title: [The importance of investigating the internal thoracic artery before coronary artery surgery in Leriche's syndrome].
abstract: Frequently, both peripheral and coronary artery disease are present in the same patient. In patients with abdominal aortic occlusion (i.e., Leriche's syndrome) or femoroiliac occlusion, collateral circulation to the lower extremities can originate in branches of the abdominal aorta or even in the internal thoracic artery (depending on the level of the occlusion). It is important to identify the origin of this circulation during diagnostic procedures, especially in patients who may need to undergo coronary revascularization surgery since, in cases where the majority of the collateral circulation originates in the internal thoracic artery, using the artery as a coronary graft could lead to acute ischemia of the lower extremities. We present three patients with Leriche's syndrome in whom the internal thoracic artery was the origin of the collateral circulation to the ipsilateral femoral artery.
