Case study Barbara .K. Dudas – 4259456 12/05/15 Greg Thiessen, BIOL 1180 Niagara College Canada Bruce is a 55-year-old college professor who teaches a night class in a small town about 50 miles from his home. One night, as he walked to his car after class, Bruce noticed that his right leg was uncomfortable. When he arrived home, about 90 minutes later, Bruce realized that the calf of his right leg had become very swollen. When he extended his knee and plantar flexed his foot, the pain in his right leg increased. Bruce thought this might be a serious condition, so he drove to the hospital. In the emergency room, technicians performed a Doppler test, which monitors the flow of blood through blood vessels. The test confirmed that…show more content…
Frequent blood samples were taken to determine Bruce’s prothrombin time. After about a week, Bruce was released from the hospital. His physician, however, prescribed oral Coumadin for at least several months. In addition, Bruce was required to have his prothrombin time checked periodically. Explain why edema and pain developed in response to a thrombus in a deep vein of Bruce’s right leg. (4 marks) The blocked vein in Bruce’s right led caused an edema, which can be described as an excess of watery fluid collecting in the cavities or tissues of the body. The edema led to an inadequate amount of blood supply known as tissue ischemia (Bollensdorff, 2011). The Edema had developed inferior to the blocked vein and blockage of the vein increased the capillary hydrostatic pressure (Marieb, 2015). This 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. This means that the fluid accumulated in the tissue space and caused the edema (Rodgers, 2000). The ischemia resulted in pain, much in the same way that a myocardial infarction does (Marieb, 2015). If a thrombus in the posterior tibial vein gave rise to an embolus, name in order the parts of the circulatory system the embolus would pass through before lodging in a blood vessel in the lungs. Explain why the lungs are the most likely places the
