Off Label Use of StarClose for Superior Gluteal Artery Puncture Closure Following Embolisation of an Internal Iliac Artery Type II Endoleak.

Introduction: Embolisation of type II internal iliac artery endoleaks is challenging given limited options for obtaining transarterial access and for achieving access site haemostasis.

Report: An 86 year old woman who had undergone endovascular repair for an aorto-iliac aneurysm was found to have serial enlargement of the left common iliac artery portion of the aneurysm observed over a period of two years. At the time of the initial repair, the left internal iliac artery was embolised using coils, and then was covered by extending the iliac limb endoprosthesis into the external iliac artery. However, computed tomography angiography showed recanalisation of the previously coiled left internal iliac artery, thus allowing contrast to flow into the left common iliac aneurysm sac. Given that the internal iliac artery origin was covered and there was no visible collateral pathway, direct puncture of the superior gluteal artery was selected to access the left internal iliac artery in a retrograde fashion. This presented a challenge in terms of achieving haemostasis given the deep position of the arterial access site, which was unlikely to be amenable to manual compression. Off label StarClose was chosen for closure of the superior gluteal arterial access, with successful haemostasis and preserved patency of the vessel.

Discussion: Off label StarClose was used successfully to obtain haemostasis after obtaining percutaneous transgluteal access to the superior gluteal artery in order to embolise a type II endoleak arising from the internal iliac artery.
