[123I-MIBG myocardial SPECT in two patients with familial amyloid polyneuropathy].
201T1C1 SPECT and 123I-MIBG SPECT were performed in two patients with familial amyloid polyneuropathy (FAP). Both patients showed normal accumulation of 201T1C1 and no accumulation of 123I-MIBG in the myocardium at the early and delayed images. These results indicate that the patient with FAP-related myocardial change accompanies sympathetic nerve dysfunction. The dysfunction is supposed to be caused by disturbance of re-uptake of MIBG by the terminal ending of the sympathetic nerve (uptake-1) through the amyloid-deposited connective tissue.
