Abstract:
Methods:From Jan 2019 to Nov 2021, 20 patients underwent 3D printed template assisted pre-fenestration of stent graft with reducing-diameter tie technique and branched stents for the EVAR at the three hospitals. The clinical data patients were collected and analyzed.Results:All the 20 cases underwent 3D printed template assisted pre-fenestration of stent graft according to the data of pre-operative the computed tomographic angiography (CTA). EVAR was successfully performed in all patients(included 2 cases with one fenestration,5 cases with 2 fenestration,10 cases with 3 fenestration and 3 cases with 4 fenestration). Fifty-four reinforced fenestrations (20 in right renal artery, 18 in left renal artery, 13 in superior mesenteric artery and 3 in celiac artery) were performed. During the follow-up period (mean 14.6 months), 1 case died, and the one-stage patency rate of splanchnic artery branch stent was 98.1%. Four patients had endoleak, 1 patient died of intracranial hemorrhage during postoperative period. None of patients had postoperative paraplegia or organ ischemia.Conclusions:3D printed template assisted pre-fenestration of stent graft with reducing-diameter tie technique is feasible for EVAR in the treatment of complex abdominal aortic aneurysms and dissections. The technique is capable to reinforce the blood supply of visceral arteries with satisfied short-term effectiveness.Ojective:To evaluate 3D printed template assisted pre-fenestration of stent graft with reducing-diameter tie technique and branched stents for the endovascular aortic aneurysm repair (EVAR).
