Abstract

Introduction: Since its introduction in 1968, the Bentall procedure has been the primary surgical solution for aneurysms of the aortic root. However, many surgeons have reported serious procedural complications such as detachment of coronary ostia and pseudoaneurysm formation at anastomosis sites. Therefore, the Bentall procedure has undergone several modifications to eliminate those complications. Partial or total detachment of the proximal anastomosis is rarely reported.

Presentation of case: We report a total detachment of the proximal anastomosis after a Bentall operation with emphasis on the possible practical mechanisms, which might have led to the development of this very rare complication. The diagnosis was confirmed at a routine follow up examination and urgent surgery was performed. We also report our operative solution and review other possible surgical solutions that might be considered in this setting.

Discussion: The Bentall procedure and its modifications continue to be considered the gold standard for treating aneurysms involving the aortic root. Various modifications can serve as optimal solutions for procedure-related complications.

Conclusion: Surgeons performing the Bentall procedure must be familiar with all existing modifications because they are complementary to the original surgical procedure. In the absence of endocarditis left ventricle outflow tract elongation may be an acceptable surgical solution to deal with total detachment of the proximal anastomosis.

Keywords: Bentall procedure; Case report; Left ventricle outflow tract elongation; Pseudoaneurysm.
