Comparison of short-term effects between interventional embolization treatment and iodine-131 therapy for Graves' hyperthyroidism / 介入放射学杂志

ABSTRACT

Objective To compare the short-term effects between interventional arterial embolization and iodine-131 therapy in treating Graves'disease.Methods A total of 84 patients with Graves'disease (GD),confirmed by clinical data and laboratory tests,were divided into two groups:interventional group(n=42)receiving arterial embolization and iodine-131 group(n=42)receiving iodine-131 therapy.Before and after the treatment thyroid angiography and SPECT/CT imaging were performed to determine the shape and size of the thyroid,and radioimmunoassay method was used to measure serum levels of FT3,VF4,TSH and TRAb at 3.6 and 12 months after the therapy.The results were compared and statistically analyzed.The occurrence of complications was observed. Results No statistically significant difference in short-term therapeutic effects was found between interventional group and iodine-131 group.The occurrence of early severe complication was much higher in interventional group than that in iodine-131 group,while the occurrence of hypothyroidism was obviously higher in iodine-131 group than that in interventionai group.Conclusion Both interventional embolization and iodine-131 therapy have reliable effect for the treatment of Graves'disease.Iodine-131 therapy may be used in patients who plan to receive initial treatment or in patients who failed to effectively respond to other kinds of therapies,while interventional embolization may be employed in patients who are not able to receive surgery or in patients who have failed to respond to antithyroid drug treatment,or in patients whose iodine-131 intake rate is too low to undergo iodine-131 therapy,especially in patients with refractory and intractable hyperthyroidism. Interventional embolization can be regarded as an alternative treatment for Graves'disease.
