ENDOSCOPIC COAGULATION OF THE CHOROID PLEXUS
In 1934 an operation for the relief of hydrocephalus was described.1 It consisted in destruction of the choroid plexuses of the lateral ventricles by means of a special operating endoscope. The principle involved had been suggested many years before2 and has apparently been utilized occasionally by various surgeons,3 but at that time no other series of case reports had been published. Since then, the number of patients operated on has been increased4; Scarff, who independently developed a somewhat similar instrument, reported five cases.5 The authors cited described the operative technic and discussed the respective merits of various types of instruments.
STATISTICS ON OPERATIONS
The present report is based on twenty-six cases of infantile hydrocephalus in which the patients were subjected to the operation. Forty-nine operations were performed, as the procedure was carried out in two or more sessions in
