During the past 23 years, 12 patients with aneurysm of the carotid bif
urcation were treated in our department. There were 11 men and one wom
an between 20 and 68 years (mean age 54.2 years). In as much as 217 pa
tients were operated on for extracranial occlusive carotid disease dur
ing the same period, the incidence of these aneurysms in our series ha
s been estimated to be 5%. Eleven patients presented with TIAs ipsilat
eral to the aneurysm. One patient presented with a painful pulsatile e
nlarging mass in the neck (ruptured aneurysm) without any neurological
complications. Eleven patients underwent surgical repair. Ligation of
the common carotid artery was done in one patient, resection of the a
neurysm with end-to-end anastomosis was performed in 2 patients, aneur
ysmorraphy in 4, excision and reconstruction with reversed saphenous v
ein in one, excision and reconstruction with PTFE graft in one and 2 p
atients underwent endarterectomy and angioplasty of the carotid bifurc
ation. One patient with a high internal carotid artery aneurysm (base
of the skull) was classified as nonoperable. There were no deaths or s
trokes postoperatively. Persistent cranial nerve injury was noted in 1
case (8%). Follow-up at 6 months - 10 years (mean 5.5 years) yielded
and incidence of post-op TIAs of 8% attributed to intracranial occlusi
ve disease. Surgical correction is the treatment of choice for extracr
anial carotid aneurysm and can be performed with a very low morbidity
and mortality and carries excellent long-term results.
