The background of this study is the high prevalence of upper gastrointestinal bleeding in patients with cirrhotic portal hypertension. This can lead to significant morbidity and mortality, making early detection and prevention crucial. Multi-slice spiral computed tomography (CT) perfusion imaging is a non-invasive diagnostic tool that can provide detailed information on blood flow and vessel characteristics in the liver and portal vein. However, its predictive value for upper gastrointestinal bleeding in patients with cirrhotic portal hypertension has not been fully explored. The present status of the study is to investigate the predictive accuracy of multi-slice spiral CT perfusion imaging for upper gas
The motivation for this research is the high prevalence of upper gastrointestinal bleeding in patients with cirrhotic portal hypertension, which can lead to significant morbidity and mortality. Early detection and prevention are crucial for improving patient outcomes, but current diagnostic tools have limitations. Multi-slice spiral CT perfusion imaging is a non-invasive diagnostic tool that offers detailed information on blood flow and vessel characteristics in the liver and portal vein. However, its predictive value for upper gastrointestinal bleeding in patients with cirrhotic portal hypertension has not been fully explored. Therefore, this study aims to investigate the predictive accuracy of multi-slice spiral CT perfusion imaging and identify specific parameters that may have high predictive values. The results of this study could improve early detection and prevention of upper gastrointestinal bleeding in patients with cirrhotic portal hypertension, ultimately leading to better patient outcomes and quality of life.
To investigate the predictive accuracy of multi-slice spiral CT perfusion imaging for upper gastro
The research methods of this study involved a retrospective analysis of 62 patients with cirrhotic portal hypertension and 28 healthy individuals who served as controls. The disease group was further divided into two subgroups: Group A (n = 27, bleeding) and group B (n = 35, no bleeding). All participants underwent multi-slice spiral CT perfusion imaging at the hospital. The researchers compared various parameters such as liver blood flow, vein size, number of blood vessels, and blood vessel area between the two groups using statistical analysis. They calculated the OR to determine the strength of the association between these parameters and upper gastrointestinal bleeding. They also created a graph to compare the predictive value of different factors for bleeding. The research methods used in this study allowed the researchers to identify factors associated with bleeding and evaluate the potential of multi-slice spiral CT perfusion imaging for predicting upper gastrointestinal bleeding in patients with cirrhosis and portal hypertension.
The research results showed that multi-slice spiral CT perfusion imaging had a significant predictive value for upper gastrointestinal bleeding in patients with cirrhotic portal hypertension. The researchers found that the vascular area, number of vascular cross-sections, and GCVD had high predictive values for bleeding, with the vascular area having the best predictive power. They also identified several factors associated with upper gastrointestinal bleeding, including portal vein levels, hepatic artery perfusion index levels, portal vein diameter, splenic vein diameter, and the number and area of blood vessels. The statistical analysis revealed a strong link between GCVD, number of blood vessels, blood vessel area, and upper gastrointestinal bleeding. Overall, the study suggests that multi-slice spiral CT perfusion imaging can help predict upper gastrointestinal bleeding in patients with cirrhosis and portal hypertension, and blood vessel area may be the strongest predictor among the evaluated parameters.
The research conclusions of this study suggest that multi-slice spiral CT perfusion imaging can predict upper gastrointestinal bleeding well in patients with cirrhosis and portal hypertension. The study found that the vascular area, number of vascular cross-sections, and GCVD had high predictive values for bleeding, with the vascular area having the best predictive power. The researchers also identified several factors associated with upper gastrointestinal bleeding in this patient population. Overall, the study highlights the potential of multi-slice spiral CT perfusion imaging as a useful tool for predicting upper gastrointestinal bleeding in patients with cirrhosis and portal hypertension. These findings may inform clinical decision-making and improve patient outcomes in this population.
That future research can build upon these findings to further validate the use of multi-slice spiral CT perfusion imaging for predicting upper gastrointestinal bleeding in patients with cirrhosis and portal hypertension. Future studies can explore the optimal cutoff values and diagnostic performance of different parameters identified in this study. Additionally, studies can investigate the potential of other imaging modalities or biomarkers for predicting upper gastrointestinal bleeding in this patient population. These efforts may further improve the management and outcomes of patients with cirrhosis and portal hypertension who are at risk of upper gastrointestinal bleeding.
