“…This is in agreement with the literature mentioning the difficulty in ultrasound prenatal diagnosis of the amniotic band and the frequent need of simultaneous presence of different congenital deformities to suggest the presence of ABS [16,17]. The use of most recent ultrasound technology (three- and four-dimensional ultrasonography) and the use of magnetic resonance imaging in some cases may improve the diagnosis [9,11,12]. …”

Objective: To describe the spectrum of clinical deformities related to amniotic band sequence (ABS), ranging from mild to severe. Methods: Retrospective evaluation of 9 cases of ABS managed during a 4-year period (February 2006 to April 2010) in a tertiary hospital. Results: The median gestational age at prenatal diagnosis was 15 weeks (range 11-26). Only 2 patients had clinical prenatal evidence of amnion rupture. In the other 5 cases the diagnosis of ABS was established prenatally based on fetal structural abnormalities. These abnormalities included: (1) upper limb defects: syndactyly, amputation at the level of phalanges or first metacarpal or forearm; (2) inferior extremities defects: tallus equinovarus and flexed knee, and constriction ring; (3) umbilical cord strangulation, and (4) acrania. Conclusion: ABS is a polymorphous syndrome and recognizing its various manifestations can be of help in prenatal identification.

“…These findings may be confirmed by fetal MRI, which is often ordered as a complimentary measure upon consideration of fetal surgery [13, 19, 20]. Amniotic bands are now being successfully released fetoscopically through minimally invasive surgery [19]. The intrauterine procedure is delicate and the decision to perform this surgery must be carefully weighed against the potential risks to the mother and the fetus versus continuing or terminating pregnancy [21–24].…”

Introduction. Amniotic band syndrome and sequence are a relatively rare condition in which congenital anomalies occur as a result of the adherence and entrapment of fetal parts with coarse fibrous bands of the amniotic membrane. A large percentage of reported cases have an atypical gestational history. The frequency of this obstetric complication is not affected by fetal gender, genetic abnormality, or prenatal infection. Case. A 21-year-old, G1P0 female parturient at 18 weeks and 5 days with a single intrauterine gestation during a routine ultrasound evaluation was noted to have amniotic band sequence. The pregnancy was subsequently complicated by preterm premature rupture of membranes with oligohydramnios, resulting in a surviving neonate scheduled for rehabilitative treatment. Conclusion. Amniotic band syndrome is an uncommon congenital anomaly resulting in multiple disfiguring and disabling manifestations. Several theories are proposed with most involving early rupture of the amnion and entanglement of fetal parts by amniotic bands. This syndrome can be manifested by development of multiple malformations, with the majority of the defects being limb abnormalities of a disorganized nature, as in the case we present. In the absence of a clear etiology of consequential congenital abnormalities, obstetric management guidelines should use shared decision models to focus on the quality of life for the offspring.

“…Ultimately, fetal imaging is the realization of immediate ultra-high resolution imaging in all aspects [58]. The procession of US and fMRI technologies seems most promising and the most modern is the high Tesla fMRI technologies, which achieves 25-µm resolution and provides internal and external anatomy [64]. Additionally, it has been suggested that Near-Infrared Spectroscopy (NIRS) can be used in the monitoring of fetal health during the EXIT procedure considering the advantageous ability of measuring hemoglobin oxygen saturation and umbilical venous oxygenation [44].…”

The anesthesia ex utero intrapartum treatment (EXIT) procedure is a specialized surgical procedure used to deliver babies who have airway compression due to cystic adenomatoid malformation, bronchopulmonary sequestration, cervical teratomas, or other congenital conditions. EXIT is erroneously known as a routine cesarean section (CS), but is rather an extension of CS with discernible differences. The procedure creates an opening in the anesthetized abdomen of the mother and uterus. Once EXIT is complete, the remainder of the CS proceeds. EXIT is much more complex than a routine CS, as it requires coordination between the mother and a multidisciplinary team of surgical and neonatal personnel. This review highlights current anesthetic concepts during the EXIT procedure.
