[Takayasu-type arteriopathies. Apropos of 4 cases observed in Ivory Coast]. / Les artériopathies de type Takayashu. A propos de quatre cas observés en Côte-d'Ivoire.

Report of 4 cases of Takayasu type arteriopathy observed in the internal medicine department of Treichville Hospital (Abidjan University). During a one year study the prevalence appeared high in African women: 0.4 p. 100 of all female admittances; 1.2 of the female patients under 35 years; 2 p. 100 of the females admitted for cardiovascular disease. Diagnosis criteria are studied: epidemiological criteria (young age, with a mean value of 21 years); clinical and biological criteria: high blood pressure associated with the absence of one or several arterial peripheric pulses and the presence of one or several arterial murmurs; biological criteria which are negative in the four cases this negativity indicating an occlusive phase. Aortography is the main diagnosis support, showing the situation of the lesions, permitting a topographic classification and giving the mechanisms of blood hypertension with, sometimes, a therapeutic consequence. In one case an inflammatory condition of the aorta has been observed at the media adventitia junction. A systematic study of etiology has brought no evidence of another possible diagnosis. Pathogenic role of tuberculosis is suspected but had not yet been demonstrated.

[Pheochromocytoma in black African. Five cases whose three ectopic. Review of literature: thirty-three cases (author's transl)]. / Phéochromocytomes chez le noir africain. Cinq cas dont trois ectopiques. Revue de la littérature: trente-trois observations.

The authors report five cases of pheochromocytoma observed in black African people, followed in the Hospital University Center of Treichville. Three of these pheochromocytoma were in ectopic location. In connection with these observations, the authors review the African literature, regrouping 33 cases, which allows to define the principal aspects of the disease in black African patients. The over morbidity amongst the female patient, the frequent discovery during pregnancy or even at the onset of labour, the frequency ectopic localization are quite original characteristics.

[Arterial thrombosis of the femoro-popliteal axis. An exceptional case of vascular complication by exostosis (author's transl)]. / Thrombose artérielle fémoro-poplitée un case exceptionnel de complication vasculaire par exostose.

The authors report an exceptional case of arterial thrombosis of the femoro-popliteal axis, caused by a bony exostosis of the femur. It was a man of 48 years, presenting with sub-acute ischemia of the left lower limb. The different examinations showed an extensive femoro-popliteal artery thrombosis centered by a bony exostosis of the inferior third of the femur. The patient was successfully operated upon with resection of the exostosis and saphenous vein femoro-popliteal by-pass. A review of the literature shows the rarity of vascular complication of exostosis and particularly of thrombosis, previously reported only 4 times. An explanation of the mechanism involves the repeated trauma on the artery in this narrow region and the possibility of superimposed atheroma.
