A Pilot Study of an Endoscope-Assisted Minimally Invasive Cortical Access System (MICAS) for Chronic Subdural Hematoma Evacuation.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesChronic subdural hematoma (CSDH) is a common neurosurgical condition, particularly in the elderly. While traditional surgical options such as craniotomy and burr hole craniostomy remain prevalent, endoscopic evacuation may offer a minimally invasive approach. This study aimed to evaluate the safety and feasibility of a novel device, the Minimally Invasive Cortical Access System (MICAS), with flexible endoscopic evacuation of CSDH.
methodsA prospective study was conducted from April 2021 to April 2022, enrolling five patients with symptomatic CSDH. Patients underwent endoscopic hematoma evacuation using the MICAS device through a single burr hole. Surgical outcomes and device safety were assessed.
resultsThe MICAS device was successfully used in all five patients, providing stability and maneuverability for the flexible endoscope. A single burr hole of average size 18.2 ± 6.2 mm was used. In four out of five cases, only one burr hole was used, reducing the need for additional incisions. Subdural drains were placed in four patients. Three patients proceeded to have middle meningeal artery embolization (MMAE). The procedure was well tolerated, without notable direct complications.
conclusionThe MICAS device aided in endoscopic evacuation of CSDH, providing safe and effective protection of the cerebral cortex during the flexible endoscopic evacuation. Further studies with a larger sample size are warranted to validate these findings and explore the broader applications of this innovative device.
