Hypertension because of an arteriovenous fistula between the right renal artery and the inferior vena cava secondary to a gunshot wound: a case report.

A case of a renovascular hypertension due to an arteriovenous fistula between the right renal artery and the IVC secondary to a gunshot wound 8 years previously is reported. The diagnosis was made initially by the clinical signs of a continuous bruit heard over the anterior abdomen and by the characteristic findings of diastolic hypertension. Diagnosis was confirmed by abdominal aortography. In the operation, the right renal artery was ligated and divided proximally between the aorta and the aneurysm and distally beyond the fistulous communication and a Gore-Tex graft was anastomosed between distal part of the renal artery and abdominal aorta. The result was confirmed by postoperative aortography and by disappearance of the preoperative physical findings. The present case, to our knowledge, is the sixth in the literature.
