Aneurysms of the internal mammary artery are extremely rare. Immediate treatment is necessary because of the high risk of rupture that can be life-threatening. Here we describe a case of idiopathic internal mammary artery aneurysm in a 54-year-old woman in the setting of aberrant right subclavian artery. The aneurysm was successfully treated with coil embolization without complications.

Therapy for large symptomatic keloids is often plagued with complicated reconstruction manner and recurrence. This article reports a rare treatment combination for a chest keloid with internal mammary artery perforator flap reconstruction and radiation therapy. We excised the keloid and covered the defect with an internal mammary artery perforator flap. Immediate electron-beam irradiation thera...

BACKGROUND Proliferation of the intima is an early lesion of saphenous vein graft disease. Early patency rates of radial artery grafts are acceptable, but little is known about their risk of intimal hyperplasia. METHODS AND RESULTS To develop a model of intimal hyperplasia, we incubated human saphenous veins, internal mammary arteries, and radial arteries (n=6, 8, and 10, respectively) in an ...

The left internal mammary artery is commonly used during coronary artery bypass grafting to provide direct revascularization for arteries, typically left anterior descending artery, with significant coronary atherosclerosis. In the world medical literature, we identified only 3 cases of well-documented anomalous origin of the left internal mammary artery from the aortic arch identified followin...

internal mammary grafts, and prosthetic tube grafts. The results with all these are either dismal or unknown. One other option is the use of the free internal mammary artery. This method extends the range of the grafts and gives results with an enhanced long term patency similar to those with pedicled internal mammary artery grafts,'3 but it imposes a technically awkward requirement for a proxi...

The deep inferior epigastric perforator flap has become increasingly popular for breast reconstruction with the most common recipient vessels being the internal mammary artery and vein. In certain cases, however, these recipient vessels are inadequate due to an absent or diminutive vein. Moreover, patients at high risk for future coronary artery disease may sacrifice the best conduit for corona...

Little is known regarding specific biologic and pharmacologic differences between human internal mammary arteries and saphenous veins. To better define the role of alpha-adrenoceptor-mediated vasoconstriction in human internal mammary arteries and saphenous veins, we obtained fresh specimens of both vessels from 32 patients undergoing coronary artery bypass surgery. Dose-response curves were ge...
