| 目的 探讨缺血性结肠炎的超声图像特点以及超声诊断价值。方法 使用3. 5～5. 0 MHz 腹部探头和7. 0～14. 0 MHz 高频超声对12 例因急性腹痛、便血患者行二维基波、自然组织谐波和彩色多普勒超声检查,分析结肠肠壁增厚的部位、范围、壁厚和彩色多普勒血流等声像图特征。结果 全部病例经结肠镜或临床治疗监测、随访证实,超声定位符合率100 %(12/ 12) ,其中病变累及右半结肠1 例(8. 4 %) ,左半结肠7 例(58. 4 %) ,横结肠2 例(16. 6 %) ,脾曲2 例(16. 6 %) 。增厚结肠壁的长度范围10. 0～20. 0 cm(平均15. 0 cm) ,壁厚0. 5～2. 0 cm(平均1. 3 cm) ,病变呈均匀、全周性增厚。CDFI :全部病例肠系膜上动静脉内未见血栓,4 例(33. 3 %) 增厚结肠壁间有少量彩色血流信号,8 例(66. 7 %) 未见彩色血流信号。结论 超声对病变的分布、范围、肠壁厚度、彩色血流等做出正确的判断,超声对缺血性结肠炎的诊断和随访、监测对临床有重要帮助。 |

| Objective To investigate the characteristics and value of ultrasound in the diagnosis of ischemic colitis. MethodsFundamental imaging , native tissue harmonic imaging and color Doppler imaging were performed in 12 patient s with acuteabdominal pain and rectal bleeding. The probe f requencies were 3. 5 - 5. 0 MHz and 7. 0 - 12. 0 MHz. We analyzed the loca-tion , approximate length , colon wall thickness and color Doppler flow imaging of the involved colonic segment . Results Allthe diagnosis were confirmed by colonoscopy or t reament montoring and follow-up. The location of the ischemic colitis couldbe shown correctly in 12 of 12 patients (100 %) . Ischemic colitis was identified on the right side in one patient (8. 4 %) , inthe lef t side in seven patient s (58. 4 %) , in the t ransverse colon in two patients (16. 6 %) , in the splenic flexure in two pa-tient s (16. 6 %) . The length of involvement varied f rom 10. 0 - 20. 0 cm (mean length , 15. 0 cm) . The symmet ric thicknessof the colon wall ranged f rom 0. 5 to 2. 0 cm (mean , 1. 3 cm) . Little color Doppler flow was observed in the wall of the af-fected colon segment in four patient s (33. 3 %) . Flow was absent in the eight patient s (66. 7 %) . There was no thrombusdemonst rated in the superior mesenteric vein or superior mesenteric artery. Conclusion Ult rasound could correctly estimatelocation , approximate length , wall thickness and color Doppler flow imaging of the involved colon. Ult rasound plays an im-portant role in diagnosis , follow-up and monitor of ischemic colon disease. |
