Subintimal stent implantation for the treatment of a chronic coronary occlusion

Subintimal passages of the guide wire during mechanical recanalization of chronic coronary occlusions are frequent and may result in the inability to reestablish anterograde flow in the distal coronary lumen. By using coronary stents, a conduct through the subintimal pathway can be obtained, allowing long-term restoration of the anterograde blood flow. We report on a case of a long, subintimal vessel reconstruction of a five-year-old coronary occlusion. Under intravascular ultrasound guidance, multiple coronary stents were implanted and good procedural and long-term clinical and angiographic results were achieved.
