本文报道42例右冠状动脉(RCA)经皮冠状动脉腔内成形术(PTCA)中应用双环导管的临床资料。当RCA近端为水平或下位时，使用主弯90度的导管。当右冠状动脉近段位于上方(牧羊人弯曲处)时，使用一次弯曲75度的导管。导管由短(1.5 cm)或长(2.3 cm)(USCI，C.R.Bard，Inc.，Billerica，MA)远端制造。短尖导尿管在大多数情况下是满意的。当RCA过程复杂且需要更多后备或升主动脉较宽时，长尖导管被发现是最佳选择。42名连续的患者尝试了49个病变的血管成形术。39例患者扩张成功(93%)。在三名患者中，手术没有成功。在一名患者中，尽管有很好的后备，但病变无法与导丝相交。在另一位患者中，三处狭窄中的两处扩张成功；远端病变被导丝穿过，但尽管有良好的后备，仍无法与球囊导管相交。缺乏令人满意的参与和不充分的后备是仅有一名患者失败的原因。未发现与导尿管相关的并发症。结论：双环导管是安全的，可作为冠脉成形术的首选导管。这些导管提供了一个很好的备份，因此成功率很高。
Double loop guiding catheters have been used for percutaneous transluminal coronary angioplasty (PTCA) of the right coronary artery (RCA) in 42 consecutive cases. A catheter with a 90‐ degree primary curve was used when the proximal RCA had horizontal or inferior orientation. When the proximal segment of the RCA was oriented superiorly (shepherd's crook), the catheter with a 75‐degree primary curve was used. Catheters were fabricated with short (1.5 cm) or long (2.3 cm) (USCI, C.R. Bard, Inc., Billerica, MA) distal tips. Short‐tip catheters were satisfactory in the majority of cases. When the RCA had a complex course and more backup was necessary or when the ascending aorta was wide, long‐tip catheters were found to be the best choice.Angioplasty of 49 lesions was attempted in 42 consecutive patients. In 39 patients successful dilatation was achieved (93%). In three patients the procedure was unsuccessful. In one patient, the lesion could not be crossed with the guidewire despite an excellent backup. In another patient, two of three stenoses were dilated successfully; the distal lesion was crossed with a guidewire but could not be crossed with the balloon catheter in spite of a good backup. The lack of a satisfactory engagement and inadequate backup were responsible for the failure in only one patient. There were no complications related to these guiding catheters. We conclude that double loop guiding catheters are safe and can be the primary choice in all right coronary angioplasties. These catheters provide an excellent backup with consequent high success rate.
