Study design:

Sequential 

研究目的:

通过计算流体力学探究PSVD肝脏血流动力学特征,并比较其与肝硬化门静脉高压血流动力学的差异。  

Objectives of Study:

To explore the hepatic haemodynamics in porto-sinusoidal vascular disease through computational fluid dynamics, and compare the difference with the cirrhotic patients with portal hypertension.

药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1.根据肝活检病理结果证实没有肝硬化的存在,之后符合以下三点中任一点即可确诊: (1)存在一条门静脉高压的特异性表现; (2)存在一条PSVD组织学特异性损伤表现; (3)存在一条门静脉高压非特异性表现与一条PSVD组织学损伤非特异性表现。由于肝活检的目的是排除肝硬化,并发现细微且分布不均的PSVD组织学损伤,因此活检取得的组织条长度需>=20mm,并拥有>=10个完整的汇管区.

Inclusion criteria

1. According to the results of the liver biopsy pathology, the absence of cirrhosis is confirmed. Subsequently, the diagnosis can be made if any one of the following three criteria is met: (1) The presence of a specific manifestation of portal hypertension; (2) The presence of a specific histological lesion of PSVD; (3) The presence of one non-specific manifestation of portal hypertension and one non-specific histological lesion of PSVD. Since the purpose of liver biopsy is to exclude cirrhosis and detect subtle and unevenly distributed PSVD histological lesions, the length of the biopsy specimen must be >=20 mm and contain >=10 complete portal tracts.

排除标准:

1.影响肝静脉的疾病(如Budd-Chiari综合征); 2.引起微血管损伤的疾病(如肝结节病、先天性肝纤维化或肝窦阻塞综合征); 3.未接受肝活检或肝活检病理结果证实存在肝硬化; 4.无上腹部CTA及肝脏超声多普勒检查.

Exclusion criteria:

1. Diseases affecting the hepatic veins (such as Budd-Chiari syndrome); 2. Diseases causing microvascular damage (such as hepatic nodular disease, congenital hepatic fibrosis, or sinusoidal obstruction syndrome); 3. No liver biopsy performed or liver biopsy pathology confirming cirrhosis; 4. No upper abdominal CTA and liver Doppler ultrasound examination.
