Aberrant left internal thoracic artery origin from the extrascalenic part of the subclavian artery.

The internal thoracic artery (ITA) is considered to be the optimal conduit for surgical coronary artery revascularization. Variations in ITA anatomy are relatively common and may impact surgical results. The ITA usually arises from the intrascalenic (first) part of the subclavian artery (SCA) and, occasionally, from the interscalenic (second) part.

Combined endovascular/surgical management of a ruptured para-anastomotic aneurysm of the left common iliac artery.

A 75-year old man presented with signs and symptoms of acute abdomen and a clinical picture of hypovolemic shock. An emergency CT scan revealed a ruptured para-anastomotic left common iliac artery aneurysm. The patient had undergone an elective abdominal aortic aneurysm repair operation and placement of an aortoiliac bifurcated graft 10 years before.
