Management of Chronic Subdural Hematoma in Patients with intractable Thrombocytopenia.

BACKGROUND Currently, the platelet count threshold for platelet transfusion that is commonly used prior to surgical evacuation of CSDH is 100,000 per microliter. This study is done to show the outcome of the surgical evacuation of CSDH in patients with intractable thrombocytopenia (platelet count which did not reach 100,000 per microliter after platelet transfusions). MATERIAL AND METHODS This study retrospectively reviewed the admitted patients with symptomatic CSDH and intractable thrombocytopenia in our university hospitals from January 2007 to January 2016. RESULTS Forty-one patients were included in this study. No incidence of intraoperative or postoperative acute bleeding in any patient. CONCLUSION Evacuation of CSDH in thrombocytopenic patients, without reaching a platelet count of 100,000 per microliter, is an option. Further randomized controlled trials are needed to determine the correct platelet count threshold prior to evacuation of CSDH.
