Subclavian vein thrombectomy is a procedure used to remove blood clots that are obstructing the subclavian vein, which drains blood from the arm. The procedure is typically performed when a clot leads to symptoms like swelling, pain, or difficulty in accessing venous access points for dialysis. Thrombectomy involves surgically removing or dissolving the clot to restore normal blood flow and alleviate symptoms.

This surgery is effective in preventing complications like post-thrombotic syndrome and reducing the risk of further clot formation or venous congestion.
