Before we can properly discuss hyaline arteriosclerosis, we need to be onboard with some very basic but important definitions and anatomy. 28.23b Pericardial Disease Pathology. There are two variants. Vascular Pathology in Hypertension. 1. Rare foci of parenchymal microhemorrhages and necrosis were also observed. ภาวะหลอดเลือดโป่งพอง (Aneurysm) 1.3. It also has a pink color under the microscope when a routine, H&E, stain is used to visualize it. Arteriolosclerosis is a form of cardiovascular disease involving hardening and loss of elasticity of arterioles or small arteries and is most often associated with hypertension and diabetes mellitus. 3. Hyaline Arteriolosclerosis. The pathogenesis Vascular Diseases. Hyperplastic Arteriolosclerosis:o Characteristic of malignant hypertension(diastolic pressures usually over 120 mm Hg).o Onionskin concentric laminated thickening of wallsof arterioles with progressive narrowing of lumina.o Electron microscope: the laminations consist of SMCsand thickened and reduplicated basement membrane. Histology showed fibrinoid necrosis of arteriolar walls. Mönckeberg’s medial calcific sclerosis 1.2. The sclerosis lesion is due to thickening of the smooth muscle wall, often resulting in an onion skinned appearance. Hyperplastic arteriolosclerosis was defined as arteriolar concentric medial smooth muscle hyperplasia and basement membrane duplication (Fig. Hyalin has a characteristic morphologic appearance, staining bright magenta with periodic acid-Schiff (PAS) stain and having a glassy texture. Hypertension associated degenerative changes in the walls of large and medium arteries can potentiate both aortic dissection and cerebrovascular hemorrhage. There are two types: 1. hyaline arteriolosclerosis 2. hyperplastic arteriolosclerosis Seen in the elderly, hyper Atherosclerosis 1.1.3. Arteriolosclerosis.

Hyperplastic arteriolosclerosis was defined as arteriolar concentric medial smooth muscle hyperplasia and basement membrane duplication . Arteriolosclerosis is characterized by thickening of the walls of small arteries and arterioles. 12 terms. 4. These changes represent an adaptive response of arterioles to severe (“malignant”) hypertension. There are two subtypes of this disease. Hyperplastic arteriolosclerosis is a type of arteriolosclerosis involving a narrowed lumen. Hyperplastic arteriolosclerosis: It is characterized by thickening of the arteriolar wall due to the concentric proliferation of smooth muscle cells, giving the arterioles an “onion skin” appearance. These changes represent an adaptive response of arterioles to severe (“malignant”) hypertension. JPC SYSTEMIC PATHOLOGY CARDIOVASCULAR SYSTEM April 2019 C-M05. 2.
