Anterior Inferior Cerebellar Artery (AICA) Obstruction

Anterior Inferior Cerebellar Artery (AICA) obstruction is a condition where the blood flow in the AICA is blocked. This artery supplies blood to the cerebellum, which is responsible for coordination and balance. When the artery is obstructed, it can cause significant neurological problems.

Types

  1. Thrombotic AICA Obstruction: Caused by a blood clot forming in the artery.
  2. Embolic AICA Obstruction: Caused by a clot that travels from another part of the body and lodges in the AICA.
  3. Atherosclerotic AICA Obstruction: Caused by plaque buildup in the artery.
  4. Traumatic AICA Obstruction: Resulting from physical injury to the artery.
  5. Infectious AICA Obstruction: Caused by an infection that affects the artery.
  6. Inflammatory AICA Obstruction: Resulting from inflammatory diseases like vasculitis.
  7. Tumor-related AICA Obstruction: Caused by a tumor pressing on the artery.
  8. Congenital AICA Obstruction: Present at birth due to abnormal artery development.
  9. Iatrogenic AICA Obstruction: Resulting from medical procedures.
  10. Spontaneous AICA Obstruction: Occurring without a known cause.
  11. Hypoplastic AICA Obstruction: Due to underdevelopment of the artery.
  12. Hypercoagulable State AICA Obstruction: Due to conditions that make the blood more likely to clot.
  13. Fibromuscular Dysplasia AICA Obstruction: Caused by abnormal growth in the arterial wall.
  14. Dissecting AICA Obstruction: Due to a tear in the artery wall.
  15. Post-surgical AICA Obstruction: Following surgery near the artery.
  16. Radiation-induced AICA Obstruction: From exposure to radiation therapy.
  17. Autoimmune AICA Obstruction: Caused by autoimmune diseases attacking the artery.
  18. Drug-induced AICA Obstruction: From drugs that affect blood clotting.
