Question
In addition to increasing intracranial pressure, a sub-arachnoid hemorrhage may also lead to….?Question 15Answera.Pulmonary hypertension.b.Portal hypertension.c.Vasospasm of arteries supplying the brain, causing ischemia.d.Extensive death of neurons due to bleeding inside the brain.e.Formation of berry aneurysms in the circle of Willis.
Solution
A sub-arachnoid hemorrhage can lead to several complications, including:
c. Vasospasm of arteries supplying the brain, causing ischemia: This is a common complication of sub-arachnoid hemorrhage. The blood released into the subarachnoid space can cause the arteries to spasm, reducing blood flow to areas of the brain and leading to ischemia, or insufficient blood supply.
d. Extensive death of neurons due to bleeding inside the brain: The bleeding associated with a sub-arachnoid hemorrhage can cause pressure and damage to the brain tissue, leading to the death of neurons.
e. Formation of berry aneurysms in the circle of Willis: While a berry aneurysm is often the cause of a sub-arachnoid hemorrhage, it can also be a result. The pressure from the hemorrhage can cause weak spots in the blood vessels to bulge out and form an aneurysm.
Pulmonary hypertension (a) and portal hypertension (b) are not typically associated with a sub-arachnoid hemorrhage.
