Subintimal angioplasty for the treatment of claudication and critical limb ischemia: 3-year results.

Objective: Subintimal angioplasty (SIA) is an increasingly used method of lower extremity revascularization for patients with chronic arterial occlusions. To assess the technical feasibility, safety, and 3-year outcomes of patients treated with SIA, we performed a retrospective review of our early experience.

Methods: Patient information-including demographics, indications, procedures, noninvasive arterial studies, and postprocedural events-was recorded in a database.

Encouraging results with endoscopic vein harvest for infrainguinal bypass.

Background: Wound complications after infrainguinal vein bypass remain a significant source of morbidity. Endoscopic saphenous vein harvest has emerged as a viable alternative to minimize vein harvest incisions.

Methods: Infrainguinal bypass using endoscopic vein harvest was performed in 214 limbs in 197 consecutive patients between May 1998 and July 2004.

A comparison of continuous renal replacement therapy to intermittent dialysis in the management of renal insufficiency in the acutely III surgical patient.

Acute renal failure (ARF) occurs in 10 per cent to 23 per cent of intensive care unit patients with mortality ranging from 50 per cent to 90 per cent. ARF is characterized by an acute decline in renal function as measured by urine output (UOP), serum creatinine, and blood urea nitrogen (BUN). Causes may be prerenal, intrarenal, or postrenal.
