Randomized Controlled Trial Comparative Study Clinical Trial
Early results of a prospective randomized trial of spliced vein versus polytetrafluoroethylene graft with a distal vein cuff for limb-threatening ischemia.
Single-piece vein remains the conduit of choice in patients who need bypass grafting for limb salvage. When this option is not available, two of the remaining options are prosthetic bypass graft or several segments of vein spliced together. In this study, we compare spliced vein bypass grafting versus polytetrafluoroethylene grafting with a distal vein cuff in patients with limb-threatening ischemia. ⋯ Although this is a preliminary report, it appears that both spliced vein bypass grafting and polytetrafluoroethylene bypass grafting with a distal vein cuff produce acceptable limb salvage rates. The secondary patency rate for spliced vein is better, but these bypass grafts more often need revision or reoperation for wound complications.

Comparative Study
Surgical management of atherosclerotic renovascular disease.
This review describes the clinical outcome of surgical intervention for atherosclerotic renovascular disease in 500 consecutive patients with hypertension. ⋯ The surgical correction of atherosclerotic renovascular disease resulted in blood pressure benefit and retrieval of renal function in selected patients with hypertension. The patients with cured hypertension or improved EGFR after operation showed increased dialysis-free survival as compared with other patients who underwent surgery.

Comparative Study
Surgical sympathectomy for reflex sympathetic dystrophy syndromes.
The purpose of this study was the assessment of the efficacy of thoracoscopic cervicodorsal and open lumbar sympathectomy for the reduction of pain severity and disability associated with reflex sympathetic dystrophy (RSD). ⋯ Patients with RSD with a confirmed sympathetically maintained pain syndrome can realize long-term benefit from surgical sympathectomy. Procedural efficacy was similar for both upper limb and lower limb RSD syndromes, although the level of pain reduction did deteriorate with time. After sympathectomy, the patients with RSD had a low incidence rate (7%) of "new" complex regional pain or disabling compensatory sweating syndromes.

Comparative Study
Transient advanced mental impairment: an underappreciated morbidity after aortic surgery.
To determine the incidence, risk factors, and associated morbidity of transient advanced mental impairment (TAMI) after aortic surgery. ⋯ These data show that TAMI is prevalent among patients undergoing aortic reconstruction and is associated with dramatically increased morbidity and postoperative hospitalization rates.

The purpose of this study was the assessment of the safety, efficacy, and hospital charges of bedside duplex ultrasound-directed inferior vena cava (IVC) filter placement. ⋯ Our experience indicates that duplex ultrasound-directed IVC filter placement is safe, cost-effective, and convenient for patients who need IVC filter placement.
