Non-occlusive thrombosis may also cause rapid increases in the size of atherosclerotic plaques as a result of platelet activation and elaboration of platelet-derived growth factors (PDGF) on the surface of the plaque. 138, Issue 3542, pp. PATHOGENESIS. THE pathogenesis of thrombosis in man is still to a considerable extent a mystery despite the considerable advances in knowledge of the subject in recent years. Owing to its multifactorial nature, however, management of this condition remains a challenge. Lindboe, MD We histologically examined specimens from 11 patients with recent occluding thrombi at the carotid bifurcation to study local factors in the vessel wall that precipitated the thrombi. If the clot breaks loose and travels through the bloodstream, it is a thromboembolism. These grow by apposition (8 +C) to occlude more and larger ve nous vessel segments. /�%�'��R_砣ґ�� tԭƖ/��H8���%3��J
