ABSTRACT
BACKGROUND:
In an interdisciplinary approach, HepaVision (MEVIS, Bremen), a software tool specifically developed for 3D visualization of the liver, was employed for individual planning of extensive liver resections and evaluation of living-relative donations. So far there is experience with more than 50 biphasic spiral CT examinations.RESULTS:
The spatial relationship of large tumors to crucial hepatic structures, the demonstration and evaluation of anatomic variants regarding vascular supply and the risk stratification of liver failure by volumetric analysis on the basis of portal venous drainage supported precise indication for surgery. Surgical safety is increased by preoperative planning and simulation of necessary vessel reconstructions. By hiding selective areas of portal venous drainage or applying freely selectable clip planes, segmental as well as non-anatomical resections can be simulated and their effects analyzed. The virtual preoperative situs was confirmed intraoperatively in all 17 patients of our study population who underwent segmental liver resection for either a tumor or living-relative donation.
