Abstract		Background. Thorough knowledge about the origin of cystic arteries is surgicaly interesting and important. The analysis of 60 corrosive liver casts showed some interesting origins of cystic arteries not described in the literature. Results. A single cystic artery was present in 85% and double cystic artery in 15%. In majority of cases the single cystic artery originated from right hepatic artery (51,7%) and from right anteriorsectorial artery (20%). In 5% single cystic artery originated from right replacing hepatic artery and in 5% originated from right posterior sectorial artery. We noticed three special cases (5,1 %) where cystic artery originated from subsegment arteries for V, VI and VIII liver segments and two cases where subsegment artery for V and Vl liver segment originated from cystic artery. In 6,7% two cystic arteries originated from right hepatic artery, in 3,3 % both cystic arteries originated from right anterior sectorial artery, in 3,3 % one cystic artery originated from right hepatic artery and another from right anterior sectorial artery. In 1,7% one cystic artery originated from right hepatic artery and another from left hepatic artery. Right hepatic artery crossed anterior to the common hepatic duct in 15% of cases. Conclusions. Results of the study are in accordance with data in literature. Some special cases were found where a cystic artery originated from subsegment live arteries or subsegmental arteries originated from cystic arteries. One must be familiar with the fact that not every artery running over the triangle of Calot is a cystic artery and that often more than one artery supplying the gallbladder can be found. Thorough knowledge about the origin of cystic arteries is surgicaly important when intraoperative or postoperative complications (bleeding) occur.
Summary		Izhodišča. Pri analiziranju korozivnih jeternih preparatov smo opazili nekaj zanimivih izvorov cistične arterije, ki jih v literaturi nismo zasledili. Ker je kirurško zanimivo in pomembno poznati izvor cistične arterije, predstavljamo rezultate študije na 60 korozivnih jetrnih preparatih. Rezultati. Enojna cistična arterija je bila prisotna v 85%, dve cistični arteriji pa v 15%. V večini primerov je enojna cistična arterija izvirala iz desne jetrne arterije (51,7%) in desne anteriorne sektorske arterije (20%). V 5% je izvirala enojna cistična arterija iz desne nadomestne jetrne arterije ter v 5% iz desne posteriorne sektorske arterije. Izstopajo trije primeri (5,1%), kjer cistična arterija izvira iz subsegmentnih vej za V.,VI. oziroma VIII. jetrni segment, ter dva primera, kjer cistična arterija oddaja subsegmentno vejo za V. oziroma VI. jetrni segment. V 6,7% sta bili prisotni dve cistični arteriji, ki sta izvirali iz desne jetrne arterije, v 3,3% sta obe cistični arteriji izvirali iz desne anteriorne sektorske in v 3,3.% je izvirala ena cistična arterija iz desne jetrne arterije, druga pa iz desne anteriorne sektorske arterije. V 1,7% je izvirala cistična arterija iz desne arterije, druga pa iz leve jetrne arterije. Zaključki. Rezultati študije so večinoma primerljivi s podatki iz literature. Izstopa nekaj v literaturi neopisanih primerov, kjer cistična arterija izvira iz subsegmentnih jetrnih arterij oziroma cistična arterija oddaja subsegmentne jetrne arterije. Zavedati se moramo, da ni vsaka arterija, ki jo najdemo v Calotovem trikotniku, cistična arterija in da pogosto več kot ena arterija prehranjuje žolčnik. Izvor cistične arterije postane kirurško pomemben, če pride do zapleta (krvavitve) med operacijo ali po njej.
