INTRODUCTIO
N
• Femoral sheath is a funnel-shaped
of fascia enclosing the upper 3 to 4
cm of the femoral vessels .
• The sheath is formed by
downward extension of two
layers of the fascia of the abdomen
.
• The anterior wall of the sheath is
formed by the fascia transversalis
which lies in the anterior abdominal
wall deep to the transversus
abdominis; and the posterior wall is
formed by the fascia iliaca , which
covers the iliacus muscle .
• Inferiorly , the sheath merges with
connective tissue around the
femoral vessels .
• The femoral sheath is
asymmetrical . Its lateral wall is
vertical , and the medial wall is
oblique being directed downward
and laterally .
COMPONENTS
• Three compartments
1
• The lateral or arterial compartment
contains the femoral artery and the
femoral branch of the
genitofemoral nerve
2
• The intermediate or venous
compartment contains the femoral
vein .
3
• The medial or lymphatic
compartment is the smallest of all ,
and is known as the femoral canal
KEYPOINTS
• Covers femoral vessels
• Lateral wall – vertical
• Medial wall – oblique
• Three compartments
• 1 – femoral artery , genitofemoral nerve
• 2 – femoral vein
• 3 – femoral canal
