Renal Vein Thrombosis After Open Repair of Abdominal Aortic Aneurysm Successfully Treated by Direct Oral Anticoagulants

Abstract

Introduction:

Venous thromboembolism (VTE) of the lower extremities frequently occurs after surgery. It is unknown whether the complication of renal vein thrombosis (RVT) develops after an open repair (OR) for abdominal aortic aneurysm (AAA). Furthermore, anticoagulation therapy with apixaban, a direct oral anticoagulant (DOAC), has not been described as treatment for RVT in such cases.

Case:

A 64-year-old man underwent OR for AAA. Postoperative computed tomography revealed RVT in the left renal vein. Apixaban (5 mg twice a day) therapy was initiated. Six months later, we discontinued anticoagulation therapy and observed no recurrence. Following OR, our patient developed RVT for which DOACs were very useful.

Conclusion:

Thus, RVT can manifest as VTE after OR and direct anticoagulants can be considered as a therapeutic option.
