Abstract
Postmortem angiography and histologic analysis of a fatal coronary thrombosis 4 months after implantation of a radioactive stent are described. Histologic findings suggested incomplete re-endothelialization in the segment with the stent. Ionizing radiation may delay re-endothelialization after revascularization, thus maintaining the thrombogenicity of the irradiated vessel segment. Thus, prolonged antiplatelet therapy should be considered after intravascular radiation therapy.
