Causes
Most likely, Bochdalek hernias are formed throughout the growth process and organ construction during fetal development. During fetal development, the diaphragm is formed between the seventh and tenth week. Also, during this time, the esophagus, stomach, and intestines are formed. Therefore, a Bochdalek hernia forms either from malformation of the diaphragm, or the intestines become locked into the chest cavity during the construction of the diaphragm. Although these are some factors that contribute to a Bochdalek hernia, it does not take all variables into account. Bochdalek hernias, along with Morgagni hernias, are both multifactor conditions, meaning that there are many reasons and multiple variables that contribute to the malformations. For example, in each case there could be genetic and or environmental condition(s) that can add to the probability of this birth defect.
