Congenital anomalies may be inherited or sporadic, isolated or multiple, apparent or hidden, gross or microscopic.
A major anomaly is apparent at birth in 3 to 4% of newborns; up to 7.5% of children manifest a congenital defect by age 5 yr.
Incidence varies with the type of defect; the geographic area, presumably due to genetic and/or environmental factors (spina bifida occurs in 3 to 4/1000 births in areas of Ireland but in 1/1000 in the USA); and cultural practices (consanguineous marriages increase the risk of genetic abnormalities).

Congenital lung malformations are a family of structural developmental abnormalities of the lung that arise from an error in the embryologic development of the lung.
It is usually located in, and limited to, one of the lower lobes.  A large abnormal blood vessel, typically arising from the aorta (the main artery bringing blood from the heart to the body), enters the sequestration.
Whether or not surgery is indicated for all lung malformations is controversial, and the answer is not known.

 What is the Chiari Malformation?
The Chiari I Malformation is considered a congenital malformation, although there have been some reported cases of an acquired form.
It is characterized by a small or misshapen posterior fossa (the compartment in the back of the skull), a reduction in cerebrospinal fluid pathways and a protrusion of the cerebellar tonsils through the bottom of the skull (foramen magnum) into the spinal canal.
It is recommended that patients diagnosed with a Chiari Malformation have the entire spine imaged to rule out the presence of a syrinx, since it may be a consideration in treatment and prognosis.

Other vascular malformations can develop from any type of blood vessel and develop in any part of the body, although the majority involves the extremities.
This type usually does not affect the venous circulation which returns blood to the heart, but these masses of venous malformation can be unsightly, cumbersome, or be the site of blood clots (which fortunately, are not the kind that travel to the heart or lungs).
Arterial defects or malformations are the least common type of CVM, being responsible for only 1-2 percent of the total.

 Congenital definition - Medical Dictionary definitions of popular medical terms
A condition that is congenital is one that is present at birth.
Versus "genetic": One dictionary erroneously defines "congenital" as meaning: "Occurring prior to birth, due to parent's genetic input." Congenital does not mean genetic.
Timing: Something that is congenital may or may not occur "prior to birth." The essential feature is that it is there at birth (if not before).

 News - Congenital Malformation Risk Tripled By Epilepsy Therapy During Pregnancy
Women who take antiepileptic drugs during pregnancy have triple the risk of congenital malformation or developmental delay in their offspring.
When children from families with a history of developmental delay were excluded, the researchers found that 19 percent of exposed children, and only 3 percent of non-exposed siblings, had such problems.
Overall, 31 percent of exposed children had either major malformations or developmental delay; 52 percent had facial dysmorphism, compared with 25 percent of children not exposed; 31 percent had childhood medical problems, compared with 13 percent among non-exposed siblings; and 20 percent had behavior disorders, compared with 5 percent among non-exposed siblings.

 Medical Genetics and Congenital Malformation   (Site not responding. Last check: 2007-10-01)
A physician should be able to distinguish between genetic and non-genetic congenital disorders, as well as recognize genetic diseases presenting later in childhood.
A genetic disorder, a condition caused by abnormal genes or chromosomes, should be contrasted with a congenital malformation, one which is apparent at birth and not known to be related to any specific genetic abnormality.
Genetic abnormalities may produce congenital malformations, metabolic disturbances, specific organ dysfunction and abnormalities of sexual differentiation.
