We had performed transjugular intrahepatic portosystemic stent shunt (TIPSS) in one hundred and three patients with advanced liver cirrhosis and portal hypertension from July,1993 to January, 1995. TIPSS was carried out successfully in ninty-eight out of 103 cases and the technical success rate was 95.2%. Acute variceal bleeding was immediatly controlled and portal pressure reduced by an average of 1.36±0.02 kPa after TIPSS. The disappearance of gastric cornoary and esophageal varices, the shrinkage of spleen and the reduction of ascite were observed . Three patients died of acute liver failure and one died of variceal redbleeding within 30 days of treatment. Mild encephalohthy was obserbed in 10 cases with TIPSS. At follow-up of 1～22 months, variceal rebleeding and ascite were observed in 6 patients and stenosis of shunt was evident is 12.5% of cases by the subsequent doppler sonography. According to this result, TIPSS is an effective method for the treatment of portal hypertension.
门静脉高压症是慢性肝病的主要合并症之一，它所导致的食管胃底静脉曲张破裂出血死亡率可达30%～50%，是肝硬变患者的主要死亡原因。1概述自1945年Whipple等人倡导门体分流手术治疗门静脉高压症以来，各国学者作出了不懈努力，探求对这种顽症的治疗手段。最近20～30年在治疗方法上出现了许多革新，如内窥镜下曲张静脉硬化剂注射、曲张静脉套扎、门体静脉选择性分流（远端脾肾分流）等。应用β受体阻滞剂心得安来预防或治疗门静脉高压症引起的上消化道出血取得了肯定的疗效。小口径人工血管门静脉下腔静脉搭桥分流减少了门体分流手术后脑病的发生率，而复发出血率几乎可与传统门腔分流术相比。经颈内静脉肝内门体分流术（TIPSS）治疗急性上消化道出血的疗效十分肯定，尤其适用于手术风险大、肝功能差者。肝脏移植作为治疗终末期不可逆性肝病的成熟手段，近年来也越来越多地应用于肝硬变门静脉高压症的治疗，与其它各种治疗手段相比，肝移植可算是对门静脉高压症治疗的一种革命性的变化，一个成功的肝移植一劳永逸地解决了门静脉高压症产生的根源，使门静脉高压症得到根治。
ObjectiveTo analyze and compare the clinical and pathological characteristics of patients with porto-sinusoidal vascular disease (PSVD) and liver cirrhosis (LC), so as to provide a reference for reducing misdiagnosis and missed diagnosis. MethodsThe patients who underwent liver biopsy in the Department of Infectious Diseases in the First Hospital of Lanzhou University from January 2008 to December 2022 were retrospectively collected. The clinical, biochemical, imaging, and liver biopsy pathological data of the patients with PSVD and LC were compared. ResultsA total of 45 patients with PSVD and 48 patients with LC were included. The males to females ratio in the patients with PSVD and LC was 25∶20 and 21∶27, respectively, and the average age of the patients with PSVD was younger than that of the patients with LC (P<0.001). The patients with PSVD had overall better liver function, although the proportion of the patients with the Child-Pugh class B in the two groups was all higher, the proportion of patients with the Child-Pugh class B and the end stage liver disease model score ≥10 points in the patients with PSVD was lower (nearly three times) than those in the patients with LC (P<0.05). The initial diagnosis rate of the patients with PSVD was lower than that of the patients with the LC (6.7% vs. 95.8%, χ2=74.0786, P<0.001). The imaging findings of the patients with PSVD as compared with LC showed that the proportion of the portal hypertension was higher (33.3% vs. 39.6%) in both, but the flow velocity of the portal vein was faster (P=0.039), and the extrahepatic bile duct diameter was smaller (P=0.001). The main specific manifestations of liver biopsy histopathology in the patients with PSVD were the portal occlusion [19 (42.2%)], nodular regenerative hyperplasia [1 (2.2%)], and incomplete septal cirrhosis or fibrosis [14 (31.1%)], as well as the non-specific manifestation was the fine bile duct reaction [8 (17.8%)]. And the proportion of the patients with the liver tissue inflammatory activity grading (G) and liver fibrosis staging (S) ＞G2S2 in the patients with PSVD was lower as compared with the patients with LC [12 (26.7%) vs. 48 (100%), χ2=54.560, P<0.001]. ConclusionThe diagnosis of PSVD and LC should “seek common ground while reserving differences”, and it is necessary that a routine examination in combination with imaging manifestation and liver pathology, and should focus on a liver vascular abnormality so as to reduce a rate of misdiagnosis.
Objective To evaluate the feasibility of X-ray guided access to the extrahepatic segment of the main portal vein (PV) to create a transjugular extrahepatic portacaval shunt (TEPS). Methods 5F pigtail catheter was inserted into the main PV as target catheter by percutaneous transhepatic path under ultrasound guidance. The RUPS-100 puncture system was inserted into the inferior vena cava (IVC) by transjugular path under ultrasound guidance. Fluency covered stent was deployed to create the extrahepatic portacaval shunt after puncturing the target catheter from the IVC under the X-ray guidance, then shunt venography was performed. Enhanced CT of the abdomen helped identify and quantify the patency of the shunt and the presence of hemoperitoneum. Results The extrahepatic portacaval shunts were created successfully by only 1 puncture in 6 pigs. No extravasation was observed in shunt venography. One pig died of anesthesia on the day of operation. The extrahepatic portacaval shunts were failed in 2 pigs 3 days after the operation (one was occluded and the other one was narrowed by 80%). The extrahepatic portacaval shunts were occluded 2 weeks after the operation in the remaining 3 pigs. The shunts were out of the liver and no hemoperitoneum was identified at necropsy in the 6 pigs. Conclusion TEPS is technically safe and feasible under the X-ray guidance.
