ABSTRACT

Central venous catheters are usually safe and placed with minor procedure easily but may sometimes be associated with some major and minor complications. One of the complications is hematoma. The frequency of the hematoma formation can be changed due to the method of insertion by specialist, medical status of the case and the problems that require intervention. The cervical vagus nerve runs parallel to the carotid artery on its lateral side. A cervical cardiac branch is given off along the course of the cervical vagus or in some cases from the superior laryngeal nerve. This nerve branch is also termed aortic branch or depressor nerve and contains mainly afferent fibers from baroreceptors of the aortic arch. Vasovagal reactions during the arteriovenous interventions or compression on the vagal site may be much more frequent. Hematoma related vasovagal bradycardia due to jugulary catheter complication may be kept in mind.
