Ispitivanje protoka krvi kroz hemangiom jetre radionuklidnom angiografijom
Institut za nuklearnu medicinu KCS, Beograd

Sažetak

U 12 bolesnika sa hemangiomom jetre urađeno je dinamsko ispitivanje prvog prolaza intravenskog bolusa 99mTc-pertehnetata kroz jetru. U 8/12 bolesnika hemangiom se na angioscintigramima prikazao kao zona sa manjim protokom krvi (hipoaktivna), a u 4/12 nije se uočavala razlika u odnosu na tkivo jetre. Vremena dospevanja radiofarmaka i trajanja arterijske i venske faze njegovog prolaza kroz tkivo jetre i hemangiom ne razlikuju se značajno. Vrednost koeficijenta pravca (nagiba) krive radioaktivnosti hemangioma, koja je proporcionalna protoku krvi, u venskoj (portnoj) fazi prvog prolaza visoko signifikantno je manja nego jetre (p<0,01). Ovo kao i značajno niža srednja vrednost perfuzionog indeksa hemangioma (PIH=0,34) u odnosu na hepatički perfuzioni indeks (HPI=0,57) ukazuje na to da je protok krvi kroz hemangiom dominantno ili isključivo arterijski (p<0.05). Dobijeni rezultati pokazuju da regionalno određivanje perfuzionog indeksa i drugih parametara hepatičke radionuklidne angiografije omogućuje razlikovanje tkiva sa različitim intenzitetom i obrascem protoka krvi.
