title: [Effectiveness of multislice computed tomography for evaluating vascular invasion in retroperitoneal tumors].
abstract: The potential of combined application of multislice computed tomography and angiography for evaluation of vascular invasion in retroperitoneal tumors has been assessed. The predictive value of the method was tested by comparing preoperative CT and angiographic data with intraoperative findings on vascular invasion--abdominal part of the aorta and its large branches, inferior vena cava and common iliac veins--in 44 patients; primary tumor--26, recurrent--18, pelvic localization--7, intraperitoneal--37. Thirty-one combined operations were performed. Multislice scans were obtained by using 4 rows of solid-state detectors. For intravenous injections, non-ionic contrasting substance Omniak (loxegol, Amersham, Ireland), 350 mg I/ml was used.
