Iliac artery pulsation weakens or disappears

The iliac artery is deep, adjacent to the femoral condyle and posterior to the knee capsule. Slanted outward along the outer edge of the semitendinosus muscle to the femoral condylar fossa level at the middle of the posterior knee, and then vertically down to the lower edge of the diaphragm, divided into anterior tibial artery and posterior tibial artery. The former enters the anterior calf area through the upper edge of the interstitial membrane, and the latter passes the deep side of the soleus tendon arch to the posterior area of ​​the calf. In addition to the muscular branches distributed in the adjacent muscles, the artery has five joint branches, namely, the superior medial and lateral arteries of the knee, the medial knee, and the medial and lateral arteries of the knee, all participating in the formation of the knee arterial network. The upper iliac artery is closely related to the femoral condyle.
