How is it diagnosed?

Our team of specialists provides thorough neurological evaluations using the latest diagnostic technology including CT angiography and 3D angiography. Some of the things doctors consider in whether or not to treat an unruptured aneurysm are:

  • Age and health of patient
  • Family history
  • Patient preference
  • Risk of hemorrhage
  • Size and location of aneurysm
  • Surgical and endovascular risks

In almost all cases ruptured aneurysms require urgent medical treatment. Unruptured aneurysms, however, may or may not require treatment. In some cases, doctors may recommend follow-up with serial imaging studies.
