Distal coronary perforation can cause early or late tamponade and is usually treated with fat or coil embolization. An alternative treatment strategy is occlusion of the ostium of the perforated vessel via implantation of a covered stent in the main vessel, which is typically achieved using the ping-pong guide catheter technique. In this technique, a balloon is inflated over one guide catheter to stop pericardial bleeding and a covered stent is delivered through a second guide catheter due to inability to fit both a balloon and a covered stent through a single guide catheter. With development of lower profile rapid exchange covered stents, a single guide catheter can be used to both occlude the target vessel and deliver the covered stent. We describe a case of distal vessel perforation in which a balloon was inflated to stop pericardial bleeding, followed by delivery of a covered stent (Graftmaster, Abbott Vascular) through a single 8-Fr guide catheter. This "block and deliver" technique represents a novel paradigm for treating coronary perforations through a single guide catheter, obviating the need for the ping-pong guide catheter technique. © 2017 Wiley Periodicals, Inc.
冠状动脉远端穿孔可导致早期或晚期心包填塞,通常采用脂肪或弹簧圈栓塞治疗。另一种治疗策略是通过在主血管中植入覆膜支架来闭塞穿孔血管的开口,这通常采用乒乓球导引导管技术来实现。在该技术中,在一根导引导管上充盈球囊以阻止心包出血,由于无法通过单根导引导管同时容纳球囊和覆膜支架,覆膜支架则通过第二根导引导管输送。随着更细的快速交换覆膜支架的发展,单根导引导管可用于闭塞目标血管并输送覆膜支架。我们描述了一例远端血管穿孔病例,其中先充盈球囊以阻止心包出血,随后通过一根8F单根导引导管输送覆膜支架(Graftmaster,雅培血管)。这种“封堵并输送”技术代表了一种通过单根导引导管治疗冠状动脉穿孔的新方法,无需使用乒乓球导引导管技术。© 2017威利期刊公司
