However, because an erosion (in contrast to a rupture), is not an acute event, the clot often forms much more gradually. EC sloughing and neutrophil invasion occur secondarily to stasis-induced venous thrombosis, 4 and thrombi precipitated by plaque rupture can produce the appearance of plaque erosion in neighboring segments. 2 The idea that erosions are preceded by plaques deprived of large regions of its endothelial lining may thus be far too simple. Rather, processes of EC loss, neutrophil recruitment, and thrombosis may occur simultaneously facilitating growth of thrombus across an erosion-prone lesion Plaque erosion is placed most in the proximal segment and near a bifurcation of the left anterior descending artery. Near a bifurcation is anatomically the most significant predictor of plaque erosion.

Plaque erosion

Recent studies suggest that anti‐thrombotic therapy without stenting may be an option for this subset of patients. Currently, however, an invasive procedure is required to make a diagnosis of plaque erosion. Plaque erosion has three unique morphological characteristics — preserved vascular integrity, larger lumen area, and platelet-rich thrombus — which suggest that thrombus removal and effective Posts about plaque erosion written by dr s venkatesan. Retrospective angiographic studies and the prospective PROSPECT (Providing Regional Observations to Study Predictors of Events in the Coronary Tree) study have shown that plaques with severe stenosis carry a higher per-plaque risk for producing clinical events than plaques that cause no or non severe stenosis.

Plaque erosion occurs without cap disruption where flowing blood comes into direct contact with intimal surface lacking endothelial cells. 1 In both clinical studies using intravascular imaging and autopsy data from subjects dying suddenly, plaque erosion is the second most common cause of coronary thrombus.

A 69-year-old male presented with medically refractory vertebrobasilar insufficiency and paroxysmal subjective dizziness for six months. Severe stenosis of a dominant left V2 vertebral artery segment was identified on digital subtraction angiography (DSA) with an irregular intraluminal filling defect immediately above the stenosis. Optical coherence tomography (OCT) demonstrated a normal lumen

Pathological studies have shown that plaque erosion often develops on intimal thickening or a fibroatheroma, with few lipid core and calcification. The exposed intima at the eroded site is predominantly comprised of vascular smooth muscle cells and proteoglycans. The culprit lesions were classified as plaque rupture (PR), erosion (OCT-erosion), calcified nodule (OCT-CN), or with a new set of diagnostic criteria for OCT. Results: The incidences of PR, OCT-erosion, and OCT-CN were 43.7%, 31.0%, and 7.9%, respectively. Patients with OCT-erosion were the youngest, compared with those with PR and OCT-CN (53.8 ± 13.1 years vs.

Plaque calcification was present in 69% of ruptures versus 23% of erosions (P <.002). Plaque erosion is intimal injury which does not exhibit plaque rupture. Pathological studies have shown that plaque erosion often develops on intimal thickening or a fibroatheroma, with few lipid core and calcification. The exposed intima at the eroded site is predominantly comprised of vascular smooth muscle cells and proteoglycans. The culprit lesions were classified as plaque rupture (PR), erosion (OCT-erosion), calcified nodule (OCT-CN), or with a new set of diagnostic criteria for OCT.

Patients with OCT-erosion were the youngest, compared with those with PR and OCT-CN (53.8 ± 13.1 years vs. 60.6 ± 11.5 years, 65.1 ± 5.0 years, p = 0.005).
