Treatment

Emergency Department Care

Most presentations of thoracic outlet syndrome (TOS) to the ED are nonemergent and require only symptomatic treatment and referral. Vascular thoracic outlet syndrome, although much less common than neurologic thoracic outlet syndrome, requires more urgent care.

Management of vascular (arterial and venous) TOS includes the following:

  • Immediate heparinization
  • Vascular surgery consultation
  • Color flow duplex scanning
  • Angiography or venography

Neurologic TOS is generally managed with conservative outpatient physiotherapy.

Hospitalization

Patients with vascular TOS may be admitted for the following:

  • Angiography or venography
  • Color flow duplex scanning
  • Catheter-directed local infusion of thrombolytic agent
  • Thrombectomy (for total thrombotic obstruction)
  • Fogarty catheter embolectomy
  • Emergent or urgent surgical exploration

Operative therapy is indicated for neurologic TOS if conservative approach fails. [6]

Supraclavicular decompression techniques may include anterior and middle scalenectomy, excision of a cervical rib if present and first rib resection. [1, 7]

Using a prospectively maintained database, Orlando et al. retrospectively evaluated the outcomes of 538 patients who underwent first rib resection (FRR) for indications of neurogenic, venous, and arterial thoracic outlet syndrome (TOS) from August 2003 through July 2013. A comparison of the second 5-year period with the first 5-year period showed that improved or fully resolved symptoms increased from 93% to 96%. The mean length of stay was 1 day. [8]

A retrospective survey of 158 workman's compensation patients undergoing surgery for thoracic outlet syndrome (TOS) showed that 60% were still work-disabled 1 year after surgery. [9]

Consultations

Neurologic, orthopedic, or vascular surgery consultation(s) may be indicated depending on the type of pathologic condition.

Physical medicine and rehabilitation physicians are needed for outpatient workup.

Transfer

For patients with vascular TOS, transfer to a center with experience in such cases for definitive diagnosis and treatment if it is unavailable at the current institution.
