摘要
为了探讨血管造影(DSA)在胃癌诊断中的应用价值,作者对36例胃癌患者术前DSA与术后病理进行了观察研究。结果显示:其中2/3以上的胃癌能显影,变换体位可观察肿瘤立体图像,参照周围组织结构,可判断肿瘤毗邻关系;血管被浸润可呈多种征象,一处狭窄或闭塞,提示肿瘤呈局限性倾向,恶性程度偏低;多处狭窄或闭塞,呈锯齿状或串珠状,则提示肿瘤浸润性较强,恶性程度高。作者提出胃癌浸润深度的DSA诊断标准:(1)血管粘膜下吻合枝出现狭窄或闭塞者为早期癌;(2)血管壁枝动脉出现狭窄或闭塞等为浸润肌层;(3)胃周围血管弓出现狭窄等为浸润浆膜;(4)主要动脉根部及其它脏器血管出现变化则为直接浸润周围脏器。作者认为,DSA为胃癌诊断提供了新的方法,与其它方法相结合会使术前确诊率更为提高,具有较高的应用价值。
To improve preoperative diagnosis of gastric cancer,we applied DSA in clinical diagnosis.36 patients with gastric cancer were observed.Preoperative DSA and postoperative pathological analysis revealed the following results.With DSA,the accuracy of diagnosis of invasion depth of gastric cancer reached 72 2%.We summarised the criteria for diagnosis of gastric cancer.If subsidiary anastomotic channels narrow or obliterate in DSA,the case may be early cancer.If parietal branches narrow or obliterate in DSA, the cancer may invade the muscle of the stomach.If arcade of this lesser curvature narrows in DSA, the cancer may invade the serosa of the stomach.If the roots of main vascular vessels,such as the left gastric artery,and vascular vessels of other organs narrow or obliterate in DSA,the cancer may directly invade other organs as well.Two thirds of gastric cancer could be identified through DSA with their shapes and characteristics.The varied shapes of vascular vessels caused by invasion of gastric cancer could reveal growing mode of the cancer.
