A ruptured aneurysm may be associated with other complications, such as:
- Cerebral vasospasm. After an aneurysm rupture, your brain’s blood vessels may rapidly constrict, cutting off blood flow to brain cells and resulting in further damage.
- Hydrocephalus. A ruptured aneurysm may cause a subarachnoid hemorrhage (see above). This leads to bleeding in the space between your brain and surrounding tissue, which disrupts the circulation of the cerebrospinal fluid surrounding your brain and spinal cord. The result is increased pressure on the brain and more damage.
- Hyponatremia. Bleeding in the brain can disrupt the amount of sodium in your blood and lead to swelling.
- Re-bleeding. A ruptured aneurysm may start bleeding again, leading to further tissue damage.
All of these complications can lead to permanent brain damage. Getting immediate medical attention is essential for avoiding these complications.
