We describe a case of spontaneous coronary artery dissection that gave rise to post infarction unstable angina. An ambiguous angiographic appearance was shown by intracoronary ultrasound to arise from an extensive coronary dissection. The dissection membrane separating true and false lumina and features to suggest sluggish flow and early thrombosis in the false lumen were observed. No increase in lumen calibre was evident on ultrasound after PTCA (probably a consequence of the relatively large ultrasound catheter blank), but coronary flow reserve measured with intracoronary Doppler did improve and the patient remained stable and free of angina following the procedure.
我们描述了一例自发性冠状动脉夹层导致心肌梗死后不稳定型心绞痛的病例。冠状动脉内超声显示血管造影表现不明确是由广泛的冠状动脉夹层引起的。观察到分隔真腔和假腔的夹层膜以及提示假腔内血流缓慢和早期血栓形成的特征。PTCA术后超声检查未见管腔内径增加（可能是相对较大的超声导管空白的结果），但冠状动脉内多普勒测量的冠状动脉血流储备确实有所改善，术后患者保持稳定且未再发生心绞痛。
