Ventriculosagittal sinus shunt placement: technical case report.

Abstract

Determining an appropriate site for distal catheter placement for ventricular shunting for some hydrocephalic patients can be difficult. We describe a simplification of the technique for sagittal sinus shunt placement using a guidewire. A 20-month-old infant with hydrocephalus secondary to Alexander's disease developed erosion of her parieto-occipital ventriculoperitoneal shunt reservoir through an occipital decubitus scalp ulceration. Her hydrocephalus was temporarily treated with a ventriculostomy; however, she developed pneumatosis intestinalis while in the hospital. The patient underwent placement of a ventriculosagittal sinus shunt. The ventricular catheter and shunt valve were placed through a burr hole at Kocher's point, and the distal end of the catheter was placed in the superior sagittal sinus by using the Seldinger technique. Ventriculosagittal sinus shunting may be used as an alternative to traditional methods for patients for whom distal shunt placement is problematic. Our technique has the theoretical advantage of reducing the risks of blood loss or air embolism by not requiring a scalpel incision into the sinus.
