摘要
目的 研究溃疡性结肠炎 (UC)治疗前、后肠系膜上动脉 (SMA)、肠系膜下动脉 (IMA)的血流参数和频谱形态的变化。方法 对 16例UC急性期肠系膜上、下动脉的血流参数和频谱形态进行观察 ,其中 9例病变累及左半结肠 ,7例累及全部结肠 ,与治疗后对比 ,并以 10例健康人作对照。结果 病变累及左半结肠、全结肠时IMA的血流参数在治疗前、后有显著差异 (P <0 0 1) ,与对照组对比有显著差异 (P <0 0 1)。SMA在病变累及全结肠时仅RI、PI有显著差异 (P <0 0 1)。结论 肠系膜上、下动脉的多普勒超声 ,可用作评估结肠的感染性疾病 ,估价病变的范围以及治疗的效果。
Objective To study the changes in parameters of blood flow and frequency-spectrum appearance in superior mesenteric artery (SMA)and inferior mesenteric artery(IMA) in the patients with ulcerative colitis(UC). Methods The parameters of blood flow and frequency-spectrum of SMA and IMA in 16 cases of patients with UC were observed before and after treatment, and 10 healthy volunteers served as control. Results The parameters of blood flow of IMA in patients with left half colon UC (9 cases) and all colon UC (7 cases) significantly changed after treatment(P<0.01), and compared with control, there also was a significant difference in these parameters. Only resistance index (RI) and pulsatility index (PI) in the parameters of blood flow of SMA significantly changed (P<0.01) in the patients with whole colon UC. Conclusions Doppler ultrasound of SMA and IMA can be used to evaluate the lesion area and the treatment efficacy in the patients with infectious diseases of colon.
