PurposePurpose of this study was to report the etiology, diagnosis, surgical management, and outcome of pseudoaneurysm associated with orthopedic trauma.MethodsA retrospective review was conducted of all patients presenting to a Level 1 trauma center between 2013 and 2019. Clinical records were reviewed for the mechanism of primary injury, associated fracture pattern, time of presentation, site of involvement, etiology of the pseudoaneurysm, diagnosis, management, and complications. We identified 14 patients with pseudoaneurysm of peripheral arteries following orthopedic trauma.ResultsThe mean interval between primary injury and the manifestation of clinical symptoms was 88.5 days (range, 16-304 days). There were 3 upper limb injuries and 11 lower limb injuries. The presenting symptoms were pain associated with excessive extremity swelling in most of the patients. A significant drop in hemoglobin (mean fall- 2.9 g/dL) was noted in nine patients. Most common artery involved was the superficial branch of femoral artery and posterior tibial artery followed by the brachial artery. Fractured bone spike was the cause of injury in eight patients and iatrogenic injury in six patients. Diagnosis was confirmed by CT angiography with duplex scan in eight patients, duplex scan alone in one patient, MRI along with duplex scan in one patient. The remaining four patients were diagnosed intraoperatively. Excision of the pseudoaneurysm and ligation of the involved minor arteries was done in eight patients. Surgical repair of the major artery with critical vascular injury was done in six patients. One patient underwent secondary amputation following the anastomotic blowout.ConclusionEarly diagnosis of pseudoaneurysm requires knowledge and a high index of suspicion. Surgical reconstruction of major arteries should always be done and ligation of major vessels can lead to catastrophes. Excision of pseudoaneurysm can be done when minor arteries are involved with the presence of good collateral circulation.Level Of StudyLevel IV Study.© 2020.
