The clinic experience of coronary stent in small vessel / 中国介入心脏病学杂志

ABSTRACT

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
