Abstract
BACKGROUND AND PURPOSE:
Fetal origin of the posterior cerebral artery is a common anatomic variation in the posterior cerebral circulation. It is estimated to occur in up to 30% individuals. The aim of this study is to show the incidence of unilateral and bilateral fetal origin of he posterior cerebral artery of the population in R. Macedonia.
MATERIALS AND METHODS:
The sensitivity and specificity of multidetector CT angiography are reported to be high (819-90% and 93%, respectively). Retrospectively we reviewed random multidctector CT Angiography studies of 100 patients in our clinic, to determine the incidence of fetal origin of the PCA of the population in R. Macedonia ( sex and age was not taken into account)
RESULTS:
Form the randomly selected 100 individuals examined in our clinic in the last year, 32 (32%) had fetal PCA, and only 4(49) of those had bilateral fetal PCA. From the 28 individuals with unilateral fetal origin of the posterior cerebral artery, 19 had right fetal PCA and 9 had left
fetal PCA.
CONCLUSION:
The study showed that the incidence of fetal origin of posterior cerebral artery of the examined population in R. Macedonia Is 32%. The incidence of unilateral fetal PCA Is 29% and of bilateral fetal PCA IS 4%. From all the examinees 19% have unllateral right and 9% unilateral left fetal PCA.
