Gluteal artery occlusion: intra-arterial chemotherapy of pelvic neoplasms
D Woods, W Bechtel, C Charnsangavej, TP Haynie, EE Kim, CH Carrasco and S Wallace
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.
