Fig 1 Congenital aorto-azygous fistula complicated by arteriovenous aneurysm. (A and B) Three-dimensional reconstruction of the great vessels shows that the feeding artery (black arrow) originated from the descending aorta, entered into the right thoracic cavity, expanded, and formed the arteriovenous aneurysm (white arrow) with a fistula draining into the azygos vein (black triangle). (C and D) Intraoperative stereogram of the aberrant feeding artery (black arrow), arteriovenous aneurysm (white arrow), and dilated azygos, which was ligated later (black triangle).

Fig 2 Intraoperative thoracoscopic view showed the dissociation and resection of the aberrant feeding artery (black arrow) using 30-mm Endo GIA camel ultra universal Tri-Stapler. (A) Exposure of the abnormal artery following the ligation and transection of the azygos vein (triangle); (B) Isolation of the aberrant artery and around it with a catheter; (C) Occlusion of the aberrant artery by one Endo-GIA stapler; (D) Cutting of the aberrant artery.

Fig 3 Computed tomographic reexamination showed that (A and B) communicating artery had been cut and sutured definitively and that (C and D) the arteriovenous aneurysm became smaller with partial thrombogenesis. Black arrow: Cross-sectional scanning of the aberrant artery (A: preoperative; C: postoperative); White arrow: Coronal reconstructed image of the aberrant artery (B: preoperative; D: postoperative).
