The catheters wereconnected with implantible drug delivery system (IDDS)implanted in the skin of abdominal wall (adjacent to theincision cut). After operation, portovenography was doneand desired film were taken, then the radiologicalcharacteristics of portovenous system were analyzed.Resulte Satisfactory radiological manifestation ofpertovenous system was obtained. The main characteristicsof pertovenous system were: leaf-like sign caused byproliferation of small vessels near the major intrahepaticportal branches, portovenous branches stretched into the PHC lesion to participate its blood supply, thread-like sign,crab-like sign and goblet-rim sign or serpentine head signbecause of partial or total cancerous obstruction of portalveins, and manifestation of portal venous hypertensionconcomitant with PHC.Conclusion Radiological study of portal system of PHC isnot only useful to eonsummate the diagnosis of PHC, butalso helpful to direct the intervening treatment of it.展开更多
