“…The incidence of portal vein tumor thrombosis (PVTT) is 44-62.2% (3). Once PVTT occurs, it often progresses rapidly and can cause portal hypertension, hepatocellular jaundice, intractable ascites and portal vein thrombosis, The treatment of portal thrombosis is very difficult, which can seriously affect the prognosis of the patients (4). The median survival time of patients with HCC and PVTT is reported to be only 2.7 months (3).…”

Background: Hepatic portal vein collateral circulation plays an important role in maintaining the perfusion of hepatic portal vein. However, at present, there is little research on collateral circulation of hepatic portal vein. Our study aims to analysis the imaging types and clinical value of hepatocellular carcinoma (HCC) with portal vein tumor thrombus (PVTT) invading and completely blocking different branches of portal vein, secondary to hepatic portal vein collateral circulation. Methods: This study retrospectively analyzed Hepatocellular carcinoma (HCC) with PVTT diagnosed with enhanced CT examination of the upper abdomen in our hospital from May 2020 to October 2021. The inclusion criteria for patients were the following: (I) ultimately diagnosed with HCC, (II) accompanied by complete obstruction of the main portal vein or left/right branches, and (III) with collateral circulation of the hepatic portal vein established. All images were postprocessed by multiplanar reconstruction (MPR), maximum intensity projection (MIP), and other reconstruction techniques to obtain images of the abnormal portal vein system and the collateral vessels running toward the hepatic portal veins. Three physicians jointly judged the imaging anatomical classification of each collateral vessel. The qualitative variables were compared by chi-squared test.Results: A total of 125 hepatic portal vein collateral vessels were observed in MPR and MIP reconstruction images of 71 patients with portal vein cancer thrombosis with established hepatic portal vein collateral circulation. Common hepatic collateral branches in patients with PVTT mainly include the biliary collateral branch, gastric collateral branch, mesenteric collateral branch, accessory portal vein system and the splenic branch. The incidence rate was respectively 77.5%, 36.6%, 32.4%, 28.2%, 1.41%. Conclusions:The correct understanding of the imaging anatomical classification of the collateral vessels of the hepatic portal vein can provide clinicians with more information for diagnosis and treatment planning.

Background Lung cancer is one of the most commonly diagnosed malignancies worldwide, and the occurrence of venous thrombosis in combination with lung cancer seriously affects the survival prognosis of patients with lung cancer. This study aimed to delineate the publication status and trends in the literature related to thrombosis in lung cancer and to explore hotspots in research by conducting a bibliometric analysis. Methods Using the Web of Science database as the data source for bibliometric analysis, we searched the published research literature related to thrombosis in lung cancer from 1942 to 2022. Bibliometrix and VOSviewer were used to analyze key bibliometric indicators, including trends in the number of annual publications, countries, journals, author contributions, and research hotspots. Results A total of 378 papers related to thrombosis in lung cancer were screened, including 349 original articles and 29 reviews. The number of publications has increased rapidly in the last 20 years, and China and the United States have the largest number of publications. In the analysis of authors and journals, we found that the distribution of Chinese authors is relatively high in terms of the number of publications and their influence, while the journal sources are mainly dominated by oncology and thrombosis research journals. The analysis of the top 10 highly cited papers revealed that several studies involved the relationship between cancer and venous thrombosis and the exploration of cancer-related thrombotic risk factors. The keyword analysis showed that the papers mainly focused on the exploration of risk factors, in which related genes represented by ROS1 and immunotherapy gradually appeared in research on predicting thrombosis in lung cancer. Conclusions Research on thrombosis in lung cancer has developed rapidly in the past 20 years, with the largest number of studies coming from China. The main research hotspots are the exploration of risk factors, among which the association between related genes represented by ROS1, immunotherapy, and thrombosis in lung cancer-related events has brought us new thinking in the prevention of thrombosis in lung cancer.
