彩色多普勒血流显像诊断先天性冠状动脉瘘

Assessment of coronary artery fistula diagnosed by color Doppler flow imaging

目的 探讨彩色多普勒血流显像 (CDFI)诊断冠状动脉瘘的价值。方法 对 13例冠状动脉瘘患者行CDFI检查 ,年龄 8～ 68岁 ,仔细观察其起源、走行和引流部位。结果 13例冠状动脉瘘中 ,右冠状动脉瘘 8例 ,包括右冠状动脉 左室瘘 4例 ,右冠状动脉 肺动脉瘘 2例 ,右冠状动脉 右室瘘和右冠状动脉 右房瘘各 1例。左冠状动脉瘘 5例 ,包括左冠状动脉 肺动脉瘘 3例 ,左冠状动脉 右室瘘和左冠状动脉 右房瘘各 1例。CDFI均清楚显示 13例冠状动脉瘘的起源、走行和引流部位。 13例均经冠状动脉造影证实 ,其中 8例经手术证实。结论 CDFI诊断冠状动脉瘘简便、可行、准确 ,具有决定性的价值。

Objective To evaluate the value of color Doppler flow imaging(CDFI) in the diagnosis of congenital coronary artery fistula (CAF).Methods Thirteen consecutive patients ranging in age from 8 to 68 years underwent conventional transthoracic echocardiography,which depicts their origin, course, and drainage site. Results Right CAFs were detected in 8 patients: four of them had drainages to the left ventricle, two to the main pulmonary artery, one to the right ventricle(RV) and the other to the right atrium(RA). CAFs arising from the left coronary artery were noted in five patients: three of them had drainages to the main pulmonary, and the other two to the RA and RV respectively. The origin and the course were precisely defined and the drainage site was clearly depicted in all thinteen patients. The diagnosis of the thirteen patients was confirmed by coronary angiography, and eight of them received surgical treatment. Conclusions CDFI offers a simple, useful and reliable technique in diagnosis of CAF.
