[Association of Takayasu's arteritis, pregnancy and Still's disease].

Two pregnant patients presented with Takayasu's disease predominating in the major branches of the aorta. There was no extention below the diaphragm and no complications. One of the patients had Still's disease which is a predominantly cutaneous form without chronic arthritis. Both pregnancies were uneventful excepting dysgravidia in one case. Two eutrophic infants were born at term. The risk of Takayasu's arteritis associated with pregnancy, as reported in the literature, is mainly due to the consequences of arterial hypertension with pre-eclampsia (60%), heart failure and cerebral vascular events (5%). The major fetal risk is in utero death (2 to 5%), but intra-uterine growth retardation is more frequent (18%). The risk is greatest during the third trimester and during the perinatal period. Fetal involvement is greatest in sever cases and in those treated late. Prevention is based on the initial work-up to identify the disease and possible complications, programming pregnancies and increasing surveillance during periods of risk, defining the delivery route with cesarean section reserved for complications of arteritis (30%), and planned labour with instrumental extraction and epidural anaesthesia with control of the blood pressure. Still's disease has no particular consequence on pregnancy, although sequellae of chronic arthritis of the pelvis may have an impact on obstetrical technique. An association with Takayasu's disease is rare with only one case being reported in the literature; aetiopathology remains unknown.
