The clinical application of interventional treatment before operation in nodular goiter (giga-type)

Objective: To evaluate the therapeutic effect and safety of nodular goiter (giga-type) operation after in- tervention therapy. Methods: 5F-type catheter or sp micro-catheter was catheterized selectively into upper thyroid artery using Seldinger technique through femoral artery. The thyroid artery was embotized with gelatin sponge particles after ipsilateral thyroid arteriography, tand thyreoidectomy was performed 1 week later. Results: After the interventi on therapy, the size of the tumor deflated over 40% in 4 cases, and over 30% in 3 cases. The thickening blood vessels became thin and flat or obstruction, and thyroid tissue cross-section became pale and tenacious. There was little bleeding during the operation. No patient appeared the damage of laryngeal nerve or parathyroid body, the secondary hypothyroidism or thyroid crisis during six months to one year follow-up. Conclusion: It is a safe, effect method with few complications and high cure rate to operating after thyroid artery embolization, and is worth to be practiced further in clinic. (authors)
