Venous TOS Management After Axillosubclavian Thrombolysis Has Not Restored Normal Vein Patency

Venous thoracic outlet syndrome (VTOS) arises from extrinsic compression of the subclavian vein at the costoclavicular junction. Patients typically present with arm swelling, discoloration, heaviness, or acute subclavian vein thrombosis.

The Clinical Scenario

In VTOS, intermittent compression or partial or complete thrombosis of the subclavian vein at the costoclavicular junction drives the clinical picture. When initial thrombus removal is attempted and the vein does not normalise, a clear escalation pathway is indicated.

Previous treatment — insufficient response

Axillosubclavian venous thrombolysis — whether by conventional infusion or pharmacomechanical technique with adjunctive balloon venoplasty — did not achieve fully successful thrombolysis with a normal residual vein at rest and with arm elevation. This protocol addresses the next step when those targets are not met.

Next-Step Approach

The structured protocol for this situation involves an operative or interventional approach targeting the underlying obstruction. The specific procedure, sequence, and clinical decision points are detailed in the full protocol…
