|Left lower extremity angiogram|
A catheter was placed via the left common femoral artery with the tip positioned in the left external iliac artery. Contrast is being injected through the catheter as sequential images are obtained to follow the contrast as it travels down the arteries of the leg.
To pause the movie, click once. To resume it, double click.
Observe the following:
The multiple branches originating from the profunda femoral artery, supplying the thigh musculature. Note the relative paucity of branches originating from the superficial femoral artery.
The relatively straight course of the popliteal artery, and its bifurcation into the anterior tibial artery, more lateral, and the tibioperoneal trunk, more medial.
The posterior tibial artery is dominant in this patient; larger in caliber than the anterior tibial, and contributing more blood flow to the foot.
