Department of Neurosurgery and Neurotraumatology, in Poznan, with the aim of undergoing endovascular treatment. Digital subtraction angiography in access via the right femoral artery showed an aneurysm in the right internal carotid artery, in the ophthalmic segment, measuring 7.4x4.2 mm, with an unfavourable configuration (the neck measured 3.4 mm) (Figure 1).
(A) Failed attempt of standard coiling with one microcatheter. (B) Simultaneous use of two microcatheters.

Firstly, standard embolisation with one microcatheter was performed (Vasco 10, Balt, Montmorency, France), but protrusion of the loop of the coil into the parent vessel was noticed (Figure 2A). Afterwards, two coils (Target 360 Standard Coils 5x15 Stryker Cork, Ireland) were implanted simultaneously as an initial stable basket-frame for the next coils (Figure 2B).
Postembolic angiogram showing complete aneurysmal occlusion.

Postembolic angiography showed complete exclusion of the aneurysm (Figure 3).
Follow-up angiogram after 6 months since the procedure, showing no recanalization within the aneurysm.
