Aortic dissection by bhanu incredible

  1. 1. AORTIC DISSECTION By bhanu prakash 10DE1R0011
  2. 2. AORTA : the aorta is the main blood vessel that carries blood from the heart to the rest of the body.
  3. 3. • An aortic dissection is a tear in the wall of the aorta that results in forceful blood flow through the middle layer of the aortic wall that can lead to weakening and separation of the aortic wall.
  4. 4. Signs and symptoms • • • • • • • • Sudden pain in the back, chest, neck or jaw High blood pressure Myocardial infarction Pleural effusion Aortic insufficiency Sweating Shortness of breath Loss of consciousness (fainting)
  5. 5. RISK FACTORS:  MARFAN SYNDROME  AORTIC DILATATION  HYPERTENSION  COARCTATION OF THE AORTA  BICUSPID AORTIC VALVE  PREGNANCY  scoliosis
  6. 6. PATHOPHYSIOLOGY:
  7. 7. Diagnosis:         ECG BLOOD TESTS CHEST X-RAY CT MRI TTE TEE AORTOGRAPHY
  8. 8. CLASSIFICATION • Stanford Classification   Type A -involves ascending aorta Type B –involves descending aorta • DeBakey Classification    Type I –ascending, arch & descending aorta Type II –ascending only Type III –descending only
  9. 9. Medication : o Beta blockers : esmolol propranolol labetalol o Calcium channel blockers: verapamil diltiazem
  10. 10. Surgical: Some methods of repair are: • Replacement of the damaged section with a tube graft (often made of dacron) when there is no damage to the aortic valve. • Bentall procedure — Replacement of the damaged section of aorta and replacement of the aortic valve. • David procedure — Replacement of the damaged section of aorta and reimplantation of the aortic valve.
  11. 11. Bentall procedure
  12. 12. David Procedure
  13. 13. Conclusions • Aortic dissection is a life-threatening condition that must be diagnosed and treated without delay. • Dissections involving the beginning portion of the aorta (type A) are treated with emergency surgery and those involving the descending aorta (type B) are usually treated with medications.
