Experiences of cabrol root replacement in management of type A aortic dissection 后印本

摘要: Objective Cabrol procedure was introduced by Professor Cabrol C in 1981, but little information existed regardingthe results of Cabrol technique in aortic dissection(AD). This study explored a 7-year period results of aortic root replacementsin type A aortic dissection employing this procedure. Methods From January 2009 to December 2016, 47 patients with type Aaortic dissection received Cabrol procedure in our hospital. All patients received echocardiography and CT scan of whole aortabefore operation. Cabrol procedure was performed to repair the aortic root. The replacement of right hemi aortic arch or totalaortic arch and a stented frozen elephant trunk implantation might be performed based on the extent of the dissection in theaortic arch. A retrospective analysis was performed to evaluate the effectiveness of this procedure in type A aortic dissection.Results Forty-seven cases were admitted, including 6 cases of simple Cabrol procedure, 13 cases with concomitantreplacement of right hemi aortic arch and 28 cases with concomitant total aortic arch replacement and frozen elephant trunktechnique.The 30-day mortality was 10.6%(5/47). 25.5%(12/47) of patients developed acute renal failure, and 12.8%(6/47)needed continuous renal replacement therapy (CRRT) during hospital time. The median hospital time were 25.5 d, rangingfrom 15 to 128 d.It followed-up from 6 to 36 months. Conclusion The Cabrol procedure is feasible and safe for patients withtype A aortic dissection. The artificial blood vessels are unobstructed.
