Variation of the Lateral Sacral Artery in relation to Sciatic Neuropathy

Table 2

The incidence of the lateral sacral arteries number observed in series studies and current study.

Single	0%	30%	55%	26%	50%	77.2%

The lateral sacral artery commonly arose from the internal iliac artery in different numbers but was found to be absent in one specimen. Observations are based on 342 specimens.
