Abstract |
Thirty one cases of congenital heart disease with suspicious splenic anomaly were prospectively
studied at Seoul National University Children’s Hopsital from October, 1986 to February, 1988 in
order to determine the sensitivity and the specificity of various non-invasive diagnostic methods for
splenic status. In most cases, splenic status was confirmed by abdominal aortography. Each case had
chest X-ray, abdominal X-ray, bronchus tomography, electrocardiogram, echocardiography, abdomi-
nal ultrasound examination, peripheral blood smear for Howell-Jolly body and radioisotope spleen
selective scan using technetium.
On the basis of aortographic findings and, other findings if necessary, splenic status was classified
into 1) asplenia, 2) polysplenia, 3) normal spleen, 4) mirror image spleen.
Radioisotope scan and abdominal ultasound examination were very sensitive and specific to detect
asplenia, normal and mirror image spleen. But neither of them were sensitive to find polysplenia. In
contrast, left isomerism on bronchus tomography and inferior vena cava interruption were good
indicator of polysplenia. Relative position of inferior vena cava and aorta at 12th thoracic vertebrae
level was neither sensitive or specific to asplenia. Three fourth of asplenia showed Howell-Jolly body.
P wave axis on electrocardiogram was not helpful to define splenic status. Simple chest and
abdominal X-ray were not helpful either.
There was no single non-invasive diagnostic method applicable to all splenic status, but two or
more methods will make accurate diagnosis of splenic status. |
