Abstract

The PulseRider (Cerenovus, Johnson & Johnson Medical Devices, New Brunswick, NJ, USA) is a neck reconstruction device that is used for the treatment of unruptured wide-necked bifurcation aneurysms. Herein, we describe the case of a 51-year-old male patient with a basilar apex aneurysm who was treated with PulseRider but had post-procedural brainstem infarctions caused by one of the proximal markers covering the origin of a perforator. In such cases, repositioning of the PulseRider should be performed to avoid infarctions.

Highlights

The PulseRider (Cerenovus, Johnson & Johnson Medical Devices, New Brunswick, NJ, USA) is a neck reconstruction device that is used for the treatment of unruptured wide-necked bifurcation aneurysms
The device is characterized by a low metal mass that is concentrated at the aneurysmal neck
Only a few ischemic complications have been observed during followup.[4,9]

Summary

Background

The PulseRider (Cerenovus, Johnson & Johnson Medical Devices, New Brunswick, NJ, USA) is a neck reconstruction device that is used for the treatment of unruptured wide-necked bifurcation aneurysms. The PulseRider has been used for wide-necked bifurcation aneurysms with neck widths of 4 mm or dome-to-neck ratios < 2, and parent vessel diameters must range from 2.7 mm to 4.5 mm. The device is characterized by a low metal mass that is concentrated at the aneurysmal neck. Few ischemic complications related to its use have been reported
