Prenatal ultrasound diagnosis of Cantrell's syndrome and image analysis / 中华医学超声杂志（电子版）

ABSTRACT

ObjectiveTo summarize prenatal ultrasound image features of Cantrell′s syndrome (Cantrell′s pentalogy).MethodsFrom January 2007 to December 2013 in Shenzhen Maternity & Child Healthcare Hospital, there were twenty cases diagnosed and conifrmed by postmortem as Cantrell′s syndrome. The prenatal ultrasound image features and outcomes were analyzed.ResultsAmong the twenty cases, eighteen were singleton and two were twins with the other normal fetus. Prenatal ultrasound image two obvious ultrasound image features of ectopic heart and hight omphalocele (seventeen cases) or gastroschisis (three cases) were appeared in prenatal ultrasound of twenty cases. Fourteen cases were complete ectopic heart (Ectopic heart was located within the omphalocele in one case, ectopic heart was completely exposed in amniotic lfuid in thirteen cases), six cases were incomplete ectopic heart, three cases were ventricular septal defect in which one was associated with pulmonary stenosis, two cases were single atrium and single ventricle in which one was associated with a single arterial trunk, one case was tetralogy of Fallot, and six cases were without signiifcant heart abnormalities. Associated with other abnormalities seventeen cases were associated with other abnormalities in twenty cases, in which eleven cases were spinal abnormalities, nine cases were umbilical cord abnormalities (short umbilical cord in six cases, single umbilical artery in two cases, short umbilical cord associated with single umbilical artery in one case), ifve cases were neurological abnormalities (exencephalia in four cases, encephalocele in one case), four cases were limb abnormalities, three cases were cheilopalatognathus, one case was giant bladder. Three cases weren′t associated with other abnormalities. Nuchal Translucency in eight cases, nuchal translucency were measured in early pregnancy. Nuchal translucency of ifve cases were thick, one case was cervical hygroma in one of the two twins. Chromosome examination results: only three cases had chromosome examination in twenty cases, in which one case was trisomy 21, another two were chromosome normal. Fetal outcome and examination results: in twenty cases, one of the two twins can′t survive after birth, and the other one of two twins was reduced in intrauterine, so the specimen could not be obtained. Eighteen cases of singleton underwent labor induction. The results of postmortem appearance (nineteen cases) and autopsies (ifve cases) were all consistent with prenatal ultrasound scan.ConclusionsEctopic heart and hight omphalocele or gastroschisis appearing at the same time was the characteristic of Cantrell′s syndrome in prenatal ultrasound and other abnormalities may be part of the Cantrell′s syndrome spectrum. It is beneift to detect and diagnose Cantrell′s syndrome by prenatal ultrasound in the ifrst trimester.
