Surgical method for catheter placement via the occipital artery by an approach from the posterior of the mastoid process

Abstract

Catheter placement for continuous intra-arterial chemotherapy in head and neck cancer is generally performed via the superficial temporal artery. If placement via this artery is impossible, other arteries, such as the occipital artery, are chosen. A surgical method has been developed for catheter placement in the occipital artery by approaching from the posterior of the mastoid process. Catheter placement was performed by this method in 15 patients with oral squamous cell carcinoma. Target arteries were the lingual artery in seven cases, facial artery in three cases, maxillary artery in three cases, superior thyroid artery in one case, and the occipital artery itself in one case. The occipital artery was exposed without fail and catheter placement was completed in all patients. The wound healed without complication after treatment. This approach via the occipital artery is a useful technique to achieve continuous intra-arterial chemotherapy in head and neck cancer, especially for cases in which catheter placement is impossible via the superficial temporal artery.
