Percutanous transluminal coronary angioplasty (PTCA) was performed in 190 patients with 250 diseased vessels and 278 lesions from Dec. 1987 to Feb. 1994. All the patients had unstable angina (UA). There were 52 (18.7%) type A lesions, 175 (62.9%) type B lesions and 51 (18.3%) type C lesions. Of the 190 patients undergoing PTCA, 134 (70.5%) patients had dilatation of a single vessel, 46 (24.2%) of two vessels and 10 (5.3%) of three or more vessels. In 121 patients with multivessel disease, 98 (81.0%) had incomplete revascularization of the ischemia-related vessel (the culprit vessel) and only 23 (19.0%) had complete vessel revascularization. Kissing balloon technique was used in six patients and autoperfusion balloon in five. There were four patients undergoing directional coronary atherectomy (DCA) and four intracoronary stent. The clinical (patient) success rate was 94.7% (180/190) and technical (vessel) success rate 95.2% (238/250). The average degree of vessel stenosis was 88.7% +/- 8.3% before PTCA and the residual tenosis was 17.9% +/- 9.2% after PTCA. Acute vascular complications occurred in 18 (6.5%) lesions. 15 were managed successfully, two developed Q wave myocardial infarct and one died. None needed emergency coronary bypass operation. PTCA was not successful in 10 patients. In 180 patients with successful PTCA, 165 (91.7%) were free from UA, 15 (8.3%) patients had symptoms improved and oxygen need reduced. During a six-month follow-up, 26 patients had chest pain again with confirmed restenosis, repeated PTCA was performed successfully.
1987年12月至1994年2月，对190例患者的250条病变血管和278处病变进行了经皮腔内冠状动脉成形术（PTCA）。所有患者均患有不稳定型心绞痛（UA）。其中A型病变52处（18.7%），B型病变175处（62.9%），C型病变51处（18.3%）。在接受PTCA的190例患者中，134例（70.5%）患者扩张了单支血管，46例（24.2%）扩张了两支血管，10例（5.3%）扩张了三支或更多支血管。在121例多支血管病变患者中，98例（81.0%）对缺血相关血管（罪犯血管）的血运重建不完全，只有23例（19.0%）实现了完全血管血运重建。6例患者采用了亲吻球囊技术，5例采用了自灌注球囊。4例患者接受了定向冠状动脉斑块旋切术（DCA），4例植入了冠状动脉内支架。临床（患者）成功率为94.7%（180/190），技术（血管）成功率为95.2%（238/250）。PTCA术前血管平均狭窄程度为88.7%±8.3%，术后残余狭窄为17.9%±9.2%。18处（6.5%）病变发生了急性血管并发症。15例成功处理，2例发生Q波心肌梗死，1例死亡。无一例需要急诊冠状动脉搭桥手术。10例患者PTCA未成功。在180例PTCA成功的患者中，165例（91.7%）无UA症状，15例（8.3%）患者症状改善，需氧量减少。在6个月的随访期间，26例患者再次出现胸痛，经证实为再狭窄，成功进行了重复PTCA。
