A study of 11 cases of Takayasu's disease, collected from the cardio-vascular surgical service of Sfax, has been realized during the 4 year-period from 1988 to 1991. Womanly predominance was neat. The average age was 40 years, with extremes of 24 and 56 years. Dominant revealing symptoms was upper limb ischaemia found in 9 cases, a reno-vascular hypertension rebelled to medical treatment was noted in 2 cases. Arteriography have showed a preferential localization of lesions in the subclavian artery essentially at the post-vertebral segment. Lesions types were dominated by stenosis and obliteration, then aneurysms were rare. Operative indication was posed in 9 cases. 11 revascularisations procedures were performed of which 10 arterial by passes and one resection graft. Two bypasses were obstructed, the 9 remaining bypasses have a good previous checked clinically and by angiography (or echo-doppler) with a mean follow-up of 14 months.
