Abstract:
Objective To investigate the management experience of type Ⅱ endoleak originating from inferior mesenteric artery (IMA) after endovascular abdominal aortic aneurysm repair (EVAR). Methods The clinical data of patients with type Ⅱ endoleak originating from IMA after EVAR treated in the Department of Vascular Surgery, Shandong Provincial Hospital Affiliated to Shandong First Medical University from October 2016 to November 2021 were collected and analyzed. Results There were 12 males and 3 females at age of 57-89 (68.00±7.84) years. Eleven patients received embolization of the abdominal aortic aneurysm lumen and initial segment of the IMA via the superior mesenteric artery-middle colic artery-Riolan arch-left colic artery-IMA route. Three patients received embolization of the initial segment of the IMA by the above route. One patient underwent open dissection of the abdominal aortic aneurysm, and orifice of IMA was sutured in the aneurysm cavity while stents were retained. All 15 patients were successfully treated by surgery. The symptoms of back pain, abdominal pain and abdominal distension disappeared in 6 patients after surgery. Neither perioperative deaths nor complications happened during the treatment and follow-up period. The median follow-up time was 11.00 (9.00, 18.00) months. Two patients with typeⅡendoleak recurred during the follow-up period and were admitted to hospital for secondary embolization. No recurrence was observed at 12 months postoperative follow-up. Conclusion Type Ⅱ endoleak is one of the most common complications after EVAR. IMA is the most common criminal origin of typeⅡendoleak. TypeⅡendoleak that lead to persistent expansion of the aneurysm cavity requires aggressive intervention.
