Why is the metaphysis predisposed to embolus formation?
The nutrient arteries near the epiphyseal cartilage are nonanastomosing, thereby allowing any blockage to produce tissue necrosis and the sinusoids (venous side of capillary) have slow, turbulent flow predisposing to thrombosis.
What is a venous duct?
The venous duct connects the umbilical arteries to the liver.
What is the physiology of venous insufficiency?
Syndromes related to venous insufficiency are caused by valve incompetence. Venous insufficiency is a chronic (long term) condition
What drains venous blood from the brain and delivers it to the internal jugular veins?
dural venous sinuses
What is central venous pressure?
Normal central venous pressure is in the range of 2-8 cmH2O.
What does the medical term stasis mean?
In medical terms, stasis means lack of movement. For example, venous stasis is a relative lack of flow or slow flow in the veins.

What is the condition where normal blood flow is slowed or halted?
Coagulation or clotting means to stop blood flow.
What are the differences between arterial and venous thrombosis?
Arterial thrombosis is associated with an atherosclerotic plaque being ruptured. It is hence associated with high pressure arteries. The thrombus is made of many platelets and contains little fibrin. It can lead to stroke or acute myocardial infarction in the most severe cases. Venous thrombosis is caused by vessel injury or static blood flow in a low-pressure venous system. The thrombus is made of fibrin and red blood cells with very little platelets. It can detach to form an embolus and may cause pulmonary embolism.
What is the medical term meaning Inflammation of a vein with a thrombus?
Thrombophlebitis is the medical term meaning a clot forms in a vein, and inflammation around the vein results.thrombophlebitis
What is the purpose of having an elevated injured leg?
Elevating an injured leg prevents venous stasis and oedema from forming. Prevention of these processes requires the leg to be mobile to overcome gravity. When your leg is immobile it is important to utilise gravity to prevent these processes from occurring.
What causes venous ulcer?
Venous ulcer are caused by venous insufficiency (improper functioning of venous valves).
What is the difference between an ulcer and blister?
Wounds occur due to trauma by external means accidental or intentional, by contact or radiation Ulcers occur as a result of an underlying or internal etiology, eg: A venous leg ulcer is the consequence of venous stasis.
How to treat Leg Discoloration?
Leg Discoloration Venous stasis dermatitis, or darkening of skin on of the lower legs, is a common sign of underlying vein disease (even if varicose veins are not present). The change in pigmentation to a dark color usually occurs around the feet or ankles. It can be a sign of a potentially more advanced disease and can lead to thinning of the skin and even eventual ulceration. Signs of Venous Stasis Dermatitis skin around the ankles has a looks reddish, yellowish or a brown color. associated swelling around the ankle area. itching/pain. a thickening of skin around the ankles or shins. hair loss on the ankle or shins in the associated area. Treatment The solution is to evaluate the underlying venous disease. The underlying venous disease can be treated by a combination of modalities Radio Frequency Ablation, VenaSeal, Sclerotherapy). Over time, the discoloration will gradually improve and become less noticeable. WhatsApp Image 2021-10-18 at 10.38.38 AM
