Abstract:
Saccular mycotic aorto-iliac aneurysms are rare but, when ruptured, they are an important life-threatening condition. We present the case of a 52 years-old male transferred from another hospital and admitted to the emergency room with a ruptured iliac artery aneurysm. He complained of persistent fever and abdominal discomfort that swiftly established as hemorrhagic shock. Image study with computed tomographic angiography revealed a ruptured left common iliac artery saccular aneurysm. The patient was instantaneously and successfully submitted to endoaneurismorraphy of the hypogastric artery, common and external iliac artery ligation and construction of an extra anatomic bypass, right to left femorofemoral bypass. Blood culture revealed a Streptococcus anginosus and the patient received appropriate targeted antibiotics. Post-operative period was uneventful and the patient discharged ten days after admission. He has now eleven months of follow up with no intercurrences. Even though surgical approach carries a relative risk of perioperative morbidity, it is a feasible and durable solution for extreme situations like the one here described.
Insights
Ruptured iliac artery aneurysms are rare but life-threatening. Surgical repair, including bypass, offers a feasible solution for these critical cases, ensuring patient recovery.
Area of Science:
- Vascular Surgery
- Infectious Disease
Background:
- Saccular mycotic aorto-iliac aneurysms are uncommon but pose a significant risk of rupture and mortality.
- Prompt diagnosis and intervention are crucial for managing ruptured aneurysms.
Observation:
- A 52-year-old male presented with fever, abdominal discomfort, and hemorrhagic shock due to a ruptured left common iliac artery saccular aneurysm.
- Computed tomographic angiography confirmed the diagnosis of a ruptured saccular aneurysm.
Findings:
- The patient underwent successful endoaneurismorraphy, iliac artery ligation, and femorofemoral bypass.
- Blood cultures identified Streptococcus anginosus, and targeted antibiotic therapy was initiated.
Implications:
- Surgical intervention, despite potential risks, provides a durable solution for complex ruptured aneurysms.
- This case highlights the successful management of a rare, life-threatening vascular condition.
