[Anatomic variants of hepatic artery in metastatic affection of the liver]

On 39 nonfixed cadavers of patients, in whom hepatic metastatic affection was diagnosed in abdominal cavity tumors, there were studied up a hepatic artery anatomic variants and possible accesses. In 22 observations there was noted a typical variant of hepatic artery branching from a. hepatis communis, in 9--isolated blood supply of the left and right hepatic lobes, in 4--additional branches of various diameter from a. gastrica sinistra to the left hepatic lobe, in 2-- additional branches toward the right hepatic lobe, branching from a. mesenterica superior, in 1--the blood supply of the left hepatic lobe by arterial branch from splenic artery, while a lienalis-hepatic trunk have branched from truncus coeliacus. In one observation there was revealed the common hepatic artery branching on three trunks, while the median one have supplied a hepatic quadrate lobe. It is expedient in all observations perform en bloc lymph node dissection of hepatic hilus with the truncus coeliacus structures opening. The proposed order of activities while conduction of selective intraarterial polychemotherapy permits to take into account the anatomic variants as well and to eliminate the possible faults and complications occurrence.
