肝癌伴肝动静脉短路的DSA成像技术

The DSA imaging technique of hepatocellular carcinoma with arterio-venous fistula

目的 :探讨肝癌伴肝动静脉分流的DSA成像技术。方法 :收集 1997年～ 2 0 0 0年 2 40例肝癌介入治疗中的 32例肝癌伴肝动静脉短路分流 ,进行DSA成像技术研究。在充分展示肝动静脉分流通道后进行封堵 ,再行肝癌的栓塞治疗。结果 :32例肝癌伴肝动静脉瘘 ,其中 12例见明显的瘘道 ,17例见分流通道纤细 ,3例无确切的分流通道。结论 :合理注射参数、恰当体位。

Objective:To study the DSA imaging technique of hepatocellular carcinoma (HCC) with arterio venous fistula. Methods: From 1997 to 2000,240 patients of HCC undergoing interventional therapy were collected.From which 32 cases with arterio venous fistula and their DSA imaging techniques were analyzed.After the clear demonstration of arterio venous fistula,fistula blockage and HCC chemoembolization were made subsequently.Results:Of 32 cases of HCC with arterio venous fistula,12 cases revealed distinct fistula, 17 showed fine shunt and 3 indefinite fistula.Conclusion:The detectability of hepatic arterio venous fistula can be improved using optimal injection parameters, proper body posture,superselective contrast angiography and prolongation of acquisition time.
