Background:
A wide-necked aneurysm is defined as the one with a neck greater than 4 mm in diameter. Embolisation of wide-necked aneurysms is a great challenge for neuroradiologists. To overcome possible complications of endovascular treatment of this type of aneurysms, methods like intracranial stents, balloon remodelling, the double microcatheter and the microcatheter protective technique have been developed.
Case Report:
We report a case of embolisation of a 63-year-old woman with a wide-necked aneurysm using the double microcatheter technique. Introduction of the second microcatheter into the aneurysm allowed for crossing two coils and prevented protrusion into the parent vessel, which resulted in successful treatment without postprocedural complications. Both postembolic and follow-up angiography showed complete exclusion of the aneurysm.
Conclusions:
The double microcatheter technique, owing to creation of a stable coil frame across the neck of the aneurysm, is suitable for treatment of aneurysms with an adverse dome-to-neck ratio. This technique is easy to perform for an experienced neuroradiologist.
