✦ Synopsis

ONE FIGURE

About 10 years ago Lelcsell elaborated a new surgical procedure for the relief of non-communicating hydrocephalus due to obstruction at the aqueduct of Sylvius. Briefly, the method consists of, through the usual suboccipital exposure, easing a soft small rubber catheter up the aqueductal lumen until it is insured, by suction, that the tip has entered the third ventricle, when the catheter is removed. A spiral of metal wire is threaded onto the tip of the catheter, which is then reinserted. When the spiral is in correct position, the catheter is removed leaving the spiral in situ. The catheter used was a No. 7 or 8 CharriGre, i.e., with an outer area of 10 or 13 mm2.
