A new family of four guiding catheters (8 French and 9 French) has been developed for angioplasty of aortocoronary vein grafts and native coronary arteries beyond vein graft insertions. In 67 consecutive grafts and native vessels dilated through the grafts in 54 patients, the procedural success rate was 97%. The G-1 standard catheter was employed for the majority of the procedures (66%), but the G-3 catheter was better for high anterior grafts and the G-4 catheter was better for high left grafts. The G-2 catheter was better for lower right grafts, especially in dilated aortas. Balloon angioplasty alone using 8 French catheters was performed in 60 procedures, and excimer laser with adjunctive balloon angioplasty using 9 French catheters was performed in 7 procedures. These unique guiding catheters provide an attractive alternative to existing vein graft guides by their improved seating and backup support. They may be the primary choice for vein graft angioplasty and may have future application in stent deployment and transluminal extraction catheter (TEC) atherectomy.
已研发出一种新型的四口导引导管系列（8法式和9法式），用于主动脉冠状动脉静脉移植物以及静脉移植物植入部位以外的自身冠状动脉的血管成形术。在54例患者中，通过移植物对67条连续的移植物和自身血管进行扩张，手术成功率为97%。大多数手术（66%）使用G-1标准导管，但G-3导管更适用于高位前侧移植物，G-4导管更适用于高位左侧移植物。G-2导管更适用于低位右侧移植物，尤其是在扩张主动脉时。60例手术仅使用8法式导管进行球囊血管成形术，7例手术使用9法式导管进行准分子激光联合球囊血管成形术。这些独特的导引导管通过改善定位和支撑力，为现有的静脉移植物导管提供了有吸引力的替代方案。它们可能是静脉移植物血管成形术的首选，并且可能在未来用于支架置入和腔内抽吸导管（TEC）旋切术。
