目的：旨在了解门脉分流程度。方法：对３５例肝硬化和１２例非肝硬化患者，用９９ｍＴｃＭＩＢＩ经直肠注入，测定心肝核素显影比值（Ｈ／Ｌ）。结果：按ＣｈｉｌｄＰｕｇｈ分类的肝硬化各级Ｈ／Ｌ值，分别与对照组比较，差异均有显著性（Ｐ＜０．０１）；７例肝硬化和４例非肝硬化患者，术中所测的门脉压力与Ｈ／Ｌ值呈正相关。胃镜下食管静脉曲张度不同的Ｈ／Ｌ值亦不同，重度曲张者１３例，Ｈ／Ｌ值均＞１．００，其中，出血者１０例。结论：本方法是无创性诊断门脉高压可靠安全的新手段，并将Ｈ／Ｌ值＞１．００的肝硬化患者，作为判定食管静脉曲张有出血危险的一项指标。
Purpose: To understand the degree of portal shunt. Methods: Thirty-five patients with cirrhosis and 12 patients with non-cirrhosis were injected with 99mTcMIBI into the rectum to determine the H / L ratio. Results: The values of H / L at all levels of cirrhosis according to Child-Pugh classification were significantly different from those in control group (P <0.01). Seven patients with cirrhosis and 4 patients with non-cirrhosis, The measured portal pressure and H / L values were positively correlated. Gastroscopy esophageal varicosity different H / L values are different, severe varicose in 13 cases, H / L values were> 1.00, of which 10 cases of bleeding. Conclusion: This method is a new noninvasive method to diagnose the safety of portal hypertension. Patients with liver cirrhosis with H / L value> 1.00 may be used as an index to determine the risk of bleeding in esophageal varices.
