Traumatic femoral arteriovenous fistula following gunshot injury: Case report and review of literature.

ABSTRACT:

Introduction

Vascular injuries account for approximately 2-4% of trauma admissions with only 2.5% of these being traumatic arteriovenous fistulas (AVFs). We offer a case report of a traumatic AVF and review of the literature.

Presentation of case

A 40-year-old male presented following 4 gunshot wounds, 2 in the forearm and 2 in the left upper thigh. The patient had decreased range of motion and paresthesia of the left lower extremity with palpable pulses and adequate capillary refill in all extremities. A CT angiogram demonstrated a left traumatic AVF involving the left deep femoral artery and left common femoral vein with an adjacent bullet fragment. The patient was taken to the operating room and underwent an exploration of the left groin, repair of the traumatic AVF, and removal of bullet fragment. The venous aspect had a grade IV injury and was ligated. The arterial defect was debrided to healthy tissue and repaired primarily. The patient recovered from his injuries with adequate ambulation and resolution of lower extremity edema. He was discharged home on postoperative day 4 on aspirin and a compression stocking.

Discussion

Traumatic AVFs are rare, with up to 70% diagnosed in a delayed fashion. Clinicians must maintain a high index of suspicion to correctly diagnose and manage this injury to avoid potential morbidity and mortality.

Conclusion

Despite literature accounts of surgeons' experience, this pathology is lacking level one evidence-based standardized surgical management algorithms. Controversy exists regarding venous repair methods.

Project description:Background?Aorta-pulmonary (A-P) artery fistula following a stab wound to the chest with superimposed infective endocarditis (IE) is a rare, often unrecognized presentation. Herein, we report a case of A-P fistula due to stab chest assessed by two- and three-dimensional (3D) imaging.Case summary?A 30-year-old man presented with a history of being stabbed in the chest with a screwdriver. The chest wall laceration was sutured, an intercostal drain inserted for a haemopneumothorax, and he was subsequently discharged. He presented 3?weeks later with exertional dyspnoea, fever, rigours, and loss of weight. On examination, he had a wide pulse pressure and a harsh continuous murmur in the 2nd left intercostal space associated with a palpable thrill. Blood tests revealed raised infective markers and anaemia. All blood cultures were sterile. On echocardiography, the aortic and pulmonary valve was severely damaged, with suspicion of superimposed vegetations secondary to IE. There was severe aortic and pulmonary valve regurgitation. A fistulous connection was noted between the aorta and main pulmonary artery, just below the commissure adjoining the right and left coronary sinus of the aortic valve. On 3D imaging, the defect was quantified. The patient was subsequently referred for aortic and pulmonary valve replacement and closure of the A-P fistula. The presence of multiple vegetations was confirmed intraoperatively. He also received a 6-week course of intravenous antibiotics.Discussion?We have described a rare case of an A-P fistula due to a stab wound to the chest complicated by IE. In a patient with stab wound to the chest, a high index of suspicion of cardiac involvement must be maintained, and a careful search for intracardiac shunts must be made on echocardiography, prior to discharge. Furthermore, in addition to two-dimensional imaging, 3D imaging proved useful in providing a comprehensive assessment of the morphology of the lesion prior to surgery.
