Objectives: Intraventricular hemorrhage (IVH) caused by thalamic hemorrhage leads to hydrocephalus,
increased intracranial pressure, and reduced levels of consciousness. The aim of this
study was to investigate the efficacy and compare the results of endoscopic surgery
for the evacuation of a thalamic and intraventricular hematoma against those of external
ventricular drainage (EVD) surgery. Materials and Methods: From January 2010 to December 2018, 68 patients with IVH caused by thalamic hemorrhage
were treated in our department. Our study was approved by the Institutional Ethics
Committee. The included patients were randomly divided into an EVD group and an endoscopic
surgery group. The outcome was measured after 3 months using a 30-day mortality rate,
pneumonia onset rate, ventriculoperitoneal (VP) shunt dependency rate, and Glasgow
Outcome Scale (GOS) score. Results: Thirty-eight of the 68 patients were randomly assigned to the endoscopic surgery
group and 30 were assigned to the EVD group. Patients treated with endoscopic surgery
had significantly less drainage dependency on day 30 (P = 0.00014 < 0.00005) in comparison
to those treated with EVD. The difference in the functional outcomes between the two
groups of patients was mainly dependent on the onset of pneumonia and the consciousness
level at the time of admission. The onset rate of aspiration-related pneumonia until
day 30 was 11% in the endoscopic surgery group and 45% in the EVD group. The VP shunt
rates were 27.8% in the endoscopic surgery group and 60% in the EVD group. The endoscopic
surgery group had a significantly lower VP shunt rate compared with the EVD group.
Intracerebral hemorrhage evacuation late was found to be associated with shunt-dependent
rate and hospitalization. Conclusions: Endoscopic surgery was found to be associated with a lower GOS score and lower onset
rates for shunt-dependent hydrocephalus and aspiration-related pneumonia in comparison
to EVD. High evacuation rate was associated with lower shunt-dependent rate and short
hospitalization.
