Peripheral artery disease most commonly affects the legs, but other arteries may also be involved, such as those of the arms, neck, or kidneys. [4] [17] Peripheral artery disease (PAD) is a form of peripheral vascular disease. Vascular refers to both the arteries and veins within the body. PAD differs from peripheral veinous disease. PAD means ...
Peripheral artery disease is typically diagnosed if the systolic blood pressure in the ankle divided by the systolic blood pressure in the arm is less than 0.9. In general, claudication is often seen in people with an ABI between 0.4 and 0.9, rest pain is seen between 0.2 and 0.4, and tissue loss, ulcers, and gangrene between 0 to 0.4.
In treating renal artery disease, a 2014 study indicates that balloon angioplasty can improve diastolic blood pressure and potentially reduce antihypertensive drug requirements. [30] In the case of peripheral artery disease, treatment to prevent complications is important; without treatment, sores or gangrene (tissue death) may occur. [citation ...
If these liquid pockets are close enough to the interface between the vitreous gel and the retina, they can cause complete separation of the vitreous from the retina in a normally occurring process in older humans called posterior vitreous detachment (PVD). PVD in of itself is not dangerous and a natural process. [citation needed]
Femoropopliteal bypass surgery is mainly used to treat cases of femoral artery blockage that cause more severe symptoms that restrict completion of daily tasks such as peripheral artery disease and claudication, or cases that have not responded well to other treatment options . Before surgery is considered, adjustments are made to lifestyle ...
Potential complications [ edit ] A pulmonary embolism (PE) occurs when a blood clot from a deep vein (a DVT) detaches from a vein ( embolizes ), travels through the right side of the heart, and becomes lodged as an embolus in a pulmonary artery that supplies deoxygenated blood to the lungs for oxygenation.

Acute limb ischaemia (ALI) occurs when there is a sudden lack of blood flow to a limb [1] within 14 days of symptoms onset. [2] On the other hand, when the symptoms exceed 14 days, [3] it is called critical limb ischemia (CLI).
A posterior vitreous detachment (PVD) is a condition of the eye in which the vitreous membrane separates from the retina. [1] It refers to the separation of the posterior hyaloid membrane from the retina anywhere posterior to the vitreous base (a 3–4 mm wide attachment to the ora serrata ).
