2. OBJECTIVE
The aim of this study is to evaluate the early mortality and morbidities in acute ascending aortic dissection patients treated by aortic root reconstruction techniques.

3. METHODS
This is a retrospective and prospective non randomized study including 30 patients in which aortic valve sparing and root reconstruction was done.

4. METHODS INCLUSION CRITERIA: - Acute Stanford type A aortic dissection
- Left ventricular EF above 30%
EXCLUSION CRITERIA:
- Redo patients
- Stanford type B aortic dissection
- Patients undergoing replacement of ascending aorta plus other cardiac surgeries.
- Patients with rheumatic aortic valve diseases.

5. RESULTS Mean age: 53±12 years Gender distribution: 21 males (70%)
9 females (30%)

6. RESULTS
Aortic valve re-implantation: 19 patients

7. RESULTS One or two sinus replacement plus supra- commisuralconduit:
10 patients
Remodelling technique: 1 patient

8. RESULTS Early mortality 6 (20%) Neurological complications 7(25%)
Renal complications
10 (35.7%)
Respiratory complications
5 (17.9%)
Re-opening for bleeding

9. RESULTS
Early mortality : 2 intra-operative mortalities, due to myocardial failure and massive uncontrollable bleeding. The other 4 patients died during the first 48 hours in I.C.U, 3 of them because of myocardial failure and one because of respiratory failure.
Neurological complications : delayed recovery more than 24 hours in 4 patients and 3 patients with cerebro-vascular stroke one of which suffered permanent hemiplegia .
 Renal complications : Ten patients had renal impairment in the form of elevated creatinine, 3 of them needed one or two sessions of dialysis and resolved completely and only one patient became in need for regular dialysis .

10. RESULTS Post-operative echocardiography Aortic regurge Nil : 21 (75%)
Trivial: 4 (14.3%)
Mild: 3 (10.7%)
Moderate: 0
Severe: 0

11. CONCLUSION:
Our early results show excellent valvular stability without an increased operative risk.
Freedom from anticoagulation and complete resection of diseased tissue represent unquestionable advantages of these techniques.
