ObjectiveTo summarize clinical applications of inferior right hepatic vein (IRHV) in liver surgery and to provide a basis for clinical applications of IRHV.MethodThe relevant literatures about clinical applications of IRHV in liver surgery in recent years were reviewed.ResultsAs a kind of short hepatic veins, the IRHV directly flowed into the inferior vena cava, often accompanied by the portal vein of the segment Ⅵ. The occurrence rate of IRHV was 80%–90% by the autopsy examination, while which was 10%–30% by the imaging examination. The caliber of IRHV was 0.22–0.95 cm, and its caliber was negatively correlated with the caliber of right hepatic vein. The IRHV played a great role in the classification and treatment of the Budd-Chiari syndrome. According to the Couinaud liver classification method, the IRHV mainly drained the blood of segment Ⅵ. The existence of IRHV expanded the indications of hepatectomy. The reconstruction of IRHV in the liver transplantation could not only reserve the function of donor liver, but could compensatively drain the corresponding liver areas if the acute occlusion of other major hepatic veins happened.ConclusionsIRHV has some important clinical significances in liver surgery. Fully studying course characters and adjacent relationship of IRHV can not only avoid injury during surgery, but also provide a new treatment idea for related liver diseases.
It is very important to develop and revise expert panel consensus on Chinese patent medical clinical application. The contents of the expert panel consensus include determination of the subject, clarity of the application scope, indications, dosage and administration, and safety of Chinese patent medicine. In the process, clinical researchers establish project team, formulate clinical management questions, select the outcome index, retrieve and make the evidence, and develop expert consensus with consensus methods strictly according to the requirements of methodology.
