用经皮冠脉腔内旋磨术(Pereutaneous Transluminal Coronary Rotational Ablation PTCRA)共4例属B和C型病变共9支血管13个损害进行旋磨治疗,12个达到早期成功标准,其中例1和例4为LAD和D1分叉严重狭窄,例2和例3RCA距开口1cm处严重狭窄,例3RCA中段狭窄波及锐缘支开口,例4为多支多处复合性损害。术中例1可能发生LAD损伤和轻度心包填塞,经保中治疗后痊愈。例3术后早期LAD急性闭塞,经溶栓后复通,无进展为急性心肌梗塞。闭塞原因可能系肝素用量不足。 治疗结果显示PTCRA可作为PTCA的补充,尤其适用于复杂和操作难度大的病变的治疗和挽救PTCA后急性血管闭塞的病人。
A total of 4 lesions of type B and C were treated by rotational atherectomy with 12 lesions in 9 patients with Pereutaneous Transluminal Coronary Rotational Ablation (PTCRA). Twelve of them reached the early success criteria. Cases 1 and 2 Example 4 for the LAD and D1 bifurcation severe stenosis, cases 2 and 3RCA severely stented from the opening 1cm, 3RCA stenosis in the middle of the sharp edge of the opening, Example 4 is multiple and multiple complex damage. Intraoperative case 1 may occur LAD injury and mild tamponade, after treatment, heal. Example 3 acute occlusion of early postoperative LAD, after thrombolysis recanalization, no progress to acute myocardial infarction. The cause of occlusion may be due to insufficient heparin. Treatment results show that PTCRA can be used as a supplement to PTCA, especially for complex and difficult to treat the disease and save the patients with acute vascular occlusion after PTCA.
