A 3-year-old female suspected of laryngomalacia had nasotracheal intubation for 23 days after birth. Tracheotomy was performed because of asphyxia on removal of the nasotracheal tube.

Superior thyroid artery was catheterized using Fogarty E-040-4F catheter. The balloon was removed and a small notch was left at the tip. The catheter was inserted in the superior thyroid artery up to the small notch and the catheter was fixed tight by two ligatures , the notch being

A case of the hypopharynx andd cervical esophagus successfully treated by arterial infusion method combined with radiotherapy was reported.A 51-year-old male with chief complaint of dysphagia was diagnosed as having a tumor arising from the left side of the esophageal wall at the level of the first narrowing, extending toward the opposite side. Histological diagnosis of squamous cell carcinoma with keratinization was made by biopsy. Teflon catheters were inserted into; (1) the right superior thyroid artery for infusion via the superior laryngeal artery, (2) bilateral superficial cervical arteries for infusion via the inferior thyroid arteries, and (3) the left superior thyroid artery for infusion via its posterior ramus, with some time intervals. Infusion of 5-FU was carried out with simultaneous 65Co irradiation and the total amount of 8,000mg of 5-FU, i.e., 2,000mg for each of the four arteries, was given with the total irradiation dose of 5,000rad. After these treatments, the symptom of dysphagia subsided and the tumor disappeared on fluoroscopy. The so-called

We have tried to apply anti-cancer drugs by the method of arterial injection to inferior thyroid artery for the treatment of the laryngeal cancer. The patient was a 66-year-old Japanese male with the cancer mainly located in the posterior commissure of the larynx. After truncus thyreocervicalis and its branches were exposed, the Hakko's teflon tube with the outside diameter 1mm was retro-catheterized through transversa colli artery. We are always mindful of that an anatomical variety exists on truncus thyreocervicalis and inferior thyroid artery. Using dyestaining method we confirmed that the end of the catheter was definitely in truncus thyreocervicalis and not in subclavian artery. Thereafter, the catheter was fixed. It was then lead to the outside of the skin on the shoulder. Other arteries except ascending colli artery, which supplies partially the spiral cord, were ligated in expectation of effective arterial injection through inferior thyroid artery. Two modes of the treatment consisting of 5-FU arterial injection and irradiation were combined. The total dosage of the anti-cancer drug was 3,125mg and irradiation dose was 2,200 rads. The tumor in the posterior commissure disappeared, but it remained in the farther anterior part of the commissure. This suggests that inferior thyroid artery might supply blood only to the region of posterior crico-arytenoid muscle, namely the region of the posterior commissure. Therefore, we directly injected 5-F5 into the cricothyroid branch artery using Thermo 27 G needle under microscope and simultaneously employed the radiotherapy.
