Gliederung

Text

Objective: The endovascular treatment of intracranial aneurysms has limitations in wide neck bifurcation aneurysms. pCONus is a stent-like, self-expanding Nitinol implant with four distal loops and a nylon cross within the distal stent shaft. The shaft is deployed to the parent vessel, with the distal loops inside the aneurysm at the neck level. The four loops and the nylon cross create an artificial border between the aneurysm neck and the parent artery. pCONus retains detachable coils within the aneurysms and prevents coil prolapse into the parent vessel. The technique of pCONus assisted coil treatment and the related safety and efficacy margins will be presented.

Method: 28 patients and wide neck bifurcation aneurysms were enrolled. pCONus treatment was chosen if surgical difficulty was anticipated or the patients refused operative treatment. 14 aneurysms were unruptured and not treated previously, 5 were previously coiled, and 9 were treated in the acute phase after SAH. Aneurysm locations were as follows: 11 MCA, 8 AcomA/A2, 8 BA and 1 PCA. The fundus size varied from 4–22 mm.

Results: Insertion and deployment of pCONus allowed a complete (8) or subtotal (9) aneurysm occlusion in 17 aneurysms, with 11 partial aneurysm occlusions. No hemorrhagic complication was encounterd. Follow-up DSA was available in 22 aneurysms, with complete (13), subtotal (6) and partial (3) occlusion.

Conclusions: pCONus assisted coil occlusion is a viable option for the endovascular treatment of wide neck bifurcation aneurysms. Long-term follow-up data is still missing.
