A Retrospective Study of Puncture and Drainage for Primary Brainstem Hemorrhage With the Assistance of a Surgical Robot.

Abstract

Whether primary brainstem hemorrhage (PBH) should be treated with a conservative treatment or with surgical intervention (such as craniotomy, puncture, and drainage) is still controversial. The aim of this study was to assess the feasibility and safety of puncture and drainage for PBH with the assistance of a surgical robot. A total of 53 patients diagnosed with PBH were included in this study. They were divided into surgical and nonsurgical groups. All patients in the surgical group underwent puncture and drainage of PBH assisted with surgical robots at Beijing Jingmei General Hospital from June 2017 to January 2021. We evaluated this technology with radiographic and clinical results. Postoperative computed tomography showed that all the drainage catheters had been pushed to the target point, which had been designated before the operation. After the operation, the hematoma was reduced by an average of 3.7 mL. None of the patients experienced serious surgery-related complications. Clinical follow-up revealed that 2 patients could not be followed-up, 8 died, and the rest were in disability or in a vegetative state. It may be safe, feasible, and effective to complete the puncture and drainage of PBH with the assistance of a surgical robot. This technique has fewer complications than the traditional puncture method and has high accuracy. It may be more suitable for patients with a hematoma volume of 5 to 10 mL in PBH. The amount of hematoma volume >10 mL may be associated with poor postoperative prognosis. However, high-quality cohorts or case-control studies are needed to verify the effect in this study.
