Stent underexpansion, a potential complication of percutaneous coronary intervention in severely calcified and stenotic coronary arteries, may result in in-stent thrombosis and restenosis. Different balloon-based and atheroablative techniques have been proposed to reduce the risk of these complications. We describe a simple triple-guidewire technique that we used to treat stent underexpansion in 2 elderly men.
支架扩张不足是经皮冠状动脉介入治疗严重钙化和狭窄冠状动脉的一种潜在并发症,可能导致支架内血栓形成和再狭窄。已经提出了不同的基于球囊和动脉粥样硬化消融技术来降低这些并发症的风险。我们描述了一种简单的三导丝技术,我们用该技术治疗了 2 例老年男性的支架扩张不足。
