I think there is a difference between putting clips across the trachea and having a complete tracheal occlusion versus having a balloon tracheal occlusion in terms of the rate of increase of the LHR, the ultimate size of the lung.
quote · Fetal Surgery
Ep 10 · 16:10
watchful waiting can be very hazardous if you wait for the mother to go into preterm labor or the fetus to evolve significant high output failure and just allow nature to take its course, and the majority of those kids will die

I think the future in fetal surgery are clinical trials, reduction of maternal and fetal risk, and that may make open fetal surgery obsolete in many of these anomalies

clinical Essential components of EXIT procedure include maintenance of uteroplacental blood flow, complete uterine relaxation, maintenance of intrauterine volume, maternal homeostasis and hemostasis, control of membranes, and avoiding placenta and cord
Ep 10 · 19:10
clinical EXIT procedure requires a multidisciplinary team with specific roles for each member
Ep 10 · 19:42
quote It's not a minor undertaking and requires a lot of coordination between services to do an optimal exit procedure
Ep 10 · 20:42
quote there was no way that child would have survived
Ep 10 · 21:05
clinical CHAOS (congenital high airway obstruction syndrome) can result in marked diaphragm inversion, ascites, and thoracic abnormalities
Ep 10 · 21:33
clinical CHAOS patients have to grow into their ventilatory mechanics and can have significant morbidity when treated at birth
Ep 10 · 23:57
quote I think the future in fetal surgery are clinical trials, reduction of maternal and fetal risk, and that may make open fetal surgery obsolete in many of these anomalies
Ep 10 · 26:38
clinical CVR is calculated by measuring CPAM in 3 dimensions, applying ellipse formula, and dividing by head circumference to standardize for gestational age
Ep 10 · 27:05
clinical CVR has been reliable for predicting hydrops risk, determining surveillance frequency, and counseling families
Ep 10 · 27:48
clinical Failure of steroid therapy is defined as progression of hydrops
Ep 10 · 28:05
clinical Patients on steroids for CPAM should be monitored with ultrasound every other day or 2-3 times per week because changes can occur rapidly
Ep 10 · 29:11
clinical Steroids have had a dramatic impact on reducing the number of open fetal surgeries for microcystic CPAM
Ep 10 · 29:23
clinical Macrocystic CPAMs and bronchial atresia do not respond as well to steroids as microcystic CPAMs
