Case Study Bruce's Right Leg

Bruce’s right leg. (4 marks)
Deep vein thrombosis refers to the formation of a blood clot in a deep vein in the leg. Deep vein thrombosis tends to occur in leg veins, such as the popliteal or femoral veins, as well as deep veins within the pelvis. The blocked vein in Bruce’s right led caused edema and led to tissue ischemia. Edema developed inferior to the blocked vein. Blockage of the vein increased the capillary hydrostatic pressure increased the amount of fluid that flowed from the capillaries into the tissue spaces and reduced the amount of fluid that returned to the capillaries. So the fluid accumulated in the tissue space and caused the edema. The ischemia resulted in pain, also in the way that ischemia of the heart causes pain during
Emboli will lodge in the branches of the pulmonary arteries. Emboli will most likely to lodge in the lungs because the pulmonary arteries branches many times before they deliver blood to the pulmonary capillaries and as they branch, their diameters decrease. Even small emboli will eventually lodge in the in the smaller branches of the pulmonary arteries. The other parts of the circulatory system through which the emboli pass through have much larger diameters and emboli can pass readily through
If blood flow through the lungs to the left side of the heart is reduced significantly, hypertension can develop. Reduced blood flow to the left side of the heart will result in reduced cardiac output because of the decreased venous return (starling law of the heart). As a result, blood pressure falls and the mechanism that regulate blood pressure are activated(regulation of mean arterial pressure. Manifestations of hypotension, such as increased heart rate, a weak pulse, and pallor may be
