Gliederung

Text

Objective: In the endovascular treatment of cerebral aneurysms, navigating a large-bore microcatheter for delivery of a stent can be challenging, especially in wide-necked bifurcation aneurysms. We were able to overcome this difficulty by parallel use of two microwireguidewires through the stent-delivery microcatheter.

Method: From December 2014 to April 2015, we treated 15 patients with wide-necked bifurcation aneurysms. For stent delivery, we use a 300-cm 0.014-inch microguidewire, which placed into the target branch using an exchange technique. A 0.027-inch microcatheter, which was designed for the stent, advanced over the exchange microguidewire. If we had trouble in advancing the microcatheter over the exchange microguidewire, we inserted a regular microguidewire into the microcatheter lumen in a parallel fashion. We also analyzed the mechanism underlying microcatheter positioning failure and the success rate of the 'parallel-wire technique'.

Results: Among the 15 cases, we faced with navigation difficulty in five patients. In those five cases, we could advance the microcatheter successfully by applying the parallel-wire technique. There were no procedure-related complications.

Conclusions: Simply by using another microguidewire together with pre-existing microguidewire in a parallel fashion, the stent-delivery microcatheter can easily navigated into the target location in case of any advancement difficulty.
