Cerebral aneurysm

  1. 1. CEREBRAL ANEURYSM
  2. 2. • An aneurysm is a localized or diffuse dilation of an artery with a diameter at least 50% greater than the normal size of the artery
  3. 3. TYPES • TRUE ANEURYSM • FALSE ANEURYSM According to morphology • Fusiform • Saccular • Dissecting
  4. 4. Saccular • rounded berrylike outpouchings that arise from arterial bifurcation points, most commonly in the circle of Willis. • dilatations of a vascular lumen caused by weakness of all vessel wall layers
  5. 5. • AN ELONGATED SPINDLE-SHAPED DILATION OF AN ARTERY • roughly cylindrical and affects the entire circumference of the
  6. 6. DISSECTING ANEURYSM • Pseudoaneurysm • should be used for encapsulated, cavitated, paravascular hematomas that communicate with the arterial lumen MAY ARISE SPONTANEOUSLY TRAUMA
  7. 7. LOCATION • A common location of cerebral aneurysms is on the arteries at the base of the brain, known as the Circle of Willis. • Approximately 85% of cerebral aneurysms develop in the anterior part of the Circle of Willis,
  8. 8. • Weakness in blood vessel wall • Atherosclerosis • Hypertension • Severe trauma • Weakness in blood vessel wall. • smoking • Alcohol
  9. 9. • NO EARLY SIGNS (some) • Sudden headache • Nausea and Vomiting • Vision impairment • Loss of Consciousness • Nuchal rigidity • Seizures • Dysphagia • Pupillary changes
  10. 10. DIAGNOSIS • CT SCAN • MRI SCANNING • CT ANGIOGRAPHY

  13. 13. FUSIFORM ANEURYSM AT THE BRAIN
  14. 14. MANAGEMENT • SURGICAL MANAGEMENT The goal is to eliminate blood flow into the aneurysm ENDOVASCULAR ANEURYSM REPAIR CRANIOTOMY + REPAIR
  15. 15. • Medical Therapy smoking cessation and blood pressure control
  16. 16. • Surgical Clipping a V-shaped, silver clip to the neck of an internal carotid artery aneurysm. A small metal clip (usually made from titanium) is then applied to the neck (base) of the aneurysm
  17. 17. • Endovascular Coiling Guglielmi detachable coils, known as GDCs, are soft wire spirals originally made out of platinum These coils are deployed (released) into an aneurysm via a microcatheter that is inserted through the femoral artery of the leg and carefully advanced into the brain.
  18. 18. • The microcatheter is selectively advanced into the aneurysm itself, and the microcoils are released in a sequential manner • Once the coils are released into the aneurysm, the blood flow pattern within the aneurysm is altered, and the slow or sluggish remaining blood flow leads to a thrombosis (clot) of the aneurysm. • thrombosed aneurysm resists the entry of liquid blood, providing a seal in a manner similar to a clip. Endovascular coiling is an attract
