We investigated the recurrence rate associated with the Aoki method, factors related to recurrence, and the complication risks. Among the cases treated with the Aoki method between June 2007 and December 2020, 383 (431 lesions) for which image analysis and recurrence tracking were possible were included. On the basis of the preoperative patient background (sex, age, history of taking antiplatelet and anticoagulant drugs, preoperative neurological findings, imaging findings (preoperative hematoma volume and hematoma density), surgical details, and postoperative use of concomitant drugs), we retrospectively analyzed the recurrence rate, factors related to recurrence, and complication risk. The recurrence rate was 23.7%, which is within the same range as that of burr-hole hematoma irrigation. Multivariate analysis showed that age and a large preoperative hematoma volume were associated with recurrence. One of the 3 cases with postoperative epidural and 2 of the 3 cases with subdural hematomas required craniotomy. The incidence of complications requiring additional surgery was approximately 1%, which is comparable to that of burr-hole irrigation.

Between 2013 and 2021, 433 patients with subarachnoid hemorrhage who presented within 72 hrs of onset were included.

To address these challenges, we customized the table-top microscope by attaching its scope body and focusing rack to a Visual Electronics Standards Association (San Jose, CA, USA) monitor arm, originally designed for mounting computer monitors. A multipurpose metal plate, known as a \"cheese plate\" and designed for use with photography cameras, was customized to function as an adapter between the microscope and the monitor arm.

To evaluate the modified microscope, its view was compared with that of a traditional microscope using concentric circles and gauze on the slope models. The modified microscope, mounted on the Visual Electronics Standards Association monitor arm, exhibited remarkable flexibility in its working area, height, and angles. The total cost of the modification was approximately $140.
