Type Ic Endoleak after LifeStream Balloon-Expandable Stent Graft and Zenith Iliac Branch Device Placement

Vasc Specialist Int. 2023 Mar 6:39:2. doi: 10.5758/vsi.230002.


Considering the recent advancements in endovascular management of aortoiliac aneurysms, the use of an iliac branch device (IBD) to preserve pelvic blood flow and reduce complications caused by embolization of the internal iliac artery (IIA) is recommended by various guidelines. Although the outcomes reported following IBD placement are mainly positive and durable, IBD-specific complications such as a type Ic endoleak and associated reintervention may occur. Moreover, only one IBD device and one type of balloon-expandable bridging stent graft for IIA are currently available on the domestic market. Here we present two cases of type Ic endoleak following IBD placement. In both cases, IIA diameter was slightly larger than the basic instructions for use. Notably, the initial procedures were considered successful; however, type Ic endoleaks were detected on 1-month follow-up imaging. This finding emphasizes the need for a precise preoperative evaluation, intraoperative manipulation, and postoperative follow-up.
