[Intracranial and intraspinal hemorrhages in treatment with coumarin derivatives. Catamnesis of 63 cases between 1978 and 1986].

From 1978-1986, 63 patients (48-79 years) under coumarin derivatives had to be hospitalized neurosurgically because of intracranial or intraspinal bleedings. This corresponds to a twelvefold increased risk compared to the untreated people. The male/female ratio was 1.5. At the time of the bleeding there was no true indication for anticoagulation in at least 60% of the patients. 80% with coma on admission died. Only for 2/7 with an intraspinal hemorrhage the outcome was better than paraplegic. Women proved to have a better chance of survival. There is a need for more concise indications for chronic anticoagulation.
