Management strategy of iliac artery difficulty in abdominal aortic aneurysm endovascular repair / 国际外科学杂志

ABSTRACT

Objective:To explore the strategies for the treatment of difficult iliac artery approach in endovascular repair of abdominal aortic aneurysm.Methods:The clinical data of 275 patients with abdominal aortic aneurysm who underwent endovascular surgery at the Department of Vascular Surgery, People′s Hospital of Xinjiang Uygur Autonomous Region from March 2010 to March 2019 were retrospectively analyzed, and the general clinical data such as age, gender, and comorbidities of the patients were recorded. The resource index was to carry out corresponding measures to perform surgery for patients with difficult access, analyze the incidence of the type of difficult access, treatment measures and effects.Results:Two hundred and seventy-five patients underwent endovascular repair, 78 of them (28.3%) had difficulty in accessing the iliac artery, including 29 cases (10.5%) with mild iliac artery stenosis, 7 cases (2.54%) with severe stenosis, and 3 cases with occlusion ( 1.09%), 39 cases (14.2%) were twisted. For patients with vascular twist, super-hard guide wire was used to correct iliac artery angulation. For patients with iliac artery stenosis, balloon dilation was performed. For severe stenosis, the artificial blood vessel was passed through the lateral peritoneum. After road transplantation, stent placement and other treatments were successfully performed endovascular repair.Conclusions:Pathway vascular disease can cause difficulties in endovascular treatment of abdominal aortic aneurysms. Endovascular repair can be successfully performed after corresponding treatments according to different difficulties, and the long-term patency rate is good.
