急性肠系膜上动脉栓塞病程中的甲状腺激素水平

目的：探讨急性肠系膜上动脉栓塞患者血清甲状腺素水平及治疗后的变化规律。方法：选择42例急性肠系膜上动脉栓塞患者，于治疗前和治疗后1、3、7、14、30 d抽取空腹静脉血，利用放射免疫测定方法检测血清FT3、FT4、T3、T4、TSH水平；选择同龄同性别健康查体人员作为对照组。结果：治疗组血清FT3、FT4、T3、T4均明显低于正常对照组，且以肠坏死组最明显（P＜0.05）；治疗后血清甲状腺素降低，30 d后接近正常水平。结论：急性肠系膜上动脉栓塞患者存在低甲状腺素血症，且以肠坏死患者最明显，治疗后随病情逐渐恢复。

Significance of Serum Thyroid Hormone Determination in Patients with Acute Superior Mensenteric Thrombosis

Objective To investigate the alternative regularity of perioperational serum thyroid hormone in patients with acute superior mensenteric thrombosis. Methods Forty-two patients and 42 control ones were selected and their serum thyroid hormone was examined. The serum levels of thyroid hormones （including FT3, FT4, T3, T4 and TSH） were determined by radioimmunoassay perioperationally （ just before embolectomy, the days of the first, third, 7th and 14th post operation） in all the 42 patients. Results Lower levels of thyroid hor-mone were found in the 42 patients with acute superior mensenteric thrombosis, especially in the severe ones;meanwhile lower levels of thyroid hormone of 42 operated patients were deduced further on the first day and the third day post-operation, returned gradually to the primary levels on the 14th day, and the levels returned gradu-ally to normal on the 30th day. Conclusion Patients with acute superior mesenteric thrombosis have lower levels of thyroid hormone especially in severe ones, which are aggravated post-operationally and which will be corrected on the post-operational 14th day.
