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 the arteries and veins within the body. PAD differs from peripheral veinous disease. PAD means the ...
Arterial occlusion is a condition involving partial or complete blockage of blood flow through an artery. Arteries are blood vessels that carry oxygenated blood to body tissues. [ 1 ] [ 2 ] An occlusion of arteries disrupts oxygen and blood supply to tissues, leading to ischemia . [ 1 ]
This is a shortened version of the sixth chapter of the ICD-9: Diseases of the Nervous System and Sense Organs. It covers ICD codes 320 to 389. The full chapter can be found on pages 215 to 258 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
Moyamoya disease is a disease in which certain arteries in the brain are constricted. Blood flow is blocked by constriction and blood clots (). [2]A collateral circulation develops around the blocked vessels to compensate for the blockage, but the collateral vessels are small, weak, and prone to bleeding, aneurysm and thrombosis.
[10] Lung: Pulmonary infarction or lung infarction; Spleen: Splenic infarction occurs when the splenic artery or one of its branches are occluded, for example by a blood clot. Although it can occur asymptomatically, the typical symptom is severe pain in the left upper quadrant of the abdomen, sometimes radiating to the left shoulder.
Ischemia is a vascular disease involving an interruption in the arterial blood supply to a tissue, organ, or extremity that, if untreated, can lead to tissue death. It can be caused by embolism, thrombosis of an atherosclerotic artery, or trauma. Venous problems like venous outflow obstruction and low-flow states can cause acute arterial ischemia.
Angiography is commonly used in the diagnosis of Takayasu arteritis, [4] especially in the advanced stages of the disease, when arterial stenosis, occlusion, and aneurysms may be observed. [4] However, angiography is a relatively invasive investigation, exposing patients to large doses of radiation, [ 4 ] so is not recommended for routine, long ...
TOS can be related to cerebrovascular arterial insufficiency when affecting the subclavian artery. [8] It also can affect the vertebral artery, in which case it could produce vision disturbances, including transient blindness, [9] and embolic cerebral infarction. [10]
