Methods: Eleven male patients (mean age 27.5±11.4 years; range 17 to 49 years) who underwent ligation for DFA injuries were retrospectively evaluated with respect to demographic features, etiology, time from injury to presentation, physical examination findings at the emergency unit, diagnostic methods used, surgical procedures, and early and midterm results of treatment.
Results: Etiology was gun shot injury in six patients (54.6%) and stab wound in five patients (45.5%). Nine patients (81.8%) presented within the first two hours after trauma. The ankle-brachial pressure index (ABI) was 1 in all the patients. A large vascular defect was present in all the patients, involving the branches of the DFA. Five patients had an isolated DFA injury, while six patients had accompanying venous injuries. Four patients (36.4%) with active bleeding were promptly submitted to surgery because physical examination findings were sufficient for diagnosis. Seven patients (63.6%) were operated on after clinical observation ranging from 2 to 17 hours (mean 6.7 hours). The mean hospital stay was 9.3±7.1 days (range 4 to 24 days). Early postoperative complications included local wound infection in two patients. No pathological findings were detected during a mean follow-up period of 16.3±11.0 months (range 2 to 33 months).
Conclusion: Clinical observation up to 24 hours is important in patients whose manifestations of DFA injuries are not apparent. Measurement of ABI may not be a reliable tool for the diagnosis of DFA injuries. Ligation may be a treatment option in young cases in which surgical repair is not possible.
