| 目的：建立小肠疾病的血管形态, 为介入、螺旋CT(HCT)诊断和介入治疗提供依据。材料与方法：对8例正常新鲜小肠标本, 10例平滑肌肿瘤(15个瘤体), 6例腺癌, 3例类癌及6例Crohn病均经病理证实的手术切除小肠标本, 采用血管造影、量化分析(CMIAS007)及病理观察。结果：正常小肠动脉分布具有一定规律性, 空肠段直动脉通常分为三支(两长支, 一短支), 回肠段直动脉通常分为两支(长、短各一).小肠平滑肌肿瘤血管特征：供血动脉增粗, 沿瘤蒂进入瘤中心, 放射分布、丛状增生、彼此吻合形似“蜘蛛网”状(spidernetwork), 血管扭曲、中断、瘤中心造影剂池征(contrastmediumpuddle)提示平滑肌肉瘤。小肠腺癌以癌周血管增多、增粗、扭曲, 癌实质血管减少为特征。小肠类癌的供血动脉受压移位、中断, 癌实质血管少。小肠Crohn病以血管增多, 增粗, 吻合丰富, 但仍保持正常血管的分配规律, 还可见到血管纡曲、空穴现象及淋巴结肿大、染色征。结论：小肠平滑肌肿瘤为多血管肿瘤, 良、恶性之间存在一定特点。小肠腺癌癌周血管丰富, 癌实质血管少。小肠类癌为少血供肿瘤。小肠Crohn病为血管增多疾病, 但仍保持正常分配规律。 |

| Purpose:To establish vascular morphology of the diseases of small intestine for interventional and HCT diagnosis and therapy.Materials and Methods:8 cases of small intestinal autopsy specimen of normal adults,25 cases of abnormal small intestine specimem (which pathologically comfirmed of 10 cases of leiomyomatous neoplasms,6 cases of carcinomas,3 cases of carcinoids,6 cases of crohn diseases) were studied by angiography,quantitative analysis with CMIAS 007 system and pathological diagnosis.Results:Vasa recta in jejunum frequently divided into three branches two long and one short branches,in the ileum,it often divied into two branches one long and one short branches.In the leiomyomatous neoplasms,it was commonly observed that the supply arteries dilated clumply proliferated and anastomosed.looked like “spider network”.Largetortuous,breaking off,contrast medium puddle were obviously observed in the leiomyosarcoma.In the carcinoma,the feeding arteries manifested that dilated,broke off proliferated surrounding the mass.While in the parenchyma of carcinoma was poor in vascularity.The blood vessels of carcinoid shifted closed and tortuous,but it dosen’t dilate and proliferate.In crohn disease,There were some features of proliferated,dilated of vasarecta,which has normal distribution rules.Conclusion:The leiomyomatous neoplasms are rich in vascularity.the benign and malignant trmor possess different vascular feature.There are rich vascularized in edge of carcinoma and poor vascularized in certre of carcinoma,The carcinoids are poor in vascularity.Crohn’s diseases have rich blood vessels which there are distribution characteristics of normal vasa recta.The study is help for interventional and HCT diagnosis and therapy. |
