Abstract
Background : In patients with severe cerebellar hemorrhage or infarction, life-threatening complications may occur. It is generally known that early decompressive craniectomy is superior to craniotomy, but there is no clear guideline for the procedure.
Materials and Methods : From April 2014 to April 2021, patients who underwent suboccipital decompressive craniectomy for cerebellar stroke were treated surgically and followed up. Since September 2020, we have performed craniotomy with obtuse angled partial bone flap in 6 patients. We compared the results of 6 months follow-up in these patients with 9 patients who had previously had only decompressive craniectomy.
Results : There were no deaths during 6 months in either group. Preoperative modified Rankin Scale (mRS) (P = 0.659), 1 month (P = 0.659), 3 months (P = 0.713), and 6 months (P > 0.545) postoperative mRS showed no significant difference between them.
Conclusions : The results were not inferior to those who underwent suboccipital craniotomy with obtuse-angled partial bone flap and those who underwent craniectomy.
