Management of traumatic subclavian artery injuries in a high-volume vascular surgery center in Iran

Introduction: Subclavian artery injury is an uncommon vascular trauma with potential morbidity and mortality. Management of subclavian artery trauma requires open and endovascular techniques and timely and efficacious decision is mandatory. We retrospectively reviewed traumatic subclavian artery injuries in a high-volume vascular surgery center in Iran. Methods: In a retrospective study, we assessed subclavian artery injuries during 6 years in ShohadaTajrish Medical Center. Background characteristics, type of incision, type of operation and outcome of patients were evaluated. Results: A total of 14 patients had subclavian artery injury (mean age 29.9 ± 13.4 years, 92.9% male). Trauma was in left and right sides in eight (57.1%) and six patients (42.9%) respectively. Arteriorrhaphy, interposition and ligation of injured artery was done in 7 (50.0%), 3 (21.4%) and 4 (28.6%) patients respectively. Associated nerve injury was present in six patients (42.9%). Endovascular proximal control was obtained in six patients (42.9%) prior to vascular exposure. Time of patient referral did not have significant association with shock or type of operation (P > 0.05). Conclusion: Although traumatic subclavian artery injuries are rare, its vascular exposures and reconstructions are of potential clinical concern. Endovascular interventions can facilitate proximal control. In addition, endovascular repair by covered stent is an alternative to open surgery.
