title: The use of intravenous digital subtraction angiography in the evaluation of tetralogy of Fallot.
abstract: Sixteen patients with tetralogy of Fallot were studied with intravenous digital subtraction angiography (DSA). Of these, 11 were males and five were females, ranging in age from 26 months to 54 years, with a mean age of 22 years at the time of the initial study. Twenty-two DSA studies were performed in the 16 patients, in seven patients preoperatively, in 12 patients postoperatively, and in three patients both pre- and postoperatively. In the seven patients studied preoperatively, all DSA studies were considered technically adequate as corroborative evidence in the diagnosis of tetralogy of Fallot. All associated cardiac abnormalities were adequately demonstrated. The 16 postoperative studies on 12 patients were performed to evaluate the adequacy of the surgery and/or postoperative complications. These studies were judged as technically satisfactory. The authors utilized intravenous DSA in the pre- and postoperative evaluation of 16 patients with tetralogy of Fallot and found that reliable angiographic information was provided and that this technique may serve as a useful adjunct with other noninvasive and invasive tests in the preoperative and postoperative evaluation of these patients.
