In polyarteritis nodosa, small aneurysms are strung like the beads of a rosary, [4] therefore making this "rosary sign" an important diagnostic feature of the vasculitis. [5] The 1990 ACR criteria were designed for classification purposes only, but their good discriminatory performances, indicated by the initial ACR analysis, suggested their ...
Fibromuscular dysplasia (FMD) is a non-atherosclerotic, non-inflammatory disease of the blood vessels that causes abnormal growth within the wall of an artery. [1] FMD has been found in nearly every arterial bed in the body, although the most commonly affected are the renal and carotid arteries. [1] [2] [3]
Polyarteritis nodosa: Mononeuritis multiplex, nodules, purpura, livedo, and hypertension. [11] Kawasaki disease: Fever, conjunctivitis, exanthema, palmoplantar erythema, cervical lymphadenopathy, and mucosal enanthema. [12] [13] Primary small vessel antineutrophil cytoplasmic antibody (ANCA)–associated vasculitis [8] Microscopic polyangiitis
Polyarteritis nodosa can be verified by looking for aneurysms in the renal and mesenteric arteries. While conventional angiography remains the accepted standard diagnostic modality, there is potential for superiority with computed tomography angiography and magnetic resonance angiography , as they can offer important insights into intraluminal ...
Arterial dysplasia is a term that refers to a group of conditions that affect the structure and function of the arteries. [1] One of the most common types of arterial dysplasia is fibromuscular dysplasia .
It may imitate, and is in turn imitated by, a number of other diseases that affect the blood vessels of the brain diffusely such as fibromuscular dysplasia and thrombotic thrombocytopenic purpura. [3] Primary CNS vasculitis has an incidence of 2.4 cases per 1 million people, with an associated mortality of 8-23% and a 25% risk of severe ...
The study was designed to assess the effects of informational vs. asymmetrically paternalistic approaches to encouraging low-calorie meal choices. The informational manipulations were (1) providing recommendations for daily caloric consumption for a person of
Renal artery stenosis (RAS) is the narrowing of one or both of the renal arteries, most often caused by atherosclerosis or fibromuscular dysplasia.This narrowing of the renal artery can impede blood flow to the target kidney, resulting in renovascular hypertension – a secondary type of high blood pressure.
