Safe and time-saving treatment method for acute cerebellar infarction: Navigation-guided burr-hole aspiration - 6-years single center experience.

Abstract

Objective: While patients with medically intractable acute cerebellar infarction typically undergo suboccipital craniectomy and removal of the infarcted tissue, this procedure is associated with long operating times and postoperative complications. This study aimed to investigate the effectiveness of minimally invasive navigationguided burr hole aspiration surgery for the treatment of acute cerebellar infarction.

Methods: Between January 2015 and December 2021, 14 patients with acute cerebellar infarction, who underwent navigation-guided burr hole aspiration surgery, were enrolled in this study.

Results: The preoperative mean Glasgow Coma Scale (GCS) score was 12.7, and the postoperative mean GCS score was 14.3. The mean infarction volume was 34.3 cc at admission and 23.5 cc immediately following surgery. Seven days after surgery, the mean infarction volume was 15.6 cc. There were no surgery-related complications during the 6-month follow-up period and no evidence of clinical deterioration. The mean operation time from skin incision to catheter insertion was 28 min, with approximately an additional 13 min for extra-ventricular drainage. The mean Glasgow Outcome Scale score after 6 months was 4.8.

Conclusions: Navigation-guided burr hole aspiration surgery is less time-consuming and invasive than conventional craniectomy, and is a safe and effective treatment option for acute cerebellar infarction in selected cases, with no surgery-related complication.
