Ventriculoatrial Shunts: Review of Technical Aspects and Complications.

Diversion of cerebrospinal fluid is required in many neurosurgical conditions. When a standard ventriculoperitoneal shunt and endoscopic third ventriculostomy are not appropriate options, placement of a ventriculoatrial shunt is a safe, relatively familiar second-line shunting procedure. Herein we reviewed the technical aspects of ventriculoatrial shunt placement using an illustrative case. We focused on the different modalities for inserting and confirming the location of the distal catheter tip. We discussed how to overcome typical difficulties and significant concerns, such as cardiac arrhythmias and venous thrombosis. In addition, we reviewed the current literature for the different complications associated with ventriculoatrial shunt placement.
