Venous thromboembolic complications with and without intermittent intraoperative and postoperative pneumatic compression in patients with glioblastoma multiforme using intraoperative magnetic resonance imaging. A retrospective study.

Our results demonstrate, that the surgical intervention and the subsequent patient immobilization, as well as the thromboprophylactic techniques used have a relatively low influence on the occurrence of thromboembolic complications than we expected. Our findings might be attributed to the overall low number of these complications in a glioblastoma multiforme patient population expected to be at a high risk for coagulopathy. In other words, in order to produce statistically significant results, we would need to increase the patient cohort. By doing so we may better detect a positive therapeutic effect. Alternatively, because of the multitude of possible complex risk-factors leading to coagulopathy in a glioblastoma patient population it might be the case that IPC has little or no effect and that there is a different underlying mechanism responsible for the observed coagulopathy.
