| Case | MA | GAD | Abnormal sonographic findings | Autopsy findings |
|
| 1 | 22 | 22 weeks | Deficient skull vault above the orbits anteriorly and occiput posteriorly. Brain parenchyma covered by membrane. Short right forearm with single bone and hand bones could not be made out (Figures 1 and 2). | Extensive irrational asymmetric deformation and disruption. Amputated calvarium, proptosis, right upper limb with short humerus, and short forearm, right elbow joint fused (ulnar club hand), amputation of multiple digits of both hands, syndactyly of first four toes of left foot, and amnion bands confirmed the diagnosis of amniotic band syndrome |
|
| 2 | 24 | 32 | Absent right lower limb and short left femur with constrictive ring at lower thigh. Normal left leg bones (live female baby). | |
|
| 3 | 22 | 23-24 | Anterior abdominal wall defect with herniation of bowel loops and liver. Persistent extra embryonic coelomic cavity. Short spine with kyphoscoliotic deformity. Bilateral short legs with club foot. Evidence of amniotic bands was noted (Figures 3(a) and 3(b)). | Parents not accepted |
|
| 4 | 20 | 15-16 | Abdominal wall defect with herniation of liver and bowel loops. Lower fetus was placed in the coelomic cavity. Abnormally positioned lower limbs, kyphoscoliotic deformity of spine, and multiloculated cystic area were noted at neck region (Figure 4). | Not done |
|
| 5 | 24 | 11 ± 1 WK | Large thoracoabdominal wall defect with evisceration of abdominal contents and heart were noted within the extraembryonic coelomic cavity. Herniated organs are connected to the placenta by a short cord. E/o occipital encephalocele with kyphoscoliotic deformity. NT could not be made out. | Not done |
|
| 6 | 21 | 11-12 | Absent calvarium with floating brain parenchyma. Nuchal edema, herniation of heart, liver, bowel loops, and bladder. The eventrated organs are located in the extraembryonic coelomic cavity. Thin amniotic bands and spinal dysraphism were noted (Figure 5). | Not done |
|
| 7 | 24 | 12-13 | Increased NT and omphalocele major (herniated liver & urinary bladder) were noted within the coelomic cavity. Short umbilical cord and suspicious unilateral club foot were noted (Figure 6). | Not done |
|
| 8 | 22 | 12-13 | Increased NT and thoracoabdominoschisis with eviscerated heart, liver, and urinary bladder noted within the coelomic cavity. Abnormally positioned lower limbs, kyphoscoliotic deformity, and short umbilical cord (Figure 7). | Not done |
|
| 9 | 26 | 11 ± 1 | Increased NT and large median ventral wall defect with eventrated organs (heart & liver) which are adherent to placenta cord could not be made out. | Not done |
|
| 10 | 24 | Fetus A-11-12,
fetus B-12-13 | Dichorionic diamniotic live twin pregnancy with fetus B: normal. Fetus A shows herniation of heart, liver, and bladder in the coelomic cavity. Abnormally placed lower limbs and kyphoscoliotic deformity. NT was raised (Figure 8). | |
