  • Brain aneurysm: A cavernous aneurysm is a common finding that if truly cavernous, indicates that it is located outside of the brain and generally carries a benign prognosis.[healthtap.com]
  • The long term prognosis for treated cases is relatively good, with most complications occurring immediately after the procedure.[jnnp.bmj.com]
  • Because of the dismal prognosis of the malignancy and contraindication of antiaggregative drugs for reasons of a single hemorrhagic metastasis in the right cerebellar hemisphere, the multidisciplinary decision was made to refrain from endovascular treatment[jbsr.be]

  • Although CCFs from ruptured cavernous sinus aneurysms may close spontaneously, as in 2 of our patients with low-flow CCFs, angiography and endovascular closure of the fistula should follow promptly to prevent possible hemorrhage from engorged cortical[ajnr.org]
  • To contain the infection, the body's immune system creates a clot to prevent bacteria or other pathogens from spreading. The clot increases pressure inside the brain . This pressure can damage the brain and may ultimately cause death.[webmd.com]

  • The combination of coils and thrombus forms a plug which prevents blood from going into the aneurysm, and protects the aneurysm from rupture. Depending on the shape of the aneurysm, the coils may have a hard time staying inside.[med.nyu.edu]
