The role of preoperative radiological assessment of vascular injury on surgical decision making in mutilating injuries of the upper extremity.

Preoperative assessment of the extent of vascular injury is important in patients with mutilating injuries of the upper extremity. The aim of this report was to discuss the influence of computed tomography angiography (CTA) and digital subtraction angiography (DSA) on the operating room decision-making in mutilating injuries and limb-salvage procedures of the traumatic upper extremity. Four DSA and 3 CTA were performed in 7 patients with a mean age of 28.3 (range, 4-48) years. The results of the DSA and CTA altered the preoperative planning. In 5 patients, the reconstructive decision of the type of flap was altered, whereas in all 7 patients, either the level or type of anastomosis was changed after radiologic investigations. The mean follow-up period was 37.8 months. During the follow-up period, all patients underwent subsequent procedures such as sensory restoration, tendon reconstruction, or capsulotomy. The effects of radiologic results in which flap selection, target donor vessel, and level and type of anastomosis have changed are discussed in correlation with intraoperative findings.
