Hemolytic anaemia due to graft kinking progression and aortic stenosis exacerbation after aortic arch replacement: A case report.

ABSTRACT:

Introduction

Hemolytic anaemia from graft kinking is a rare complication after aortic surgery, typically treated by graft replacement. This case highlights hemolytic anaemia caused by the interaction of aortic stenosis and a kinked graft, successfully managed with transcatheter aortic valve replacement (TAVR).

Presentation of case

A 75-year-old male developed hemolytic anaemia 2 years after total aortic arch replacement for a saccular aneurysm, with a worsening graft kink and aortic stenosis. Phase-contrast MRI confirmed abnormal blood flow at the kink. Due to his frail condition from prostate cancer, TAVR was performed, resolving the anaemia.

Discussion

Factors contributing to graft kinking include intraoperative graft length determination, natural aortic elongation
