Abstract
Background
The aim of this study was to compare the therapeutic effects of non-navigated freehand minimally invasive aspiration and conservative medical care in patients with deep supratentorial intracerebral hemorrhage (ICH).
Methods
We analyzed data from a prospective multicenter cohort study. Propensity score matching was performed to adjust for possible confounding factors. A total of 122 patients with first-onset deep supratentorial ICH with a volume ≥ 20 ml were enrolled. All patients were followed up at 30 days, 90 days, and 1 year. The mortality rate, functional outcomes, complications, and treatment costs were compared between the two groups.
Results
After propensity score matching, 122 patients with a mean age of 56.0 years were included, 77.9% of whom were male. The median ICH volumes were 45.5 ml in the surgery group and 48.0 ml in the conservative group. The mortality rate at 30 days was significantly lower in the surgery group than in the conservative group (P = 0.0127). There were no significant differences in functional outcomes at the 90-day and 1-year follow-ups between the two groups (P > 0.05). There was no significant difference in complications, including recurrent bleeding (6.6% vs. 4.9%), pulmonary infection (57.4% vs. 41.0%), deep venous thrombosis (9.8% vs. 11.5%), heart failure (1.6% vs. 6.6%), and cerebral infarction (4.9% vs. 3.3%), between the two groups.
Discussion
For deep supratentorial ICH, non-navigated freehand minimally invasive aspiration was safe and reduced short-term mortality but did not effectively improve long-term functional outcomes.
