Many factors can interfere with normal blood flow: heart failure or physical inactivity may retard circulation generally; a change in the shape or inner surface of a vessel wall may impede blood flow, as in atherosclerosis ; a mass may grow inside the body and exert pressure on a vessel; the vessel wall may be injured and roughened by an accident, surgery, a burn, cold, inflammation, or infection; or the blood may thicken in reaction to the presence of a foreign serum or snake venom. Sometimes a thrombus detaches itself from the wall and is carried along by the bloodstream. Such a clot is called an embolus , and the condition is known as embolism. A thrombus may form in the heart chambers, such as after coronary thrombosis see below at the place where the wall of the heart is weakened, or in the dilated atria in a case of mitral stenosis. Because blood normally flows more slowly through the veins than through the arteries, thrombosis is more common in veins than in arteries. Venous Thrombosis.

Intracerebral hemorrhage ICH , also known as cerebral bleed and intraparenchymal bleed , is a sudden bleeding into the tissues of the brain , into its ventricles , or into both. Symptoms can include headache , one-sided weakness, vomiting, seizures, decreased level of consciousness , and neck stiffness. Causes include brain trauma , aneurysms , arteriovenous malformations , and brain tumors. Treatment should typically be carried out in an intensive care unit. Cerebral bleeding affects about 2. People with intracerebral bleeding have symptoms that correspond to the functions controlled by the area of the brain that is damaged by the bleed. A severe headache followed by vomiting is one of the more common symptoms of intracerebral hemorrhage.
