Beta-adrenoceptor-mediated responsiveness of human internal mammary artery
The internal mammary artery (IMA) is currently the preferred conduit for myocardial revascularization. However, pre-operative vasospasm and a hypoperfusion state during maximal exercise may limit its use as a bypass graft. The mechanism of spasm has not been clearly defined. Since β-adrenoceptor activation plays a major role in vasorelaxation, the present study was carried out to investigate th...
متن کاملIdiopathic internal mammary artery aneurysm
Aneurysms of the internal mammary artery are extremely rare, and their presentation and treatment are variable. Since these aneurysms often tend to rupture and cause haemothorax and life-threatening conditions, the knowledge of secure treatment options is indispensable. We here report the case of an idiopathic internal mammary aneurysm in a 46-year-old man. Open surgical resection of the aneury...

متن کاملManagement of Internal Mammary Artery Spasm
The article is dedicated to the management of internal mammary artery spasm intraand postoperatively based on the accumulated evidence in the literature. It provides stepwise decision algorithms for safely resolving the spasm and prevention of relapse. INTRODUCTION The left internal mammary artery (IMA) is the most widely used graft and is predominantly anastomosed to the left anterior descendi...
متن کاملInternal mammary artery graft false aneurysm.
A 59-year-old male patient presented with a pulsating mass at the left sternal edge weeks after a CABG procedure. CTshowed a false aneurysm of the LIMA (Fig. 1), confirmed by angiography (Fig. 2a). The leakage was treated using a 16-by-3.5-mm Jostent leading to complete lesion thrombosis (Fig. 2b). Fig. 1. Contrast enhanced CT shows a 6 cm diameter left internal mammary artery false aneurysm. F...
