Half-Dose Anticoagulation for Venous Thromboembolism and Phlegmasia Cerulea Dolens in a Patient With Recurrent Subdural Hematoma.

Anticoagulation for venous thromboembolism (VTE) in patients with recurrent subdural hematoma (SDH) is challenging. It becomes even more challenging when the patient develops phlegmasia cerulea dolens (PCD). We present a 66-year-old female with a recent history of recurrent SDH who received half-dose heparin therapy for VTE and PCD. The patient had improvement of dyspnea and resolution of PCD after two days of treatment. She was discharged with half-dose enoxaparin. At her one-month follow-up, there was no evidence of new SDH or progression of VTE. Half-dose anticoagulation therapy should be considered in patients with recurrent SDH when anticoagulation is inevitable.
