Content of femoral canal

Applied/Clinical
•Access to the Femoral Artery
•The femoral artery is located (superficially or deep?) within the femoral triangle, and is thus easy to access.
This makes it suitable for a range of clinical procedures. One such procedure is coronary angiography. Here, the femoral artery is _______ with a ___ tube. This tube is navigated up the ______ artery, ______ artery, ___ , and into the coronary vessels. A radio-opaque dye is then injected into the coronary vessels, and any wall thickening or blockages can be visualised via x-ray.
Superficially
catheterised
external iliac; common iliac
aorta
Heavy bleeding in the leg can be stopped by applying pressure to points in the femoral triangle.
T/F
T
the femoral artery is positioned at the _____ point ; (medial or lateral?) to it lies the femoral vein.
Thus the femoral vein, once located, allows for femoral ______.
midinguinal
Medial
midinguinal point is the midpoint between the _______ and the ______________
pubic symphysis
anterior superior iliac spine
Femoral artery and femoral vein are highly palpable
T/F
T
both the femoral artery and vein are lacerated interior thigh wounds because they lie close together

Femoral artery and femoral vein are not used for pulse taking
T/F
F
Femoral pulse
•Just inferior to _________, it can be palpated to measure the femoral pulse.
where the femoral artery crosses the inguinal ligament
The presence of a femoral pulse means that blood is reaching the lower extremity.
T/F
