When she was referred to us, computerized tomography revealed a poorly marginated and enhanced tumor that had occluded the subclavian vein and adhered to the subclavian artery at the infraclavicular lymph node (Figure 1).
Intra-operative findings and removal of the adventitia of the subclavian artery. (a) After resection of the tumor and collarbone, the right subclavian artery and axillary artery (arrow) were controlled so that bleeding was not observed. (b) The subclavian and axillary arterial walls including intima were opened. Bleeding was not observed. (c) The arterial wall including intima was completely resected.

Surgical bleeding was not observed (Figure 2).
The entire length of the stent was wrapped with an artificial blood vessel (8 mm Advanta  VXT with ring; Atrium Medical Corporation, USA) to prevent stent migration and bleeding.

To prevent the stent from moving and causing bleeding, we wrapped the entire length of the stent with an artificial blood vessel (8 mm Advanta  VXT with ring; Atrium Medical Corporation, Ethicon, USA) and fixed the artificial vessel to the proximal and distal sides of the native artery with a running suture with 6-0 prolene (Figure 3).
