Mortality and reoperations following lower limb amputations.

摘要: Background Above-the-knee amputations (AKA) and below-the-knee (BKA) are commonly indicated in patients with ischemia, extensive tissue loss, or infection. AKA were previously reported to have better wound-healing rates but poorer rehabilitation than BKA. Objectives To compare the outcomes of BKA identify risk factors for poor outcome following leg amputation. Methods This retrospective cohort study comprised 188 consecutive (mean age 72 years, range 25-103, 71 males) who underwent 198 (91 AKA, 107 BK 10 bilateral procedures) between February 2007 May 2010. Included male female adults ischemic, infected gangrenotic foot. Excluded whose surgery was performed other indications (trauma, tumors). Mortality reoperations (wound debridement need conversion a higher levelof amputation) evaluated as outcomes. Patient- surgery-related studied relation these primary Results The mortality dementia [hazard ratio (HR) 2.769], non-ambulatory status preoperatively (HR 2.281), heart failure 2.013) renal 1.87).
