After an angiogram, a sudden shock can cause a little pain at the surgery area, but heart attacks and strokes usually do not occur, as they may in bypass surgery. The risk of complications from angiography can be reduced with a prior CT scan by providing clinicians with more information about number and positioning of the clots in advance.
Many procedures can be performed on the heart by catheterization. [2] This most commonly involves the insertion of a sheath into the femoral artery (but, in practice, any large peripheral artery or vein) and cannulating the heart under X-ray visualization (most commonly fluoroscopy).
Performing a cerebral angiogram by gaining access through the femoral artery or radial artery is feasible in order to treat cerebral aneurysms with a number of devices [12] Certain conditions such as contrast allergy, renal insufficiency, and coagulation disorders are contraindicated in this procedure.

On inspection the clinician looks for signs of: trauma; previous surgery ()muscle wasting/muscle asymmetry; edema (swelling) erythema (redness); ulcers – arterial ulcers tend to be on the borders / sides of the foot, neuropathic ulcers on the plantar surface of the foot, venous ulcers tend on be on the medial aspect of the leg superior to the medial malleolus.
The deep femoral artery is a large and important branch that arises from the lateral side of the femoral artery about 1.5 in. (4 cm) below the inguinal ligament. It passes medially behind the femoral vessels and enters the medial fascial compartment of the thigh .
Intravenous digital subtraction angiography (IV-DSA) is a form of angiography which was first developed in the late 1970s.. IV-DSA is a computer technique that compares an X-ray image of a region of the body before and after radiopaque iodine based dye has been injected intravenously into the body.
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]
A system of coaxial catheters is pushed inside the arterial circulation, usually through a percutaneous access to the right femoral artery. A microcatheter is finally positioned beyond the occluded segment and a stent-retriever is deployed to catch the thrombus; finally, the stent is pulled out from the artery, usually under continuous ...
