Takayasu's arteritis: diagnostic considerations and surgical treatment.

A 20-year-old white woman with Takayasu's arteritis had headaches, neck soreness, and a right carotid bruit. Corticosteroid treatment only temporarily relieved symptoms and caused Cushing's syndrome because of high dosage requirements. Progressive narrowing of the right common carotid artery occurred despite treatment. The diseased portion of the artery was successfully resected and replaced by a Dacron graft. Corticosteroid treatment was then tapered and discontinued, and the patient has remained well for 3 years. Carotid Doppler and real-time ultrasound studies performed more than 2 years after surgery showed a patent graft and no new disease process. This technique may be of value in selected cases for both prevention of cerebral ischemia and the elimination of local symptoms of the inflammatory process.
