Advances in diagnosis and treatment of portal venous thrombosis

Portal vein thrombosis (PVT) is one of the common complications of liver cirrhosis, which can further increase portal vein pressure and aggravate liver function decompensation. However, due to the insidious onset and atypical symptoms, the importance of PVT has been neglected in clinical work for quite a long time. With the development of clinical diagnostic technology, the detection rate of PVT has increased year by year. At present, the well-established treatment methods for PVT include anticoagulant therapy, interventional therapy, and surgical treatment. However, the optimal choice for PVT treatment remains unclear. In this paper, we briefly review the recent progress in the diagnosis and treatment of PVT in order to provide a theoretical reference for the refined clinical management of patients with PVT.

Risk factors for nontumoral portal vein thrombosis in patients with liver cirrhosis

AIM: To identify the risk factors for nontumoral portal vein thrombosis (PVT) in patients with liver cirrhosis, and analyze the risk factors influencing the origin of PVT.

METHODS: We performed a retrospective study of 171 cirrhotic patients who were diagnosed with the disease at our hospital between September 2013 and December 2014. CT and color Doppler ultrasound were used to diagnose PVT. Of the patients included, 34 had PVT (experiment group), and 137 had not (control group). We collected the clinical features and laboratory indexes of the two groups. Logistic regression model (Wald test) was used to screen independent risk factors. The diagnostic performance of each risk factor was determined by plotting the ROC curve and determining the optimal threshold.

RESULTS: D-dimer (DD) (OR = 12.021, P = 0.001), width of main portal vein (OR = 28.574, P = 0.001), and portal vein velocity flow (OR = 19.568, P = 0.002) differed statistically between the two groups. Unconditional Logistic regression analysis indicated that DD and width of main portal vein were independent risk factors for PVT in cirrhosis patients, and their area under the curve was 0.669 and 0.742, respectively.

CONCLUSION: Width of main portal vein and DD are independent risk factors for PVT in cirrhosis patients. Wider diameter of main portal vein and higher DD are associated with a higher incidence of PVT.
