EXPERIENCE OF TREATMENT OF INFRARENAL ABDOMINAL AORTIC ANEURYSM WITH HOSTILE NECKS BY ENDOVASCULAR INTERVENTION AT CHO RAY HOSPITAL
Main Article Content
Abstract
Introduction: Treatment of abdominal aortic aneurysms with hostile necks remains a challenge. Currently, few studies have evaluated the results of treatment of infrarenal abdominal aortic aneurysms with hostile necks. Objective: Evaluation of perioperative and mid-term outcomes of endovascular intervention for infrarenal abdominal aortic aneurysm with hostile necks. Patients and methods: A retrospective descriptive case series was conducted from May 2012 to August 2023 at the Vascular Surgery Department of Cho Ray Hospital. Results: There were 92 patients with abdominal aortic aneurysms treated with unfavorable neck who met the criteria for inclusion in the study. The mean age of the study was 73.8 ± 7.2 years, with a male predominance (male/female = 3.4/1). The technical success rate was high at 91,3%. The early mortality rate was low at 1,1%. The complication rate was low, with no cardiovascular or respiratory events recorded during the perioperative period. Renal failure complications were recorded at 7.6%, especially in cases with additional chimney procedures. Early endoleak was low at 7,6%. All were re-intervened by endovascular intervention. Late type I endoleak 7.5%. The mid-term mortality rate was 10,9%. Conclusion: Endovascular intervention for infrarenal abdominal aortic aneurysms can be performed safely and effectively in patients with hostile neck, with a high technical success rate.
