A patient may spend 1 to 4 weeks in the hospital. The stay depends on the amount of damage caused by the aneurysm. The patient's health and response to treatment also affect the length of the stay. The healthcare team will monitor how well treatment has worked. Then they will decide whether rehabilitation is needed.

Evaluating the Outcome

Follow-up tests may be done 3 to 5 days after treatment. These tests show how well the treatment worked.

When to Call the Surgeon

Call the surgeon right away if you notice any of the following in your loved one:

  • A seizure
  • A severe headache
  • Any loss of function
  • A high or long-lasting fever
  • Drainage, redness or pain at the incision site
  • Fainting or falling. Either of these may signal changes in brain function.
