Background:
Aortic dissection is a medical emergency with high mortality rate despite the recent advances in treatment modalities. Short-term mortality, complication rates, and 1-year survival rates are reported in this study for both type A and type B aortic dissections after respective surgical and medical treatments.

Material and Methods:
A total of 26 patients, both type A (n=15) and type B (n=11) from 2008 through 2013 are retrospectively analyzed for short-term outcomes, such as mortality and complication rates, and also 1-year survival rates. Mann-Whitney U test, Fisher’s exact test, χ2 test and Kaplan-Meier survival analysis were used for statistical analysis.

Result:
Overall short-term mortality rates for type A and type B aortic dissections are 66.7% (20.0% intraprocedural, 46.7% postprocedural) and 27.3% (9.1% intraprocedural, 18.2% postprocedural) respectively. Complication rates are 66.7% (20.0% intraprocedural, 46.7% postprocedural) for type A and 36.4% (9.1% intraprocedural, 27.3% postprocedural) for type B aortic dissection. 1- year survival rate is 33.3% for type A, and 72.7% for type B. There is no statistically significant difference between the mortality, complication rates and 1-year survival rates of type A and type B aortic dissections (P> 0.05).

Conclusion:
The short-term mortality and complication rates of aortic dissection remain considerably high disregard to the type of the dissection or the treatment modality. However, type B has slightly better outcome compared to type A aortic dissections.
