Abstract
The Internal carotid artery (ICA) is one of the branches arising from the Common carotid artery. A study of variability in the origin and course of the cervical part of the ICA is clinically important for vascular surgeons in performing certain stenting procedures.The present study was conducted to study the variations in the origin and course of the cervical part of the ICA by cadaveric dissection method. A cadaveric study was conducted on fifty, formalin fixed head and neck specimens in the department of Anatomy, Pushpagiri Institute of medical sciences and research centre, Tiruvalla, Kerala, India. The pattern of origin, course of the cervical part of ICA were dissected and variations, if any, were noted.Internal carotid artery originated from the Common carotid artery in 100% of the specimens. High origin of the ICA (38%) was the commonest variation in the origin observed with a higher incidence on the right side. The commonest variations in the cervical part were kinks (32%) with a higher frequency on the left side and aneurysms (4%) with equal distribution on both sides.Anomalous origin and course of ICA may damage the vessel while performing certain surgical procedures like stenting. Thus sound knowledge of the variations in the origin and course of the vessel is essential for general and vascular surgeons in performing surgical procedures without unnecessary complications.
