A pseudoaneurysm, being associated with a vessel, can be pulsatile; it may be confused with a true aneurysm or dissecting aneurysm. The most common presentation of pseudoaneurysm is femoral artery pseudoaneurysm following access for an endovascular procedure, [1] and this event may complicate up to 8% of vascular interventional procedures ...
Increased blood pressure in the veins (venous hypertension) can cause diffusion of substances, including fibrin, out of capillaries. Fibrotic tissue may predispose the tissue to ulceration. Recurrent ulceration and fat necrosis is associated with lipodermatosclerosis. In advanced lipodermatosclerosis the proximal leg swells from chronic venous ...
Ultrasonography of chronic venous insufficiency of the legs allows the examiner to evaluate the gross anatomy of the venous networks as well as the blood flow direction, which is crucial in determining vein pathology. It has become the reference standard used in the assessment of the condition and hemodynamics of the veins of the lower limbs.
Peripheral artery disease – occurs when atheromatous plaques build up in the arteries that supply blood to the arms and legs, causing the arteries to narrow or become blocked. [ 1 ] Erythromelalgia - a rare peripheral vascular disease with symptoms that include burning pain, increased temperature, erythema and swelling that generally affect ...
Weakened Venous valves: these are crucial towards ensuring upward flow to the heart from the lower extremities. If weakened, they may fail to close properly which leads to backwards blood flow/blood pooling. This can lead to slower blood flow in the veins. [8] Ultrasonography-Doppler ultrasound
Also, blood clots may form on the inside of ventricular aneurysms, and form embolisms. If such a clot escapes from the aneurysm, it will be moved in the circulation throughout the body. If it gets stuck inside a blood vessel, it may cause ischemia in a limb, a painful condition that can lead to reduced movement and tissue death in the limb. [1]
This is an incomplete list, which may never be able to satisfy certain standards for completion.. There are many conditions of or affecting the human circulatory system — the biological system that includes the pumping and channeling of blood to and from the body and lungs with heart, blood and blood vessels.
Critical ischemia is produced when the reduction in blood flow results in a perfusion deficit at rest and is defined by the presence of pain at rest or trophic lesions in the legs. In this situation, precise diagnosis is fundamental, as there is a clear risk of loss of the limb if adequate blood flow is not re-established, either by surgery or ...
