Superior Vesical Artery
Abstract
The number of superior vesical arteries varies from one to five. They commonly arise from the umbilical artery, but were also found arising from the uterine (6 of 66 sides), the vesicodeferential (6 of 66 sides), and the obturator (6 of 132 sides). A large anastomosis between the superior and inferior vesical arteries was found in 60 of 70 specimens. Parsons and Keith reported on 58 observations of the superior vesical artery as part of the program of the Committee of Collective Investigation of the Anatomical Society of Great Britain and Ireland.

Parsons and Keith reported on 58 observations of the superior vesical artery as part of the program of the Committee of Collective Investigation of the Anatomical Society of Great Britain and Ireland. In 44 cases (75.9%) it arose from the hypogastric trunk (internal iliac); in 2 of these cases the artery was doubled; in 9 cases (15.5%) it came from the anterior division, in 1 of these the artery was doubled; in 4 cases (7%) it came from the internal iliac; and in 1 case, in common with the middle hæmorrahoidal (middle rectal), from the hypogastric trunk (internal iliac).
Variations in the Number (%) of Superior Vesical Arteries
Levi Dubreuil-Chambardel
Number of Arteries % %
One Superior Vesical Artery 10 9
Two Superior Vesical Arteries 70 74
Three Superior Vesical Arteries 12 9
Four Superior Vesical Arteries 8 6
Five Superior Vesical Arteries 8 2
Older anatomists, such as Tiedemann, Portal, and Henle describe a single superior vesical artery, but Soemmerring indicates to the contrary, two to five vessel (duas ad quinque arterias vesicales). The research of Levi and Dubreuil-Chambardel confirm each other that the number of branches varies from one to five. from Dubreuil-Chambardel, 1925.
