Our study is based on a retrospective analysis of 18 cases of fibroma and pregnancy association in the maternity of CHU HASSAN II Fez MOROCCO over a period from 2014 to 2018 and whose purpose is to study maternal and fetal morbidity during fibroid association and pregnancy and to remind the therapeutic attitude vis-à-vis fibroids during pregnancy. The frequency of this association is 0.37%. It occurs mainly in women older than 30 years. Primiparous most often. In 61, 11% the diagnosis of fibroma was made for the first time during the pregnancy. Aseptic necrobiosis relatively frequent, accounting for 22.22% of all complications, it has evolved well under medical treatment. Although dystocic presentations, premature rupture of membranes, miscarriages and threats of premature delivery are frequently encountered, pregnancy is in most cases around the term. The delivery took place in 47.05% by Caesarean. The maternal and fetal prognosis is excellent. Treatment remains based on abstinence and regular clinical and ultrasound monitoring. Myomectomy during pregnancy is to be reserved for the torsion of pedicled fibroma and necrobiosis resistant to medical treatment. The association fibroid and pregnancy is not rare, the complications are frequent hence its membership in the lot of high-risk pregnancies. Early detection of complications and prevention of delivery hemorrhage would reduce maternal and fetal morbidity.
