Anticoagulation in Patients with Brain Metastases

Treatment:

  • Anticoagulate in patients with brain tumors and VTE except if risk of ICH is high: i.e.
    • melanoma mets
    • renal cell carcinoma mets
    • choriocarcinoma mets
    • thyroid carcinoma mets
  • treat x 3-6 months; long term if malignant gliomas
  • LMWH recommended versus warfarin
  • If risk of ICH high:
    • IVC filter if significant residual brain mets
    • if mets already removed / treated effectively and medical condition too unstable – anticoagulate

DVT Prophylaxis:

  • do not anticoagulate except in post-operative period
  • use SCDs with post-op LMWH or UFH 12-24 hours after surgery
  • cotninue prophylaxis until ambulation resumed
