采用~(99m)Tc-甲氧基异丁基异腈(MIBI)经直肠给药,测定51例手术前病人的心肝放射性比值(H/L),并与手术中实测门静脉压力(PVP)比较,建立推算PVP的回归方程。根据此方程测算其中12例门静脉高压症病人肝肾静脉分流术后2~3周内的门静脉压力,得出的推算值与经门静脉系统留置插管直接测压值相比较,现将结果报告如下。一、资料与方法对象:受试者为外科住院病人,共51例,实际测定63例次。
The heart-liver radioactivity ratio (H / L) of 51 preoperative patients was measured by rectal administration of 99m Tc-methoxyisobutylisonitrile (MIBI) and compared with the measured portal pressure (PVP) Calculate the PVP regression equation. Calculated according to this equation in which 12 cases of portal hypertension in patients with liver and renal venous shunt within 2 to 3 weeks after the portal pressure obtained by the estimated value and portal vein catheter indwelling direct manometry value comparison, the results are reported as follows . First, the data and methods Object: The subjects were surgical inpatients, a total of 51 cases, the actual determination of 63 cases.
