Variation of Origin of Left Vertebral Artery: Phylogenic Correlation and Clinical Implication
Journal Title: International Journal of Medical and Health Sciences - Year 2013, Vol 2, Issue 4
Abstract
Variations in the branching pattern of aortic arch are caused by alterations in embryological mechanisms and are implicated in certain clinical manifestations. Anomalous origin of supra aortic arch vessels are common and their detection is important for vascular surgeries of thorax and head and neck. Stenosis of Vertebral Artery (VA) is an important etiological factor for stroke involving posterior cerebrum. Advanced imaging studies like angiograms reveal conditions like VA occlusion prior to surgery. During the course of routine cadaveric dissection for student demonstration a 62 year old male cadaver presented unusual origin of Left Vertebral Artery (LVA). Anomalous of origin and distribution of LVA and its branches can lead to impaired cerebral hemodynamics and cerebral dysfunctions.
