摘要
目的 评价双钢丝球囊在支架内再狭窄治疗中的有效性和安全性。方法 32例支架内再狭窄病人, 共有再狭窄靶病变37处,采用双钢丝球囊对靶病变进行扩张,观察扩张效果并进行临床随访。结果 全部37 处再狭窄病变的双钢丝球囊扩张成功率为100％,术后血管狭窄程度明显减轻[(87.7±8.6)％比(7.7±6.7)％, P<0.001],住院期间无1例发生死亡、未发生Q波性心肌梗死和心力衰竭等严重临床并发症。1处支架外缘受 累的再狭窄病变在扩张后出现轻度内膜撕裂(A型),4处支架外缘受累的再狭窄病变于支架外缘受累血管段补 充置入支架。临床随访3-15(8.0±3.4)个月,2例出现心绞痛复发。结论 双钢丝球囊成形术对支架内再狭 窄是有效、安全的治疗方法。
Purpose To assess the efficiency and safety of dual-wire balloon angioplasty in the treatment of coronary in-stent restenosis. Methods This study included thirty-two patients with coronary in-stent restenosis. Selective dual-wire balloon angioplasty was performed in 37 target in-stent restenoses. Results Success rate of dilatation was 100 % . The severity of stenosis was significantly less than that of pre-opera-tion [(87.7+8.6)%vs(7.7+6.7)%,P<0.001] without severe complications.Slight dissection (type A) proximal to the previous stent occurred in one case whose restenotic lesion involving the segment proximal to the stent. Adjunctive stenting was performed in 4 restenotic lesions involving proximal or distal coronary segments. Angina pectoris recurred in 2 patients during the 3-15 months follow-up period. Conclusions Dual-wire balloon angioplasty is effective and safe for the treatment of in-stent restenosis.
