Event Description
|
It was reported that the patient had acute worsening of weakness in their left arm and was relying on their walker to get around.The patient saw their primary care physician (pcp) the next day, who ordered a computed tomography (ct) scan of the patient's head on (b)(6) 2019.That ct scan revealed a right subdural hematoma and the patient was admitted to duke hospital.Originally, the patient presented with fatigue, malaise, and lower extremity weakness from (b)(6) 2020.At that time it was felt that his non specific symptoms were likely related to deconditioning and possible contribution from his interferon therapy.On admission, the patient was hemodynamically stable and conversant.In the emergency room (er) he received a repeat ct of his brain which revealed mixed age (subacute) subdural hemorrhage with midline shift.Neurosurgery was consulted and the patient underwent a right-sided craniotomy with evacuation.The patient's left-sided weakness continued to improve and anticoagulation was restarted 3 days post-op following neurosurgery approval and repeat ct scan.The midline shift remained stable on ct with therapeutic anticoagulation.Warfarin was also restarted for goal international normalized ratio (inr) 1.5-2.The patient was treated with 7 days of keppra for seizure prophylaxis and blood pressure was maintained at goal mean arterial pressure (map) <90 by starting carvedilol.The patient did not tolerate lisinopril due to dizziness.The patient developed left arm weakness later in admission; a repeat ct was unchanged and weakness improved rapidly.Neurology signed off.Physical therapy was consulted and the patient was able to ambulate and was discharged home with pt/ot and tolling walker.The patient's left-sided weakness was much improved by discharge on (b)(6) 2019.
