Perioperative plasma amino acid spectrum (PAAS) was analysed in 10 portal hypertensive patients (PH) receiving portacaval H graft shunt (D=8mm) and 10 gastroenteropathic patients (GE) without hepatic disease.In both groups, arterial,peripheral and hepatic venous blood was drawn for analysis immediately pre and post operation on the table, postoperative day 1 and 3, respectively.It was found that amino acid concentration decreased in both groups but in PH group it was changed significantly.The preoperative branched chain amino acid (BCAA)/aromatic amino acid (AAA) ratio was less than 2 in the PH group and larger than 3 in the GE group after operation. The ratio did not change significantly in both groups after operation. In the PH group, the pre and post operative BCAA and AAA level in hepatic vein was higher than in other sites. The immediately BCAA and AAA levels were lower than preoperative levels. Among the changes the postoperative decrease of VAL and LEU was significant.Both BCAA and AAA reached preoperative level at postoperative day3. The results reveal that small diameter portacaval shunt has no significant influence on PAAS. The temporary decrease of amino acid levels postoperatively may be related to the stress of operation and liver impairement.

作者于1994年4月至1995年5月对10例肝硬变门静脉高压和10例无肝病胃肠手术患者进行了血浆氨基酸谱检测。10例门静脉高压患者行8mm口径人工血管门腔搭桥分流术。分别于分流术前、术后即刻、术后1天、术后3天测定周围动脉、周围静脉、门静脉及肝静脉血浆氨基酸谱,胃肠手术组则于手术开始及术后3天测定。结果显示:胃肠组与分流组术后氨基酸水平均比术前下降,但分流组下降明显。支链氨基酸与芳香氨基酸之比(BCAA/AAA)在分流术前小于2,对照则大于3,术前术后两组变化均不明显。在分流组患者肝静脉血中的BCAA及AAA含量无论手术前后均高于其它部位;分流术后即刻BCAA及AAA均比术前减少,其中BCAA中缬氨酸、亮氨酸减少明显。术后3天BCAA和AAA恢复至术前水平。提示:小口径门体分流术对患者氨基酸谱变化无明显影响。术后氨基酸暂时下降可能与手术应激及肝功受损有关

Objective To evaluate the hepatic perfusion changes after portosystemic shunt in cirrhosis patients with portal hypertension by means of CT perfusion imaging. Methods Fifteen cirrhosis patients with history of upper gastrointestinal bleeding were included in this study, 13 cases with Child A liver reserve, and 2 cases with Chlid B. All patients underwent CT hepatic perfusion within 2 weeks before and after portosystemic shunt operation respectively. The perfusion parameters included hepatic blood flow (HBF), hepatic blood volume (HBV), mean transit time (MTT), permeability surface (PS) and hepatic perfusion index (HPI). The results of parameters measured were correlated with the portal vein pressure measured before and after portal-systemic shunt during the operation. Results The hepatic perfusion parameters before/after portal-systemic shunt were: HBF: 120.0/110.1 ml/(min·100 ml) (P>0.05), HBV: 17.9/20.9 ml/100 ml (P>0.05), MTT: 13.6/14.2s (P>0.05), PS: 35.8/37.5 ml/(min·100 ml) (P>0.05) and HPI: 0.21/0.42 (P<0.01). The portal venous pressure before and after shunt were 41.7/28.1 cm H_2O (P<0.001), respectively. Conclusion CT perfusion imaging showed that HBF decreased in cirrhosis patients and HPI increased significantly after portosystemic shunt, which indicated a decrease of portal vein perfusion. CT perfusion scan is useful to access the hemodynamic changes in cirrhosis patients with portal hypertension.

目的应用多层螺旋CT观察肝硬变门脉高压患者门腔静脉分流后肝脏血流灌注的改变。方法肝硬变门静脉高压合并上消化道出血患者15例。肝功能Child分级A级13例、B级2例。在分流术的前后两周之内各进行一次CT血流灌注扫描。测量每一例患者的肝血流量(HBF)、肝血容量(HBV)、平均通过时间(MTT)、毛细血管通透性(PS)和肝动脉灌注指数(HPI)。所测参数与术中测量的分流前后门静脉压力作对照观察。结果门腔静脉分流前/后的各灌注参数为:HBF120.0/110.1ml/(min·100ml)(P>0.05)、HBV17.9/20.9ml/100ml(P>0.05)、MTT13.6/14.2s(P>0.05)、PS35.8/37.5ml/(min·100ml)(P>0.05)、HPI0.21/0.42(P<0.01)。门腔静脉分流前/后的门静脉压力为41.7/28.1cm水柱(P<0.001)。结论肝脏CT灌注成像显示肝硬变门脉高压患者的肝血流量下降,肝动脉指数在分流术后明显增高,提示门静脉灌注量降低。CT血流灌注扫描助于了解肝硬变门脉高压的血流动力学改变。
