| PURPOSE : To describe the sonographic findings of the valve in the internal jugular vein in normal children.
MATERIALS and METHODS : Seventy children (5-15 years, average age 10.8 years, 36 boys and 34 girls) were recruited
for the study. The number of cusps, length and insertion sites of the valve in the internal jugular vein was examined.
Sex differences were investigated, in addition to the symmetry of the valves found in both of the veins.
RESULTS : In all children, valve was found in either one or both internal jugular veins. Sixteen percents of the children
had valve on one side only, while eighty four percents showed on both sides. All the one side were found on
the right side only. Nine percents of the valves in the internal jugular veins of the children were bicuspid and
ninety one percents were unicuspid. The length of the cusps was on the average, 7.59±2.77 mm. The insertion
of the cusps was on the average, 6.75±2.59 mm(range: 0-12.0 mm), proximal to the confluence of the subclavian
and internal jugular veins to form the brachiocephalic vein. There was no significant statistical difference of
the number of cusps, length and insertion sites of the valves on both sides and sex distinction.
CONCLUSION : A valve in internal jugular vein is identified in all cases on ultrasonography. There was no significant statistical
difference of the number of cusps, length and insertion sites of the valves on both sides and sex distinction. |
