Pain from such nerve compression is usually referred, in this case to the skin overlying the medial aspect of the calf, ankle or foot. Because the artery is closely applied to the popliteal surface of the femur and the joint capsule , fractures of the distal femur or dislocations of the knee may rupture the artery, resulting in hemorrhage.
Patients with PAES mainly present with intermittent feet and calf pain associated with exercises and relieved with rest. [3] PAES can be diagnosed with a combination of medical history, physical examination, and advanced imaging modalities such as duplex ultrasound , computer tomography , or magnetic resonance angiography .
A Baker's cyst, also known as a popliteal cyst, is a type of fluid collection behind the knee. [4] Often there are no symptoms. [2] If symptoms do occur these may include swelling and pain behind the knee, or knee stiffness. [1] If the cyst breaks open, pain may significantly increase with swelling of the calf. [1]
The tributaries of the popliteal vein include: Veins that correspond to branches given off by the popliteal artery (see popliteal artery).; the small saphenous vein, which perforates the deep fascia and passes between the two heads of the gastrocnemius muscle to end in the popliteal vein.
The flow of lymph from the legs towards the heart is the result of the calf pump– during walking the calf muscle contracts, squeezing lymph out of the leg via the lymphatic vessels. When the muscle relaxes, valves in the vessels shut preventing the fluid from returning to the lower extremities. [3]
The surgery is generally performed under general anaesthesia. The surgeon makes an incision in the upper leg, and a graft either man-made or the patient's vein is sewn to both ends of the artery. [20] The graft reroutes the blood flow around the blocked artery, allowing for adequate supply back to the parts of the leg.
Moving from superficial to deep structures, the roof is formed by: the skin. [1]the superficial fascia. [1] This contains the small saphenous vein, the terminal branch of the posterior cutaneous nerve of the thigh, posterior division of the medial cutaneous nerve, lateral sural cutaneous nerve, and medial sural cutaneous nerve.
Sciatica is pain going down the leg from the lower back. [1] This pain may go down the back, outside, or front of the leg. [3] Onset is often sudden following activities such as heavy lifting, though gradual onset may also occur. [5] The pain is often described as shooting. [1] Typically, symptoms are only on one side of the body. [3]