Twelve patients with multiple vavices were found adjacent to the common bile duct during cholecystectomy and exploration of the common blie duct in the presence of stones. Eleven of them were with cirrhosis. The authors recommend that retrograde cholecystecotomy, or partial cholecystestomy with electrical cauterization of the remaining gallbladder mucosa ,or even cholecystostomy be the optimal selection in the presence of a large venous channel in calot’s triangle. Multiple fine-needle puncture of the bile duct can be performed over the vascullar area until bile is aspirated; extracting the choledocholith from a transduodenal sphincterotomy is another selective maneuver; and if bleeding occurs, suturing for hemostasis can be placed on the connective tissue over both sides of the lacerated vessel instead of the wall of varices.
Portal vein blood flow is very important for the normal function of transplanted liver. The author reviewed the management methods of different portal vein thrombosis classification in the liver transplantation (LT). The prognosis of LT in the patients with Yerdel 1–3 thrombosis is similar to that the patients without thrombosis. The portal vein reconstruction of the patients with Yerdel 4 thrombosis can be realized by varicose vein to portal anastomosis, renoportal anastomosis or cavoportal hemitransposition. When anastomosis is made at the proximal side of a spontaneous shunt between the portal and cava system, the blood shunted from portal system can be reintroduced into the donor liver, which is crucial for the management of Yerdel 4 thrombosis. The establishments of artificial shunt by distal splenic vein, mesenteric vein or “multiple to one” anastomosis are effective attempts to drain the blood from portal system to the donor liver. For more severe diffuse thrombosis of portal vein system, multivisceral transplantation, including liver and small intestine, should be considered. The cases of LT in the patients with complex portal vein thrombosis are increasing, however the prognosis remains to be determined after accumulation of the cases.
ObjectiveTo investigate impact of splenectomy plus pericardial devascularization on liver hemodynamics and liver function for liver cirrhosis patients with portal hypertension. MethodsThe internal diameter, maximum velocity, minimum velocity, mean velocity, and flow volume of portal vein and hepatic artery of 42 cases of liver cirrhosis with portal hypertension were measured by Doppler ultrasonic instrument on day 1 before operation and on day 7 after operation. The free portal pressures at different phases (after open abdomen, after splenic artery ligation, after splenectomy, and after devasculanrization) were read from the disposable pressure sensor. Twenty-four healthy people through physical examination were selected as control. Results① The free portal pressure of liver cirrhosis patients with portal hypertension was decreased from (29.12±1.40) mm Hg after open abdomen to (22.71±1.21) mm Hg after splenic artery ligation, and further decreased to (21.32±1.12) mm Hg after splenectomy, but increased to (22.42±1.15) mm Hg after devasculanrization, the difference was statisticly different (all P < 0.01). ② Compared with the healthy people, for the liver cirrhosis patients with portal hypertension, the internal diameter, maximum velocity, minimum velocity, and flow volume of portal vein were significantly enlarged (all P < 0.01), which of hepatic artery were significantly reduced (all P < 0.01) on day 1 before operation; On day 7 after operation, the internal diameter of portal vein was significantly reduced (P < 0.01), the maximum velocity, minimum velocity, and mean velocity of portal vein were significantly enlarged (all P < 0.01), but the internal diameter of hepatic artery was significantly reduced (P < 0.01), the maximum velocity, minimum velocity, mean velocity, and flow volume of hepatic artery were significantly enlarged (all P < 0.01). For the liver cirrhosis patients with portal hypertension, compared with the values on day 1 before operation, the internal diameter and the flow volume of portal vein were significantly reduced (all P < 0.01) on day 7 after operation; the internal diameter, maximum velocity, minimum velocity, mean velocity, and flow volume of hepatic artery were significantly enlarged (all P < 0.01) on day 7 after operation. ③ The Child-Pugh classification of liver function between before and after surgery had no significant difference (χ2=1.050, P > 0.05). ④ No death and no hepatic encephalopathy occurred, no thrombosis of splenic vein or portal vein was observed on day 7 after surgery. Conclusionsplenectomy plus pericardial devascularization could decrease portal vein pressure and reduce blood flow of portal vein, while increase blood flow of hepatic artery, it doesn't affect liver function.
【Abstract】 Objective To study liver regeneration of the non-ligated liver lobes following portal branch ligation (PBL). Methods Sixty male Wistar rats were randomly divided into PBL group and sham operation (SO) group. Under ether anesthesia, the rats were subjected to PBL and sham operation, respectively. The animals were sacrificed on the 1st, 2nd, 3rd, 7th and 14th day respectively. The blood sample was collected from heart and the livers were harvested to determine serum alanine aminotransferase (ALT) levels and total liver weight, respectively. The hepatic histopathology was studied through light microscopy. The number of liver cell nuclear mitosis index was counted. The number of proliferative cell nuclear antigen (PCNA) index was counted by immunohistochemistry. The hepatic ultrastructural changes were studied under electron microscope. Results ①Elevated serum ALT level was observed in the first postoperative day in PBL group compared with SO group (P＜0.01)， but began to recover in the second day. ②No significant total liver weight change in PBL group and SO group were found. ③Liver cell nuclear mitosis index and PCNA index were markedly increased in PBL group compared with SO group in day 1-3 postoperative day (P＜0.01). It reached the peak in the second day and decreased slightly in the 3rd day, but still higher than SO group, then gradually return to normal lately. Conclusion The ligation of left portal branch can induce active regeneration of hepatic cell of non-ligated liver lobes in rats. The regeneration of non-ligated liver lobes may restore previous total liver weight. The ligation of 75% portal branch does not affect liver function and may be safely performed. The portal branch ligation in rats may be used as an animal model in study of liver regeneration.
