Abstract

Aortic coarctation is a correctable hypertensive disease. For safety reasons and due to the invasiveness of surgical techniques, percutaneous interventions have become drastically more popular in recent times. In elderly patients with aortic coarctation who are at risk of an aortic wall aneurysm and rupture, covered stents are preferred but in younger patients, bare metal stenting may be sufficient for long-term safety. Herein we present a 47-year-old typical aortic coarctation patient who was successfully treated with a bare metal stent.

  Fig. 1 Pre- and post-procedural CT angiographic findings. A: pre-procedural CT angiography showing severe coarctation of descending aorta just below the left main pulmonary artery level (transparent arrow). Note vigorous collateral blood flow of anterior and posterior trunk (white arrows). B: post-procedural CT angiography showed increased isthmus diameter from 8 to 16 mm (transparent arrow). Diminished collateral blood flow was also observed (white arrows).

  Fig. 2 Invasive angiographic images of pre- and post-stenting. A: thoracic aortography showed the coarctation segment of 8 mm in diameter and 40 mm in length (arrowheads). B: successful deployment of bare metal stent using a 22×50 mm self-expandable nitinol stent showing correct device position without any immediate dissection or perforation (arrowheads).

  Fig. 3 Bare metal stent, pre-mounting state. Hercules vascular stent, S&G, made out of shape memory nitinol with a semi-opencell structure and reconstrainable design. This bare metal stent, which is manufactured in Korea, is available for a diameter of 8 to 22 mm and length of 40 to 120 mm.
