With a brief pause in chest compressions, a modified Seldinger technique is used to access both the femoral artery and femoral vein with the assistance of ultrasound. In the CHEER trial [19] 15Fr arterial cannulae and 17Fr venous cannulae [21] (Medtronic, Minneapolis, MN USA) were used. The arterial cannula is advanced to the descending aorta ...
The tip of the femoral venous cannula should be maintained near the junction of the inferior vena cava and right atrium, while the tip of the femoral arterial cannula is maintained in the iliac artery. [26] In adults, accessing the femoral artery is preferred because the insertion is simpler. [26]
The Mynx vascular closure device is an extravascular vascular closure device (VCD) whose deployment system is designed to minimize the discomfort commonly associated with closing the small hole in the artery following catheterization procedure. The device is manufactured by AccessClosure, Inc., a medical device company located in Mountain View ...
A venous cannula removes oxygen depleted venous blood from a patient's body, and an arterial cannula infuses oxygen-rich blood into the arterial system. The main determinants of cannula size selection is determined by the patient's size and weight, anticipated flow rate, and the size of the vessel being cannulated. [10]
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]
Endovascular procedure can be performed achieving access in to body’s arterial system from either femoral artery (in groin), brachial artery (in elbow) or radial artery in the wrist. The transfemoral (through groin) approach to perform cardiac catheterization has typically been more prevalent in invasive cardiology.
It is placed within a silicone cannula for protection. A steel cable is connected to it which drives it. Lubrication is fed to the pump through a catheter in the drive cable. The pump is inserted through the femoral artery, and then moved up until the tip of the cannula passes over the aortic valve. [1] The pump is powered by a magnet ...
The standard pulmonary artery catheter has two lumens (Swan-Ganz) and is equipped with an inflatable balloon at the tip, which facilitates its placement into the pulmonary artery through the flow of blood. The balloon, when inflated, causes the catheter to "wedge" in a small pulmonary blood vessel.
