“…They also concluded that although both age and height correlate well with portal vein diameter, cutoff values should be related to body height rather than age. 1 We have come up with the same conclusion as shown on Table 1. As stated previously, it is of utmost importance to establish the normal's first in order to recognize and monitor the abnormal.…”

“…It has been published in several studies that portal dimensions are slightly larger in men, increases slightly with inspiration, decreases with exercise and in upright position. 1,2,3,4,5 Studies in the pediatric age group are limited. In our study, measurements were taken under standard conditions: patients in supine position, while quiet breathing and at least two hours after a normal meal.…”

The assessment of portal vein size by ultrasonography is an important noninvasive investigation which supports the diagnosis of portal hypertension in children and adults. Indian data regarding normal portal vein diameter in children are sparse. Present study was undertaken to establish normal range of portal vein diameter in children in relation to age, weight and height. Material and methods: During September 2015 to May 2018, a prospective study of 148 patients was carried out in the department of paediatrics and radiology at L.G.Hospital, Ahmedabad between the age group of day 1 of life to 15 years, residing in Gujarat and adjacent areas of MP and Rajasthan. The measurement of portal vein diameter at porta made during quiet breathing in younger children and during breath-holding in older children. Neither preparation nor sedation was used. Results: Portal vein diameter highly correlated with each of the variables: age, height, weight. The correlation observed was all similar in magnitude and highly significant (P < 0.0001). Most statistically significant correlation with portal vein diameter was observed with height. The mean portal vein diameter increased with height. Conclusion: Most statistically significant correlation with portal vein diameter was observed with height. The mean portal vein diameter increased with height.

Assessment of normal portal vein diameter in children

Background and aim: The internal diameter of the portal vein varies with age and anthropometric parameters. The caliber of the normal portal vein in adults has been extensively studied but little is known about portal vein dimensions in the growing child. This study was conducted to establish standards of portal vein diameter by ultrasonography in healthy Indian children based on age, gender and anthropometric parameters. Methods: Total 306 healthy children between the age of <1 month and 12 years, visiting our outpatient departmentor accompanying their siblings were enrolled in the study. The children were distributed into ten age-groups. Each group was further divided in two subgroups based on gender. Anthropometric parameters including weight, height and chest circumference were measured.Portal vein diameter was assessed by ultrasonography. Results: The portal vein diameter increases with age, height, weight and chestcircumference. But the values are similar in boys and girls. Multiple logistic regression (adjusted Rsquare:0.922) revealed age (p=0.002), height/length (p <0.0001), weight (p=0.011), and chest circumference (p<0.0001), as independent determinants of portal vein diameter. However, height/length emerged as the most consistent determinant (coefficient of regression: 1.536; p<0.001; 95% confidence interval: 0.066-0.092). Conclusion: Our results provide a normal range of portal vein diameter according to age, gender and anthropometric parameters. We conclude that portal vein diameter strongly correlates with age and anthropometric variables like height, weight and chestcircumference,with height being the strongest determinant.

Liver and systemic hemodynamics in children with cirrhosis: Impact on the surgical management in pediatric living donor liver transplantation

et al. 2017

Cirrhosis in adults is associated with modifications of systemic and liver hemodynamics, whereas little is known about the pediatric population. The aim of this work was to investigate whether alterations of hepatic and systemic hemodynamics were correlated with cirrhosis severity in children. The impact of hemodynamic findings on surgical management in pediatric living donor liver transplantation (LT) was evaluated. Liver and systemic hemodynamics were studied prospectively in 52 children (median age, 1 year; 33 with biliary atresia [BA]). The hemodynamics of native liver were studied preoperatively by Doppler ultrasound and intraoperatively using invasive flowmetry. Portosystemic gradient was invasively measured. Systemic hemodynamics were studied preoperatively by Doppler transthoracic echocardiography and intraoperatively by using transpulmonary thermodilution. Hemodynamic parameters were correlated with Pediatric End-Stage Liver Disease (PELD) score and the histological degree of fibrosis (collagen proportionate area [CPA]). Cirrhosis was associated with a 60% reduction of pretransplant total liver flow (n = 46; median, 36 mL/minute/100 g of liver) compared with noncirrhotic livers (n = 6; median, 86 mL/minute/100 g; P = 0.002). Total blood flow into the native liver was negatively correlated with PELD (P < 0.001) and liver CPA (P = 0.005). Median portosystemic gradient was 14.5 mm Hg in children with cirrhosis and positively correlated with PELD (P < 0.001). Portal vein (PV) hypoplasia was observed mainly in children with BA (P = 0.02). Systemic hemodynamics were not altered in our children with cirrhosis. Twenty-one children met the intraoperative criteria for PV reconstruction using a portoplasty technique during the LT procedure and had a smaller PV diameter at pretransplant Doppler ultrasound (median = 3.4 mm; P < 0.001). Cirrhosis in children appears also as a hemodynamic disease of the liver, correlated with cirrhosis severity. Surgical technique for PV reconstruction during LT was adapted accordingly.
