Femoral Triangle Flashcards
Floor of the femoral triangle contains what?
Pectineus and iliopsoas muscle
Roof of the femoral triangle contains what?
Fascia lata
Contents of the femoral triangle
Femoral nerve, femoral artery, femoral vein, empty space with deep inguinal lymph nodes (femoral canal)
mnemonic = NAVEL (going towards the navel)
Boundaries of the femoral triangle
Lateral border = Sartorius
Medial border = adductor longus
Base = inguinal ligament
Femoral sheath
Funnel shaped continuation of transversalis fascia
The femoral sheath encloses what part of the femoral vessel and canal?
The proximal part
Femoral sheath ends how far distally to the inguinal ligament?
4-10 cm
Femoral ring
The space that allows the femoral vein to distend in situations of hypertension and increased venous return. q
What 2 things may you find in the femoral ring?
- ) Deep inguinal lymph nodes
2. ) Potential opening for a hernia
Femoral hernia
protrusion of abdominal viscera (often a loop of small intes- tine) through the femoral ring into the femoral canal.
Why do most inguinal hernias occur in males?
inguinal hernias (approximately 86%) occur in males because of the passage of the spermatic cord through the inguinal canal
What percentage of hernias are indirect hernias?
2/3
Do males have more inguinal or femoral hernias?
inguinal
Do females have more inguinal or femoral hernias?
(f)emoral
Indirect inguinal hernia
protrusion through the inguinal ring and result of the failure of embryonic closure of the processes vaginalis after the testicle passes through it. This is congenital
Direct inguinal hernia
enters through a weak point in the fascia of the abdominal wall (hesselbach triangle)
Inguinal lymph nodes drain from where?
lower limb (gluteal region), perineum & anal canal, anterior abdominal wall up to umbillicus
