title: [Arterial redistribution to prevent hepatic arterial occlusion and gastric ulcer using hepatic arterial infusion chemotherapy with percutaneous catheterization].
abstract: Clinical usefulness of arterial redistribution using steel coils to prevent hepatic arterial occlusion and gastric ulcer was compared with the conventional method. Fifty-two patients with liver malignancies were inserted with steel coils into the common hepatic artery after percutaneous hepatic catheterization (CHA-coil) to prevent hepatic arterial occlusion. The tip of the indwelling catheter was fixed to the vascular wall, and the contact area between the catheter and blood into the liver became smaller. Fifty-nine other patients were inserted with steel coils into the right gastric artery (RGA-coil) to prevent gastric ulcer. The CHA-coil succeeded in 84% of the patients, and hepatic arterial occlusion occurred in only 4% of these patients. The RGA-coil succeeded in 88%, and gastric ulcer occurred in 2%. The rates of hepatic arterial occlusion (4%) and gastric ulcer (2%) were much decreased in comparison with 25% and 16%, respectively, in the previous cases undergoing percutaneous hepatic catheterization without such arterial redistribution. In conclusion, these procedures are highly effective to prevent complications of hepatic arterial infusion employing percutaneous hepatic catheterization and to allow continuation of arterial infusion chemotherapy for longer periods.
