“…While the experience of others [9,16] with peripheral injections has been favorable, four of our five inadequate examinations were carried out in this manner, and two minor extravasations occurred. These results may also reflect our initial inexperience with digital angiography in addition to occasional early unreliability of the prototype equipment and difficulty in avoiding motion artefacts.…”

Intravenous digital subtraction angiography (IVDSA) in children

1984

Forty-one intravenous digital subtraction angiographic (IVDSA) studies were performed in 39 patients aged 4 weeks to 19 years (mean: 9.4 years) in order to evaluate the heart, great vessels and palliative shunts. Contrast agents were injected via antecubital vein cannulation in 14 examinations. In the remaining 27, injections were made through centrally-placed catheters inserted via right antecubital or femoral veins. All but one of the centrally-injected procedures resulted in technically satisfactory images. Four of the peripherally-injected IVDSA studies were unsatisfactory or of limited value due to motion artefacts, insufficient contrast, equipment failure or perivenous extravasations. Systemic-pulmonary shunt lesions were difficult to image, but IVDSA of the aorta and pulmonary arteries provided consistently useful information.

Pediatric digital subtraction angiography: intraarterial and intracardiac applications

et al. 1986

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.

“…Digital techniques are becoming well established as costeffective for vascular imaging in neuroradiology [1,2]. Pediatric application of this technology is also under development [3]. Futhermore, there has been increasing use of more efficient, less invasive methods of evaluating pediatric spine problems through newer-generation computed tomography (CT) , including scanned-projection radiography, in an attempt to achieve the high contrast resolution of film-screen myelography [4 , 5].…”
