Background Endovascular therapy of complex bifurcation aneurysms is often accessible only by stent-assisted coil embolization.
Methods We report 62 consecutive elective aneurysm coil embolizations facilitated by Pegasus HPC stent in Y configuration. The technical approach of stent placement, catheter exploration, and coil embolization was identical using intermediate catheter (Sofia 5F) and microcatheter (SL10, direct stent exploration without jailing). Closure rates, complication rates, and regimen of platelet aggregation inhibition were evaluated.
Results Simple antiplatelet therapy was required in 24 cases 42%. Transradial access was chosen in 17 cases. The periprocedural complication rate was 5% (1 case with KM encephalopathy with complete recovery). There were no bleeding, ischemic events, or in-stent stenosis at 3- or 6-month follow-up. The closure rate (Raymon-Roy I and II) was 96.8% at 6 months.
Discussion and Conclusion Endovascular coil embolization of complex broad-based bifurcation aneurysms using Pegasus HPC stent in Y configuration is technically very accessible. Simple platelet aggregation inhibition with the Pegasus HPC stent appears safe.
