Abstract
Endoscopic third ventriculostomy is considered a safe technique for the treatment
of obstructive hydrocephalus. However, the literature contains several reports of
complications related to this procedure. We describe a case of chronic subdural hematoma
(CSDH) after ETV, which required surgical evacuation, in a 69-year-old male patient
completely asymptomatic up to the control MRI four weeks after the operation. We believe
this unusual complication could result from the ICP changes caused by ETV. In our
opinion, successful ETV gives a boost to CSF absorption, and overdrainage may evolve
also in endoscopic treatment of obstructive hydrocephalus. This situation could be
the starting point of the subdural collection. We review the literature and discuss
the causes that may lead to CSDH after ETV procedure.
Key words
Chronic subdural hematoma - endoscopy - third ventriculostomy - overdrainage
