We noted with interest a recent article entitled "The Radiographic Appearance of Arterial Sheath Kinking" [l] in which Dr. Feit and co-workers described a patient in whom angioplasty sheath kinking in the iliac artery resulted in the termination of a percutaneous transluminal coronary angioplasty procedure. They had not encountered similar problems in any of their more than 1,500 prior angioplasties. In a much smaller group of 100 patients,. we have found this phenomenon twice, both times in the same patient. We were able to proceed uninterrupted with the angioplasty.The patient was a small (160 cm, 66 kg) 73-year-old man undergoing dilitation near a coronary artery bifurcation. A bifemoral technique similar to that described previously 121 was employed using two 8-French USCI angioplasty sheaths. When the 0.063-inch J-wire could not be passed through either sheath, contrast was injected into both. The radiographic appearance in both was identical to that demonstrated by Dr. Feit. We found that traction on the sheaths accompanied by firm pushing on the catheter and guidewire allowed passage and subsequent successful angioplasty. Removal of the sheaths later the same day revealed kinks in both. In addition, the wall of one sheath was slightly stretched near the kink, apparently by force applied to the guidewire. There were no breaks in the walls of the sheaths. We conclude that in our experience arterial sheath kinking is not rare. It does not necessitate termination of a procedure.
