Summary
Surgical treatment for thoracic outlet syndrome effectively addressed vascular issues like arm ischemia and venous hypertension. First rib resection improved symptoms in most patients, with outcomes linked to the severity of arterial blockages.
Area of Science:
- Vascular Surgery
- Thoracic Outlet Syndrome
- Upper Extremity Vascular Conditions
Background:
- Thoracic outlet syndrome (TOS) can cause significant vascular complications affecting the arm and hand.
- These complications include arterial microemboli leading to ischemia and venous hypertension due to thrombosis or extrinsic compression.
Purpose of the Study:
- To evaluate the surgical outcomes for patients with vascular sequelae of TOS.
- To assess the efficacy of arterial reconstruction, first rib resection, and sympathectomy in managing TOS-related vascular issues.
Main Methods:
- Retrospective review of 11 patients undergoing surgery for vascular TOS over 17 years.
- Treatment involved arterial reconstruction, compressive structure removal, cervical sympathectomy for arterial cases, and transaxillary first rib resection for venous cases.
Main Results:
- Five patients with arterial TOS (ischemia) showed good/excellent results after surgery; one required amputation. Outcomes correlated inversely with distal embolic occlusion extent.
- Six patients with venous hypertension improved symptomatically after first rib resection (4 with thrombosis, 2 with extrinsic compression).
Conclusions:
- Transaxillary first rib resection is an effective treatment for venous hypertension secondary to TOS.
- Surgical management of arterial TOS yields variable results, influenced by the degree of distal arterial disease at presentation.
