Although PTCA balloon technology has improved dramatically since the first catheters were introduced over a decade ago, some limitations remain. The largest conventional balloon size available is 4.0 mm diameter. Larger size balloons are sometimes necessary for saphenous vein graft dilatation or in very large native coronary arteries. Also, adjunctive balloon angioplasty is used frequently after atherectomy and other coronary device therapy. Current generation balloons are not always necessary in this setting, since a large lumen has already been established. Thus, it has become useful in our laboratory to use peripheral arterial angioplasty balloons for both large coronary vessel dilatation, and also for adjunctive dilatation after device use. We describe our initial experience with peripheral arterial angioplasty balloons as adjuncts to percutaneous coronary revascularization.
尽管自十多年前首次引入导管以来，经皮冠状动脉腔内血管成形术（PTCA）球囊技术有了显著改进，但仍存在一些局限性。目前可用的最大常规球囊尺寸为直径4.0毫米。对于隐静脉移植血管扩张或非常粗大的自身冠状动脉，有时需要更大尺寸的球囊。此外，在旋切术和其他冠状动脉器械治疗后，常使用辅助球囊血管成形术。在这种情况下，新一代球囊并不总是必需的，因为已经建立了较大的管腔。因此，在我们实验室中，使用外周动脉血管成形术球囊进行粗大冠状动脉血管扩张以及器械使用后的辅助扩张已变得很有用。我们描述了将外周动脉血管成形术球囊作为经皮冠状动脉血运重建辅助手段的初步经验。
