Free-Hand Bedside Catheter Evacuation of Cerebellar Hemorrhage

Abstract

Object: Cerebellar hemorrhage is a life-threatening condition that requires immediate surgical intervention. Open craniectomy, hemorrhage evacuation and posterior fossa decompression is the treatment of choice. Patients with aspirin antithrombotic medication, however, face an increased risk of postoperative rebleeding, because it is impossible to normalize blood coagulation in time. To sufficiently treat these patients, we have developed a minimally-invasive, free-hand, bedside catheter evacuation technique.

Clinical Presentation: In a retrospective analysis, two patients with a mean age of 68 years and antithrombotic aspirin medication with cerebellar hemorrhage were treated. On admission, mean hemorrhage volume was 30.25 mL or 3.7×4.75×3.03 cm, mean GCS was 7.5, initial aspiration drained a mean 24 mL of blood. After a mean of 2.5 days of urokinase lysis, mean hemorrhage volume was 3.7 mL or 2.25×2.0×1.15 cm and mean EGOS on discharge was 4.5. After a mean follow-up of 408 days, the mean EGOS was 5.5, and both patients were alive.

Conclusion: We conclude from these data that, in selected cases, bedside catheter placement and consequent urokinase lysis is a successful way to drain posterior fossa hemorrhage. However, experience in catheter positioning is crucial and the technique therefore should only be performed by experienced neurosurgeons.
