Selective embolization of the vesical artery in the management of massive bladder hemorrhage.

Massive bladder hemorrhage was sucessfully treated by selective embolization of the unilateral vesical artery in two patients with vesical neoplasms. In one patient, complete hemostasis was obtained by partial occlusion of the unilateral vesical artery, although the lesion had another feeding vessel from the contralateral artery. This method is simple and effective in controlling massive bladder hemorrhage, as it has the advantages of minimizing ischemic pain, preventing the hazards due to extensive infarction and reflux of embolic material, and reducing tumor bulk.
