B. Zeevi et al., PERCUTANEOUS CLOSURE OF SMALL PATENT DUCTUS-ARTERIOSUS - COMPARISON OF RASHKIND DOUBLE-UMBRELLA DEVICE AND OCCLUDING SPRING COILS, Catheterization and cardiovascular diagnosis, 39(1), 1996, pp. 44-48
We compared our current practice of closing small patent ductus arteri
osus (PDA) with cells with our previous experience of using double-umb
rellas. Twelve patients underwent percutaneous closure of a small PDA
with a coil. Selection criteria were a minimal diameter of less than o
r equal to 2.5 mm and angiographic type A or E. The 12 most recent, no
n-consecutive patients who had undergone double-umbrella device closur
e of a PDA and would presently be considered suitable candidates for s
pring coil occlusion were retrospectively reviewed. The two groups wer
e compared with regard to complications and immediate and midterm resu
lts. Eleven of the 12 attempted PDA occlusions using spring coils were
successful. The mean follow-up period was 5.8 +/- 4.6 months. Color-D
oppler echocardiograms have shown no residual leaks, no turbulence in
the descending aorta, and no left pulmonary artery stenosis. All 12 at
tempted double-umbrella device placements were successful. The mean fo
llow-up period was 16.2 +/- 5.8 months. Color-Doppler echocardiograms
have shown trivial residual leaks in four patients and mild turbulent
flow in the left pulmonary artery In one patient. There was no signifi
cant difference between the two groups in demographic and hemodynamic
data. Although the mean follow-up time was significantly longer in the
patients who underwent double-umbrella closure, there was significant
ly more color-Doppler echocardiographic evidence of residual flow (P <
0.03). Small PDA closure with coils is effective, resulting in less r
esidual leaks compared with the double-umbrella device. (C) 1996 Wiley
