    The objective of this study is to determine the difference of the flow velocities of left and right cerebral arteries. We also studied the effect of head position to the cerebral arterial flow velocities. Eligible for inclusion in this study were 60 neonatal infants whose gestational age was 33.1 +/- 3.5 weeks and whose birth weight was 1793 613 g. The ultrasonographic examinations were performed in the first and second weeks after birth. In an axial scan through a temporal window, the Doppler sample volume was positioned at the center of the M1 portion of the middle cerebral artery and the flow velocity curve was detected. No statistical difference was seen in the flow velocities between the left and right middle cerebral arteries. However, the flow velocities in the upper side were significantly higher than those in the lower side. RI in the upper side was significantly smaller than that in the lower one. This change of flow velocities stabilized in 5 min after the head was turned upside down. The effect of head positioning to the intracranial blood flow must be considered when cerebral ultrasonography of neonates is performed. (C) 2002 Elsevier Science Ireland Ltd. All rights reserved.

    The objective of this study is to determine the causes of asymmetry of the lateral ventricles in neonates. We also studied the effect of head position and the relationship of body weight at birth in regard to lateral ventricular size. Eligible for inclusion in this study were 60 neonatal infants whose gestational age was 33.1+/-3.5 weeks and whose birth weight was 1793 613 g. Ultrasonographic examinations were performed at the first and the second weeks after birth. In parasagittal and coronal scans through the posterior horn of the lateral ventricle, the lateral ventricle was traced and its area was measured. We found no significant variation of ventricular size in relation to body weight at birth. The left ventricular size was larger than the right one. The difference of the left and right ventricular sizes was partially effected by head position. The ratio of left to right lateral ventricular sizes showed a very wide distribution. We considered that ventricular asymmetry is not pathological, but due to individual differences. (C) 2002 Elsevier Science Ireland Ltd. All rights reserved.

    To compare the flow pattern of the superior caval vein (superior vena cava; SVC) after catheter therapy with that after open-heart surgery, we examined the flow velocity curves of the SVC in 10 pediatric patients who underwent catheter closure of artial septal defect (ASD) and in 20 pediatric patients who underwent open-heart surgery. We used pulsed Doppler examinations to record the velocity curves. On the velocity curve of the SVC in children after open-heart surgery, the velocity in systole was lower than that in diastole, which is contrary to the normal pattern. The velocity in systole increased more than that in diastole during inspiration, which also differs from the normal pattern. In contrast, the velocity curve of the SVC in patients after catheter therapy showed a normal pattern. The change of flow velocity during respiration became smaller after treatment in the surgery group, although it did not change after treatment in the catheter group. These results might indicate less reserve ability in the right atrium in patients who undergo open-heart surgery. ASD closure by catheter is useful not only for its economy and noninvasiveness but also for its potential to contribute conservation of right atrial function.

    To investigate the pattern of flow in the superior caval vein in children after open heart surgery, we examined the flow velocity curves in 37 patients who had undergone surgical correction of either ventricular or atrial septal defects. The control group consisted of 64 age-matched children. We used pulsed Doppler examinations to record the velocity curves. We measured the highest and lowest peak flow velocities during systole and diastole, and calculated ratios for the various measurements. We found that the velocity of the wave in systole is lower than that of the wave in diastole in the postoperative patients, which is contrary to the normal pattern. The velocity in systole increases more than that in diastole during inspiration, which is also different from the normal pattern. The change in pattern of flow velocity curve during respiration was smaller in patients after surgery than in normal subjects, which might indicate that there is less reserve ability in the right atrium in postoperative patients.

    The relationships between age, aortic diameter, and aortic distensibility were examined in patients with Marfan's syndrome. Aortic diameters were measured at the sinus of Valsalva, the ascending aorta, the aortic arch, and the abdominal aorta in 20 patients (aged 5-63 years) with Marfan's syndrome and 30 age-matched normal control subjects. The aortic distensibility was calculated as follows: aortic distensibility = 2 (change in aortic diameter)/(diastolic aortic diameter) (systolic pressure - diastolic pressure). Aortic diameter increased with age in both groups. The diameters of the sinus of Valsalva and the ascending aorta were greater in the Marfan group than in the control group, and increased even after adolescence in patients with Marfan's syndrome. Aortic distensibility was the highest at the abdominal aorta and the lowest at the sinus of Valsalva in both groups. Aortic distensibility decreased with age in both groups, but aortas were less distensible in the Marfan group than in the control group at all ages. The sinus of Valsalva and the ascending aorta dilate abnormally after adolescence in patients with Marfan's syndrome. However, aortic elastic properties in patients with Marfan's syndrome were abnormal even in childhood.

    In this study we used Doppler echocardiography to examine changes in ventricular diastolic function in neonates. Echocardiograms were performed in 25 healthy neonates at 1-6 days (2.7 +/- 1.6 days) and at 25-35 days (29.4 +/- 3.3 days) after birth. Ventricular inflow velocity curves were recorded using the pulsed-Doppler method. Peak velocities (peak E, A), mean velocities (mean E, A), times (time E, A), and diastolic velocity-time integrals (area E, A) were measured during both early ventricular filling and atrial systole. The acceleration time of the wave during early ventricular filling was also measured. Peak E and A and mean E and A in both ventricles increased at I month after birth. Acceleration times in both ventricles were shortened, The ratio of area E to A in both ventricles and of peak E to A in the left ventricle did not change at 1 month after birth. Only the ratio of peak E to A in the right ventricle increased. The ratio of peak E to (area E + area A), which is thought to be a load-independent index, increased in both ventricles. The authors concluded that ventricular relaxation appears to increase in both ventricles, 1 month after birth, and that changes in diastolic function occur even in neonates.
