Summary
The pCONUS2 and pCONUS2 HPC devices demonstrate high technical success and low complication rates for treating bifurcation aneurysms. These devices achieve good rates of adequate aneurysm occlusion, indicating their effectiveness in endovascular procedures.
Area of Science:
- Neurosurgery
- Endovascular Therapy
- Cerebrovascular Disease
Background:
- Bifurcation aneurysms pose significant challenges in endovascular treatment.
- Various techniques and devices are employed to manage these complex vascular lesions.
Purpose of the Study:
- To evaluate the safety and efficacy of the pCONUS2 and pCONUS2 HPC devices in treating bifurcation aneurysms.
- To report on the technical success, complication rates, and angiographic outcomes of these devices in a multicenter setting.
Main Methods:
- Retrospective review of prospectively maintained databases from three neurointerventional centers.
- Inclusion of patients treated with pCONUS2 or pCONUS2 HPC devices for bifurcation aneurysms between February 2015 and August 2021.
- Collection of data on demographics, aneurysm characteristics, procedural details, complications, and angiographic follow-up.
Main Results:
- 55 patients with 56 aneurysms were treated, predominantly at the MCA bifurcation.
- Procedural technical success rate was 98.2% with a low permanent morbidity (1.8%) and 0% mortality.
- Delayed angiographic follow-up showed adequate occlusion in 83.4% of aneurysms at a median of 12 months.
Conclusions:
- The pCONUS2 and pCONUS2 HPC devices offer a high technical success rate for bifurcation aneurysms.
- These devices are associated with low complication and retreatment rates, alongside good occlusion rates.
- Further prospective studies are warranted to confirm these findings.
