Complications of intravenous DSA performed for carotid artery disease: a prospective study

JO Aaron, JR Hesselink, R Oot, RL Jones, KR Davis and JM Taveras

One hundred and two patients, who were being evaluated for carotid artery disease, were prospectively studied for complications occurring as a result of intravenous digital subtraction angiography (DSA). We recorded the type, number, and outcome of complications and reviewed the amount of contrast material used, along with the patient's age and medical history for possible correlation with increased complications. There were 55 total complications or side effects involving 37 patients. Central nervous system (CNS) complications included six major- transient and one major-permanent complication. Systemic complications included 20 major-transient and two major-permanent events. The patient's age and the amount of contrast material used did not appear to be significant risk factors. Complications in our series were significantly higher than previous DSA reports and published data on conventional angiography studies. Many of our patients were in a relatively high risk group, including 74 patients who had multisystem disease and 30 who had histories of angina.
