El objetivo del estudio fue determinar las variaciones del origen, trayecto y distribución de la arteria suprarrenal superior. Fueron revisadas 83 regiones de fetos humanos de 20 a 40 semanas gestación, perfundidos con vinilo rojo y fijados en formol al 10%. .Después de una cuidadosa observación la encontramos originándose como: 1) Rama de la arteria frénica inferior 79,5%, 2) De la arteria aorta abdominal 6,02%, 3) 2 arterias suprarrenales superiores, una rama de la aorta abdominal y otra de la arteria frénica inferior 2,40%, 4) 2 arterias suprarrenales superiores ramas de la arteria frénica inferior 2,40%, 5) De la arteria suprarrenal común(tronco común entre las arterias suprarrenales superior, media e inferior)originada en la aorta abdominal 1,20%, 6) De la arteria renal 1,20%, 7) Arteria suprarrenal superior rama de la arteria frénica inferior contralateral 1,20%, 8) De la arteria hepática derecha 1,20%, 9) De la arteria suprarrenal media 1,20%, 10) Del tronco celíaco 1,20%, 11) 2 arterias suprarrenales superiores una de arteria suprarrenal media y otra de arteria frénica inferior 1,20%, 12) 2 arterias suprarrenal superior provenientes de 2 arterias frénica inferior desde el tronco celíaco 1,20%.

SUMMARY
The aim of this research was to study the variations on the origin, course and distribution of superior suprarenal artery. 83 regions from human fetuses were studied, all of them with gestational ages between 20 and 40 weeks, injected with red vinyl solution and fixed in a 10% formol solution. After a careful observation, we obtained the following origins: 1) In 79,5% it was a branch from inferior phrenic artery, 2) In 6,02% from abdominal aorta, 3) In 2,40%,
superior suprarenal artery were 2: one from abdominal aorta and one from inferior phrenic
artery, 4) In 2,40%, superior suprarenal artery were 2: both from inferior phrenic artery, 5) In 1,20% from a common suprarenal artery, 6) In 1,20% from renal artery, 7) In 1,20% from contralateral superior suprarenal artery, 8) In 1,20% from right hepatic artery, 9) In 1,20% from medial suprarenal artery, 10) In 1,20% from celiac artery, 11) In 1,20%, superior suprarenal artery were 2: one from medial suprarenal artery and one from inferior phrenic artery, 12) In 1,20%, superior suprarenal artery were 2: both from 2 inferior phrenic arteries.
Key words: Superior suprarenal artery, inferior phrenic artery, variation.
