Carotid artery exteriorisation in the red deer.

A technique for the surgical relocation of the carotid artery, to permit repeated percutaneous puncture, in red deer, is described. An incision was made through the skin distal to the ramus of the jaw parallel to and dorsal to the superficial jugular vein. The brachiocephalicus muscle was divided by blunt dissection to reveal the carotid artery. The carotid artery was dissected free of connective tissue and the vagus nerve and enclosed in a polythene prosthesis. The brachiocephalicus muscle was sutured dorsal to the now enclosed artery. The wound was closed taking care that the line of sutures did not overlie the prosthesis. Repeated percutaneous puncture of the artery was possible for periods of up to 18 months.
