Mycotic Aneurysms

A mycotic aneurysm is a bulging or ballooning in the wall of an artery due to an infection. Unlike the name suggests, it is not caused by fungi but typically by bacteria. This condition is serious and requires medical attention because the infected artery can weaken and potentially burst, leading to life-threatening bleeding.

Types of Mycotic Aneurysms

  1. Abdominal Aortic Aneurysm: Occurs in the abdominal aorta.
  2. Thoracic Aortic Aneurysm: Found in the upper part of the aorta.
  3. Peripheral Aneurysm: Affects arteries in the limbs.
  4. Cerebral Aneurysm: Located in the arteries of the brain.
  5. Visceral Aneurysm: Involves arteries supplying organs like the intestines and kidneys.
  6. Popliteal Aneurysm: Found in the artery behind the knee.
  7. Femoral Aneurysm: Occurs in the thigh artery.
  8. Carotid Aneurysm: Located in the neck artery.
  9. Iliac Aneurysm: In the pelvic arteries.
  10. Coronary Aneurysm: Affects the heart arteries.
