Ruptured abdominal aortic aneurysm treated using infrarenal-occlusion-balloon technique with ENDURANT IIs

Abstract

Rapid and effective cessation of bleeding is the most important step in the treatment of ruptured abdominal aortic aneurysms (rAAAs) and should be achieved before endovascular abdominal aneurysm repair (EVAR). In this study, we assessed the infrarenal-occlusion-balloon technique using ENDURANT Ⅱs for rAAAs. Our technique involves dilating the occlusion balloon in ENDURANT Ⅱs just below the renal artery, which helps avoid damage to the native aorta and the risk of organ ischemia. Additionally, the ability to perform continuous EVAR with bleeding control is another major advantage. We analyzed 12 consecutive patients with rAAAs who were treated using our infrarenal-occlusion-balloon technique with ENDURANT Ⅱs between March 2016 and December 2024. The average time from the start of surgery until hemostasis was 20 min, with a 30-day mortality rate of 16.7 %. Our infrarenal-occlusion-balloon technique using ENDURANT Ⅱs can be considered a faster, safer, and more effective method for treating rAAAs.
