Purpose:
The purpose of this study is to present an alternative technique for management of a type II endoleak associated with aneurysm sac enlargement.
Technique:
We report the use of a transseptal needle-sheath system for a transcatheter transcaval embolization (TTE) in a 3-staged treatment of a persistent type II endoleak after abdominal EVAR. Inferior vena cava is cannulated through a femoral venous access, and aneurysmal sac access is gained with a puncture through the walls of the 2 vessels at the site where the vein is adjacent to the aneurysm. The whole system (sheath-dilator-needle) is then advanced across the vascular walls into the aortic sac. Thus, embolization with glue is performed.
Conclusion:
The TTE using a transseptal needle-sheath system demonstrated to be feasible and effective to treat a persistent type II endoleak after failure of 2 attempts of transarterial embolization of the feeding vessels.
