Extrahepatic regional chemotherapy: use of technetium-99m labeled macroaggregated albumin.
The purpose of this study was to verify the applicability of nuclear techniques with technetium-99m labeled macroaggregated albumin (Tc-99m-MAA) in extrahepatic regional chemotherapy. Of 98 patients in whom arterial Port-a-caths were implanted by transcutaneous access, 13 were treated by regional extrahepatic chemotherapy (breast, one; pancreas, four; kidney, one; uterus, three; vagina, two; bladder, two). In all 13 patients, Tc-99m-MAA was slowly infused intraarterially. The examination showed the perfusion of the area with the neoplasm and excluded the presence of important misperfusions of Tc-99m-MAA to the nearest areas. To detect the presence of an arteriovenous shunt with systemic misperfusion, an anterior image of the thorax was obtained in all patients and an index of misperfusion was calculated. In 12 patients, the index was < 5%; in one patient it was about 40%. In conclusion, our preliminary experience concerns the monitoring of intraarterial infusion chemotherapy of extrahepatic districts. In all 13 patients, we evaluated the correct positioning of the intraarterial catheter and the distribution pattern of the arterial flow, with a semiquantitative indication of arteriovenous shunting. This method gave us an instrument of study that was inexpensive, harmless, and free of collateral complications.
