Objective: assessment of safety and efficiency of application of the method of the distal and proximal embolization of the right branch of a portal vein using an occluder for preventive increase of the small future remaining liver amount in case of the planned resection. Material and methods. In the Burnazyan Federal Medical Biophysical Center that method was used in two cases: metastasises of bladder cancer in one case and of colorectal cancer in second case. Patients were males aged 57 and 64. Measuring the amount of future remaining liver volume was carried out with the CT-volumetry. Portal vein embolization of the right branch was carried out by transhepatic ipsilateral access using polyvinyl alcohol particles and occluder AVP II. Results. As a result in both cases the gain (9 and 24%), sufficient for performance of a resection, of the remaining liver volume was noted; the progression of the tumor process and periop-erative complications were not observed. Conclusion. Distal and proximal preoperative portal vein embolization is an effective and promising method, allowing surgeons to increase the number of operable patients and reduce the risk of postoperative liver failure.
