Patients may benefit with surgery:
 Basal ganglia or thalamic
 GCS > 4
 Supratentorial ICH > 30 cc (Level IV-V, Grade C)

Surgery for pts in coma but not herniated –
• hematoma is located on the BG,cerebellum
• family is willing to accept the consequences
of persistent vegetative state / irreversible
coma
• Goal is reduction of mortality (survival)

Patient selection & surgical technique DOES MATTER !
Endoscopic Evacuation
• Selection criteria
Thalamic hemorrhage with IVH due to hypertension
GCS 12 and below
Surgery performed within 24 hours
Excluded are patients who were comatose, on
antiplatelet/anticoagulants,medical conditions
Mariano et al
St. Luke’s Medical Center
Surgical Technique
Frontal Burr hole (ipsilateral or
contralateral)
Rigid endoscopes
Lactated Ringer’s solution as
irrigation
Suction/Irrigation
Clear up frontal horn first, look for
landmarks(foramen of Munro,choroid
plexus, or septum pellucidum)
Hemostasis by washing and cautery
Intraventricular ICP probe inserted
Continuous EVD
CLOT
THALAMIC SUBSTRATE
Preliminary Results of Endoscopy for TH
Good ICP control, EVD removed by day 3 postop
14/15 patients improvement in
level of consciousness, 1 got worse (rebleed),
no mortality
The hospital stay was 30% shorter and
recovery was faster than previously
treated patients (range 1 to 4 weeks)
Only I patient needed a permanent VP shunt
