Preventing Distal Catheter Obstruction in Laparoscopic Ventriculoperitoneal Shunt Placement in Adults: The "Falciform Technique".

摘要: Abstract Background: Distal obstruction of ventriculoperitoneal (VP) shunts is a major problem in the treatment hydrocephalus. To avoid this complication, we describe simple method using falciform ligament to place and hold distal catheter right subdiaphragmatic space, preventing migration obstruction. Materials Methods: We retrospectively collected data all VP shunt insertion revision for adults with idiopathic normal-pressure hydrocephalus between November 2011 September 2013. All these were done “falciform technique,” portion performed laparoscopically. No exclusion criteria applied. A neurosurgeon laparoscopic surgeon involved each case. The was used tether above liver, tip reaching hepatic flexure allow drainage directly into paracolic gutter. Baseline, operative, postoperative c...
