Summary

This study used ultrasound to measure the portal vein in living adults, finding its size varies significantly with age and sex. These echography measurements provide a baseline for understanding portal vein anatomy in vivo.

Area of Science:

  • Medical Imaging
  • Vascular Anatomy
  • Diagnostic Ultrasound

Background:

  • Traditional portal vein descriptions rely on cadaveric dissections.
  • Echography offers a non-invasive method to study vascular structures in living subjects.

Purpose of the Study:

  • To establish normative measurements of the portal vein in living individuals using ultrasound.
  • To investigate the influence of age and sex on portal vein dimensions.

Main Methods:

  • A standardized echography methodology was applied by three ultrasonographers.
  • Sixty volunteers (31 male, 29 female, aged 11-82) were studied.
  • Measurements included transverse diameter and length of the portal vein.

Main Results:

Related Experiment Videos

  • The average transverse diameter of the portal vein was approximately 9.05 mm (range 5-16 mm) at the origin and 9.16 mm (range 6-16 mm) at the end.
  • Portal vein length averaged 58.0 mm, with significant variations observed based on age and sex.
  • In 3.3% of cases, the portal vein bifurcated before entering the liver.

Conclusions:

  • Ultrasound provides valuable in vivo data on portal vein dimensions.
  • Portal vein size demonstrates significant variability influenced by age and sex.
  • These findings contribute to a better understanding of normal portal vein anatomy in living adults.
