New modification of modified bentall procedure (A single centre experience).

Background And Objectives: Modified Bentall procedure has become a gold standard in the treatment of combined aortic root and aortic valve diseases. Bleeding is an important predictor of morbidity and mortality after the Bentall operation. Our objective was to evaluate the early outcomes of Modified Button-Bentall procedure with cuff technique for aortic root replacement surgery regarding hemostasis.

Methods: A total number of 32 patients who underwent elective Bentall operation from January 2008 to December 2014 were included in the study. In 18 patients (Group I) modified Button-Bentall procedure with formation of cuff was used and in 14 patients (Group II) Modified Button technique without cuff formation was used for aortic root replacement. Data was analyzed using SPSS V16. Chi-square test, Fisher's Exact test and independent sample t-test was used to analyze Qualitative and Quantitative variables.

Results: Three patients in Group II and two patients in group I was in congestive cardiac failure pre-operatively. Out of thirty two patients two patients were having Aortic root dissection one in each group. Total bypass time and cross-clamp time were significantly high in Group I. There was no significant difference regarding duration of inotropic support, ventilation time, ICU stay and hospital stay time in patients of Group I and Group II. But post-op Chest drainage was very high in Group II 1158+451.25 ml versus 488.89+168.27 ml in group I (p-value <0.0001). There was one in hospital death in Group II.

Conclusions: Formation of cuff of remnant of aorta during proximal anastomosis results in significant reduction in post-operative bleeding and was better in hospital outcomes.
