Redo-Bentall surgery for aortic root lesions: a report of case series

To observe the clinical efficacy of Redo-Bentall surgery in the reoperation of aortic root lesions.

A retrospective analysis was performed on 46 patients who underwent Redo-Bentall surgery for aortic root lesions in our department from June 2010 to April 2022. They were 35 males and 11 females, at a mean age of 43.37±12.79 years, in 4.96±6.76 years since the last operation. General clinical data in perioperative period and during follow-up were collected and analyzed. Kaplan-Meier survival analysis was used to compare the survival rates of each etiological group.

There were 9 cases of central end otitis, 12 cases of Behset's disease, and 25 cases of other causes. After operation, 4 cases (8.70%) experienced cardiac arrest, 4 cases (8.70%) renal failure, 2 cases (4.35%) gastrointestinal bleeding, 2 cases (4.35%) new third-degree atrioventricular block and 2 cases (4.35%) permanent pacemaker placement. In perioperative period, 3 cases (6.52%) died in hospital. During a mean follow-up of 5.03±3.27 years after discharge, 5 cases (11.63%) were lost to follow-up, 1 case died (2.33%), 1 case had lacunar infarction (2.33%), and no severe bleeding or embolism complications was observed in the rest patients. The long-term survival rate was significantly lower in the endocarditis group (62.3%) and the Behcet's disease group (70%) than the other etiological groups (80%, P < 0.05).

The application of Redo-Bentall in the reoperation of aortic root lesions is safe and effective, but the survival rate is quite lower in the patients with infective endocarditis and Behcet's disease.
