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]
Acute graft occlusion is the occlusion (blockage) of a vascular bypass graft shortly after the bypass is performed. Its causes, which are distinct from those of chronic graft occlusion , include technical failure (e.g. anastomotic stricture, incomplete valve lysis in non-reversed vein) and thrombosis.
REBOA is performed by gaining access to the common femoral artery and inserting a small endovascular catheter with an inflatable balloon within the aorta. [1] Upon inflation of the occluding balloon, blood flow across the descending aorta is either partially or completely obstructed which subsequently stanches downstream bleeding.
Thromboangiitis obliterans, also known as Buerger disease (English / ˈ b ɜːr ɡ ər /; German: [ˈbʏʁɡɐ]) or Winiwarter-Buerger disease, is a recurring progressive inflammation and thrombosis (clotting) of small and medium arteries and veins of the hands and feet.
The first access enters the femoral vein at the groin and is extended superiorly to the right atrium. The second line enters the ipsilateral or contralateral femoral artery and advanced to the distal aorta. Deoxygenated blood is removed from the right atrium prior to being pumped through the ECLS device where it is oxygenated and returned as ...
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.
An occlusion of the artery would be seen by decreased or absent flow distal to the occlusion. Doppler ultrasound can even distinguish between embolic and thrombotic plaque. The former would show a delineated, round thrombus, whereas the latter would show narrowed arterial lumen with atherosclerotic plaque.
Specialized treatment – interventions such as hemodialysis, plasmapheresis, transvenous cardiac pacing, and invasive hemodynamic monitoring (e.g. pulmonary artery catheterization) require central venous access. There are no absolute contraindications to the use of central venous catheters. [3]
