STUDY OF VARIATIONS IN THE HEUBNER’S ARTERY

Dr. A. Thenmozhi and *Dr. C. Subadha

ABSTRACT

Background: Intracranial aneurysm is most common in anterior circulation of circle of willis. Recurrent Artery of heubner (RAH) is the first artey seen on elevating the frontal lobe to approach the aneurysm present in anterior communicating artery. In this study Recurrent Artery of heubner presence, numbers and site of origins were noted Materials and Methods: The recurrent artery of Heubner were studied in 50 formalin fixed human brains (100 hemispheres) obtained from routine autopsies with 10x magnification. Results: The RAH was found in 98% of hemispheres and it was missing in 2% hemispheres Among the 98% 0f hemispheres, it is doubled in 10 hemispheres, out of 10 double RAH, the 6 arteries with a separate origin and 4 arteries from a common stem. The RAH originated from at the level of ACoA of the Anterior cerebral artery (ACA) in 57% of specimens, from A2 segment in 34% and from A1 segment in 7%. Conclusion: The knowledge of anatomical variations in heubner’s artery is essential for neurosurgeons to planning the neurosurgical procedures to avoid unexpected neurological complications.
