[Value of cardiac scintigraphy using thallium dipyridamole in the preoperative diagnosis of vascular diseases].
The authors assess the value of cardiac scintigraphy using thallium dipyridamidole in the preoperative examination of vascular patients. Data from the literature indicate the real possibility of cardiac complications in major vascular surgery. These complications, which range from simple arrhythmias to lethal myocardial infarctions, have an incidence of 0.5-2% in aortic surgery, 0.6-3% in peripheral revascularisation increasing to 2.6-8.3% in distal revascularisation, although they are less important in carotid surgery. From January 1993 to March 1994 cardiac risk was evaluated in 44 patients due to undergo major vascular surgery using cardiac scintigraphy with thallium dipyridamidole. The test was negative in 14 cases. The presence of one or more redistribution areas was observed in 23 cases, and a fixed zone in 7 cases. In line with the proposals made by Eagle, the authors conclude that it is necessary to restrict the indications for this test to those cases presenting at least two risk factors.
