Vascular clinical knowledge Flashcards
What are the basic anatomy of vascular venous system?
Deep venous system located under the fascia of the lower limb accomanying major arteries darining the lower extremities
Suerficial venus syste in subcutaneous tissue drain cutaneous microcirculation into deep system connected with deep system via series of perforators
What are the characteristics of the venous system in legs?
Low pressurehigh volume valves to help pump blood back to the heart.
What are the sperfiial veins of the leg?
The great saphenous vein principal vein of medial superficial system and small saphenouse vein in the posteria calf that drains into popleteal vein
Where do the deep veins run?
In the muscular layer of the leg
What are the deep veins of the leg?
Deep femoral Anteria tibia posterior tibial
What is venouse insufficiency?
failure of lower extremity muscle pump. Outflow obstruction, musculo-fascial wekness, loss of joint motion, valvular failure leading to deep venous incompetance
What is likely to cause primary valvular incompetence in superfeicial veins?
increased collagen and decreased smooth muscle and elastin in wall, dilatation of weakened walls leads to valvular incometance
What is the difference between primary and secondary venouse disease?
Primary s reculx but secondary is reflux and obstruction
What is an acute venous disease?
Deep vein thrombosis pain oedema tenderness
What are investigation for chronic vnous disease?
USS doppler studies imaging modality of choice
How can Chronic venous disase be classified?
CEAP
Clinical etioogical
Anatomica
Pathophysiological
How is chronic venous disease classified in terms of clinical?
no visible or palpable signs of venous disease. Telangiectases or reticular veins, varicouse veins, oedea pigmentation or lipodermato sclerosis, hard venouse ulcer active venous ulcer
How is chronic venous disease classified in terms of etiological?
Congenital Primary Secondary no venous cause
How is chronic venous disease classified in terms of anatomical?
superficial deep perforator no venouse location identified
How is chronic venous disease classified in terms of pathophysiological?
Reflux obstruction/thrombosis. reflus and opstruction or no venouse patholoy identified
