Abstract:
Objective To investigate the hemodynamic characteristics of superior thyroid artery and its corresponding clinical significance with patients of Graves'hyperthyroidism.Methods Thirty patients with Graves'hyperthyroidism received Doppler ultrasonography.Patients were grouped with different serologic indices at 4 month after radioiodine therapy as relief(R),uncured(U)and hypothyroidism(H).The relationships between thyroid volume(V),superior thyroid artery peak systolic velocity(PSV),end diastolic velocity(EDV),RI,PI and systolic accelerating time(SAT)and the 4-month outcome were analyzed respectively.Results Besides the effect of 24 h-131I uptake rate on patients'short-term outcome,V,PSV and RI were of predominate prognosis value(P＜0.01).PSV and V of group R were positively correlated with 131I dose respectively(r1=0.825,r2=0.697;P＜0.001),while SAT of group R was negatively correlated with 131I dose(r=-0.489,P＜0.05).Conclusions Patients with high V,PSV and RI maybe still suffering hyperthyroidism after regular dosage of 131I therapy.Doses of 131I should be added appropriately for patients with high PSV and V,but short SAT to achieve complete remission,while it should be reduced for patients in opposite condition to avoid occurrence of hypothyroidism.
