| Popis: | 12528 Venous Thromboembolism (VTE) is common in patients undergoing treatment for brain tumors. American College of Chest Physicians (ACCP) 2004 consensus conference recommends routine use of intermittent pneumatic compression devices (IPC), unfractionated heparin (UH) or low molecular weight heparin (LMWH) for VTE prophylaxis in these patients. There, however, continues to be a reluctance on using pharmacologic VTE prophylaxis in these patients. The goal of our study was to determine the incidence of VTE in patients with brain tumors treated at a community hospital and the frequency of use of thromboprophylaxis in these patients. Both electronic and paper charts of all patients treated for brain tumors between 1997 and 2003 were reviewed. Follow up data was obtained by contacting physicians caring for these patients. Forty two patients were identified (Anaplastic astrocytoma 10; Glioblastoma multiforme 16; Meningioma 15; oligodendroglioma 1). Twelve patients were treated with various adjuvant chemotherapy regimens. Only 16 patients (38%) received any form of VTE prophylaxis. UH (12) or LMWH (2) were used with or without IPCs or graduated compression stockings. There were eight episodes of symptomatic VTE among 42 patients (19%). These include 6 episodes of deep vein thrombosis (DVT) and two cases of superficial vein thrombosis. Three patients with DVT also had symptomatic pulmonary embolus (PE). All episodes VTE were seen in patients with malignant gliomas yielding a 29% incidence of VTE in patients with malignant gliomas. None of the 15 patients with meningioma had symptomatic VTE. All but one episode of VTE were associated with administration of systemic chemotherapy. Half of these episodes occured more than six weeks after surgical debulking. We conclude that incidence of VTE with malignant brain tumors is high (29%) and the administration of chemotherpy increases this risk. There continues to be underutilization of VTE prophylaxis in these patients at very high risk of VTE. Efforts should be directed at improving the understanding of type and duration of appropiate VTE prophylaxis in patients with brain tumors. No significant financial relationships to disclose. |
