ABSTRACT Most cases of isolated nonduodenal bowel atresia are thought to be due to ischemic events from hypotension, vascular accident, volvulus, intussusception and cocaine. We present a case of isolated ileal atresia suggested using results of prenatal sonography which showed multiple markedly dilated fluid-filled intestinal loops with changeable shapes and positions secondary to active peristalsis. Postnatal oral contrast radiography demonstrated obstruction located at the ileal level. Exploratory laparotomy confirmed isolated ileal atresia. Primary end-to-end anastomosis was done. The infant endured the procedure well. Cases with multiple intestinal atresia always have fatal prognosis, even after surgery. Cases of isolated intestinal atresia usually have better prognosis and deserve more attention. Early diagnosis and early intervention are both important for good outcomes.

    ABSTRACT: The purpose of this study was to determine the antenatal sonographic features of ileal atresia. We identified neonates with surgically-confirmed ileal atresia who had antenatal sonography performed in our institution between 1 January 1999 and 30 June 2009. The antenatal sonography images and reports were reviewed. Sixteen neonates had surgically-confirmed ileal atresia in our institution in 11 years. Seven fetuses (43.7%) did not have any intestinal abnormalities detected antenatally on ultrasonography. Nine fetuses (56.3%) had various sonographic features of ileal atresia, including multiple dilated bowel loops, ascites, cysts, and polyhydramnios with or without associated anomalies. Six of nine fetuses had multiple dilated bowel loops and two fetuses had ascites. One fetus had a large, cystic, mixed, echogenic dilatation of bowel. Polyhydramnios was present in three fetuses. Heart anomalies, kidney anomalies, or hydrops were present in four fetuses. Eight of 16 fetuses (50%) had other intestinal problems, including intussusceptions in one fetus, small bowel malrotation, meconium pseudocyst volvulus, meconium peritonitis, and a congenital band.   The prenatal sonographic features of ileal atresia are not simple. Various sonographic findings are shown and ileal atresia was detected in about 60% of cases.

    ABSTRACT: A 36-year-old multigravida, G2P1, underwent routine ultrasound scan at 22+1 weeks of gestation, which revealed a single normally growing fetus with left intrathoracic mass and left displacement of the cardiac apex. The left intrathoracic wedge-shaped hyperechogenic mass, measuring 32 x 25 mm in size, was situated at the lower portion of the left lung. A combination of color and power Doppler ultrasound allowed visualization of a vessel arising from the descending aorta, which supplied the mass. The diagnosis of extralobar pulmonary sequestration was made. Magnetic resonance imaging (MRI) was also performed and revealed a well-defined mass with homogeneous high-signal intensity when compared with normal lung tissue in the left upper lung field, which was compatible with pulmonary sequestration. The pulmonary mass was followed up by color and power Doppler every 2 weeks. The peak velocity of 11.85 cm/sec and the diameter of the feeding artery of 1.19 mm gradually decreased and disappeared 8 weeks later. The intrathoracic mass disappeared 10 weeks later at 32+1 gestational weeks. Repeat MRI also revealed spontaneous regression of the mass in favor of resorption of sequestration. The fetus was delivered at 38+1 gestational weeks. A male newborn weighing 2,520 g was spontaneously delivered with an Apgar score of 8 at 1 minute and 9 at 5 minutes. In our patient, it is suggested that progressive decreases in the peak velocity of the feeding vessel heralded the spontaneous regression of pulmonary sequestration not associated with hydrops/hydrothorax.
