[Status of blood coagulation and various background endocrine indices in patients with basal meningiomas during pre- and postoperative periods].

The condition of blood coagulation activity and the indices of the endocrine background were studied in patients with tumors of prevalently basal localization which caused a direct effect on the central regulating centers. Thirty patients with basal and medially located meningiomas were examined in the pre- and postoperative periods. Before the operation most patients had clinical signs of endocrine-metabolic disorders, often in the presence of an increased content of ACTH and cortisol in the blood. Blood coagulation was disturbed in the majority of patients, mainly due to increased activity of the blood coagulation system. In the postoperative period, blood coagulation activity in 24 of 30 patients was increased or showed a tendency to increase in the presence of elevated blood ACTH content while processes of fibrinolysis were inhibited, which substantiates the necessity for anticoagulant therapy when large doses of glucocorticoids are used.
