[Preoperative roentgeno-endovascular occlusion of the branches of the hepatic artery in focal lesions of the liver].

Preoperative roentgenendovascular occlusion of branches of the hepatic artery was performed in 22 patients with local alterations of the liver. The occlusion was fulfilled with artificial emboli from hydrogel of a spherical and cylindrical form. Metallic spirals were additionally introduced into the artery lumen to 13 patients. All the patients were operated upon 1-10 days after REO (hemihepatectomy or subsegmentary resection of the liver). When using the method of REO the intraoperative blood loss was several times less, not more than 0.35 l.
