目的:分析小肠平滑肌肿瘤的血管造影的X线表现,探讨血管造影对小肠平滑肌肿瘤的临床应用价值。材料和方法:应用选择性肠系膜上动脉造影,回顾性分析了11例小肠平滑肌肿瘤的血管造影征象。结果:血管造影主要表现为:①肿瘤的供血动脉增粗;②动脉期显示一团病理血管;③可有血管池;④肿瘤染色;⑤可出现静脉早显。结论:①血管造影对小肠平滑肌肿瘤的诊断价值优于钡剂造影和内镜检查,可作为本病的首选方法。②定位诊断必需仔细寻找病变的供血动脉发出的解剖位置作出诊断。③对良、恶性平滑肌肿瘤鉴别诊断提出了有参考价值的X线征象。
Objective: To analyze the X-ray findings of angiography of small intestine smooth muscle tumors, and to explore the clinical application value of angiography in small intestine smooth muscle tumors. Materials and Methods: Selective superior mesenteric artery angiography was used to retrospectively analyze the angiographic signs of 11 small intestinal smooth muscle tumors. RESULTS: The main manifestations of angiography were: 1 thickening of blood supply arteries; 2 arterial phase showed a group of pathological blood vessels; 3 may have vascular pool; 4 tumor staining; Conclusion: 1 The diagnostic value of angiography in small intestine smooth muscle tumors is better than that of barium contrast agents and endoscopy. It can be used as the first choice for this disease. 2 Positioning diagnosis It is necessary to carefully search for the anatomical position of the feeding artery of the lesion to make a diagnosis. 3 The X-ray signs are valuable for the differential diagnosis of benign and malignant smooth muscle tumors.
