Skull base surgery which sacrifices a major venous pathway can result in postoperative venous infarction of the inferior temporal lobe and/or cerebellum. Preoperative planning can identify the venous structures at risk and prompt the surgeon to modify his approach

A deformable anatomic template (DAT) of the venous pathways has been developed which can be embedded into the patient's preoperative thin section contrast images. It provides the expected normal location of the venous pathways. Each venous structure label can be activated to show text concerning the anatomic variations of all of the veins in the skull base region. If needed, the DAT can be deformed in 3 dimensions to simulate displacement by tumor. All of this information is available in standard axial planes and in conformal reconstructed views. Since the patient's images are labeled, it is possible to evaluate the tumor and the venous drainage in one data set. The relevant literature is summarized for each specific skull base surgery.
