“…This device, invented by the French anatomist/surgeon Claude-Nicolas Le Cat (1700–1768), has not previously been recognised in the literature, and only few authors have cited this case report from 1744 as the first documentation of ventricular puncture/drainage in the history of treatment of congenital hydrocephalus [5, 6], others only refer to the citations [7, 8, 9]. Most modern reviewers of the history of the (surgical) treatment of hydrocephalus do not mention the published procedure at all [10, 11, 12, 13, 14, 15]. However, in our opinion, Le Cat deserves full credit for the first description of a device for external ventricular tap in a desperate case of congenital hydrocephalus, during which he left a fixed drainage canula in place for 5 days.…”
