Abstract

Introduction In this retrospective case series we evaluated stent-assisted coiling with a new low profile lasercut stent (pegasus, Phenox gmbh, Bochum, Germany)

Aim of Study To evaluate the performance of the pegasus stent system for aneurysm treatment.

Methods Patients treated with stent assisted coiling for intracranial aneurysm(s), with or without acute subarachnoid hemorrhage were included into the study. Clinical, imaging, procedural parameters and clinical and imaging follow up parameters were recorded and statistically evaluated.

Results 54 Aneurysms in 53 patients from 6 centers were included into the study. Mean age was 57 years (+-11,68). 29 patients were treated electively, 24 acutely (23 SAH, one partially thrombosed aneurysm with ischemic events). Intracranial procedure related events were recorded in 1 (6,9%) elective patient and in 3 SAH (12,5%) patients. Postprocedural ischemic complications occurred in 3 (12,5%) of the SAH patients and in 1 of the elective patients (3,45%), the latter not changing the mRS of the patient. Overall aneurysm occlusion was Raymond Roy (RR) I in 36 cases, RR II in 9 and RR IIIa in 9 cases and all stents were patent on final DSA run. On the first control which was available for 23 patients after 147,7 days (+-59,6) RR I was achieved in 22, RR II in 1 patient.

Conclusion Stent assisted coiling with the pegasus stent system seems safe and effective.
