Abstract:

Objective:

Arterial vascular complications resulting from thoracic outlet compression, although rare, can be substantial and potentially limb threatening. These complications are due to compressions at the thoracic outlet, the treatment of which continues to be a dilemma. The objective of the present study was to review our experience with this problem with particular reference to its management. Methods:

We performed a retrospective study of 12 years and retrieved data from the medical records department of Nizam's Institute of Medical Sciences, Hyderabad, India. A retrospective review identified 35 patients (age range 15–50 years). In 31 patients, the vasculopathy was caused by a cervical rib, soft tissue anomalies (n = 31), and an elongated transverse process (n = 4). Evaluation included assessment with colour duplex and arteriography with positional maneuvers. Thirty-two patients presented with a fixed pulse deficit, 22 patients had palpable mass and 15 patients had distal embolization. Results:

In 31 patients with cervical rib, the rib was excised via a supraclavicular approach, Scalenectomy was performed and the arterial pathology was repaired on its merit, usually by a vein graft replacement or bypass. The elongated process was excised in the other four patients. Twelve patients required thrombectomy of the distal arteries and a bypass procedure (with a vein/prosthetic graft) was performed in 14 patients. Dorsal sympathectomy, as an adjunct, was carried out in 10 patients. In view of their advanced distal disease, four patients were given prostaglandin therapy. Short-term follow up of 2 years showed good results. Conclusion:

Our results show that simple excision of the cervical rib with scalenectomy via supraclavicular approach, together with arterial reconstruction (if required) is adequate for arterial vascular complications resulting from thoracic outlet compression. Patients with severe distal disease may require other adjunct procedures like dorsal sympathectomy or prostaglandin infusions along with proximal reconstruction.
