肝脏疾病的血管造影诊断

The Angiographic Diagnosis of Liver Diseases

本文分析了原发性肝癌、肝血管瘤等9种疾病的血管造影表现;讨论了肿瘤血管、病变密度、病变染色顺序等血管造影的征象鉴别,着重讨论了病变染色顺序在肝癌和血管瘤这两种肝脏最常见病变鉴别诊断中的价值。本组材料显示:呈自内向外顺序染色者97%(32/33)见于恶性肿瘤,其中肝细胞癌占93.8%(30/32),8例直径小于3cm 的无肿瘤血管征象的小肝癌均呈自内向外顺序染色;血管瘤无1例呈此征象;呈自外向内顺序染色者可见于较大的肝癌(直径6～24cm,中位13.9cm)和血管瘤,前者有肿瘤血管,后者则无肿瘤血管,鉴别不难。

The angiographic features of 9 liver diseases containing primary hepato- cellular carcinoma(HCC),and hepatic hemangioma were analysed in this article. The signs of angiography,such as tumor vessel,lesion density,and staining sequence were discussed.The staining sequence of lesion in the differential diagnosis of HCC and he- mangioma,two most common liver diseases,was emphatically discussed.The study demon- strated that,97 percent (32/33) of the angiographic sign of the lesion staining in sequence from interior to exterior occurred in malignant tumors,in which HCC occupied 93.8 percent (30/32).All eight small HCC of a diameter smaller than 3 cm,without any tumor vessel sign presented the above mentioned sign.No hepatic hemangioma presented this sign,the angiographic sign of the lesion staining in sequence from exterior to interior occured in larger HCC (diameter 6～24 cm,mean 13.9 cm) and hemangioma.The former has tumor vessel, and the latter has none.Therfore it is not difficult to differentiate HCC from hemoangioma.
