[Embolization therapy of kidney tumors--experience with a group of 60 patients]

A series of 60 patients is reported, in whom embolization was carried out because of a kidney tumor. In 9 cases, this treatment was given for purely palliative reasons, but in the remaining 51 cases, this treatment was a preoperative measure in order to achieve coagulation or "dry the tumor out" intra vitam. Although we formerly used materials such as gel foam and muscle homogenates, in the last three years, Ethibloc or pure alcohol has been used exclusively. The risks involved in this therapy are discussed. In patients with large arteriovenous shunts or fistulas, alcohol should not be used and we prefer polyacrylic agents like Ethibloc.
