Medical diagnosis of pulmonary hypoplasia in utero may use imaging, usually ultrasound or MRI. [12] [13] The extent of hypoplasia is a very important prognostic factor. [14]One study of 147 fetuses (49 normal, 98 with abnormalities) found that a simple measurement, the ratio of chest length to trunk length, was a useful predictor of postnatal respiratory distress. [15]
Pulmonary agenesis is an inborn lung underdevelopment that is rare and potentially lethal. [1] The disorder is caused by a complete developmental arrest of the primitive lung during embryonic life, and it is often associated with other developmental defects. [2]
Bronchopulmonary dysplasia (BPD; part of the spectrum of chronic lung disease of infancy) is a chronic lung disease which affects premature infants. Premature (preterm) infants who require treatment with supplemental oxygen or require long-term oxygen are at a higher risk. [ 1 ]
A semi-quantitative lung ultrasound score performed during bedside lung echography was first described by Brat et al. and found to correlate with the oxygenation status of infants with RDS. [23] Since then, several studies have supported the use of lung ultrasound scores to earlier predict an initial dose of surfactant when compared to current ...
After delivery, if the patient is symptomatic, resection is mandated. If the infant is asymptomatic, the need for resection is a subject of debate, though it is usually recommended. Development of recurrent infections, rhabdomyosarcoma, adenocarcinomas in situ within the lung malformation have been reported. [4]
Alveolar capillary dysplasia (ACD) is a rare, congenital diffuse lung disease characterized by abnormal blood vessels in the lungs that cause highly elevated pulmonary blood pressure and an inability to effectively oxygenate and remove carbon dioxide from the blood.
Congenital diaphragmatic hernia (CDH) is a birth defect of the diaphragm. The most common type of CDH is a Bochdalek hernia; other types include Morgagni hernia, diaphragm eventration and central tendon defects of the diaphragm. Malformation of the diaphragm allows the abdominal organs to push into the chest cavity, hindering proper lung formation.
Infant respiratory distress syndrome, in turn, is the leading cause of death in preterm infants, affecting about 1% of newborn infants. [8] Birth defects cause about 21 percent of neonatal death. [7] Some major causes of perinatal mortality rate is: Maternal diseases; Pelvic diseases; endometriosis, ovarian tumor
