ABSTRACT
AIM: to describe our experience with a series of 18 patients with pericallosal artery aneurysms, in whom endovascular coil insertion was attempted. METHOD: the CT and angiographic appearances, coiling techniques and patient outcomes are discussed. RESULTS: we encountered a higher than expected level of technical difficulty and procedure related complication than when coiling aneurysms in more common locations. In particular the distal position of the aneurysms lead to poorer control over the microcatheter position. Procedure related rupture occurred in three cases. Coiling was not possible in one case only. An association between an angulated bifurcation of the anterior cerebral artery and a sidewall aneurysm configuration was noted. CONCLUSION: despite the technical difficulties and high procedure related rupture rate, coiling of pericallosal aneurysms is feasible and has good outcome.

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.
