[Sudden death in venous diseases].

We have studied 286 cases of sudden death due to massive pulmonary embolism. In 155 women and 131 men, we made a statistical analysis of the average age, the presence of thrombosis, varices, atherosclerosis, and other complications, and also dietary considerations. We present a detailed observation of a thirty-two year old woman, who died following massive pulmonary embolism, the source of which was thrombosis of the ovarian and pelvic veins. We learned that this woman, who did not smoke, and whose liver was slightly affected, had, for three years, been taking an uninterrupted course of the contraceptive pill Non-Ovlon.
