Manajemen Anestesi pada Pasien dengan Tumor Regio Pineal yang Menjalani Kraniotomi Pengangkatan Tumor dengan Posisi Duduk

Abstract

Incidence of pineal regio tumor is 0.4-1% of intracranial tumors. Its location which is buried between two cerebral hemispheres, close to brainstem and hypothalamus become a difficult challenge for the neurosurgeon. Surgery with supracerebellar approach in sitting position is the best method to access the lesion. Sitting position also facilitates the optimal visual field with minimal retractions. However, for anesthesiologist, sitting position is challenging since it has its own complexities during positioning the patient and the risk of complications. Venous air embolism is one of the main concern and if not detected early and treated appropriately would leads to cardiovascular collapse instantly. This is a case of a 38-year-old male with chief complaint of severe headache and blurred vision started 4 months before admission. The Magnetic Resonance Imaging showed a pineal region tumor with perifocal edema, without midline deviation. The patient underwent craniotomy tumor removal with sitting position. The procedure lasted for 10 hours and uneventful. The principle of ABCDE neuroanesthesia, sitting position and its implications, and difficult tumor location are some anesthesia considerations for this patient. A thorough preoperative evaluation, good communication and coordination between surgery and anesthesia team are needed for a smooth uneventful procedure performed in sitting position.
