Surgical treatment of cerebral aneurysm

Treatment of these lesions is dependent on whether they have ruptured or not. Ruptured aneurysms (SAH) are a medical emergency and immediate hospital admission is warranted. A CT scan of the head is diagnostic in 99% of cases, although some patients may require further tests like a lumbar puncture to confirm that a rupture has occurred.

Early treatment is aimed at supporting the patient and securing the aneurysm to protect from repeat bleeds.

Treatment can be either through the arteries/veins (endovascular coiling) or through an open operation (craniotomy). The decision on the best mode of treatment is taken after special investigations have been performed and depends:

  • Overall clinical condition of the patient
  • Age and other medical problems
  • Anatomy of the aneurysm
  • Location
