Figure 3 Imaging data of single microcatheter embolization of anterior communicating aneurysm. A: The top of the anterior communicating aneurysm was accompanied by a subaneurysm (less than 1mm), which was on the same long axis as the mother aneurysm (arrow); B-D: Single microcatheter embolization of the aneurysm, without deliberately treating the subaneurysm, after dense embolization, the aneurysm did not develop, and bilateral A2 was unobstructed (arrows).
