The use of operative arteriography during carotid endarterectomy facilitates identification and correction of technical errors. Although arteriography is the standard for assessing surgical results, it prolongs the operation and may increase the overall risk. The purpose of this study was to evaluate pulsed Doppler spectral analysis and arteriograp...

Nineteen patients with 20 occluded arterial bypass grafts were treated with local infusion of streptokinase. Grafts treated included four aortofemoral graft limbs, 14 femoropopliteal or femorotibial grafts, one axillofemoral graft, and one transpubic femorofemoral graft. Complete lysis of thrombus was possible in 12 patients, partial lysis in five ...

Proper selection of suprainguinal vs. infrainguinal arterial revascularization in patients with multilevel disease requires hemodynamic assessment. In such patients hemodynamic evaluation of the aortoiliac system cannot be made accurately with either arteriography or current noninvasive techniques. One hundred six lower extremities underwent preope...

Nine hundred forty carotid endarterectomies were performed without the use of a temporary indwelling shunt. Six patients (0.6%) died, all from stroke; 17 other patients (1.8%) had another stroke, and 21 patients (2.2%) had temporary neurologic symptoms. Complete x-ray films detailing the opposite internal carotid artery and carotid artery back pres...

The records of 111 consecutive patients undergoing evaluation for possible carotid endarterectomy at the University of Rochester were reviewed. All patients had noninvasive evaluation (oculoplethysmography-Gee and direct, continuous-wave Doppler ultrasonography) as well as selective carotid angiography. Patients were grouped by clinical presentatio...

The use of transcutaneous oxygen tension (TCpO2) measurements to objectively and noninvasively diagnose peripheral arterial occlusive disease (PAOD) and to aid in the planning of vascular surgery was investigated. Thirty-two normal subjects and 100 patients with PAOD were studied. TCpO2 values decreased with age; when normalized by measurements on ...

From January 1979 through December 1982, 2026 patients scheduled to undergo open heart surgery were evaluated by a preoperative battery of noninvasive carotid tests including phonoangiography, oculopneumoplethysmography, pulse-timing oculoplethysmography, periorbital Doppler examination, and during the last 12 months, continuous-wave Doppler ultras...

Over a 4-year period 335 patients underwent 402 carotid endarterectomies: 227 (56%) for carotid territory symptoms, 107 (27%) for nonhemispheric symptoms, and 68 (17%) for asymptomatic lesions. In 317 four-vessel arteriograms, proximal subclavian and/or vertebral lesions were found more frequently in the nonhemispheric group (80 of 97, or 82%) than...

Composite grafts of polytetrafluoroethylene (PTFE) and saphenous vein were used for sequential bypasses to the ankle and foot in 35 men and 19 women (mean age 66.5 years). Presenting symptoms were rest pain (25), digital gangrene (19), and ischemic ulcer (10). Thirty-one tibial and 23 pedal bypasses were done and were followed up to 48 months (mean...
