Dr. Chopra Vascular Clinic is a healthcare Clinic which provides a service concerned with the diagnosis, treatment and prevention of diseases affecting arteries Minkah Fitzpatrick Jersey , veins and lymphatics. Anatomy Veins bring blood back to the heart against gravity (when erect), a distance of 3-4 ft. The main system carrying 95% of the venous return is the deep system situated near the bones. The superficial system is present below the skin and dilates (varicose veins). There are also interconnecting veins between these two systems Kenny Stills Jersey , called perforators. The deep system comprises:
鈥?Soleal sinusoids 鈥?Tibial veins 鈥?Popliteal vein 鈥?Femoral vein The superficial system comprises:
鈥?Dorsal venous arch 鈥?Long saphenous vein 鈥?Short saphenous vein 鈥?Posterior arch vein 鈥?Perforator veins 鈥?Giaccomini vein 鈥?Other tributaries. 鈥? Veins of the legs have one way valves.
How veins work Blood moves in the arteries by the pumping action of the heart. When lying, gravity is eliminated and blood is pushed back by the pressure of the arterial blood. When walking it has to move against gravity. The calf muscles (external heart) compress the venous sinusoids and force blood back in the deep veins. During relaxation of the muscles the blood would fall to the feet but this is prevented by the presence of one way valves in the veins. Abnormal valves Venous insufficiency can occur due to problems in the veins themselves or weakness of the pumping mechanism of the calf. The two can cause leaky valves. Turbulent flow may cause weakness of the vein at various points causing them to varicose.
The main causes are:
鈥?Congenital abnormalities of veins 鈥?DVT damaging valves of deep system 鈥?Superficial vein incompetence.
DVT causes inflammation of the vein Cameron Wake Jersey , damaging the valves. So when clot dissolves it leaves a damaged leaky valve. Now the muscles of the calf have to do more work to pump the blood back. Ultimately they weaken and lead to pooling of the blood - swelling, varicose veins Reshad Jones Jersey , dermatitis and ulcers. DVT is more common in:
