# Effectiveness of Intracerebral Hemorrhage Aspiration with Catheter Insertion: Impact on Hematoma Volume and Symptom Improvement

## TL;DR

Adding hematoma aspiration during catheter insertion for brain hemorrhage improves recovery and reduces hospital stay.

## Contribution

Demonstrates that intraoperative aspiration during ICH catheter insertion improves motor recovery and shortens hospitalization.

## Key findings

- Patients with aspiration had significantly better motor scores at discharge (p = 0.001).
- Aspiration group was discharged 5 days earlier on average than the catheter-only group.
- Aspiration showed a trend toward improved GCS scores during recovery periods.

## Abstract

Background: Catheter insertion is the most commonly used method for treating intracerebral hemorrhage (ICH). Simultaneous hematoma aspiration allows for faster decompression than catheter insertion alone. Methods: Between March 2020 and Apri1 2024, 49 patients (25 men and 24 women) with ICH underwent ICH catheter insertion. Thirty-two patients (Group A) underwent intraoperative aspiration simultaneously with ICH catheter insertion. The other seventeen patients underwent catheter insertion alone (Group B). Four patients in Group A (12.5%) and two patients in Group B (11.8%) died within one month after surgery. Consequently, a total of 43 patients were included in the final analysis (Group A-1 vs. Group B-1). The Glasgow coma scale (GCS) score and muscle strength of the four extremities in both groups were compared 2 weeks later (first period) and on the date of discharge (second period). Patients in Group A-1 were discharged 5 days earlier than those in Group B-1. (average 49 ± 20 vs. 54 ± 31 days). Results: In Group A, the preoperative ICH volume was 66.2 ± 28.8 mL, and the median aspiration volume was 30 ± 19.6 mL. The preoperative ICH volume was 55.9 ± 22.2 mL in group B. Intraoperative ICH aspiration (Group A-1) significantly improved motor scores during the second period (p = 0.001). It also showed the trend toward improved GCS scores during the first period (p = 0.095) and the second period (p = 0.069). Conclusions: Compared to ICH catheter insertion alone, additional intraoperative ICH aspiration resulted in greater motor improvement at 7 weeks postoperatively (p = 0.004). It also showed a trend toward greater improvement in the GCS scores (p = 0.12).
