Femoral sheath

Femoral Sheath

The Femoral Sheath is an anatomical structure in the human body, specifically located in the upper thigh. It is a funnel-shaped, fibrous extension of the abdominal fascia, which encloses the femoral artery, femoral vein, and femoral canal.

Etymology

The term "Femoral" is derived from the Latin word "femur", which means thigh. The term "Sheath" is derived from the Old English word "sceath", which means a protective covering.

Anatomy

The Femoral Sheath is approximately 3-4 cm long and is divided into three compartments. The lateral compartment contains the Femoral Artery, the intermediate compartment contains the Femoral Vein, and the medial compartment, also known as the Femoral Canal, allows for the expansion of the femoral vein.

Clinical Significance

The femoral sheath is clinically significant as it is often used as a route for catheterization in medical procedures. It is also the site of Femoral Hernia, a type of hernia that occurs when a part of the intestine pushes through the femoral canal.
