Abstract 1122‐000216: Evacuation of Bilateral Intracerebral Hemorrhages Using a Novel Disposable Surgiscopic System: A Case Report

Introduction : Patients presenting with intracerebral hemorrhage (ICH) face higher rates of morbidity and mortality than other stroke patients. Currently, these patients are managed by surgical intervention and decompression or medical management, depending on categorization of the hemorrhage. Simultaneous, multifocal hemorrhages are a rare presentation of ICH that portend a worse prognosis. Here we report the treatment of bilateral simultaneous ICHs in a young patient with diagnostic cerebral angiography, biopsy, and bilateral minimally invasive surgiscopic ICH evacuation in a single procedure. Methods : The patient was a young female who presented to an outside hospital after two days of progressively worsening headaches and vomiting. Her medical history was significant for systemic lupus erythematosus (SLE), hypertension, chronic migraines, and opioid use disorder. In the emergency department, her mental status deteriorated, and she was intubated. Computed tomography (CT) scan was performed and showed a right parietal 43.3 cc ICH and a left parietal 38.7 cc ICH. MR angiogram and venogram showed no evidence of vascular malformations but were suggestive of potential cerebral venous sinus thrombosis. Upon arrival, the patient remained intubated but was able to open her eyes, follow commands, and respond to stimulation. The patient was brought to the angiosuite for diagnostic cerebral angiography which revealed diffuse intermittent arterial narrowing suggestive of vasculitis and patent venous sinuses. The patient was then positioned in the prone position and bilateral parietal 1.5 cm craniectomies were performed. Surgiscopic evacuation was performed sequentially using stereotactic navigation to access and evacuate each clot. A right parietal brain biopsy was performed at the minimally invasive cortical access point. Results : Active bleeding was encountered in both hematoma sites and was treated with a combination of irrigation and monopolar cautery transmitted through the Aurora Evacuator. After complete evacuation of the hematomas on both sides, an intraoperative conebeam CT was performed, demonstrating good right‐sided evacuation and resident left‐sided hematoma. Additional evacuation was performed on the left side and repeat conebeam CT demonstrated good bilateral evacuation. CT head on post operative day 1 showed 97.7% right‐sided evacuation and 81.5% left‐sided evacuation. The patient was treated with steroids for presumed vasculitis given the angiographic findings, which was later supported by the results of the brain biopsy. The patient made a good recovery and was discharged from the hospital alert and oriented, with CN II‐XII grossly intact, no focal deficits, and 5/5 strength in all extremities. Conclusions : Minimally invasive ICH evacuation can be performed in the angiosuite for ICH‐associated with vasculitis and even multifocal ICH when appropriate. Performing the procedure in the angiosuite permits completion of the diagnostic cerebral angiogram, brain biopsy, and hematoma evacuation at the same time, accelerating time to treatment for a patient with severe, symptomatic vasculitis.
