Title: A Study on Cervical Symphatetic Chain and Raynauds Phenomenon.
Abstract: The cervical part of the sympathetic trunk contains three interconnected ganglia -superior, middle and cervicothoracic.They send grey rami communicantes to all the cervical spinal nerves.The study was conducted on 157 cadavers (99 Male & 58 Female) bilaterally.Superior cervical ganglion was observed in all the cases.Middle cervical ganglion was found in 58.5% of the cases which lies between the common carotid artery in front and loop of inferior thyroid artery behind.Ansasubclavia extends from middle cervical ganglion to inferior cervical ganglion in 12.5% of the cases.Inferior cervical ganglion was observed in the 45% of the cases.The stellate ganglion was observed in 55% of the cases.The variations of the cervical sympathetic trunk were noted and photographed.Stimulated by the need of surgery, anatomy of the cervical sympathetic chain has acquired increasing importance.To diminish the potential risk of injury during surgery better surgical methods are to be developed.
