Treatment of iatrogenic aortic dissection by percutaneous stent placement

During elective cardiac catheterization via the right femoral artery, difficulty was encountered advancing the guidewire beyond the aortic arch and the procedure abandoned. The patient later developed back pain and hypotension. A contrast-enhanced spiral computed tomography scan confirmed aortic dissection, extending from an entry point in the external iliac artery to the arch. We hypothesized that the entry site was responsible for filling the dissection in the thoraco-abdominal component. A stent was placed in the iliac artery, occluding the entry point. This is the first report of aortic dissection, a rare complication of angiography, managed by percutaneous stenting of the entry point.
