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.

Articles Cases Courses Quiz. The respiratory distress is due to severe pulmonary hypoplasiapersistent pulmonary hypertension of the newborn PPHNand poor surfactant production, all of which are typical characteristics of CDH.
They contain several components of the bronchi, including respiratory epithelia, mucous glands, and cartilage and may occur anywhere along the length of the trachea or esophagus. Associated malformations and chromosomal anomalies in 42 cases of prenatally diagnosed diaphragmatic hernia.
Some of the limitations of use of bochdalej LHR for predicting outcome:.
Dysregulation of imprinted genes on 11p The precise reason why this happens is not known. Laparoscopic repair of a Bochdalek hernia in hdrnia A left Bochdalek hernia bkchdalek repaired by thoracoscopy. The most common abnormalities are trisomy 18 and isochromosome 12p Pallister-Killian syndrome or PKS hetnia, although many additional abnormalities have been reported Table 1. Although not specific for CDH, polyhydramnios is often detected [ Witters et al ].
During ECMO the pulmonary artery has a chance to rest, as it were, thus hopefully reducing the presence of pulmonary hypertension, one of the biggest complication of CDH cases.
Facial dysmorphology epicanthal folds, short nose, depressed nasal bridge, micrognathiacleft palate, short stature, short neck, vertebral anomalies, mild intellectual disability, tracheal anomalies.
Almost all individuals with CDH have some degree of pulmonary hypoplasia.
Congenital diaphragmatic hernia
Additionally, recurrent chest infections and gastrointestinal symptoms have been reported in those with previously undiagnosed Morgagni hernia.
Milder degrees of diaphragmatic eventration can present later in life with respiratory symptoms such as cough mofgagni pneumonias, or without symptoms so that the diagnosis is made incidentally mortagni chest x-ray. Diaphragmatic hernia is a multifactorial condition, which means that “many factors,” both genetic and environmental, are involved. Single-Gene Disorders Some of the more common monogenic moorgagni in which CDH occurs are listed in Table 2 ; a few of these syndromes are presented in greater detail below.
Chromosome analysis of fetal cells obtained by amniocentesis should be considered in all cases while CGH should strongly be considered when CDH is present in conjunction with additional anomalies.
Survival rates for infants with this condition vary, but have generally been increasing through advances in neonatal medicine. Find hundreds of Learning Cards covering all clinical subjects Practice answering thousands of USMLE-formatted multiple choice questions in the Qbank Explore concepts in depth with interactive images, videos and charts Fill knowledge gaps with the help of supportive features and an analysis of your progress.

ECMO performs the tasks the regularly functioning hearts and lungs do. An opening is present in the diaphragm the muscle that separates the chest cavity from the abdominal cavity.
Prenatal prognosis of congenital diaphragmatic hernia using magnetic resonance imaging measurement of fetal lung volume. For questions regarding permissions or whether a specified use is bchdalek, contact: Diaphragmatic hernias Congenital disorders of musculoskeletal system Medical mnemonics.
Bochdalek hernia – Wikipedia
The presence of a supernumerary isochromosome, consisting of two copies of the short arm of chromosome 12, confirms the diagnosis of PKS. Morgagni hernia seen on a chest radiograph. Unfortunately, the lack of large randomized controlled trials makes it difficult to determine which of these treatments may be beneficial. Both these operation is performed under general anaesthesia.
Coloboma, CVMs, choanal atresia or stenosis, genital anomalies, ear anomalies C syndrome trigonocephaly syndrome. Avoid pleurocentesis in a suspected diaphragmatic hernia because of the risk of bowel perforation, which is suggested by bile in the chest tube! A diaphragmatic hernia is the protrusion of intra-abdominal contents through an abnormal opening in the diaphragm.
Diaphragmatic eventration Diaphragmatic eventration. This rare type of CDH occurs because in the region of eventration the diaphragm is thinner, allowing the abdominal viscera to protrude upwards.
The contribution to the mature diaphragm from the septum transversum remains poorly understood. There are three different treatments available. In one US randomized trial of fetal endoscopic tracheal occlusion, the treatment group experienced a high rate of pre-term delivery and did not have improved morbidity or mortality rates [ Harrison et al ].
Non-focal neurologic abnormalities such as hypotonia are common, as are motor problems, especially in ECMO survivors [ Nijhuis-van der Sanden et al ]. Other therapies that have been introduced in the acute neonatal treatment phase for CDH but are controversial include the use of surfactant and perflubron [ Fauza et alHirschl et al ].
Multi-organ morbidity is considerable among survivors, even those with seemingly isolated CDH. Focal diaphragmatic eventration may also cause this appearance. McCredie and Reid  speculated that disturbed migration of cervical neural crest cells accounted for both problems; however, a unifying mechanism has not been proven. Eur J Pediatr Surg. Most monozygotic twin pairs described in case reports are concordant for CDH, while those listed in consecutive series generally are discordant i.
MRI is especially useful for the prenatal diagnosis of thoracic lesions that are atypical or complicated by multiple abnormalities and for assessing lung volumes. Neurodevelopmental outcomes of congenital diaphragmatic hernia survivors in a multidisciplinary clinic at ages 1 and 3. CDH can occur as an isolated finding, as part of a genetic syndrome or chromosome abnormality, or as part of a complex but nonsyndromic set of findings.
Differing degrees of bilateral pulmonary hypoplasia may explain the variance in severity seen among neonates presenting with respiratory distress and CDH. Pulmonary hypoplasia in Jarcho-Levin syndrome. Mode of Inheritance Congenital diaphragmatic hernia occurs as an isolated finding, as part of a genetic syndrome or chromosome abnormality, or as part of a complex but nonsyndromic set of findings.
Other Animal models of CDH. Both abnormalities have been reported as occurring in different members of the same family and in the same individual as cited in Ackerman et al .
Retrieved October 31, For a more detailed discussion of chromosome abnormalities and CDH, see Lurie  and Holder et al .
