BACKGROUND: The purpose of this study was to analyze the outcomes of revascularization exceeding 12 h after arterial injury at different sites of the lower extremity.
MATERIAL AND METHODS: From January 2009 to April 2017, 58 patients with 58 lower-limb arterial injuries who underwent revascularization over 12 h after trauma were included in our study. Outcomes measured, including mortality, amputation, complications, and other parameters (gait, length discrepancy, the range of movement of the knee and ankle joint, and muscle wasting) were analyzed.
RESULTS: External iliac artery injury (EIAI) or femoral artery injury (FAI) was affected in 4 patients, superficial femoral artery injury (SFAI) in 18, and popliteal artery injury (PAI) (including proximal gastrocnemius muscle vascular (PGMV) and proximal gastrocnemius muscle vascular [PGMV]) in 36. The median time of arterial injury was 72 h (interquartile range, 59.5). No mortality was found. Amputations were performed in 16 patients due to non-viable limbs, progressing infection, or muscle necrosis. All patients were followed up (median, 52 months; interquartile range, 5.5). Of the 42 limb-salvage patients, most had a limp, muscle wasting, or ankle and knee dysfunctions, and 26 patients with knee or ankle dysfunction underwent secondary surgery.
CONCLUSIONS: Although limited recanalization of blood vessels may lead to limb complications or amputations over time, the high success rate of limb salvage still merits the surgeon’s best efforts.
