Overview
The role of surgery for most patients with spontaneous ICH remains controversial. The theoretical rationale for hematoma evacuation revolves around the concepts of preventing herniation, reducing ICP, and decreasing the pathophysiological impact of the hematoma on surrounding tissue by decreasing mass effect or the cellular toxicity of blood products. Additionally, the current recommendations do not apply to intracranial hemorrhage caused by trauma or underlying structural lesions such as aneurysms and arteriovenous malformations, because these patients were not included in the described ICH surgery trials.
Surgery
Timing of surgery for ICH remains controversial. Randomized prospective trials to date have reported on a wide time frame for surgery that ranges from 4 to 96 hours after symptom onset. Ultra-early craniotomy (within 4 hours from ictus) was associated with an increased risk of rebleeding in a study that involved 24 patients.
Craniotomy for supratentorial hemorrhage
Early hematoma evacuation has not been shown to be beneficial in the 2 latest randomized trials, and it is still unclarified whether surgery may benefit specific groups of patients with supratentorial ICH.
Craniotomy for posterior fossa hemorrhage
Because of the narrow confines of the posterior fossa, obstructive hydrocephalus and local mass effect on the brainstem can result in rapid deterioration of the patient with cerebellar hemorrhage.
- Surgical decompression in patients whom cerebellar hemorrhage is associated with brainstem compression or hydrocephalus or patients with cerebellar hemorrhages >3 cm in diameteris are associated with good outcomes.
- Controlling ICP via means other than hematoma evacuation, such as VC insertion alone, is considered insufficient, is not recommended, and may actually be harmfu.239
- Evacuation of brainstem hemorrhages may be harmful in many cases
Minimally invasive surgical evacuation of ICH
Several recent randomized studies have shown minimally invasive aspiration associated with better outcomes with less invasive approaches compared to standard craniotomies.
