ASYMPTOMATIC CONGENITAL THORACIC ARTERIO-VENOUS FISTULA BETWEEN DESCENDING THORACIC AORTA AND LEFT BRACHIOCEPHALIC VEIN

Thoracic aortovenous stulae are rare entities where a direct shunt between thoracic arteries and systemic veins is seen. They can be traumatic or congenital in origin. Congenital thoracic aortovenous stulae usually involve descending aorta and azygos, hemiazygos systems. Rarely, they can occur with brachiocephalic vein or vena cava. Presenting symptoms range from continuous murmur to signs of congestive heart failure. Here we have reported a case of 69-year-old female who underwent computed tomography of neck and thorax for complaint of change of voice, which incidentally revealed an aberrant vessel originating from descending aorta and draining into the left brachiocephalic vein.
