作者用B超多普勒复合装置测定了62例肝癌患者手术前后的入肝血流量。结果:①无门脉主干癌栓的肝癌患者术前肝固有动脉血流量和门静脉血流量均大于对照组;②肝固有动脉结扎加栓塞术后,门静脉血流量增加;③右半肝切除术后肝固有动脉血流量的减少较肝右动脉结扎加栓塞术后更为明显;④门静脉主干癌栓经治疗(肝动脉和门静脉灌注化疗)缩小后,门静脉血流量增加,肝固有动脉血流量减少;⑤门静脉血流增加的量与肝固有动脉血流减少的量存在正相关。提示肝癌既保持肝动脉和门静脉双重供血;也存在广泛的肝内动脉侧枝循环和敏感的肝内血流调节系统。
The authors measured the hepatic blood flow before and after surgery in 62 patients with hepatocellular carcinoma using a B-ultrasound combined device. RESULTS: 1 The preoperative hepatic arterial blood flow and portal vein blood flow in patients without primary portal vein tumor embolus were greater than those in the control group; 2 Hepatic proper arterial ligation and embolization increased portal vein blood flow; 3 Right hemihepatectomy The decrease of hepatic arterial blood flow was more obvious than that of right hepatic artery ligation and embolization. 4 After portal vein cancer thrombus was treated (hepatic artery and portal vein chemotherapy), the blood flow of portal vein increased, and the blood flow of hepatic proper artery decreased. The amount of increase in portal vein blood flow is positively correlated with the decrease in blood flow in the proper hepatic artery. It is suggested that hepatocellular carcinoma not only maintains hepatic arterial and portal venous blood supply, but also extensive intrahepatic artery collateral circulation and sensitive hepatic blood flow regulation system.
