique.

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

“…The SCI rate (3%) reported in this series was lower than the rates reported in literature dedicated to TAAA surgery (range, 5%-13.2%) 1,2 and mbEVAR (range, 5%-17%). 14,16,25 In the two cases of SCI, both patients received minimum aortic coverage (Crawford type IV), and intraoperative prophylactic CSFD was not given. Extended aortic coverage has been identified as one of the most important risk factors for SCI.…”

Long-Term Patency of Visceral Vessels After Thoracoabdominal Aortic Repair

“…Open repair of thoracoabdominal aortic aneurysms (TAAAs) is an extraordinary challenge for both vascular surgeons and patients. Consistent outcome data have been reported by highvolume centers with 30-day mortality rates lower than 10% and improved long-term survivals [1]. The development of devices and techniques have allowed total endovascular treatment of TAAA with fenestrated (FEVAR) or branched (BEVAR) endografts [2][3][4][5][6].…”

“…Late patency of visceral branches following total endovascular TAAA repair (FEVAR and/ or BEVAR) is an open issue. Different groups reported excellent early patency rates, followed in the midterm by a slow but progressive loss of visceral branches [1,26,27]. Late occlusion involves VVs at different rates, with a significant prevalence of renal arteries compared to other vessels.…”

One-stage replacement of the aorta from arch to thoracoabdominal region

“…Patient survival was 59%, and freedom from any reintervention was 53% at 5 years. Hu and colleagues 16 screened 370 articles in which multibranched stent grafts were used. However, only 4 articles encompassing 185 patients (mean age 71.1 years) were aligned with the inclusion criteria.…”
