Initial experience with a new soft stretch-resistant coil

J Neuroradiol. 2004 Dec;31(5):409-12. doi: 10.1016/s0150-9861(04)97026-5.


The UltiPaq very soft, stretch-resistant coil is a useful new addition to the coil range available to neurointerventionists. Its highly compliant character makes it very suitable for small, ruptured aneurysms, which can easily rerupture during coiling, and for packing the necks of larger aneurysms. It has the advantage of a rapid detachment and does not leave any tail in the parent vessel. The high density of packing achieved in these cases should result in good long-term results, but further follow up is awaited.
