摘　　要：目的探讨酒精性肝硬化门静脉高压侧支循环的形态和静脉引流特点。方法回顾性分析63例酒精性肝硬化和乙肝肝硬化门静脉高压患者的CT门静脉成像(CTPV)表现,对比分析其食管静脉曲张、胃静脉曲张、胃(脾)-肾分流及附脐静脉的特点。结果与乙肝肝硬化相比,酒精性肝硬化的食管静脉曲张(EV)以管旁静脉曲张、非前支优势型供血较常见,较多伴附脐静脉曲张,胃(脾)-肾分流以直径大于5cm居多。上述2型肝硬化胃静脉曲张的血液供应差异无统计学意义。结论酒精性肝硬化的侧支循环的血供特点对临床了解患者门-体侧支循环的曲张静脉情况、选择治疗方案可提供参考信息。Objective To investigate the characteristics of portal systemic collateral circulation in patients with alcoholic cirrhosis by CT portal venography.Methods Sixty-three patients with alcoholic or HBV cirrhosis were analyzed retrospectively. The characteristics of esophageal varices, gastric varices, gastrorenal and/or splenorenal varices and paraumbilical varices were studied and compared. The esophageal varices were classfied into periesophageal and paraesophageal varices according to their location. Results Compared to the HBV cirrhosis, the esophageal varices in alcoholic cirrhosis were more prone to locate on paraesophageal site and its blood supply often came from non-anterior branches dominant of the left gastric vein. The diameter of the gastrorenai/spleenrenal varices was often larger than 5 cm and the paraumbilical varices can be seen more often in alcoholic cirrhosis. However, the blood supply of the gastric varices showed no difference between the two kinds of liver cirrhosis. Conclusion Some features of collateral circulation in alcoholic cirrhosis can be shown on CTPV. It is of important value in getting the message of the portosystemic circulation and selecting treatment of both kind of liver cirrhosis.
