title: Gluteal artery occlusion: intra-arterial chemotherapy of pelvic neoplasms.
abstract: Intra-arterial chemotherapy of pelvic tumors may be complicated by coincident flow to the buttocks. Transcatheter occlusion of both the superior and inferior gluteal arteries may have a role in directing the flow of chemotherapeutic agents away from the buttocks and toward the true pelvis. The results of flow studies using technetium-99m-labeled macroaggregated human serum albumin were compared in 12 consecutive patients examined before and after transcatheter arterial occlusion, and the best results were obtained by selective occlusion of those arteries that demonstrated increased flow to the buttock on the initial study. Without the preselection of patients in whom the initial flow went mainly to the buttock, the results were inconsistent. Because of the increase in the procedure time and the occurrence of minor complications, such as local pain during or after the occlusion procedure, in all patients, proper patient selection is important.
