Femoral hernia intestinal obstruction. A strangulated femoral hernia occurs when a constriction of the hernia limits or completely obstructs blood supply to part of the bowel involved in the hernia. Strangulation can occur in all hernias, but is more common in femoral and inguinal hernias due to their narrow "weaknesses" in the abdominal wall. Nausea, vomiting, and severe abdominal pain are characteristics of a strangulated hernia. This is a medical emergency as the loss of blood supply to the bowel can result in necrosis (tissue death) followed by gangrene (tissue decay). This is a life-threatening condition requiring immediate surgery. The term incarcerated
Inguinal lymph nodes Inguinal lymph nodes Inguinal lymph nodes are the lymph nodes in the inguinal region (groin). They are located in the femoral triangle, and are grouped into superficial lymph nodes, and deep lymph nodes. The superficial lymph nodes have three divisions – the superomedial, superolateral, and inferior superficial lymph nodes. They are divided into three groups: There are approximately ten superficial lymph nodes, and they drain to the deep inguinal lymph nodes. Inguinal lymph nodes may normally be up to 2 cm in size. They receive lymphatic afferents from the following: There can be three, four or five deep inguinal lymph
