abstract = {The embolization technique can have significant impact on
the success of endovascular embolization.To evaluate the
feasibility, embolization characteristics, and embolization
extent with a newly developed extra-small micro-balloon
catheter in an in vivo and in an in vitro embolization model
in comparison with standard microcatheter
embolizations.Twenty-eight embolization procedures were
performed in the porcine rete mirabile (RM) and in an in
vitro embolization model, using either an extra-small
(distal outer diameter 1.6 F) dual-lumen micro-balloon
catheter or a standard microcatheter. Precipitating
hydrophobic injectable liquid (PHIL) was used as embolic
agent. Procedure times, number of injections, required
volume of embolic agent, and embolization extent (percentage
of embolized RM in postinterventional X-ray scans or number
of filled sections of the in vitro model) were assessed.
Histopathological analyses were performed.Total procedure
time was significantly shorter (in vivo: 123 s vs 615 s
(medians), P=0.001; in vitro: 180 s vs 496 s (medians),
P=0.001), number of reflux events was significantly lower
(in vivo: 0 vs 9 (medians), P=0.001; in vitro: 0 vs 3
(medians), P=0.001), and embolization extent was
significantly higher (in vivo: $96.9\%$ vs $65.6\%$
(medians), P=0.011; in vitro: 26 vs 18 filled sections
(medians); P=0.041) for the micro-balloon catheter groups.
There was antegrade movement of the PHIL cast after balloon
deflation in one in vitro embolization procedure and
spontaneous balloon deflation with subsequent reflux in one
in vivo embolization procedure.Extra-small dual-lumen
micro-balloon catheters can improve endovascular
embolization in comparison with standard microcatheter
embolization.},
