A Case Report of Face Aneurysm of Right Common Carotid Artery Take off and Co-Morbid Right Recurrent Laryngeal Nerve Injury

Central vein catheterization for providing an efficient access for haemodialysis, is a known procedure with many complications. In order to constructing a good circulatory access, temporary or long lasting one, we would be able to use trans jugular, subclavian or femoral vein roots. Inserting the catheter through these ways to access the central circulation necessitates passing through the vital anatomical elements as arteries, nerves, lymphatics and relative vessels that contain possibility of predisposing to complications such as bleeding, hematoma, arterio-venous fstula, Pseudoaneurysms, nerve bandle injury, hemo-pneumothorax, cardio-conductive disability or air embolism. Most of these complications are directly related to the capability of introducers. Today, cannulation with the guide of radiologic facilities or ultrasonography could be able to eliminate the complications. Progressive hematoma due to arterial puncture and bleeding are the most common early complications and so common carotid artery and its branches, subclavian artery and neighboring branches are the most involved elements. Pseudoaneurysms, arterio-venous fistulas and also nerve injuries are rarely reported as late complications. The most dangerous is Pseudoaneurysms that potentially endangers the patient because of compressing effect on vital organs. This paper reports a rare primary nerve injury which was accompanied by a rare positoinal pseudoaneurysm in the proximal base of common carotid artery produced by indwelling central vein catheter for hemodialysis via right internal jugular vein.
