| vascular tunic of eye | The vascular, pigmentary, or middle coat of the eye, comprising the choroid, ciliary body, and iris. Synonym: tunica vasculosa bulbi, Haller's tunica vasculosa, tunica vasculosa oculi, uvea, uveal tract. (05 Mar 2000) |
| vascular zone | An area in the external acoustic meatus where a number of minute blood vessels enter from the mastoid bone. Synonym: spongy spot, zona vasculosa. (05 Mar 2000) |
| resistance, vascular | The opposition to the flow of blood across a vascular bed. (12 Dec 1998) |
| peripheral vascular disease | A term used to describe progressive occlusive disease of the arteries that supply the extremities. Risk factors include atherosclerosis and diabetes. (27 Sep 1997) |
| peripheral vascular diseases | General or unspecified diseases of the blood vessels outside the heart. It is for diseases of the peripheral as opposed to the cardiac circulation. (12 Dec 1998) |
| choroidal vascular atrophy | Atrophy affecting either all choroidal vessels or only the choriocapillaris, occurring either diffusely or confined to the posterior pole of the eye. (05 Mar 2000) |
| collagen-vascular diseases | A group of generalised disease's affecting connective tissue and frequently characterised by fibrinoid necrosis or vasculitis; in some collagen disease's, auto-immunization, particularly antinuclear antibodies, has been shown and circulating immune complexes are found. The term is not entirely acceptable because there is no evidence that collagen is primarily involved; "collagen" was once synonymous with "connective tissue" rather than describing a specific fibrinous protein in that tissue. See: connective-tissue diseases. (05 Mar 2000) |

| Haller's vascular tissue | <anatomy> The outer portion of the choroid of the eye containing the largest blood vessels. Synonym: lamina vasculosa choroideae, Haller's vascular tissue, uvaeformis, vascular layer of choroid coat of eye, vascular layer. (05 Mar 2000) |
| skin diseases, vascular | Skin diseases affecting or involving the cutaneous blood vessels and generally manifested as inflammation, swelling, erythema, or necrosis in the affected area. (12 Dec 1998) |

| dementia, vascular | An organic mental disorder caused by systemic vascular disease such as arteriosclerotic changes in the vessels, valvular heart disease, hypertension, etc., and resulting in cerebral vascular disease with dementia. (12 Dec 1998) |
| systemic vascular resistance | An index of arteriolar compliance or constriction throughout the body; equal to the blood pressure divided by the cardiac output. (05 Mar 2000) |
| encephalotrigeminal vascular syndrome | <syndrome> Angiomatosis of the brain accompanied by nevi in the trigeminal area. See: Sturge-Weber syndrome. (05 Mar 2000) |
