|Drawing of the left femoral triangle - shows superior portion of the femoral vein.|
|Right femoral sheath laid open to show its three compartments|
|Gray's||subject #157 626|
It is bounded by:
- (superiorly) the inguinal ligament
- (medially) the adductor longus muscle border) (medial border)
- (laterally) the sartorius muscle (medial border)
One mnemonic to remember the boundaries is "So I May Always Love Sally"
The femoral artery and vein are enveloped within the femoral sheath.
it also contains the deep inguinal nodes.
Since the femoral triangle provides easy access to a major artery, coronary angioplasty is often performed by entering the femoral artery at the femoral triangle. In first aid, heavy bleeding in the leg can be stopped by applying pressure to points in the femoral triangle.
Several mnemonics have been created to remember the order of the nerve, artery, and vein in this triangle:
- lateral to medial - "NAVY": nerve, artery, vein, Y-fronts. (Y-fronts are a brand of underwear.)
- lateral to medial - "NAVEL" nerve, artery, vein, empty space, lymphatics.
- medial to lateral - "VAN": vein, artery, nerve. These three structures are found in the same order in the intercostal space, from top to bottom.
- medial to lateral - "vagina, artery, nerve"
- the phrase "venous near the penis" can be used to remember that the vein is more medial than the artery or nerve.
