In , Morgagni described the classical anterior diaphragmatic hernia, which today bears his name—Morgagni hernia. In , Bochdalek described both. Folia Morphol (Warsz). Feb;70(1) A review of Morgagni and Bochdalek hernias in adults. Gedik E(1), Tuncer MC, Onat S, Avci A, Tacyildiz I, Bac B. Most CDHs that are recognized in utero are of the Bochdalek type, resulting from a posterior defect in the diaphragm. Morgagni hernias result from an anterior.

Infants with CDH are treated with minimal sedation and pressure support modes of ventilation; some centers use high-frequency oscillatory ventilation HFOV. The diaphragm is the structure that separates the thoracic and abdominal cavities to maintain the pressure differentials of the respective compartments.
For information on selection criteria, click here. CDH and genitourinary abnormalities. Single-Gene Disorders Some of the more common monogenic syndromes in which CDH occurs are listed in Table 2 ; a few of these syndromes are presented in greater detail below. Individual rates vary greatly dependent upon multiple factors: Once the diagnosis of CDH has been established, the following approach can be used to try to identify a specific cause of the disorder and to aid in discussions of prognosis and genetic counseling.
Bochdalfk diaphragmatic hernia associated with duplication of 11qqter. Macrosomia, nephromegaly with renal hamartomas, most often nephroblastosishydronephrosis, increased risk for Wilms tumor, hepatomegaly, hyperplasia of the endocrine pancreas, typical facial appearance, high neonatal lethality, intellectual disability in survivors Poland anomaly.
Currently, high-risk fetuses in Europe or in a few US centers may receive tracheal occlusion by fetal endoscopic balloon placement. In a Morgagni hernia, the tendon that should develop in the middle of the diaphragm does not develop properly.
Many babies will have chronic lung disease and may bochddalek oxygen or medications to help their breathing for weeks, months, or years. After the baby is stable and his or her state has improved, the diaphragm can be fixed and the misplaced organs can be relocated to their correct position.
Newborns may present with respiratory distress at birth similar to a Bochdalek hernia. The key determinants of mortality are: A genetic model for a central septum transversum congenital diaphragmatic hernia in mice lacking Slit3.
Morgagni hernia: a rare form of congenital diaphragmatic hernia.
When CDH is found on routine prenatal ultrasound examination, both a high-resolution ultrasound examination and fetal MRI to determine the presence of additional structural anomalies are indicated. Other therapies that have been introduced in the acute neonatal treatment phase for CDH but are controversial include the use of surfactant herniia perflubron [ Fauza et alHirschl et al ]. Denys-Drash syndrome is a characteristic malformation complex consisting of genital anomalies, typically undermasculinized 46, XY individuals, nephropathy diffuse mesangial sclerosisand an increased risk for Wilms tumor.
XL but males less severely affected than females.
At times, the symptoms may not become obvious till adulthood.

Studies will be needed to clarify this issue. Several distinct “subtypes” are described, but considerable overlap in the anatomic location among these defects exists. Support Center Support Center.
Children with congenital diaphragmatic hernia are at risk for lower levels of cognitive functioning and increased emotional and behavioral problems. Typical findings include hemivertebrae, vertebral fusion, scoliosis, rib anomalies, short stature, cleft palate, digital anomalies, and renal anomalies. Definition The diaphragm is the structure that separates the thoracic and abdominal cavities to maintain the pressure differentials of the respective compartments.
Kindreds representing both syndromic and nonsyndromic CDH consistent with autosomal dominantautosomal recessiveand X-linked patterns of inheritance have been reported.
Correction of hypercapnea and pre-ductal hypoxemia are focused on assuring adequate end-organ perfusion. Higher prevalence rates may be seen in studies that have fuller ascertainment including a greater number of prenatally diagnosed cases [ Skari et al ] or that examine a geographically defined population with a thorough review of all postmortem cases, including those with unexplained respiratory distress.
X-ray of chest shows intestinal shadow arrow above the diaphragm CT scn shows part of the stomach arrow in the chest. Since both pre- and postnatal advances in treatment have increased survival of high-risk patients, it is important to provide close follow-up and support for potential long-term morbidities. Prominent clinical features in children diagnosed postnatally are bitemporal sparseness of hair, facial dysmorphology brachycephaly, high broad forehead, ocular hypertelorism, low-set ears, broad nasal bridge, anteverted nostrils, and long philtrum that progressively coarsens over time, short neck with nuchal skin redundancy, short broad hands, linear streaks of skin hyperpigmentation, and normal growth.
Trigonocephaly caused by metopic craniosynostosis, orofacial anomalies deep midline palatal groove, broad alveolar ridges, multiple hernairenal anomalies, genital anomalies, cardiovascular defects, short limbs, polydactyly, loose skin, intellectual disability.
Whether bochdaek liver is up in the chest or remains down below the diaphragm [ Albanese et al ].
There are three different treatments available. Congenital diaphragmatic hernia Morgagni hernia seen on a chest radiograph.
Some, but not all, studies show that a right-sided hernia is associated with greater mortality than a left-sided hernia [ Skari et al ]. Morgagni hernia Morgagni herniation Morgagni’s hernia. A hearing test should be performed prior to discharge from the hospital. In a Bochdalek hernia, the diaphragm may not develop properly, or the intestine may become trapped in the chest cavity as the diaphragm is forming.
Although these are some factors that contribute to a Bochdalek hernia, it does not take all variables into account. Unilateral symbrachydactyly, ipsilateral aplasia of the sternal head of the pectoralis major muscle.
Learning Radiology – Morgagni, Bochdalek, Hernia, diaphragmatic
Associated malformations and chromosomal anomalies in 42 cases of prenatally diagnosed diaphragmatic hernia. Genes that control the development of migrating muscle precursor cells. Gray’s atlas of anatomy. Turn recording back on. This underdevelopment of the lungs is called pulmonary hypoplasia. Differing degrees of moorgagni pulmonary hypoplasia may explain the variance in severity seen among neonates presenting with respiratory distress and CDH.
A small left heart, sometimes called hypoplastic left heart syndrome, is sometimes “diagnosed” in individuals with left-sided CDH. With this type of birth defect, some of the organs that are normally found in the abdomen move up into the chest cavity through this abnormal opening.
Undescended testes commonly coexist with CDH; ectopic or absent testes are also reported.
