Endovascular treatment of spontaneous isolated common and external iliac artery dissections with preservation of pelvic blood flow.

Spontaneous isolated dissection of iliac arteries is very rare, with few reports in the literature. Medical, surgical, and endovascular treatment modalities have all been used to manage iliac artery dissections. We report a case of symptomatic, isolated, spontaneous dissection of the common iliac and external iliac arteries. Both dissections were successfully treated by separate percutaneous stent-graft placement, preserving hypogastric artery flow. This technique is interesting because it provides adequate sealing of proximal and distal dissection sites while preserving hypogastric artery and pelvic flow.
