“…[ 11 ] PR implants are appropriate and effective for wide-necked aneurysms that need a T-stent or Y-stent[ 5 ] but have less intraluminal metal. [ 4 , 7 , 13 ] Some authors have reported promising midterm results. [ 1 , 2 , 9 ] However, the PR has a more limited range of applications than other conventional stents because both leaflets need to be simultaneously introduced into each daughter vessel.…”

Background: Unlike other conventional neck bridge stents, when using the PulseRider (PR), it is not necessary to introduce a microcatheter for stent delivery into the daughter branches from the neck, and it has less intraluminal metal. However, in some cases, securely introducing both leaflets into daughter vessels may be difficult, leading to coil herniation. This study aimed to present some technical issues in PR deployment. Methods: Fourteen PR procedures were performed in our institution between August 2021 and June 2023, and T-type PRs were used in all procedures. Four technical points during PR procedures are presented from our experience, as “technical options (Options 1-4)”. All procedures were carried out with T-type PR implants. Results: The PR was successfully placed in all interventions; however, in seven cases (50%), some technique trials were necessary because the leaflets did not unfold in the optimal directions. In Option 1, an introduction procedure with transposition of the daughter artery using a microcatheter is presented. In Option 2, the method for correction of the unfolded leaflet angle is demonstrated. In Option 3, another method for correction of the leaflets is shown. In Option 4, an effective method for neck protection during PR procedures is shown. Conclusion: Various options should be considered to achieve appropriate apposition of PR leaflets. These technical options may be safe and effective for successful PR deployment.

“…The incidence of complications following PulseRider implantation is reported to be 0%-8.8%, and most complications occur periprocedurally. A meta-analysis reported that perioperative complications of the PulseRider include aneurysm rupture, thrombus formation, vessel dissection, and ischemic stroke [ 1 , 2 ].…”

PulseRider (Cerenovus, Irvine, CA, USA) is a relatively novel device used for the treatment of wideneck aneurysms with a coil-assisted effect. However, treatment options for recurrent aneurysms after PulseRider-assisted coil embolization remain controversial. Here we report a case of recurrent basilar tip aneurysm (BTA) treated with Enterprise 2 after PulseRider-assisted coil embolization. A woman in her 70s underwent coil embolization for a subarachnoid hemorrhage with ruptured BTA 16 years ago. Recurrence was detected at 6-year follow-up, and an additional coil embolization was performed. Nevertheless, gradual recurrence still occurred, and PulseRider-assisted coil embolization was performed without any complications 9 years after the second treatment. However, recurrence was detected once more at 6-month follow-up. Thus, stent-assisted coil embolization using Enterprise 2 (Cerenovus) through PulseRider was selected for angular remodeling. Enterprise 2 was deployed between the right P2 segment of the posterior cerebral artery (PCA) and basilar artery (BA) after an effective coil embolization, which achieved effective angular remodeling between the right PCA and BA. The patient's postoperative course was uneventful, and no recanalization was detected after half a year. Although PulseRider is effective for wide-neck aneurysm treatment, recurrence remains a possibility. Additional treatment using Enterprise 2 is safe and effective with the expectation of angular remodeling.
