冠状动脉支架置入术(Stenting)治疗直径大于3 mm的冠脉血管病变可明确降低再狭窄发生率,但对于小血管(直径3mm)的冠脉病变介入治疗方式仍有争论。本文旨在通过应用经皮冠状动脉腔内切割球囊成形术(Cutting Balloon Angiop las-ty,CBA)和普通球囊血管成形术(P lain O ld Balloo
Stenting of coronary stenting for coronary lesions greater than 3 mm in diameter can significantly reduce the incidence of restenosis, but there is still debate about the interventional modality of coronary artery disease in small vessels (3 mm in diameter). The purpose of this paper is to study the effect of percutaneous transluminal coronary angioplasty (PTCA) on percutaneous coronary angioplasty (PTCA) using Cutting Balloon Angioplasty (CBA) and Balloon Balloon
