Long-term follow-up showed 75.6% of patients achieved favorable clinical outcomes over a median duration of 51 months.
Key risk factors for complications included GCS grade ≤12 before procedures and age ≥60, alongside other medical conditions.
Cumulative survival rates were high at 1, 3, and 5 years, reaching up to 95.4%, indicating the potential effectiveness of the treatment.
