Observation of microvascular casts of human hepatocellular carcinoma by scanning electron microscopy

摘要: The microcirculation of hepatocellular carcinomas (HCCs) and surrounding tissue was observed three-dimensionally by scanning electron microscopy vascular casts made from 10 livers at autopsy. were perfusion-washed cast with resin through both the hepatic artery portal vein branches. HCCs ranged several millimeters to 3 cm in size. A plexus proliferated around HCC nodules all cases. Both branches markedly form 5 patients. These vessels communicated directly blood sinuses as feeder vessels. cells replaced normal while maintaining liver's trabecular structure 2 At borders these HCCs, there direct communication between sinusoids tumor sinuses. Efferent tumors generally difficult identify but resembling detected one 4-mm nodule after microdissection. Thus, demonstrated be supplied not only also sinusoids. This may reasons why cancer survive margins daughter transcatheter arterial embolization HCC.
