【摘要】 目的探讨应用经皮冠状动脉腔内成形术（ＰＴＣＡ）治疗复杂冠状动脉病变的效果。方法５例冠心病患者经选择性冠状动脉造影证实为复杂冠状动脉病变即Ｂ型或Ｃ型病变者，采用Ｇｒｕｅｎｔｚｉｇ等建立的方法进行ＰＴＣＡ。结果１２处冠状动脉病变扩张成功１０处，成功率为８３．３％，其余两处病变一处因球囊未能通过狭窄部，另一处因术中患者发生严重的心律失常而未行扩张。术后患者的症状均得以缓解或消失。结论ＰＴＣＡ也适用于治疗复杂冠状动脉病变，且疗效较好，但危险性较大，并发症较多。更多还原

【Abstract】 Objective To research the effect of percutaneous transluminal coronary angioplasty (PTCA) on treating complicated artery lesions.Methods Type B or type C of complicated coronary artery lesions were confirmed by selective coronary angiography in 5 cases with coronary heart disease. Gruentzig’s method was used in carring out PTCA.Results Ten of twelve parts of coronary artery lesions were dilated successfully, the success rate was 83.3% .In failed two parts of PTCA, one was because of the balloon failed to pass the narrow artery through, the other one was unable to be performed for the occurrenced severe arrthymia during the procedure. Symptoms of all case were improved or disappeared after PTCA.Conclusion PTCA is also fit in treating complicated coronary artery lesions and has a better therapeutic effect, but it has more complications and run more risks relatively.更多还原
