Objective: Owing to the limited time since the introduction of the PulseRider (PR), inconsequential or rare complications that clinicians should be aware of remain unreported yet. Here, we report a rare complication of incomplete detachment.
Case Presentation: A 50-year-old male underwent PR-assisted coil embolization for a basilar tip aneurysm. Coiling was completed, and the detachment procedure was performed using a detachment machine; the success signal was observed. The delivery microcatheter was subsequently advanced back up to the proximal markers, and no reapproximation of the proximal markers, which indicates successful detachment, was observed. However, only one of the proximal markers returned to the microcatheter, and incomplete detachment of only one leg was detected. Ultimately, electrical detachment was not possible, and physical separation by tension was achieved.
Conclusion: Our case report presents a rare case of a detachment problem in the PR. The PR could not be detached, although the signal revealed successful detachment. Therefore, careful withdrawal of the delivery wire by checking not only the proximal markers but also the behavior of the entire PR and coil complex is important.
