摘要
目的：探讨二维及彩色多普勒超声对亚急性甲状腺炎诊断及随访观察的临床意义。方法：对47例经病理、实验室检查及典型临床表现确诊的亚急性甲状腺炎患者进行二维及彩色多普勒超声检查，同时对所有患者治疗后进行超声随访观察。结果：所有亚急性甲状腺炎患者甲状腺内均出现局限性或弥漫性不均匀低回声区，边缘不规则，边界欠清，并伴有压痛，病变部位内血流信号较丰富，其内的动脉血流表现为低速低阻的特点，弥漫型及局限型中病变范围较大者（病变范围大于同侧甲状腺叶的50％）患侧甲状腺上动脉血流速度明显增快（P＜0.01）；局限型中病变范围较小者（病变范围小于同侧甲状腺叶的50％）患侧甲状腺上动脉血流速度无明显增快（P＞0.05）。治疗后，40例患者在声像图恢复正常后停药，无复发；7例在临床症状、体征好转而声像图仍可见亚急性甲状腺炎表现时自行停止治疗后均复发。结论：二维及彩色多普勒超声对亚急性甲状腺炎的诊断有重要价值，治疗过程中超声随访观察对指导治疗有重要临床意义。
Abstract
Objective: To investigate the value of two-dimensional and color Doppler ultrasonography in the diagnosis and follow-up of subacute thyroiditis(SAT). Methods: Forty-seven patients were diagnosed as subacute thyroiditis by pathology, laboratory examination and clinical symptoms, then all the patients were checked with two-dimensional ultｒａsonography and color Doppler imaging. At the same time, they were also follow-up after related treatment. Results: Local or diffuse low echo area of thyroid gland appeared in all the subacute thyroiditis patients, with no regular and clear edge, and accompanying with pain at palpation. The blood stream signal in pathological region(diseased region) was abundant, with low blood flow inside the artery, The blood flow of the patients with local and diffuse echo area was obviously quick(P<0.01), when the pathological area was larger than 50% of the same side of the thyroid gland. However, when the pathological changes of local low echo area was smaller than 50% of the same side of the thyroid gland, the blood flow ｄｉｄ not increase significantly compared to the normal thyroid gland(P>0.05). After being given related treatment, the ultrasonographic image of 40 patients returned to normal level and did not recur after withdrawal of treatment. The clinical symptom and objective sign in 7 patients became better, the illness recurred after withdrawal of treatment when symptom of subacute thyroiditis was disappeared from the ultrasonographic image. Conclusions: Two-dimensional and color Doppler ultrasonography has played an important role in the diagnosｉs of subacute thyroiditis, meanwhile, it also showed a very key clinical value during the treatment process.
