Endovascular Therapy for Isolated Brachiocephalic Pseudoaneurysm

Area of Science:

• Vascular Surgery
• Endovascular Interventions
• Aortic Aneurysm Treatment

Background:

• Pseudoaneurysms of the brachiocephalic artery are rare but can pose significant risks.
• Traditional surgical repair can be invasive with associated morbidity.
• Endovascular techniques offer a less invasive alternative for complex vascular lesions.

Purpose of the Study:

• To present a case of successful endovascular therapy for a brachiocephalic artery pseudoaneurysm.
• To evaluate the feasibility and efficacy of using a small-diameter stent graft for this condition.
• To highlight a minimally invasive and simple clinical approach.

Main Methods:

• A 73-year-old male patient with an asymptomatic brachiocephalic artery pseudoaneurysm was treated.
• An 8F sheath was inserted via the brachial artery for access.
• A small-diameter stent graft was delivered and deployed in the brachiocephalic artery through the brachial approach.
• Post-deployment dilatation and angiography were performed.

Main Results:

• Successful stent graft deployment and sealing of the pseudoaneurysm.
• No evidence of endoleak was detected on final digital subtraction angiography.
• The procedure was technically successful, achieving the therapeutic goal.

Conclusions:

• Endovascular therapy using a small-diameter stent graft is a viable and effective treatment for brachiocephalic artery pseudoaneurysms.
• This method offers a minimally invasive and potentially simpler alternative to open surgery.
• The technique shows promise for routine clinical application in managing such vascular pathologies.
