Digital subtraction angiography (DSA) is an imaging modality that is widely used not only to diagnose / confirm but also to treat various vascular pathologies. Knowledge of normal anatomy and variations of neck vessels is of utmost importance to perform any neurovascular diagnostic or interventional procedure for obvious reasons. Here we discuss about some variations of vertebral artery incidentally detected during routine DSA at our institute along with its significance and embryological basis.
