Summary
Infected internal iliac artery aneurysms are rare but can cause serious complications. Prompt diagnosis and surgical intervention, like bypass grafting, are crucial for patient recovery.
Area of Science:
- Vascular Surgery
- Infectious Diseases
- Abdominal Surgery
Background:
- Internal iliac artery aneurysms (IIAAs) are uncommon, with diverse etiologies including atherosclerosis, congenital factors, trauma, pregnancy, and infection.
- Infected IIAAs present a diagnostic and therapeutic challenge due to their rarity and potential for catastrophic rupture.
Observation:
- A 56-year-old male presented with acute symptoms including a swollen, painful left lower limb, limb weakness, fever, and an acute abdomen.
- Emergency laparotomy revealed a colon perforation and a ruptured left internal iliac artery aneurysm.
Findings:
- The ruptured aneurysm was infected, with cultures identifying Staphylococcus aureus and Pseudomonas aeruginosa.
- The patient underwent extra-anatomic cross-femoral bypass grafting to restore blood flow to the left lower extremity.
Implications:
- This case highlights the importance of considering infected IIAAs in patients with relevant symptoms, even if rare.
- Successful management involved prompt surgical repair and broad-spectrum antibiotics, leading to patient recovery with improved limb function.
