Endovascular Therapy for Isolated Brachiocephalic Pseudoaneurysm.

In this study, we present a successful endovascular therapy using a small-diameter stent graft for a 73-year-old man who developed asymptomatic pseudoaneurysm of the brachiocephalic artery. An 8F sheath was placed in the brachial artery, and a stiff guidewire was advanced to the descending aorta. The stent graft was delivered to the brachiocephalic artery via the brachial approach. After the initial dilatation, the stent graft was post-dilated to maximum diameter. Final digital subtraction angiography confirmed no endoleak. We believed that endovascular for a brachiocephalic pseudoaneurysm using a small-diameter stent graft might be a minimally invasive and simple method useful in clinical practice.
