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] Usually, a healthy vein is located and sewn above and below the blockage to bypass the narrowed or blocked femoral artery. [6]
While there are many anatomical arrangements for vascular bypass grafts in the lower extremities depending on the location of the disease, the principle is the same: to restore blood flow to an area without normal flow. [citation needed] For example, a femoral-popliteal bypass ("fem-pop") might be used if the femoral artery is occluded. A fem ...
The femoral artery gives off the deep femoral artery and descends along the anteromedial part of the thigh in the femoral triangle. It enters and passes through the adductor canal , and becomes the popliteal artery as it passes through the adductor hiatus in the adductor magnus near the junction of the middle and distal thirds of the thigh.
Finite element method (FEM) is a popular method for numerically solving differential equations arising in engineering and mathematical modeling. Typical problem areas of interest include the traditional fields of structural analysis , heat transfer , fluid flow , mass transport, and electromagnetic potential .

A valvulotome is a catheter-based controllable surgical instrument used for cutting or disabling the venous valves. [1] This is needed to enable an in situ bypass in patients with an occluded artery (especially femoral artery), where the saphenous vein is disconnected from the venous system and connected to arteries above and below the occluded segment to allow blood to flow to the lower leg.
Coronary artery bypass graft surgery has been in practice since the 1960s. Historically, vessels—such as the great saphenous vein in the leg or the radial artery in the arm—were obtained using a traditional "open" procedure that required a single, long incision from groin to ankle, or a "bridging" technique that used three or four smaller incisions.
2D FEM mesh, the triangles are the elements, the vertices are the nodes. The finite element method ( FEM ) has been the tool of choice since civil engineer Ray W. Clough in 1940 derived the stiffness matrix of a 3-node triangular finite element (and coined the name).
