Dry Field Technique and Ultrasonic Aspirator in Endoscopic Removal of a Hemorrhagic Intraventricular Tumor in a 2-Year-Old Girl.

Abstract

Neuroendoscopic procedures inside the ventricular system always bear the risk for an unexpected intraoperative hemorrhage. Most hemorrhages can be managed by constant irrigation with low- and high-pressure washes. In the other rare cases, the dry field technique may be necessary.^1-5 It requires the aspiration of the entire intraventricular cerebrospinal fluid with the aim of establishing a proper environment for hemostasis. Video 1 illustrates a step-by-step removal of an intraventricular tumor in a 2-year-old girl through an endoscopic technique where the dry field technique was undertaken because of its hemorrhagic nature. Postoperative magnetic resonance imaging showed complete removal of the left frontal tumor infiltration at the level of the left frontal ependyma. The small residual tumor on the left frontal horn was removed using microsurgical technique with another procedure and after achieving complete removal of all visible tumor, the patient was referred to radiotherapy.
