Abstract
Collateral vessels in tumors and arteriovenous malformations limit the effectiveness of therapeutic embolization. Capillary propagation of embolization media represents a possible solution of the problem. Embolization with Ethibloc (Hamburg-Norderstedt), a vegetable protein dissolved in alcohol, was performed in 15 renal arteries of dogs. Three embolized kidneys were completely resorbed, and four kidneys showed complete necrosis microscopically. Ethibloc in combination with 40% glucose guarantees homogenous embolization of the entire arterial bed including the capillaries. No complications were observed in other organs.
