Pediatric digital subtraction angiography: intraarterial and intracardiac applications

Abstract

Intraarterial digital subtraction angiography (IA-DSA) was performed in 80 pediatric patients. Forty-four underwent arterial injections with digital filming techniques. Of the 130 injections, DSA imaging was good or excellent in 121, often allowing resolution of vessels 1 mm in size. Thirty-six of the 80 patients underwent cardiac evaluation with intra-cardiac injections. Improved contrast resolution with IA-DSA allowed the use of smaller catheters (3-4F) and smaller amounts of contrast material. Immediate availability of subtracted images (no film processing delay) resulted in shorter total procedure time. Outpatient studies are possible. IA-DSA provides several notable advantages for the pediatric patient.

Imaging Approach to the Diagnosis of Pulmonary Sequestration

“…These modalities can demonstrate the origin, number, course and size of the feeding arteries and draining veins, and they are valuable in the surgical planning (10).…”

The continued value of angiography in planning surgical resection of benign and malignant hepatic tumors in children

“…At this time, however, angiography remains an important diagnostic and therapeutic imaging method. The following criteria for angiographic evaluation are widely accepted: [1] determination of partial hepatectomy, [2] determination of extent of caval involvement when sonography and CT are inconclusive, [3] to determine the patency of the portal vein, [4] for arterial chemotherapy infusion, and [5] for arterial occlusion in infantile hemangioendothelioma [4][5][6][7][8][9][10].…”

Imaging of the Neonate with Congenital Heart Disease

“…Computerized angiography, or digital subtraction angiography, has many indications in the newborn infant, especially in the investigation of the aortic arch, aortopulmonary collateral and pulmonary veins [4,28,50,51]. Because the technique possesses high contrast resolution, excellent images can be obtained with low amounts of contrast material.…”
