Prevention of Type II Endoleak Using Postoperative Coiling of the Abdominal Aortic Aneurysm Sac during Stent Graft Implantation
Abstract
Aim: A prospective randomized study assessing the success rates of type II endoleak (EL) prevention, using postoperative coiling of the abdominal aortic aneurysm (AAA) sac during stent graft (SG) implantation. Results: Prior to the procedure, there were only minor differencies in the number of source type II EL arteries (AL 3.8 vs. 3.5; AMI 0.78 vs. 0.55; ASM 0.26 vs. 0.3; ARA 0.095 vs. 0.05), preoperative AAA sac size (68.6 vs. 67.0 mm) and the lumen size (47.6 vs. 40.0 mm), the AAA sac size at the end of the studied period (63.9 vs. 62.1 mm) and its mean size change (-4.7 vs. -4.9 mm), between the Group A and B, respectively.
Postoperatively, the type II EL was detected in 6 subjects in Group A (14.3%), and in 9 subjects in Group B (20.5%). At the study endpoint, the type II EL was identified in 4 subjects in Group A (9.5%), in 8 subjects in Group B (18.2%).
Conclusion: Peroperative introduction of coils into the AAA sac is one of the options for type II EL prevention.
