Ultrasound showing an indirect inguinal hernia [18] Incarcerated inguinal hernia [19] An indirect inguinal hernia results from the failure of embryonic closure of the deep inguinal ring. In the male it can occur after the testicle has passed through the deep inguinal ring. It is the most common cause of groin hernia. A double indirect inguinal ...
Although women account for roughly 70% of femoral hernia repairs, indirect inguinal hernias are still the most common subtype of groin hernia in both males and females. [14] Inguinal hernia surgery is also one of the most common surgical procedures, with an estimated incidence of 0.8-2% and increasing up to 20% in preterm children. [15] [16]
An indirect inguinal hernia and a direct inguinal hernia can be distinguished by their positioning in relation to the inferior epigastric vessels. An indirect hernia is situated laterally to these vessels, whereas a direct hernia is positioned medially to them. Inguinal hernias are the most common type of hernia in both men and women.
A hernia that exits the abdominal cavity directly through the deep layers of the abdominal wall, thereby bypassing the inguinal canal, is known as a direct inguinal hernia. In males with strong presentation of the cremasteric reflex , the testes can—during supine sexual activity or manual manipulation—partially or fully retract into the ...
Sometimes a direct hernia may be present with an indirect hernia on the same side when it is known as a saddlebag hernia. Like other flexion surfaces of large joints ( popliteal fossa , armpit , cubital fossa and essentially the anterior part of the neck ), it is an area where blood vessels and nerves pass relatively superficially, and with an ...
In human anatomy, the inferior epigastric artery is an artery that arises from the external iliac artery. [1]: 225 It is accompanied by the inferior epigastric vein; inferiorly, these two inferior epigastric vessels together travel within the lateral umbilical fold (which represents the lateral border of Hesselbach's triangle, the area through which direct inguinal hernias protrude. [2])
A direct inguinal hernia will protrude through Hesselbach's triangle, whose borders are the rectus abdominis (medially), inferior epigastric artery and inferior epigastric vein (superolaterally), and the inguinal ligament (inferiorly). The hernia lies medial to the inferior epigastric artery. [3] This is in contrast to an indirect inguinal ...
There is the potential for an indirect inguinal hernia to develop, although not all people with a patent vaginal process will develop one. The more patent the vaginal process, the more likely the patient is to develop a hernia.
