Semiquantitative assessment of lower limb atherosclerosis from routine angiographic images.
In the present report a score system is introduced with the aim of analysing routine angiographic images. The system consists of a vectorial score, which codes the pattern of occlusions, stenoses and plaques, and of an additive score describing the severity of the lesions visualised. The technique is suitable for computerised data analysis.

Prophylactic endovascular radiotherapy to prevent intimal hyperplasia after stent implantation in femoropopliteal arteries.
PURPOSE: Recurrent stenosis or occlusion by intimal hyperplasia occurs in up to 40% of patients with tantalum stent implantations in femoropopliteal arteries and greatly restricts their usefulness. We evaluated the effect of prophylactic endovascular radiotherapy on stenosed/occluded stents. METHODS: We investigated prophylactic endovascular radiotherapy with a surface dose of 12 Gy using an iridium 192 source as a means to reduce or eliminate recurrent stenosis in 4 patients with stenosed/occluded stents, 6-8 months after the original implantation. Confirmatory diagnostic atherectomy, PTA or laser recanalization and endovascular radiotherapy were performed. RESULTS: None of the four has developed recurrent obstruction within 23 to 30 months after this treatment, which up to now shows no short-term or long-term complications. CONCLUSION: We conclude that this limited experience is promising enough to warrant further study.
