The femoral triangle (of Scarpa) is an anatomical region of the upper inner
One mnemonic to remember the boundaries is "So I May Always Love Sally"MedicalMnemonics|1142|5414|2776|10]
Its floor is formed (medial to lateral) by adductor longus,
pectineusand iliopsoas. [cite web |url=http://mywebpages.comcast.net/wnor/antthigh.htm |title=Anterior Thigh |accessdate=2008-01-27 |format= |work=] Its roof is formed by the fascia lata.
It is important as a number of vital structures pass through it, right under the skin. The following structures are contained within the femoral triangle (from lateral to medial):
femoral nerve(not contained within the femoral sheath)
These structures are also within the femoral triangle:
Iliopsoasmuscle ( Iliacusand Psoas majortendons joined together)
deep inguinal lymph 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 type of underwear.)
* lateral to medial - "NAVEL" nerve, artery, vein, empty space,
* 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 - "vein, artery, nerve"
* the phrase "venous near the
penis" can be used to remember that the vein is more medial than the artery or nerve.
* medial to lateral - "IVAN": Inside, Vein, Artery, Nerve
* lateral to medial "Take a SIP of the Adductor Longus, that's next to my penis": Sartorius, Ilipsoas, Pectineus, Adductor Longus
* - "Anterior and Medial Thigh Region: Boundaries of the Femoral Triangle"
