Blockages caused by plaque build-up or atherosclerosis in any of these arteries can reduce leg blood circulation, causing leg pain that may interfere with daily life. [4] Standard popliteal bypass surgery involves the bypass of the popliteal artery. [5] During surgery, incisions are made depending on the location of the blockage. [3]
The popliteal artery entrapment syndrome (PAES) is an uncommon pathology that occurs when the popliteal artery is compressed by the surrounding popliteal fossa myofascial structures. [1] This results in claudication and chronic leg ischemia. This condition mainly occurs more in young athletes than in the elderlies. [2]
The bones of the popliteal fossa are the femur and the tibia. Like other flexion surfaces of large joints ( groin , armpit , cubital fossa and essentially the anterior part of the neck ), it is an area where blood vessels and nerves pass relatively superficially, and with an increased number of lymph nodes .
The popliteal fossa is to be examined bilaterally (on both sides) with the knee in a semi-flexed position. In some 60% of cases, the popliteal aneurysm presents as a palpable pulsatile mass at the level of the knee joint. Doppler ultrasonography is the preferred diagnostic method. CT angiography and MR angiography may also be employed. [2]
Outer hip pain might be caused by one of the gluteal muscles in the hip or tightness in the long band of connective tissue that runs down the leg, called the iliotibial (IT) band.
The common fibular nerve is the smaller terminal branch of the sciatic nerve. The common fibular nerve has root values of L4, L5, S1, and S2. It arises from the superior angle of the popliteal fossa and extends to the lateral angle of the popliteal fossa, along the medial border of the biceps femoris.
The deep fascia of leg or crural fascia forms a complete investment to the muscles, and is fused with the periosteum over the subcutaneous surfaces of the bones.. The deep fascia of the leg is continuous above with the fascia lata (deep fascia of the thigh), and is attached around the knee to the patella, the patellar ligament, the tuberosity and condyles of the tibia, and the head of the fibula.
If the femoral artery has to be ligated surgically to treat a popliteal aneurysm, blood can still reach the popliteal artery distal to the ligation via the genicular anastomosis. However, if flow in the femoral artery of a normal leg is suddenly disrupted, blood flow distally is rarely sufficient.
