The cause of death was revealed to be acute fat embolism, which resulted from the blunt force impact caused by the beatings, which led to the fatty tissue entering the bloodstream and eventually entering the blood vessels in the lungs, which led to a blockage and cut off the circulation of oxygenated blood and led to Ee's death by respiratory ...
Possible secondary causes of cerebral vasculitis are infections such as with varicella zoster virus (chicken pox or shingles), systemic auto-immune diseases such as systemic lupus erythematosus (SLE) and rheumatoid arthritis, medications and drugs (amphetamine, cocaine and heroin), some forms of cancer (lymphomas, leukemia and lung cancer) and ...
For spontaneous intracerebral hemorrhage seen on CT scan, the death rate is 34–50% by 30 days after the injury, [22] and half of the deaths occur in the first 2 days. [51] Even though the majority of deaths occur in the first few days after ICH, survivors have a long-term excess mortality rate of 27% compared to the general population. [ 52 ]
Atrial fibrillation causes blood clots to form within the heart, which may travel to the arteries within the brain and cause an embolism. The embolism prevents blood flow to the brain, which leads to a stroke. [26] An aneurysm is an abnormal bulging of small sections of arteries, which increases the risk of artery rupture.
The patterns of draining veins from the fistula determines the risk of DAVF rupture. Increased pressure within the dural venous sinuses causes backpressure into the cortical veins, thus making cortical veins more prone to rupture. The risk of hemorrhage is graded by Cognard and Borden grading systems. These grading systems are based upon the ...
For intraparenchymal hemorrhage associated with hypertension, small holes in arteries are thought to cause bleeding in the deep penetrating arteries of the brain, which are smaller and thinner than other arteries. These are the arteries that supply blood to the basal ganglia, the thalamus, the brainstem, and deep portions of the cerebellum ...
DVT usually occurs in the veins of the legs, although it can also occur in the veins of the arms. Immobility, active cancer, obesity, traumatic damage and congenital disorders that make clots more likely are all risk factors for deep vein thrombosis. It can cause the affected limb to swell, and cause pain and an overlying skin rash.
This causes the endothelial cells of the blood vessels to express adhesion factors which encourages the clotting of blood and formation of thrombus. [52] Sickle-cell anemia, which can cause blood cells to clump up and block blood vessels, can also lead to stroke. Stroke is the second leading cause of death in people under 20 with sickle-cell ...
