Intractable, chronic vaginal and/or vesicle bleeding complicating pelvic cancers in 5 women was treated by transcatheter embolization of the hypogastric artery or its branches. Bleeding was presumed to be from hypervascular granulation tissue formed in response to irradiation in 2 patients and tumor tissue in 3. The embolic materials were Gelfoam and Oxycel reinforced autologous clots. Bleeding was stopped or reduced in volume by at least 90% in each patient. This form of therapy was useful even though the bleeding site was not demonstrated angiographically.
