title: Endovascular treatment of ruptured sausage-shaped intracranial aneurysms with the "interlacing ball" technique.
abstract: We applied the "interlacing ball" technique to 18 ruptured sausage-shaped intracranial aneurysms (SSIA) with Hunt and Hess Grades I to III in 18 patients. Coils were joined to form the first three-dimensional ball-like structure at the dome of the aneurysm. A segment of the last coil was purposely left out of the first ball so that it could be joined with the next coil used to form a second "ball". This second ball was woven into the neck portion in a net-like fashion to prevent coil protrusion into the parent artery. An immediate post-procedural angiogram showed complete occlusion in 16 aneurysms (88.9%) and near-complete occlusion in two aneurysms with no complications. Sixteen patients were discharged with a Glasgow Outcome Scale (GOS) score of 5, and two with a GOS score of 4. One patient developed an enlarging aneurysm neck as visualized on an angiogram, while 17 aneurysms (94.4%) demonstrated no recurrence, within 3 months to 37 months of follow-up. We report that this technique is useful for the successful embolization of SSIA.
