The value of isotope angiography in the diagnosis and management of vascular disease

We performed 182 isotope angiograms on 173 patients over a three year period. We have reviewed our results and evaluated the role of isotope angiography in vascular surgery by comparing it with contrast angiography, ultrasound imaging, clinical and operative findings and subsequent course of the patient. Isotope angiography was particularly useful in the investigation of abdominal aortic aneurysms; 58 aneurysms being found following 92 investigations. There were no false positive results but four false negative results were obtained. Following vascular reconstruction 40 isotope angiograms were carried out; the correct diagnosis was made in 98%. This is now our investigation of choice in these patients. Isotope angiography was also useful in the investigation of peripheral vascular disease especially in those patients where a more invasive technique might be contraindicated (author)
