Placental vascular compromise in jejunoileal atresia

In-utero vascular accidents in neonates from COVID-19 infected mothers

PURPOSE

Infection with COVID-19 during pregnancy has been associated with a hypercoagulable state. It is unknown if maternal COVID-19 infection results in congenital anomalies secondary to intrauterine vascular accidents. This study sought to determine if the rate of in-utero vascular complications (intestinal atresia and limb abnormalities) that may be attributable to the hypercoagulable states associated with COVID-19 and pregnancy increased after the onset of the pandemic.

METHODS

Pregnancy, neonatal, and congenital defect data from a single academic medical center and the partner's children's hospital were collected and compared to the period prior to onset of the pandemic. A subanalysis including pregnant woman 18 years or greater with documented COVID-19 infection during gestation between March 2020-2021 was performed.

RESULTS

Rates of intestinal atresia did not differ prior to or after the onset of the pandemic (3.78% vs 7.23%, p = 0.21) nor did rates of limb deficiency disorders (4.41% vs 9.65%, p = 0.09). On subanalysis, there were 194 women with COVID-19 infection included in analysis: 135 (69.6%) were positive during delivery admission and 59 (30.4%) were positive earlier in their pregnancy. There was one infant born with intestinal atresia.

CONCLUSION

We report a low incidence of congenital anomalies in infants born to mothers with COVID-19 infection. It remains unclear if the impact of COVID-19 on the coagulative state augments the normal pro-thrombotic state of pregnancy; ongoing surveillance is warranted.

Mesenteric Cyst in Association with Type-II Jejunoileal Atresia

A rare case of type-II jejunoileal atresia with mesenteric cyst in a neonate is being reported here with a brief review of literature.

Type IV intestinal atresia, congenital bilateral perisylvian syndrome, and chronic pulmonary hypertension secondary to multiple vascular disruption syndrome in a monochorionic twin

We describe a rare case of multiple intestinal atresias, congenital bilateral perisylvian polymicrogyria, and chronic pulmonary hypertension in a surviving monochorionic twin with co-twin demise. This constellation of congenital anomalies represents a multiple vascular disruption syndrome due to intrauterine vascular compromise in the setting of possible twin-to-twin transfusion syndrome.

Multiple intestinal atresia and congenital bilateral perisylvian syndrome in a surviving monochorionic twin with intrauterine death of the co-twin

This report presents a case of a surviving monochorionic twin with multiple intestinal atresia and congenital bilateral perisylvian syndrome, which developed after the intrauterine death of the cotwin. The pathology of the placenta demonstrated vein-to-vein communication between the twins and multiple intravascular thrombi in the dead cotwin.

Jejunal atresia presenting with mesenteric cyst in a neonate: a case report

Jejunoileal atresia is a congenital anomaly that is characterized clinically by bilious vomiting and abdominal distension. It has been associated with various congenital anomalies but its association with mesenteric cyst has only been reported sporadically. As this is a very rare entity, it is being reported with a brief review of literature.

The etiologic role of intrauterine volvulus and intussusception in jejunoileal atresia

PURPOSE

Although intussusception has been reported as quite a rare cause of jejunoileal atresia (JIA), pediatric surgeons have noted the frequent presence of intussusception as well as volvulus at surgery. The aim of this study was to investigate the contribution of intrauterine intussusception and volvulus to the development of JIA.

METHODS

In 48 newborns (24 boys and 24 girls) treated for JIA at our hospital between 1978 and 2004, the operative and pathologic findings were reviewed.

RESULTS

Intussusception was responsible for gap and cord type atresia in 12 cases (25%). The cord showed an atrophic intestinal lumen in 2 cases. Volvulus was observed in 13 cases. Volvulus and intussusception were simultaneously noted in 1 case. This suggested that intussusception was the cause of the atresia, whereas volvulus was a secondary event. Neither intussusception nor volvulus was observed in high jejunal, apple peel, or multiple atresia.

CONCLUSIONS

Intrauterine volvulus and intussusception were commonly observed in single mid- and low JIA. Thus, intrauterine intussusception may be a common cause of gap and cord type JIA. Volvulus may not only cause JIA but also result from anatomic changes after the development of JIA in some cases.
