Just now, a patient with subacute SDH who was treated for a full month was discharged. The patient had a hematoma of at least 120 ml with septation and midline shift of 1 cm. Because of long-term oral anticoagulant aspirin and other vasodilators, the platelet count was low, and the value of arachidonic acid aggregation assay was less than 1/5 of the lower limit of normal, with the consent of the patient’s family, the patient was treated with conservative treatment based on atorvastatin, and the patient’s hematoma changes were continuously observed with head MRI, which was reviewed 4 days, 1 week, 2 weeks, 3 weeks, and 1 month, respectively, after the administration of drugs. After reviewing the head MRI at 4 days, 1 week, 2 weeks, 3 weeks and the first month, we were surprised to see that such a huge subacute subdural hematoma with segregation had gradually shrunk from 120 ml to 40 ml within one month, and the patient was discharged from the hospital for recuperation after her symptoms were basically completely relieved! Our new therapy seems to have the potential to further improve the efficacy of atorvastatin. Stay tuned. I will post the precious SDH images of this series when I have the chance to share them with you.
