We studied the use of "Monorail" system with Express (Scimed) balloon catheters for coronary angioplasty through 6 French (F) "high-flow" diagnostic catheters (Novoste, USCI). Prospectively, from July 1992 to January 1993, angioplasty of 31 lesions in 24 patients was attempted (1.3 lesions/procedure). Twenty procedures were of a single lesion and four were multi-vessel angioplasty. Fourteen lesions were in the left anterior descending or in its branches, 10 in the left circumflex or in its branches, 6 in the right coronary artery, and one in the distal anastomosis of an internal mammary artery graft. Thirteen lesions (42%) were type A, 17 (55%) type B and one (3%) type C. Balloon sizes varied between 2.0 and 3.5 mm. Twenty-nine lesions could be successfully dilated (93.5%); two cases were unsuccessful due to an acute occlusion in one and residual stenosis of more than 50% in the other. For only one case, another balloon catheter different from the "Monorail" system was necessary to complete a multi-vessel angioplasty. Coronary visualization and manipulation of the balloon through the tip of the diagnostic catheter were satisfactory in all cases, except with the 3.5 mm balloon catheter. Coronary angioplasty with "Monorail" system balloon catheters through 6 F "high-flow" diagnostic catheters is feasible and provides a high success rate in simple and moderately complex selected lesions, including multivessel angioplasty with advantages of smaller artery punction and the feasibility of performing coronary angioplasty with the same catheter used for diagnostic angiography.
我们研究了通过6法国（F）“高流量”诊断导管（Novoste，USCI）使用带有快速交换（Scimed）球囊导管的“单轨”系统进行冠状动脉血管成形术。前瞻性地，从1992年7月至1993年1月，对24例患者的31处病变尝试进行血管成形术（1.3处病变/手术）。20例手术为单处病变，4例为多支血管血管成形术。14处病变位于左前降支或其分支，10处位于左旋支或其分支，6处位于右冠状动脉，1处位于乳内动脉移植物的远端吻合处。13处病变（42%）为A型，17处（55%）为B型，1处（3%）为C型。球囊尺寸在2.0至3.5毫米之间变化。29处病变（93.5%）能够成功扩张；2例未成功，1例因急性闭塞，另1例因残余狭窄超过50%。仅1例需要使用与“单轨”系统不同的另一个球囊导管来完成多支血管血管成形术。除了3.5毫米球囊导管外，在所有病例中通过诊断导管尖端进行冠状动脉显影和球囊操作均令人满意。通过6F“高流量”诊断导管使用“单轨”系统球囊导管进行冠状动脉血管成形术是可行的，并且在简单和中度复杂的选定病变中成功率很高，包括多支血管血管成形术，具有动脉穿刺较小以及使用与诊断性血管造影相同的导管进行冠状动脉血管成形术的可行性等优点。
