Thrombotic occlusion of a drug-eluting stent - is IVUS mandatory.

Abstract

Acute stent thrombosis is a rare but serious complication of stent implantation. Although anecdotal reports suggest that the use of drug-eluting stents (DES) may increase the risk of stent thrombosis, this has not been borne out in randomized, controlled trials. We report a case of acute stent thrombosis following implantation of a DES, with review of the literature. Despite the initial favorable procedural result, the patient developed stent thrombosis 7 days later; intravascular ultrasound (IVUS) demonstrated incomplete deployment of the stent. We recommend the use of IVUS in the management of acute stent thrombosis in order to exclude incomplete stent expansion which may underlie acute th..
