腹壁静脉血流图与MIBI对肝硬化门脉分流检测的比较研究

本文对３８例肝硬化和１８例对照组，同步作了多普勒腹壁静脉血流图和＾９９ｍＴｃ－ＭＩＢＩ（甲氧基异晴）经直肠给药γ－照相，电子计算机检测Ｈ／Ｌ值，结果表明肝硬化患者的异常腹壁静脉血流阳性率达９４．７％，与＾９９ｍＴｃ－ＭＩＢＩ直肠给药后Ｈ／Ｌ值的阳性率（８９．４％）相近，远高于常规检查法。腹壁静脉血流指数与Ｃｈｉｌｄ－Ｐｕｇｈ分级有相关趋势。观察心得安治疗前后可显示明显改善。因而腹壁静脉血流指数及＾

COMPARATIVE EVALUATION OF THE DOPPLER ULTRASONOGRAPHY OF ABDOMINAL WALL VEIN FLOW AND 99mTC-MIBI PER RECTUM TO DETECT PORTAL HYPERTENSION IN CIRRHOSIS

n this study,the Doppler ultrasonography of abdominal wall vein flow and 99mTc-MIBI per rectum to detect portal hypertension were comparatively evaluated in 38 hepaticcirrhosis patients and 18 normal subect The results showed that:(1)There are nosignificant difference of positive percentages in Doppler ultrasonography(94.7%)and99mTc-MIBI detection(89.4%),while both are much higher than the routine examinat-ion.(2)These two motheds are also positively correlated,with Child-Pugh classificationin assessment of hepatic cirrhosi3)The decreasing index of adbominal wall veinsflow in 22 cases treated by propranolol can be determined by Doppler ultrasonoigrapy.Thus,it was suggested that Doppler ultrasonography is a simple,safe and sensitivemethod for measurement of the portal vein pressure in patients witn cirrhosis and portalhypertension
