Usually the posterior cerebral artery (PCA) arises from the basilar artery, when the PCA originates from the internal carotid artery (ICA); such a condition is designated as fetal variant of the PCA (fPCA). It is further classified into complete fetal PCA (cfPCA) when the posterior cerebral artery originates completely from the ICA. The present study was done to assess the prevalence of completef PCA in western UttarPradesh population and compare the results with available data in literature.
GE OPTIMA MR 360(1.5 T) was used for obtaining the magnetic resonance angiographs (MRA). MRA of 92 subjectswere reviewed out of which 70 were males and 22 females, aged between 20–75 years
Complete fPCA was found in 6.5%. This variation was observed on the right side in 2.1% subjects and on left side in 4.2%. The males showed a predilection for this variation (4.2%) as compared to females (2.1%).
This variation is common on the left side and more common in males.
