We describe treatment of six chronic total occlusions due to in-stent restenosis with the CrossBoss catheter (BridgePoint Medical, Minneapolis, Minnesota). The CrossBoss catheter allowed successful CTO crossing in 5 of 6 lesions (83%): in 50% the catheter entered the distal true lumen, whereas in 33% a wire was required for distal true lumen crossing. No complications were observed. Use of the CrossBoss catheter can facilitate treatment of coronary chronic total occlusions due to in-stent restenosis.
我们描述了使用 CrossBoss 导管（BridgePoint Medical，明尼苏达州明尼阿波利斯）治疗 6 例因支架内再狭窄导致的慢性完全闭塞。在 6 例病变中，CrossBoss 导管成功实现了 5 例（83%）的 CTO 穿越：导管进入远端真腔的比例为 50%，而在 33%的病例中需要使用导丝进行远端真腔穿越。未观察到任何并发症。使用 CrossBoss 导管可以促进治疗因支架内再狭窄导致的冠状动脉慢性完全闭塞。
