Systemic inflammatory response and delayed thrombocytopenia following endovascular aneurysm repair for abdominal aortic aneurysm

Abstract

Postimplantation syndrome following endovascular aneurysm repair (EVAR) is a known entity which presents within the 1st week of EVAR. The symptoms include fever, leukocytosis, and elevated C-reactive protein. Although the pathogenesis is unknown, it resolves within a 5 days. This case report involves elaborating on delayed onset inflammatory response in the 3rd week following EVAR when the patient developed thrombocytopenia which went as low as 55,000/μL. It resolved gradually with supportive measures and systemic steroids.
