From 1967 to 1979,25 patients (pts) were operated on for fibromuscular disease (FMD) of the internal carotid artery (ICA). Eleven patients (44%) had transient weakness of an extremity, 4 had amaurosis fugax and 6 (24%) had an asymptomatic carotid bruit. Bilateral carotid arteriograpby showed significant stenotic lesions in 23 pts (92%) (bilateral in 10), arterial dissection in 1, and severe associated atherosclerosis in 1. Of these, 22 pts had arteriotomy and graduated internal dilatation (GID) (9 bilateral); 2 underwent G1D with ICA endarterectomy and patch graft: 1 pt had tube graft replacement of the ICA. There was no operative mortality. One pt had a stroke during operation after tube graft replacement of the ICA. Of the 19 pts followed for 2 to 12 years (mean 7 3 years), 2 had late recurrence of mild symptoms. One pt required GID of the contralateral ICA for recurrence of symptoms 4 years postoperatively. Graduated internal dilatation of fibromuscular disease of the internal carotid artery can produce long term relief of symptoms; recurrence is rare.
