The treatment of vascular malformations requires the placement of needles in anatomically non-well defined, pathological vessels that can be as small as 1 mm. The procedure currently relies primarily on two-dimensional fluoroscopic and ultrasonic images for guidance. We hypothesize that the combination of stereotactic image guidance with existing targeting methods can achieve a reliable and fast placement of the needle while resulting in low radiation exposure and contrast agent dosages. We herein present an evaluation of the integration of a stereotactic image guidance system into the workflow for the treatment of these malformations in a clinical pilot study. Specifically, we evaluated the supported placement of percutaneous needles for the treatment of the malformations. Preliminary results of the first four patients are presented.
