Abstract:
Objectives:To investigate the safety and efficacy of Cuffstent in the treatment of immediate type Ia endoleak during endovascular aneurysm repair(EVAR)of abdominal aortic aneurysm.Methods:The clinical data of 24 patients with immediate type Ia endoleak during EVAR treated with Cuffstent at the Second Xiangya Hospital of Central South University from January 2019 to December 2022 were retrospectively analyzed.There were 18 males and 6 females with a mean age of(70.3±7.1)years.Results:Of the 24 patients,22 underwent conventional proximal Cuffstent implantation,and 2 underwent fenestrated Cuffstent to preserve unilateral renal artery.Emergency EVAR was performed in 7 patients.The procedure was technically successful in all patients.Immediate disappearance of type Ia endoleak was achieved in 23 patients,whereas 1 patient exhibited mild persistent type Ia endoleak,which was managed conservatively with watchful follow-up.All the 24 patients finished an average of(39.0±15.1)months follow-up,and all patients were alive during the follow-up period.Two patients received aortic reintervention,and one patient received thoracic aortic stent graft implantation due to thoracic aortic penetrating ulcer,and one patient received abdominal aortic aneurysm resection and iliac artery stent implantation due to type II endoleak and iliac artery rupture,respectively.There were no other aorta-related complications and reintervention.Conclusions:Proximal addition of Cuffstent for the management of immediate type Ia endoleak during EVAR is safe and effective.
