PIP: Only 5 cases of cerebrovascular accidents following contraception with progestin alone are to be found in the French literature on the subject. 2 such cases are described in detail in this article; one patient was on Lynestrenol, and another on Norethindrone. The pathogenesis of cerebrovascular accidents under progestin treatment is totally unknown. Patients under this type of contraception should be closely surveilled, both clinically and biologically.
