Thrombosis of axillary-femoral bypass secondary to prosthesis suspension belt.

Patients with peripheral vascular disease and lower extremity amputation frequently undergo arterial bypass surgery to salvage the opposite leg. Compression of axillary-femoral bypass grafts can occur from a variety of causes. The primary physician should monitor graft pulses closely. Compression should be avoided by using forearm crutches instead of axillary crutches. Waist belts for prosthetic support should not be used, and alternatives such as a thigh corset or shoulder suspension should be used. The patient should avoid sleeping on the graft, using a wrist restraint when necessary. If the patient gains weight, garments should be adjusted so as not to be constricting. Upper extremity exercises, particularly in should abduction and extension, should not be so vigorous as to put tension on the graft. A 77-year-old woman with a left below-knee amputation underwent an axillary-femoral bypass for right lower extremity arterial insufficiency which subsequently thrombosed due to compression by the waist belt of her below-knee prosthesis. A series of guidelines are outlined, so that the physiatrist can help maintain graft patency, prolong limb salvage, and avert similar complications in such patients.

Two cases of spontaneous lysis of arterial thrombi.

Two cases of spontaneous lysis of arterial thrombi are described. The occurrence of spontaneous thrombolysis and the relative ease of performing Fogarty embolectomy (thrombectomy) in peripheral arteries should be considered along with the clinical status of a patient who is viewed as a possible candidate for thrombolytic therapy, a procedure which has a potential for severe hemorrhagic complications.

Ex vivo renal artery reconstruction.

Twenty-four patients underwent ex vivo renal artery reconstruction of 26 extensive lesions using continuous hypothermic perfusion and replacement of the diseased renal artery with a hypogastric artery autograft. Postoperative acute tubular necrosis was avoided in these repaired kidneys. There was one postoperative graft occlusion accounting for the only failure in the series. Of the hypertensive patients, 95% were cured or improved during the follow-up period extending from six months to six years. Six of these patients have been followed more than three years and late postoperative arteriograms showed no alteration in their autografts. This method, therefore, extends the potential for renal artery reconstruction to most renal vascular lesions, reserving nephrectomy for the infarcted or severely atrophic kidney only.
