Endovascular treatment of multiple aneurysms complicating Cogan syndrome

Area of Science:

• Vascular Surgery
• Cardiology
• Rheumatology

Background:

• Cogan syndrome (CS) can lead to complex aortic and carotid aneurysms.
• Managing multiple aneurysms in CS presents significant surgical challenges.

Purpose of the Study:

• To evaluate the efficacy of endovascular grafts in treating multiple aneurysms associated with Cogan syndrome.
• To assess the long-term outcomes of endovascular repair in a young patient with CS.

Main Methods:

• A 38-year-old female patient with descending thoracic aorta and right common carotid artery aneurysms due to CS underwent endovascular repair.
• Follow-up included angio CT scans and echo color Doppler assessments.

Main Results:

• Complete exclusion of aneurysms with no endoleak observed at 4-year follow-up.
• Carotid graft remained patent with no restenosis or disease progression in landing zones.
• Successful aneurysm exclusion was confirmed by imaging modalities.

Conclusions:

• Endovascular repair is a viable and effective treatment for multiple aneurysms in Cogan syndrome.
• This approach offers favorable long-term outcomes, especially for patients unfit for open surgery.
• Minimally invasive endovascular repair should be considered for complex aneurysms in young patients at high surgical risk.
