摘要
目的 评估逆向介入治疗冠状动脉慢性完全闭塞合并钙化病变的有效性和安全性.方法 4例冠状动脉慢性完全闭塞合并钙化病变,3例右冠,1例前降支病变；4例闭塞处均有分支,2例明显迂曲,1例为前降支开口病变；在150 cm Finecross微导管的支持下,4例全部采用逆向导丝技术,其中3例直接选用逆向介入治疗,1例正向失败后选用逆向方法.结果 4例逆向导丝均通过侧支循环送到闭塞病变远端,1例通过左回旋支至右冠的心外膜下侧支,3例通过间隔支；2例采用反向CART技术,随后逆向导丝体外化；1例使用正逆向微导管对吻钢丝技术,即正逆向微导管在正向指引导管对吻后,正向导丝经逆向微导管通过左前降支闭塞病变；1例逆向及正向导丝均未能通过严重钙化和迂曲的右冠闭塞病变,未能开通闭塞血管.手术成功率75％,3例开通血管均植入药物洗脱支架.4例术中及住院期间未发生并发症.结论 逆向介入治疗冠状动脉慢性完全闭塞合并钙化病变是有效和安全的.
Objective To evaluate the efficacy and safety of retrograde wire in chronic total occlusion with calcification.Methods 4 patients with chronic total occlusion with calcification were selected.3 RCA and 1 LAD as CTO target vessel.Side branches proximal to the occlusion waspresent in all patients,2 of 4 with extreme tortuosity,1 of 4 with ostial occlusion in LAD.At the support of 150cm Finecross microcatheter,all patients were treated with the retrograde technique,with 3 of 4 as primary strategy,1 of 4 as immediately after antegrade failure.Results Retrograde wire crossed the collaterals and successfully delivered distal to the occlusion in all patients.Epicardial collateral from LCX to RCA was accessed in 1 patient,and septal in 3 of 4 patients.Reverse CART technique was applied in 2 of 4 patients,and subsequent exteriorization of the retrograde wire via the antegrade guide was completed.Kissing of antegrade and retrograde microcatheters inside antegrade guide was completed and antegrade wire crossed the CTO lesion via retrograde microcatheter in 1 patient.Both retrograde and antegrade wires could not cross the CTO lesion in 1 patient with extreme tortuosity and severe calcification,and the RCA CTO lesion was not opened in this patient.Overall successful rate was 75％.Drug eluting stents were implanted in 3 successfully recanalized vessels.All patients had no complications during procedure and subsequent hospitalization.Conclusion The retrograde approach was used with high degree of success and safety in chronic total occlusion with calcification.
