All three results are often observed, at different locations, within the same individual.
This narrowing becomes more common after decades of living, increasingly more common after people are in their 30s to 40s. The endothelium the cell monolayer on the inside of the vessel and covering tissue, termed fibrous capseparate atheroma from the blood in the lumen.
If a rupture see vulnerable plaque of the endothelium and fibrous cap occurs, then both a a shower of debris from the plaque combined with b a platelet and clotting response to both the debris and at the rupture site occurs within fractions of a second. This is the principal mechanism of myocardial infarctionstroke or other related cardiovascular disease problems.
While clots at the rupture site typically shrink in volume over time, some of the clot may kista atheroma organized into fibrotic tissue resulting in narrowing of the artery lumen ; the narrowings sometimes seen on angiography examinations, if severe enough.
Artery enlargement[ edit ] If the muscular wall enlargement is overdone over time, then kista atheroma gross enlargement of the artery results, usually over decades of living.
This is a less common outcome. Atheroma within aneurysmal enlargement vessel bulging can also rupture and shower debris of atheroma and clot downstream. If the arterial enlargement continues to 2 to 3 times the usual diameter, the walls often become weak enough that with just the stress of the pulse, a loss of wall integrity may occur leading to sudden hemorrhage bleedingmajor symptoms and debility; often rapid death.
The main stimulus for aneurysm formation is pressure atrophy of the structural support of the muscle layers. The main structural proteins are collagen and elastin.
This causes thinning and the wall balloons allowing gross enlargement to occur, as is common in the abdominal region of the aorta. Most methods have focused on the openings of arteries; highly relevant, yet totally miss the atheroma within artery walls.
Historically, arterial kista atheroma fixation, staining and thin section has been the gold standard for detection and description of atheroma, after death and autopsy. With special stains and examination, micro calcifications  can be detected, typically within smooth muscle cells of the arterial media near the fatty streaks kista atheroma a year or two of fatty streaks forming.
Interventional and non-interventional methods to detect atherosclerosis, specifically vulnerable plaque non-occlusive or soft plaqueare widely used in research and clinical practice today. Carotid Intima-media thickness Scan CIMT can be measured by B-mode ultrasonography measurement has been recommended by the American Heart Association as the most useful method to identify atherosclerosis and may now very well be the gold standard for detection.
Lipoma & Kista Atheroma
Typically, such regions start occurring within the heart arteries about 2—3 decades after atheroma start developing. Hence the detection of much smaller plaques than previously possible is being developed by some companies, such as Image Analysis. Tumor ini sering meluas ke dalam otot maka kurang memberikan hasil yang baik dengan reseksi lokal.
Tumor ini terdiri dari jaringan lemak yang immature. Kista atheroma Simetris Madelung Sering dijumpai pada daerah kepala, leher, bahu dan proximal extremitas atas.
Lipoma & Kista Atheroma
Pada anamnesa sering terdapat riwayat mengkomsumsi alkohol atau penyakit diabetes mellitus. Biasanya terdapat pada daerah extremitas dan timbul setelah pubertas.
Pada anamnesa didapatkan riwayat penyakit yang sama pada keluarga. Penyakit Dercum Adiposis Dolorosa Lipoma yang menimbulkan rasa nyeri. Biasanya dijumpai pada wanita postmenopausa yang obese ,alcoholism, ketidakstabilan emosi dan depresi berasosiasi dengan penyakit ini.
Angiolipoma Angiolipoma adalah nodul subkutan yang kenyal dan nyeri. Tumor ini lebih keras daripada lipoma biasa dan multilobulasi.
Hibernomas Tumor ini tumbuh kista atheroma, nodul yang berbatas tegas dan biasanya asimptomatik.
