Percutaneous choroid plexus coagulation in hydranencephaly.
Percutaneous intracranial endoscopy, performed on 3 infants with hydranencephaly and signs of intracranial hypertension, showed normal choroid plexus and choroid arteries in 2 patients. Transendoscopic coagulation of the arteries and plexus alleviated intracranial hypertension postoperatively. Minimal choroid plexus and no choroid arteries were present in the 3rd patient and coagulation did not alter the clinical course. Computerized tomography scans of the infants with normal choroid plexus demonstrated cerebral tissue in the region of the caudate nucleus; the child with minimal choroid plexus had tissue only in the region of the posterior thalamus.
