Figure 8. Intraoperative image from case 2. (A) Left supraclavicular approach with observation of the phrenic nerve (yellow strap), the subclavian artery (ASC), and the anterior scalene muscle (EA); (B) After anterior scalenectomy, the cervical rib (black arrow) and aneurysm (*) were identified; (C) After medial scalenectomy and resection of the cervical rib, the aneurysm was identified (*). The outlet was free from compression; (D) The aneurysm was resected and the artery was reconstructed with end-to-end anastomosis with interrupted stitches, using the Carrel triangulation technique.
