Introduction Acute appendicitis is the most common reason for emergency abdominal surgery in the pediatric population. Ultrasound (US) is a widely used modality to diagnose acute appendicitis. The aim of this study was to evaluate the effectiveness of portal vein diameter and flow velocity in acute appendicitis diagnosis. Methods Portal vein diameter and flow velocity were measured in children who were referred to radiology with a clinical diagnosis of acute appendicitis. The largest appendix diameter and leukocyte count of the patients were recorded. A control group was created which consisted of healthy children, and their portal vein diameter and flow velocities were also measured. Results The median age of the population was 10 years (range, 3–17 years). Mean portal vein diameter was 7.53 ± 1.55 mm in the control group, 7.92 ± 1.88 mm in the other diagnosis group, and 8.76 ± 1.91 mm in the acute appendicitis group. Mean portal vein diameter was significantly higher in the acute appendicitis group (p = 0.001). Median portal vein flow velocity was 17 cm/s (10–29 cm/s) in the control group, 18.3 cm/s (8–27 cm/s) in the other diagnosis group, and 20.5 cm/s in the acute appendicitis group. Median portal vein flow velocity was significantly higher in the acute appendicitis group (p = 0.00). Conclusion Detecting an increase in portal vein diameter and/or flow velocity in equivocal cases may support other clinical signs associated with acute appendicitis. Portal vein diameter and flow velocity can serve as additional diagnostic markers in acute appendicitis cases.

Abstract Background: Cirrhotic patients with portal vein thrombosis (PVT) may have a high risk of hepatic decompensation and increased mortality. This study aimed to investigate if increased portal vein diameter is associated with PVT development.Methods: A total of 174 cirrhotic patients were enrolled between February 1 and August 31, 2017. All participants were divided into PVT (n=62) and non-PVT (n=112) groups based on the thrombus that was detected by ultrasonography and confirmed by computed tomography angiography (CTA).Results: The study participants, aged 54.7±10.5 years (PVT) and 55.8±11.6 years (non‑PVT), were included in this analysis. The Child-Pugh score of PVT or non‑PVT was 6.6±1.3 and 5.8±0.9, respectively. Hepatitis B virus (HBV) is the primary etiological agent of cirrhosis. Logistic regression, receiver operating characteristic (ROC), and nomograph analysis designated portal diameter as the strongest independent risk factor for predicting PVT development (odds ratio (OR): 3.96, area under the ROC curve (AUC): 0.88;P<0.01), and the cutoff with predictive value for PVT development was >12.5 mm. No differences were observed in the overall survival (OS) in cirrhosis with or without PVT or stratifying on portal diameter based on the cutoff value.Conclusions: Increased portal diameter is associated with an increased risk of PVT development. Patients with cirrhosis and increased portal diameter are a high-risk subgroup that may need thromboprophylaxis.

 Introduction: Upper Gastro-intestinal endoscopy is considered the best screening tool for varices in cirrhotic patients. It is still an expensive, invasive tool, has poor compliance and not routinely available in every hospitals in Nepal. This study was undertaken to establish the role of portal vein diameter and spleen size by ultrasonography in predicting gastro-esophageal varices.Method: One hundred and fifty patients with clinical features, laboratory and sonological findings suggestive of cirrhosis of liver and endoscopic evidence of portal hypertension were included in the study. Ultrasonography assessments of portal vein diameter and spleen size alongside endoscopy for detection of varices were done.Result: Average portal vein diameter of patients without gastro-esophageal varices was 10.800 ± 1.1402 mm, while it was 13.731 ± 1.061mm in patients with varices(p<0.001). Average spleen size of patients without varices was 12.67 ± 2.35 cm and with varices was 15.367 ± 1.210 cm (p < 0.001). There was 92.72 % sensitivity and 90 % specificity for prediction for presence of esophageal varices when the cutoff value for portal vein diameter was 12.25 mm. There was 94.5 % sensitivity and 75 % specificity for prediction for presence of esophageal varices when the cutoff value for spleen size was 13.9 cm.Conclusion: Ultrasonography of portal vein diameter and spleen size is a reliable non invasive tool in predicting the presence of gastro-esophageal varices in patients with liver cirrhosis. With increase in portal vein diameter and spleen size, risk of formation of gastro-esophageal varices also increases and positive correlations exist between them. Nepalese Journal of Radiology, VOL 4 No. 2 ISSUE 7 July-December, 2014: 6-14
