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.

    ABSTRACT: This study was performed to evaluate the outcome of percutaneous revascularization in "edge restenoses" developing after radioactive stent implantation in de novo and in-stent lesions. Twenty-one consecutive patients undergoing target lesion revascularization (TLR) at any follow-up after phosphorus-32 radioactive stent implantation were included in this study. We assessed the incidence of death, myocardial infarction, repeated TLR and recurrent angina over the following 18 months. After 6 months, TLR rate was 28.6%, and no stent thromboses, deaths or Q-wave myocardial infarctions occurred. Among the patients with TLR there were significantly more subjects who had received a radioactive stent in a previous in-stent restenosis (66.7% vs. 0% in patients without second restenosis; P <0.001), or who had received two radioactive stents (83.3% vs. 33.3%; P = 0.038). After 18 months, TLR rate was 33.3%, and two patients (9.5%) had died. Restenosis after intravascular radiotherapy can be safely treated by percutaneous interventional techniques, yielding an acceptable clinical result within 18 months.

    ABSTRACT: The incidence of late major adverse cardiac events (MACE) after coronary brachytherapy is higher than in controls. Because expansive remodeling has been shown to correlate with poor clinical outcome after vascular interventions, we studied adventitial changes after intravascular irradiation in a rabbit model. Twenty normolipidemic rabbits underwent balloon injury in both external iliac arteries. One artery was assigned for subsequent irradiation with a 90Y source (15 Gy or 30 Gy at 0.5 mm in the vessel wall). After four weeks morphometric measurements were made and cell density and collagen amount determined. Staining for Ki67 identified proliferating cells; apoptotic cells were identified by TUNEL staining. Proliferative and apoptotic indices were calculated as the number of respective positive cells/total cell count x100. The neointimal area decreased to 0.27 +/- 0.3 mm2 after irradiation compared with 0.55 +/- 0.2 mm2 in controls (p=0.007), whereas adventitial area increased from 0.62 +/- 0.3 mm2 to 0.87 +/- 0.3 mm2 (p=0.02). Irradiation reduced both the proliferative (0.95 +/- 2.6 vs. 3.73 +/- 4.7, p=0.026) and apoptotic (0.006 +/- 0.02 vs. 0.107 +/- 0.2, p=0.03) indices in the neointima, but not in the other arterial-wall layers. Collagen amount and arterial remodeling did not differ between the groups. There was no difference between 15 and 30 Gy in any of the parameters, although adventitial thickening was more pronounced in the high-dose group. In normolipidemic rabbits, intravascular beta-irradiation after balloon angioplasty is associated with an increase in neoadventitia and a reduction of neointima. It is conceivable that this phenomenon may contribute to the increased incidence of late MACE after vascular brachytherapy.
