Purpose: Vascular thoracic outlet syndrome (TOS) can present with signs of arterial impingement or, more commonly, as venous obstruction. In an effort to decrease morbidity associated with vascular thoracic outlet syndrome, we have used an aggressive multimodal treatment approach.
Methods: Since November 1992, we have evaluated 29 patients with vascular thoracic outlet syndrome. Nine of ten patients with arterial thoracic outlet syndrome had first rib resections. Eighteen of 19 patients with venous occlusion underwent anticoagulation, thrombolysis, and first rib resection. Eight patients required additional endovascular therapy for persistent stenoses, either venous angioplasty alone (2) or angioplasty plus stent placement (6).
Results: Follow up extends to 75months with a mean of 24months. Patients with stents have been followed for a mean of 38months. Twenty-five of 28 patients managed with multimodal therapy were essentially asymptomatic at last follow up.
Conclusion: Thrombolysis, anticoagulation, surgical decompression, and endovascular procedures act synergistically to improve results of therapy in patients with vascular thoracic outlet syndrome.
