[Arteritis of the lower limbs in diabetics].

37 cases of diabetic arteritis of lower limbs in diabetic patients were retrospectively studied, from 1988 to 1991. Mean age was 66 years. Masculine predominance was evident with a sex ratio of 1/10. The majority of our patients have consulted at a late stage with trophic disturbance of inferior limbs, indeed 18 patients were seen at the 4th stage. Mortification was observed in 55% cases. Arteriography has allowed to show an elective localization of lesions at the femoralis arteria, profunda femoralis arteria and distal axes. Operative indication was made in 22 patients. Conservative surgery was performed for 50% of the operated patients. Conservative surgery results had been relatively less satisfactory than for others arteritis, particular because of late consultation and the condition of diabetic patients.

[Takayasu disease. Diagnostic criteria and therapeutic procedure].

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.

[Extralobar pulmonary sequestration. A diagnostic pitfall].

The authors report a case of dual malformation: pulmonary (sequestration) and mediastinal (pericardial). This case is original in that clinically and at standard radiography sequestration was mistaken for hydatid cyst. The diagnosis was corrected after anatomico-pathologicale examination of the operative specimen.

[Coronary endarterectomy associated with coronary artery bypass in severe coronary artery disease. 50 cases].

The surgical indications of coronary endarterectomy were defined from a study of 50 cases in which endarterectomy was associated with aorto-coronary bypass surgery. This total represented 6 p. 100 of all the aorto-coronary bypass operations performed in the same period. Coronary endarterectomy was performed "on principal" for the right coronary artery, and "of necessity" for the left anterior descending artery. The special techniques of endarterectomy on the left anterior descending artery are described. Endarterectomy does not increase the operative risk and enables revascularisation of vessels unsuitable for bypass surgery. 85 p. 100 patients are asymptomatic with an average follow up period of 2 years after endarterectomy and aorto-coronary bypass graft of the right coronary artery.

[Mitral valve insufficiency due to ballooning. A surgical series of 70 cases].

The authors report 70 cases of mitral regurgitation due to ballooning. For the surgeon this is the most frequent cause of degenerative mitral regurgitation in patients around 60-years-old. The aetiology still remains unknown. There are two opposing theories--the congenital and the acquired. The appearances at operation are characteristic--a localised or diffuse ballooning of one or both cusps with elongation of the chordae attached to the ballooned portion. Two histological features are noted--myxomatous degeneration of the cusp and the absence of any inflammatory process. Ballooning may be asymptomatic and bening for a long time before evolving progressively or suddenly into important mitral regurgitation. The pre-operative diagnosis is aided by left ventricular angiography and echocardiography. Surgical treatment, guided by the findings at operation, usually involves mitral valve replacement or, less frequently, mitral valve repair.
