A new catheter technique to perform angioplasty of the right or left internal mammary artery coronary graft utilizing the brachial artery approach is described. Utilization of the ipsilateral brachial artery permitted cannulation of the internal mammary artery with preformed polyurethane Teflon-lined guide catheters. The coronary dilatation catheter was passed through the guiding catheter into the internal mammary artery. This technique permitted successful access into the ipsilateral mammary artery in eight patients, the left internal mammary artery graft in five and the right in three patients. The angioplasty procedure was successfully performed in seven of eight cases (spasm of the left internal mammary artery precluded successful dilatation catheter passage in one case). No brachial artery complications were encountered. In two cases, angioplasty was successfully performed in additional coronary vessels. Follow-up of 1-16 months (mean: 7.7 months) revealed no clinical evidence of restenosis. The ipsilateral brachial artery approach utilizing preshaped guiding catheters for visualization and introduction of dilatation catheters into the internal mammary artery graft is a safe and successful approach, and it is an acceptable alternative to the femoral technique.
描述了一种利用肱动脉入路对右或左乳内动脉冠状动脉移植血管进行血管成形术的新导管技术。利用同侧肱动脉，可使用预制的聚氨酯衬里导引导管对乳内动脉进行插管。冠状动脉扩张导管通过导引导管进入乳内动脉。该技术在8例患者中成功进入同侧乳内动脉，5例进入左乳内动脉移植血管，3例进入右乳内动脉移植血管。8例中有7例成功进行了血管成形术（1例因左乳内动脉痉挛导致扩张导管未能成功通过）。未出现肱动脉并发症。2例患者在其他冠状动脉血管中成功进行了血管成形术。1至16个月（平均7.7个月）的随访显示，无再狭窄的临床证据。利用预塑形导引导管通过同侧肱动脉入路来观察并将扩张导管引入乳内动脉移植血管是一种安全且成功的方法，是股动脉技术的可接受替代方法。
