Abstract

Objectives: Acute aortic dissection is one of the most serious cardiovascular emergencies, especially the Stanford A – De Bakey I one. Beside the conventional approach, hybrid surgery (modified frozen elephant trunk technique) is considered to be an efficient solution for damages in descending aorta. However, it is necessary to conduct a research about the efficacy of this kind of surgery. Subject and method: We have reviewed retrospectively all the cases that had pre-operative diagnosis as Stanford – De Bakey I aortic dissection and were treated by using hybrid surgery from 5/2020 to 9/2020 at Cardiac Care-Surgery department of Cho Ray Hospital. Results: There are 17 patients in the study, 13 males and 4 females, whose average are is 56,5±12,7. The pre-operative left ventricular ejection fraction (EF) is 63±3,9%. The average diameter of ascending aorta is 43,2±1,8 mm and the rate ascending aortic diameter/body surface is 24,14 mm/m2. The clamping time is 118±39 minutes and the time of extracoporeal circulation is 220±30 min. The number of grafts for one patient is one, and the length is 175,7±16 mm. The mortality is 2/17 (11,7%). Conclusion: The hybrid surgery (modified frozen elephant trunk technique) is an effective solution and strongly-recommeneded for the cases of Acute Stanford A- DeBakey I aortic dissection. This approach can be transferred to other cardiac centers in Vietnam.
