A new type of steerable guiding catheter is described for use in percutaneous transluminal coronary angioplasty (PTCA). It is simple to use and externally steerable. The catheter incorporates a steering system by means of which the catheter tip can be made to assume the form of either a right or left Judkins catheter or to be fixed in any intermediate configuration, entirely through external manipulation. We used this new guiding catheter to perform PTCA on 15 patients. Single lesions were found in the left anterior descending branch in seven patients, in the right coronary artery in four, and in the circumflex artery in two, whereas stenosis of a coronary bypass graft was found in two patients. Angioplasty was successful in all cases. There were no complications, during either the procedure or the postoperative hospitalization. The steerable guiding catheter described here may prove useful for PTCA in cases where a conventional catheter cannot be placed accurately or in cases with multi-vessel coronary disease.
本文描述了一种用于经皮腔内冠状动脉成形术（PTCA）的新型可操纵导引导管。它使用简单且可在体外操纵。该导管包含一个操纵系统，通过该系统，完全通过外部操作可使导管尖端呈右或左Judkins导管的形状，或固定在任何中间构型。我们使用这种新型导引导管对15例患者进行了PTCA。7例患者左前降支发现单一病变，4例患者右冠状动脉发现病变，2例患者回旋支发现病变，2例患者冠状动脉搭桥移植血管狭窄。所有病例血管成形术均成功。术中及术后住院期间均无并发症。本文所述的可操纵导引导管可能在传统导管无法准确放置的情况下或多支冠状动脉疾病的情况下对PTCA有用。
