对60例下肢缺血性溃疡患者进行了动脉内注射放射性微球的外周血管灌注研究。病变和邻近区域的点计数用于定性和定量病变的相对充血。此时此相对充血溃疡愈合。在没有这种程度充血的患者中，只有大约10%的患者最终在没有手术干预的情况下治愈了溃疡。溃疡床相对充血的评估是“缺血性”溃疡愈合潜力的有用、客观、预后指标。
Peripheral vascular perfusion studies utilizing intra-arterial injections of radioactive microspheres were performed on 60 patients who had ischemic ulcers of the lower extremity. Point counting over the lesion and adjacent areas was utilized to qualitate and quantitate the relative hyperemia of the lesion. When this this relative hyperemia ulcers healed. In those without this degree of hyperemia only approximately 10% eventually had their ulcers healed without surgical intervention. Assessment of relative hyperemia of the ulcer bed is a useful, objective, prognostic indicator of the healing potential of an "ischemic" ulcer.
