Distal cerebral vasospasm treatment following aneurysmal subarachnoid hemorrhage using the Comaneci device: technical feasibility and single-center preliminary results
Conclusion This initial experience suggests that distal mechanical angioplasty performed with the Comaneci-17 device for refractory vasospasm following aSAH seems to be safe, with good feasibility and efficacy.

First clinical multicenter experience with the new Pipeline Vantage flow diverter
Conclusions The new PV FD is safe and feasible for the treatment of intracranial aneurysms. The short-term occlusion rates are promising but need further assessment in prospective long-term follow-up studies.

Distribution of symptomatic cerebral vasospasm following subarachnoid hemorrhage assessed using cone-beam CT angiography
Conclusions Our study demonstrated that symptomatic cerebral vasospasm following aSAH did not involve arteries smaller than 900 µm, and frequently predominated in middle or distal segments. These results offer new insights into the potential management options for vasospasm using PBA.

Potential hemorrhagic risk of endovascular revascularization therapy due to recanalization of the dissected perforator in intracranial internal carotid artery dissection: A case report
CONCLUSION: To the best of our knowledge, this is the first case report demonstrating that the intracranial ICA dissection extends to the associated perforator. Considering the potential risk of subsequent hemorrhagic complications by recanalization of the dissected perforator, prudent postoperative management, including strict blood pressure control, is advisable following endovascular revascularization therapy against intracranial artery dissection involving perforators.PMID:35242437 | PMC:PMC8888279 | DOI:10.25259/SNI_938_2021
