BACKGROUND: Soft tissue lower limb reconstruction often requires free tissue transfer. We investigated whether the target vessels used for micro-vascular anastomosis in the lower limb influences microsurgical outcomes.
METHODS: Data from Plastic Surgery Departments of a major tertiary hospital in the United Kingdom (Leeds General Infirmary, LGI) and Australia (Princess Alexandra Hospital, PAH) were retrospectively analysed. Patients who underwent lower limb free flap reconstruction using the posterior (PTA) or anterior tibial artery (ATA) were included. Patient demographics, free flap and microvascular anastomosis details were analysed. Primary outcome was flap failure. Secondary outcome was return to theatre.
RESULTS: Two hundred and thirty-four free flaps were included (PAH 115; LGI 119). 60% were muscle flaps. Eighty-one percent of patients were male, with trauma the cause in 82%. PTA was used for microsurgical anastomosis in 70% of cases. Venae comitantes were preferred (96%) for venous anastomosis. PTA group showed a higher proportion of patients with trauma as the mechanism of injury. ATA group was more likely to have an end-to-end arterial anastomosis configuration. Total flap loss was 3.8%. There was no clinically significant difference in flap failure or return to theatre using ATA versus PTA.
CONCLUSIONS: Incidence of lower limb free flap failure is low (<5%) and not influenced by use of ATA versus PTA for microsurgical anastomosis. The choice of target vessels for microsurgical reconstruction of the lower limb should be predicated upon factors other than aversion to one or another vessel. If all other microsurgical considerations are equal, the surgeon can exercise personal preference.
