中远端冠脉病变的支架治疗

目的 :评价应用具有磷酸胆碱涂层的小血管支架治疗中远端细小冠脉的病变 (≤ 2 5mm)的疗效。方法 :选择 60例冠心病患者 ,年龄 5 4 2± 10 5岁。男 4 6例 ,女 14例 ,常规行冠状动脉造影 ,对病变血管以美国GE公司血管造影机测量系统实时测量病变血管直径 ,<2 5mm病变血管共 69支 ,平均血管直径 2 0± 0 4 5mm ,植入BiodivYsioSV支架 74个。结果 :69支病变血管均经球囊扩张后植入支架 ,手术成功率 10 0 %。支架植入后病变平均狭窄直径减至 0 %～ 10 % ,无 1例急性 亚急性支架内血栓形成。全部病例随访 6± 3 8个月 ,无 1例死亡。 15例于术后 4± 1 2个月心绞痛复发 ,经冠脉造影证实13例为支架内再狭窄 ,2例出现新部位血管病变。结论 :应用具有磷酸胆碱涂层支架治疗小血管病变 ,再狭窄率低 ,临床疗效肯定

Stenting in small coronary artery disease

Objective:To evaluate the clinical effectiveness of treating small coronary artery disease with phosphorylcholine(PC) coated stent.Method:Sixty|nine diseased small vessels with a reference diameter≤2^5 mm(average 2^0±0^45 mm) were found in 60 patients(age 54 2±10^5 years,46 male and 14 female) during coronary angiography and 74 Biodiv Ysio SV stents were implanted.Result:All stents were implanted successfully after predilation.The residual stenosis of the diseased vessels after stenting were 0%～10%.No acute or subacute stent thrombosis was found.During the 6±3^8 months follow|up,15 patients were found recurrent angina in 4±1^2 months after stenting.Angiography demonstrated 13 patients (17 6%) had in|stent restenosis and 2 cases got new lesions.Conclusion:PC coated stent is effective in the treatment of small vessel disease and also decreases the in|stent restenosis.
