摘　　要：目的　在直径小于 3mm的冠状动脉分别进行PTCA和支架术 ,观察其急性并发症和近期疗效。方法　 42例患者 ,5 2支血管 ,血管直径小于 3mm ,随机选择单纯PTCA或支架术。测量术前和术后参考血管直径、直径狭窄程度和最小管腔直径 ,并观察术后 30天内急性闭塞、亚急性血栓形成、Q波或非Q波心肌梗塞、急诊冠脉搭桥和死亡发生情况。结果　支架组选用更大的球囊和更高的充盈压力 ,术后获得较大的管腔直径 ,残余狭窄程度显著低于PTCA组。支架组出现 1例亚急性血栓形成 ,PTCA组出现 1例急性闭塞。两组均无Q波或非Q波心肌梗塞、冠脉搭桥和死亡发生。结论　对于直径小于 3mm的冠状动脉应该在PTCA基础上 ,选择性地植入支架 。Objective To compare the acute complication and short term effect between angioplasty and stent in coronary arteries less than 3 mm Methods There were forty two patients and fifty two vessels attending to the study During procedure, native vessel diameter, stenosis degree and MLD were measured pre operation and post operation, and the clinic features of acute occlusion, subacute thrombosis, acute MI, emergent CABG and death were followed within thirty days after operation Results Stent group showed larger balloon, higher pressure during balloon dilatation, larger vessel lumen and lower residue stenosis than balloon group There were no acute MI, emergent CABG and death in two groups, but one subacute thrombosis in stent group and one acute occlusion in balloon group Conclusion Selective stent in small vessel may reduce acute complication and restenosis after interventional therapy
