Abstract:
Background: Hemostasis disorders in form of increased bleeding or thrombosis are a serious problem for the treatment of neurosurgical tumor patients. The study analyses several parameters which are of influence to coagulation and fibrinolysis, and relates them to each type of brain tumor.
Material and methods: The prospective study peri-operatively examined 100 neurosurgical brain tumor patients for coagulation disorders. The examinations took place on the pre-operative day, on the day of the operation and on the third and finally seventh day after the surgery. The findings have been put in correlation to the kind of brain tunor, the age and the sex of the patient, and to the treatment.
Findings: The majority of the patients shared one common feature. The intra-operative volume therapy caused hemoilution and resulted, post-operatively, in a prolonged bleeding time. This inceased bleeding time correlated with changes in regard to plasmatic coagulation factors. On the third post-operative day, most patients had normalized coagulation parameters. From the third day to the seventh day however, some patients displayed an exceeding coagulation with increased dispostion to thrombosis.
Result: Neurosurgical tumor patients have due to the amount of risk factors a high predispostion rate for thrombembolic compications. Aimed pre-operative screenings and post-operative controls of the parameters suggested in this study allow to indicate hemostatic disorders at an early stage. After assessing these parameters in context of other symptoms it is possible to conceive and apply an adequat therapy concept to improve the prognosis of the patient.
