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.<br> <span style="color:#0000ff;"><strong><em>Methods</em></strong><em>:</em></span> We describe three cases with complex cerebral aneurysm who were treated successfully by flow diverter-coil technique and point to technical nuances.<br> <span style="color:#0000ff;"><strong><em>Results</em></strong><em>:</em></span> 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.<br> <span style="color:#0000ff;"><strong><em>Conclusion</em></strong><em>:</em></span> We think flow diverter devices adjunct to coiling is a useful way for the treatment of complex wide neck cerebral aneurysms.</span></span> <h3></h3> complex brain aneurysms, Flow diverters, coil, Treatment 350 355 http://caspjim.com/browse.php?a_code=A-10-1666-1&slc_lang=en&sid=1 Mohammad Ghorbani mohghorbani@gmail.com 100319475328460029417 100319475328460029417 No Neuroendovascular Division, Firouzgar Hospital, Iran University of Medical Sciences (IUMS), Tehran, Iran Ebrahim Hejazian sehbums@yahoo.com 100319475328460029418 100319475328460029418 Yes Neuroendovascular Division, Ayatollah Rouhani Hospital, Babol University of Medical Sciences , Babol, Iran Eshagh Bahrami bahrami_eses@yahoo.com 100319475328460029419 100319475328460029419 No Department of neurosurgery, Rasool-e-Akram Hospital, Iran University of Medical Sciences, Tehran, Iran Abolghasem Mortazavi sgmortazavi@gmail.com 100319475328460029420 100319475328460029420 No Division of Vascular and Endovascular Neurosurgery, Sina Hospital, Tehran University of Medical Sciences, Tehran, Iran Reza Bahrami Rbahrami1400@gmail.com 100319475328460029421 100319475328460029421 No Department of Neurosurgery, Tabriz University of Medical Sciences, Tabriz, Iran Nazila Farnoush nazilafarnoush@gmail.com 100319475328460029422 100319475328460029422 No Department of Surgery, Babol University of Medical Sciences, Babol, Iran
