Embolotherapy with detachable silicone balloons: technique and clinical results

Catheter techniques and early clinical results of therapeutic embolization with detachable silicone rubber balloons are described in 13 patients. Effective control of post-traumatic or spontaneously occurring hemorrhage or preoperative devascularization of neoplasms was achieved in 10 patients. Three additional patients, one each with pelvic arteriovenous malformation. pulmonary arteriovenous malformation, and hemangioendothelioma of the liver, were partially treated by balloon occulsion. Therapeutic embolization with detachable silicone balloons provides a method of long-term, extremely selective arterial occlusion with reduced risks from inadvertent embolization of neighboring circulations.
