冠状动脉成形术(PTCA)因创伤较少同时费用节省而日益盛行,但既往所做的PTCA主要是在单支血管近端阻塞的患者,其成功率10%,死亡率7%,近来许多中心成功率达90%,然大多数有症状的患者有多支血管病变,其中多数做了旁路手术.因而PTCA对临床的真正影响最后可能取决于此术能否运用于多支冠状动脉病变患者.本文对多支血管病变患者中PTCA的作用与冠状动脉旁路手术的结果进行回顾性非随机比较.
Coronary angioplasty (PTCA) is increasingly prevalent due to less trauma and cost savings, but previous PTCAs were primarily targeted at patients with proximal occlusion of the single vessel with a 10% success rate and a 7% mortality rate. Many recent centers The success rate is 90%, but most symptomatic patients have multivessel disease, most of whom have undergone bypass surgery.The true clinical impact of PTCA may ultimately depend on whether the technique can be used in patients with multivessel coronary artery disease In this review, the effect of PTCA in patients with multivessel disease and the results of coronary artery bypass surgery were compared retrospectively and nonrandomly.
