Flow diverter-coil technique for endovascular treatment of complex wide neck brain aneurysms, Technical point

Treatment of complex wide neck brain aneurysms is a challenging era in neurosurgery. Both surgical and endovascular therapies are considered for treatment of them. In endovascular, there are different ways such as trapping, coiling, stent and balloon assisted coiling. In this study, we use flow-diverter devices to create new vascular lumen and then coiling the aneurysm sac for three patients.

We describe three cases with complex cerebral aneurysm who were treated successfully by flow diverter-coil technique and point to technical nuances.

In our patients, wide neck aneurysms, two in distal part of ICA (internal carotid artery) and other in basilar tip. We use flow-diverter-coil technique successfully. On the follow-up, aneurysms are treated completely without any complications.

We think flow diverter devices adjunct to coiling is a useful way for the treatment of complex wide neck cerebral aneurysms.
