Endovascular treatment of irregular and complicated intracranial aneurysms with coils using double microcatheter technique.

Embolisation of irregular and complicated aneurysms is a great challenge for neuroradiologists. To overcome possible complications of endovascular treatment of these type of aneurysms, methods such as intracranial stents, balloon remodelling, and the double microcatheter technique have been developed. The aim of the study was to report our preliminary experience with endovascular treatment of irregular and complicated intracranial aneurysm with coils using double microcatheter technique, and evaluation of its feasibility and clinical advantages. In this retrospective study, 37 cases diagnosed with irregular and complicated intracranial aneurysms and treated using double microcatheter method from July, 2013 to May, 2015, were followed up for six months after discharge. All the aneurysms were successfully embolized using the double microcatheter technique. Immediate post-embolization angiography showed no residual contrast filling in 35 cases, and residual filling in 2 cases. At discharge, according to the modified Rankin Scale score, all the patients recovered without any complications or death. A follow-up of 24 cases with digital subtraction angiography for 6 months revealed no recanalization. In conclusion, the double microcatheter technique for irregular intracranial aneurysms is effective and simple with few complications.
