Indirect inguinal hernias are associated with which congenital process?

• A. Patent processus vaginalis
• B. Patent ductus arteriosus
• C. Umbilical hernia
• D. Omphalocele

Answer: (A)

Failure of the processus vaginalis to close after testicular descent leaves a patent channel from the peritoneal cavity into the inguinal canal. An indirect inguinal hernia occurs because abdominal contents can herniate through this patent tract, passing lateral to the inferior epigastric vessels into the inguinal canal along the path of the spermatic cord. This congenital persistence of the processus vaginalis is the mechanism underlying indirect inguinal hernias. The other options describe unrelated conditions: patent ductus arteriosus is a fetal heart defect; an umbilical hernia and omphalocele involve the umbilical region, not the inguinal canal.
