Study Notes
Vessel Access
- Percutaneous access involves puncturing a vessel.
- Cutdown is a minor surgical procedure isolating a vessel for catheter insertion.
- Common percutaneous insertion sites include femoral, brachial, and axillary arteries.
Percutaneous Access
- Techniques include femoral, brachial, and axillary approaches for access to blood vessels.
- These sites are used for various procedures including interventions on blood vessels in the lower limbs, pelvic area, abdominal aorta and branches, thoracic aorta, brachiocephalic vessels, coronary arteries, and the left ventricle of the heart.
Peripheral Vascular Disease
- Iliac artery narrowing due to plaque can cause intermittent claudication (leg pain) in the lower leg.
- Aorto-bifemoral bypass, femoral-popliteal bypass, and femoro-femoral crossover are surgical procedures used for peripheral vascular disease.
Aneurysms
- A femoral aneurysm is a bulge in the femoral artery.
- Aneurysms can also be in the neck, and dome portions of arteries. Surgical intervention is needed.
Brachial Artery
- The brachial artery is a major artery in the upper arm.
- It is a useful vessel for various procedures.
- Procedures include brachial artery access for catheters.
- Relevant anatomy includes the median, ulnar, and radial nerves, and the biceps muscle.
- The left and right brachial arteries stem from the left and right vertebral arteries and contribute to the basilar artery and posterior fossa.
Axillary Artery
- The axillary artery is a vessel in the armpit area.
- It relates to the brachial plexus.
- Access is a procedure with the potential for the descending aorta, abdominal aorta, pelvic area, as well as lower extremities procedures.
- The right axillary artery has a connection with the ascending aorta, left ventricle of the heart and a possible coronary artery, and a four vessel study pertaining to the cerebral vessels.
Seldinger Technique
- A technique for introducing catheters into blood vessels.
- It involves puncturing the vessel, inserting a guidewire, passing a sheath over the guidewire, removing the guidewire and threading the catheter into the vessel through the sheath.
- It provides safe access to blood vessels and other hollow organs.
- Dr. Sven Ivar Seldinger introduced the technique in 1953.
