Abstract

Introduction: Chronic subdural hematoma accounts for 10% of all intracranial hemorrhages and has an increased incidence in the elderly. The evacuator trephine is the most commonly used surgical technique, but its recurrence range is high.

Objective: To present the surgical technique of craniotomy with partial membranectomy

Methods: This is a descriptive study carried out by the Neurosurgery Service of Manuel Ascunce Domenech University Hospital from 2022 to 2024, which included 25 patients diagnosed with chronic subdural hematoma and visible membranes on tomography, who underwent craniotomy with partial membranectomy.

Results: Patients with 60 years of age and more, of the male sex predominated. 40 % of the hematomas were left, 32 % bilateral and 72 % of the cases discharged alive. The technical particularities of osteoplastic craniotomy are discussed through four trephine equidistant to 4 cm, centered on the site of greater thickness and complexity of the hematoma oriented by tomography. Durotomy was performed, followed by opening and resection of the parietal membrane with bipopolar coagulation

Conclusions: Craniotomy with partial membranectomy should be performed in patients with chronic subdural hematomas and visceral membrane visible on tomography. Through the proposed dimensions, the hematoma can be evacuated, its membranes treated effectively and brain re-expansion can be evaluated.
