If a clot forms or becomes lodged in an artery, it can cut off blood flow to the heart or part of the brain, causing a heart attack or a stroke. ... But venous blood clots kill more people than ...
A surgeon opens the skull and then the dura mater; removes the clot with suction or irrigation; and identifies and controls sites of bleeding. [28] [29] The injured vessels must be repaired. Postoperative complications can include increased intracranial pressure, brain edema, new or recurrent bleeding, infection, and seizures.
It can result in dangerous increases in ICP and can cause potentially fatal brain herniation. [1] Even independently, IVH can cause morbidity and mortality. First, intraventricular blood can lead to a clot in the CSF conduits blocking its flow and leading to obstructive hydrocephalus which may quickly result in increased intracranial pressure ...
The bleed can be very small without any significant effect on surrounding brain or large hemorrhage that exerts mass effect on adjacent brain. Follow up CT scan is recommended. Those with extension of bleed into the ventricular system , expansion of bleeding, or increasing cerebral oedema on CT scan gives poorer prognosis.
And when stroke patients are taken to an emergency room, the first treatment doctors often consider is a clot-dissolving medicine called tPA, which can make brain bleeding worse.

Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
Brain oedema formation is due to the breakdown of red blood cells, where haemoglobin and other contents of red blood cells are released. The release of these red blood cells contents causes toxic effect on the brain and causes brain oedema. Besides, the breaking down of blood-brain barrier also contributes to the odema formation. [13]
