Abstract
Aneurysms of the left main coronary artery are exceedingly rare clinical entities, encountered incidentally in approximately 0.1% of patients who undergo routine angiography. Thrombosis within the aneurysm can lead to distal embolization and myocardial infarction. These lesions can extend into adjacent coronary branches and can occur in the presence or absence of obstructive coronary disease. Depending on the severity of coexistent coronary stenoses, patients with left main coronary artery aneurysms can be effectively managed either operatively or medically. We report the cases of 2 patients who were treated medically for large left main coronary aneurysms and concomitant right coronary artery ectasia.
摘要
左冠状动脉主干动脉瘤是极为罕见的临床病症，在接受常规血管造影的患者中约0.1%偶然发现。动脉瘤内的血栓形成可导致远端栓塞和心肌梗死。这些病变可延伸至相邻的冠状动脉分支，可在有或无阻塞性冠状动脉疾病的情况下发生。根据并存冠状动脉狭窄的严重程度，左冠状动脉主干动脉瘤患者可通过手术或药物进行有效治疗。我们报告2例因左冠状动脉主干大动脉瘤合并右冠状动脉扩张而接受药物治疗的病例。
