Isolated mycotic hypogastric artery aneurysm

Area of Science:

• Vascular Surgery
• Interventional Radiology
• Infectious Disease

Background:

• Isolated iliac artery aneurysms are uncommon, often co-occurring with aortic aneurysms.
• Hypogastric artery aneurysms (HAAs) represent an exceptionally rare subset of iliac aneurysms.
• Standard treatment for HAAs typically involves exclusion and bypass procedures.

Observation:

• The case involved a patient with a mycotic HAA, indicating an infection within the aneurysm.
• Mycotic aneurysms present unique challenges due to the infectious component.
• Traditional surgical approaches may be complicated by the presence of infection.

Findings:

• Endovascular techniques, specifically coil embolization and exclusion, were utilized for managing the mycotic HAA.
• The endovascular procedure was followed by a successful aortic to external iliac artery bypass using a cadaveric conduit.
• This combined approach effectively addressed the complex mycotic HAA.

Implications:

• Endovascular methods offer innovative solutions for managing rare and complex vascular pathologies like mycotic HAAs.
• This case highlights the potential of hybrid approaches combining endovascular and open surgical techniques.
• Successful treatment of mycotic HAAs can improve patient outcomes and reduce morbidity associated with these rare conditions.
