B. Tillmann et C. Christofides, THE CLINICALLY UNSAFE TORTUOSITY OF THE I NTERNAL CAROTID-ARTERY - ANANATOMICAL STUDY, HNO. Hals-, Nasen-, Ohrenarzte, 43(10), 1995, pp. 601-604
Variations of the clinical course of the internal carotid artery in th
e parapharyngeal space were studied in order to define possible causes
of acute hemorrhage during pharnygeal surgery. Four cases of sigmoid
tortuosity involving the internal carotid artery were found in a total
of 81 dissected carotid sheathes and 8 corrosion casts. In 2 cases th
e internal carotid artery was located in direct contact with the tonsi
llar fossa to form a clinically unsafe carotid tortuosity that was con
sidered at risk during tonsil surgery.
