Subclavian vein reconstruction is a surgical procedure performed to treat blockages or narrowing of the subclavian vein, which is a major vein that drains blood from the arms. The procedure may involve removing the blockage, using a graft to bypass the obstructed area, or stenting the vein to restore normal blood flow.

This surgery is crucial for alleviating symptoms such as arm swelling, pain, or venous congestion, and preventing long-term complications like blood clots or tissue damage.
