The truths behind the statistics of surgical treatment for hypertensive brainstem hemorrhage in China: a review.

Hypertensive brainstem hemorrhage (HBSH) is of high morbidity and mortality rate. But many clinical studies were written in Chinese and had not been reviewed. A systemic review of Chinese clinical studies for HBSH was performed. A systemic literature search in PubMed, Web of Science, China National Knowledge Infrastructure, and Weipu database and Wanfang database up to March 2020 was performed. Clinical control studies including a surgical evacuation (SE) group and a conservative management (CM) group were included. The clinical outcome and mortality rate were compared. Ten cohort studies were included, involving 944 participants (304 in the SE group and 640 in the CM group). All included patients were comatose, with the average age ranged from 45 to 65 years old. Among five studies using mRS or GOS as outcome score, a total of 16.6% (89/535) of patients achieve self-maintenance with minor disabilities, including 26.8% (34/127) in the SE group and 13.5% (55/408) in the CM group. The overall mortality rate in the SE group was 27.6%, ranged from 9.3 to 60% among different studies. The overall mortality rate in the CM group was 60.6%, ranged from 18.5 to 100.0%. Elder and comatose HBSH patients are not contraindicated for surgery. The review showed that this group of patients obtained a better outcome and lower mortality rate after surgical treatment. The quality of included studies was relatively low, but a high-level clinical study on HBSH is of great difficulty, as both clinicians and patients faced various sociological issues rather than pure medical problems.
