Abstract
Background: Exploring the effectiveness and safety of n-butyl-2-cyanoacrylate (NBCA) in the transarterial embolization for common endoleak during and after endovascular repair of aortic aneurysm (EVAR).
Methods: A total of 226 patients with abdominal aortic aneurysm (AAA) were treated with EVAR in 4 years from August 2019 to February 2023, including 46 patients with ruptured aneurysms (rAAA). 37 cases, 28 nonruptured AAA patients and 9 rAAA patients, developed endoleak during EVAR surgery and follow-up period and were then treated with NBCA for transarterial embolization. A follow-up was done for at least 6 months to observe its clinical efficacy and adverse reactions.
Results: Among 37 cases of endoleak, there were 8 cases of primary type Ia endoleak and one case of primary right type Ib endoleak in the rAAA group, one case of primary type Ib endoleak, 2 cases of secondary type Ia endoleak, and 25 cases of postoperative type II endoleak in the nonruptured AAA group. Three patients with primary type Ia endoleak were treated with coil-assisted NBCA in the rAAA group, while the remaining 34 patients with type I and type II endoleaks were treated with NBCA alone. All transarterial embolization achieved technical success, and the endoleak disappeared. Postoperative hospitalization observation showed that 3 cases of patients in the rAAA group who experienced primary type Ia endoleak during emergency EVAR surgery died within 4 days after surgery due to hemorrhagic shock and multiple organ failure. Two patients experienced non-AAA-related deaths during the follow-up period.
Conclusions: Transarterial embolization with NBCA for the treatment of primary and secondary endoleak is a safe and effective method. It can achieve more dense embolization of the aneurysm sac and more complex endoleaks embolization. And, it showed a low recurrence rate of endoleak and the incidence of perioperative complications after surgery, which is worthy of clinical promotion and application. Even in emergency EVAR combined with primary type I endoleak treatment in rAAA patients, patients can still benefit.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
