[Proximal Aorta Reconstruction for Type A Aortic Dissection Patients without Intimal Tear in Aortic Arch: the Early
Objective:
To evaluate the early and mid-outcomes of proximal aorta reconstruction for type A aortic dissection (AAD) patients without intimal tear in aortic arch, and assess the safety and efficacy of this surgical strategy.
Methods:
From January 2010 to February 2013, there were 23 AAD patients without intimal tear in the aortic arch received proximal aorta reconstruction surgery. Clinical data of these patients were analyzed retrospectively, the mean age was (48.04 ± 12.37) years old (21-73 yr.). Twelve cases were acute aortic dissection, the others were chronic dissection. Bentall surgery was performed for 13 cases, Cabrol surgery for 2 cases, Wheat surgery for 1 case, ascending aorta replacement and aortic valve repair was employed for 1 patient, simple ascending aorta replacement for 6 cases. The patients received follow-up every 3 to 6 months after the surgery.
Results:
The duration of CPB time was (182.83 ± 36.98) min, cardiac arrest time was (111.87 ± 18.82) min, circulatory arrest time was (24.22 ± 6.38) min. The complications were lung infection (4 cases, 17.4%), tracheotomy (2 cases), peritoneal dialysis (1 case), 2 cases suffered transient neurological dysfunction. None stroke, paralysis, and permanent neurological dysfunction occurred. All the patients were discharged. Mean time of follow-up was (38.35 ± 11.95) months (18-56 months). All patients were alive and return to normal life, the proportion of false lumen closure was 65.22% (15 cases). None patients need secondary surgery.
Conclusion:
Proximal aorta reconstruction is safe and effective for AAD patient without intimal tear in aortic arch, the operation strategy can be used individually.
