Double-loop guiding catheters have been used for angioplasty of aorto-coronary vein grafts (VG) or grafted arteries through the VG in 31 cases. A catheter with a 90 degrees primary curve was usually the best choice for angioplasty of the VG to the right coronary artery (RCA). For angioplasty of the VG to the left coronary artery branches (LCA), a 90 degrees primary curve was used when the proximal segment of the VG was oriented horizontally and a 75 degrees (USCI, C.R. Bard, Inc., Billerica, MA) was used when the proximal segment was directed superiorly. Angioplasty of 32 lesions was attempted in 31 patients. These catheters provided good "back-up" in angioplasty of 30 lesions (94%). The lesions were crossed with balloon catheters in 29 cases (91%). There was one acute VG occlusion requiring coronary artery bypass graft (CABG) surgery, a complication not attributed to the guiding catheter. We conclude that Arani guiding catheters provide strong back-up, are helpful in angioplasty of the vein grafts, and could be used as the primary choice for VG angioplasties.
双弯引导导管已用于31例主动脉-冠状动脉静脉桥血管（VG）或经静脉桥血管对移植动脉进行血管成形术。对于右冠状动脉（RCA）的静脉桥血管成形术，具有90度初始弯曲的导管通常是最佳选择。对于左冠状动脉分支（LCA）的静脉桥血管成形术，当静脉桥血管近端段水平走行时使用90度初始弯曲，当近端段向上走行时使用75度（USCI，C.R. Bard公司，马萨诸塞州比勒里卡）的导管。31例患者尝试对32处病变进行血管成形术。这些导管在30处病变（94%）的血管成形术中提供了良好的“支撑”。29例（91%）病变通过球囊导管穿过。有1例急性静脉桥血管闭塞需要冠状动脉旁路移植术（CABG），这一并发症与引导导管无关。我们得出结论，阿拉尼引导导管提供了强大的支撑，有助于静脉桥血管的血管成形术，可作为静脉桥血管成形术的首选。
