ABSTRACT
Severe gravidic toxemia leads to heavy maternal and foetal morbidity and mortality. The purpose of our study is to loosen the factors of bad maternal and foetal prognosis. It's a retrospective study about 100 cases of severe and complicated gravidic toxemia repertorieted in the maternity of Military Hospital of Tunis. Maternal morbidity is dominated by the complications of hypertension and blood disorders. We raised 4 cases of eclampsia, 9 cases of retro placental hematomas and 5 cases of HELLP syndrome. We don't deplore any maternal death. Perinatal mortality is 28,8%. The rate of delay intra-uterine growth was 43,8% and the prematurity 65,9%. The more toxemia appears early during pregnancy more maternal and foetal prognostic is compromised
