An embolized-cryoablation method for treating a tumor of an organ is provided. The method includes inserting a catheter in a vascular pathway connected to a target region adjacent the tumor, and advancing the catheter through the vascular pathway to place a distal end portion of the catheter in the target region; injecting a liquid embolization material through the catheter into the target region; removing the catheter through the vascular pathway from the organ; inserting a cryoprobe laparoscopically into the target region, and placing a distal end portion of the cryoprobe within the target region; delivering a cryogen into and circulating the cryogen inside the cryoprobe for a period of time, thereby providing a cryotreatment to the target region of the organ. The combined embolization-cryoablation treatment reduces bleeding and enhances cell death, necrosis, or apoptosis in the tumor tissue.
