Periaortic Abscess following DeBakey Type-1 Aortic Dissection Repair with Dacron Graft—Early Diagnosis and Management

Abstract EN

A 71-year-old male with history of DeBakey type-1 aortic dissection and repair with dacron graft three months prior to presentation was brought to the emergency room with complaints of high-grade fevers, chills, and shortness of breath.

Chest X-ray revealed right lower lobe infiltrates and widened superior mediastinum.

A follow-up CT chest with contrast showed fluid collection around the aortic graft.

He was started on intravenous broad-spectrum antibiotics, and a TEE was done for further evaluation of periaortic fluid collection which showed findings to suggest periaortic abscess.

The patient underwent surgical drainage of the abscess and was found to have an abscess around the surgical aortic graft which was drained followed by two weeks of antibiotic treatment.

The patient was discharged to a rehabilitation facility and remained asymptomatic at three-month follow-up appointment.

Type-1 aortic dissection is a medical emergency requiring acute surgical intervention, and despite significant advancements in diagnosis and management, the immediate and long-term complications remain high leading to increased risk of mortality.

Our patient developed spontaneous periaortic abscess three months postoperatively requiring intensive antibiotic therapy along with surgical drainage.

Our case emphasizes the importance of early diagnosis and management of late complications of periaortic abscess in patients with aortic dissection repair.
