Infected Abdominal Aortic Aneurysm Presenting with Sudden Appearance: Diagnostic Importance of Serial Computed Tomography

Mycotic Aneurysms in the Abdominal Aorta and Iliac Arteries: CT‐based Grading and Correlation with Surgical Outcomes

“…Nevertheless, traditional surgical excision of mycotic aneurysms with distal revascularization remains the gold standard and should be attempted except in high-risk patients [35]. Sequential CT studies performed in our patients revealed evidence of disease progression, consistent with previous studies showing the progression and enlargement of mycotic aneurysms in serial CT scans [14,22,[30][31][32]. Therefore, urgent surgery might be necessary for most patients to stop the ongoing course and optimize patient outcomes.…”

“…The affected arterial segment was specifically evaluated to distinguish whether the arterial wall was intact or not. Saccular outpouching was defined as the presence of arterial wall destruction with formation of an eccentric blind sac that is contiguous with the arterial lumen [13,[21][22][23]. Associated findings were also evaluated, including psoas muscle abscess [6,14,24], vertebral body destruction [10,13,14,24], arteriovenous fistula [25][26][27][28], massive perianeurysmal hematoma, and active extravasation [13,29].…”
