冠状动脉分叉病变的介入治疗由于存在边支堵塞的风险在技术应用上受到限制。与非分叉病变相比,分叉病变的介入治疗有相对低的手术成功率、更大的手术花费和更高的再狭窄率。药物涂层支架的使用,使主支的再狭窄发生率有所下降,但边支开口的再狭窄和分叉病变长期预后中存在的再狭窄问题依然存在。在药物涂层支架时代,已出现双支架的治疗策略。通常根据分叉病变的不同类型采用不同的治疗技术,主支支架术加必要时边支支架术是目前通常采取的技术策略。
Interventional management of coronary bifurcation lesions is technically limited due to the risk of occlusion of the limbs. Interventional treatment of bifurcation lesions has a relatively lower success rate of surgery, greater surgical costs, and higher rates of restenosis compared to non-forbidden lesions. The use of drug-eluting stents has led to a decrease in the incidence of restenosis in the main branch, but there are still problems with restenosis in the long-term prognosis of stenosis and bifurcation of the branches. In the era of drug-eluting stents, a double stent strategy has emerged. Different treatment techniques are usually used depending on the type of bifurcation lesion, and the main stenting and, if necessary, stenting are the technical strategies commonly adopted so far.
