Abstract

We describe two cases of left atrial myxoma, demonstrating an unusual tumor vascularity as revealed by coronary angiograms. Both cases had suffered typical episodes of transient ischemic attack (TIA). Coronary angiography revealed tumor blood supply from coronary arteries in both cases, and also a leakage of contrast medium from the surface of the tumor blood vessels to the left atrium in one case. In the medical literature available in English reviewed so far, no report of such a leakage has been reported. Selective coronary arteriography can be a useful diagnostic method of delineating left atrial myxoma and its blood supply.

摘要

我们描述了两例左心房黏液瘤病例，冠状动脉造影显示出不同寻常的肿瘤血管情况。两例患者均有典型的短暂性脑缺血发作（TIA）病史。冠状动脉造影显示，两例病例的肿瘤血供均来自冠状动脉，其中一例还出现了造影剂从肿瘤血管表面渗漏至左心房的情况。在目前所查阅的英文医学文献中，尚无此类渗漏情况的报道。选择性冠状动脉造影可作为一种有用的诊断方法，用于明确左心房黏液瘤及其血供情况。
