Definition of varicose veins?
Dilated, tortuous superficial veins
Etiology/risk factors for varicose veins?
Increased age, female, genetics, standing, obesity
Pathogenesis of varicose veins?
Venous wall weakness + increased venous pressure _ valve incompetence
Clinical symptoms of varicose veins?
- Cosemetic issues
- Aching
- Skin ulcers
Definition of Raynaud’s phenomenon?
Arterial and arteriolar vasospasm
Etiology of Raynaud’s phenomenon
Cold, emotions
Epidemiology of raynaud’s phenomenon
females affected more than males
Pathogenesis of raynaud’s phenomenon
COld/emotions lead to arterial/arteriolar vasospasms in skin (fingers>toes, nose, ears)
Clinical symptoms of Raynaud’s phenomenon
Pallor, blue, red (bilateral, symmetrical); cold, parethesia, pain
Treatment of Raynaud’s phenomenon
prevention, calcium channel blockers, alpha blockers, vasodilators
Epidemiology of temporal arteritis (giant cell)
elderly, females more than males, most common vasculitiis
Etiology and pathogenesis of temporal arteritis/giant cell
Idiopathic
- Focal GRANULOMA formation in medium to large arteries.
- Branches of carotid (esp. temporal)>other arteries
Associations with temporal arteritis/giant cell
50% of patients have polymyalgia rheumatica
Clinical symptoms of temporal arteritis/giant cell
Unilateral throbbing temporal headache, +/- visual involvement, self-limiting (1-5 years)
How do you diagnose temporal arteritis/giant cell?
Increased ESR and CRP, biopsy, imaging
