Retrospective analysis of the surgical management of spontaneous supratentorial intracerebral hemorrhage: A single-center study.

Background: Intracerebral hemorrhage (ICH) remains a devastating disease with high morbidity and mortality. The mortality rate ranges from 40% at 1 month to 54% at 1 year, and only 12%-39% achieve good outcomes and functional independence. The current management guidelines for spontaneous supratentorial ICH are still controversial.

Objective: Patients who presented with ICH and underwent craniotomy with hematoma evacuation or minimal procedures from January 2016 to May 2020 were included in the analysis. Several clinical, radiological, and surgical variables were collected to identify the variables most likely related to lower mortality and better functional outcomes.

Results: A total of 87 patients presented with HMC with ICH from January 2016 to May 2020. The mean age was 44.7 (42.2-47.2) years. There were 76 male (87.4%)/11 female (12.6%) patients, which reflect the population distribution in Qatar, which is mainly male predominant. Although Qatar is mainly a Middle-Eastern country, the ethnic distribution of patients was mainly of South Asian and Indian (60.9%) and Far-Eastern (20.7%) ethnicities because of diversity. The mean baseline Glasgow coma scale (GCS) was 8.2+/ - 3.7. The mean baseline functional independence measure (FIM) score was 59.4+/ - 36.7. Most hematomas were located in the basal ganglia (79.3%%). Baseline characteristics based on long-term outcomes are summarized in Table 1. The following variables were correlated with poor outcome: low GCS on postoperative day 1 (P = 0.06), low FIM score (P = 0.006), ICH location (P = 0.04), distance of the closest point to the surface (P = 0.009), and presence of uncal herniation (P = 0.04). The baseline characteristics based on mortality are outlined in Table 2. The following variables were correlated with mortality: diabetes mellitus (P = 0.02), baseline GCS (P = 0.04), GCS on postoperative day 1 (P = 0.002), unequal pupils (P = 0.05), and postoperative midline shift (P = 0.001).

Conclusion: The preoperative clinical neurological status as well as mass effect (uncal herniation and midline shift) can be determinants of functional outcome and mortality. A deeper hematoma may result in poor functional outcome because of more surgical damage in functional brain tissues. Thus, the goal of surgery in spontaneous supratentorial ICH is to reduce mortality, but no evidence support that it can improve functional outcome. Although our findings are interesting, more prospective studies with a larger sample size are needed to confirm our results.
