Vascular pathology in HT and complication of HT on bv

HT can be categorized in 2 severity-based which are benign HT and malignant HT

vascular pathology in benign HT

hyaline arteriosclerosis

1. pink, homogenous hyaline thickening
2. leakeage of plasma protein across endothelial cells
3. production of excessive ECM by smooth ms cells

vascular pathology in malignant HT

hyperplastic arteriosclerosis

1. onionskin, concentric, laminated smooth ms with progressive narrowing of lumen
2. thickening of the smooth ms cells
3. reduplication of basement membrane
4. accompanied by fibroid necrosis (pink appearance, severely damaged small arteries and arterioles)

HT can lead to

• atherosclerotis
• aneurysm of bv
• dissecting aneurysm
