A Case of Acute Retrograde Aortic Dissection during TALENT Endovascular Repair of a Thoracic Aortic Aneurysm / 日本心臓血管外科学会雑誌

ABSTRACT

An 83-year-old woman underwent stent graft endovascular repair using a Medtronic TALENT device for a saccular aortic aneurysm in the distal arch. The landing zone which targeted the proximal side was directly distal to the orifice of the left common carotid artery (Z2), and the stent graft was placed at the targeted position. However, a decline in the right radial arterial pressure was observed immediately following this, and a retrograde dissected ascending aorta was observed on a transesophageal echocardiogram. The endovascular surgery was immediately converted to open surgery, and an intimal tear to the lesser curvature of the arch, caused by a bare spring (bare stent) of the proximal stent graft, was observed. Total arch replacement was performed by means of the concomitant use of the placed stent graft. Sometimes a TALENT stent graft exhibits specific movements (e.g. a misaligned opening) on its initial deployment. It is therefore believed that special attention is necessary when placing it in the aortic arch.
