[Hysterectomy following a cesarean section complicated by hypotonic hemorrhage]. / Gisteréktomiia posle kesareva secheniia, oslozhnennogo gipotonicheskim krovotecheniem.

The features of histories, course of pregnancy and delivery were analyzed in 65 females with hypotonic bleeding developed during cesarean section. The bleeding resulted in uterine extirpation. The factors that predisposed to the abnormality were revealed. Morphological examination of uterine specimens demonstrated that in 95% hypotonic bleedings had been due to profound pathomorphological changes in the myometrium as ones occurred prior to pregnancy and developed during pregnancy and labor. Accordingly, long-term and ineffective treatment of hypotonic bleeding is frequently unfounded as in most cases only ablation of the uterus may be the sole means of hemostasis.
