Initial and follow-up high-resolution vessel wall MRI study of spontaneous cervicocranial artery dissection
ConclusionsMultiple initial factors were found to be related to stroke occurrence and anatomical outcomes of sCCAD. High-resolution VW-MRI may provide valuable insights into the pathophysiology and evolution of sCCAD.Clinical relevance statementInitial and follow-up high-resolution vessel wall MRI may help elucidate the pathophysiology of spontaneous cervicocranial artery dissection and provide important insights into the evolution and further facilitate the optimal management of patients with spontaneous cervicocranial artery dissection.Key Points•Clinical and imaging factors, as well as the status of primary collateral...

Endovascular repair combined with in situ fenestration for new ‐onset or residual arch dissection in patients underwent aortic replacement
ConclusionOur preliminary experience suggests that endovascular total arch repair combined with ISF technique is a viable, effective and safe option for treatment. Our mid-term results have been promising, but we acknowledge the need for further evaluation to assess long-term outcomes and durability.

The balloon occlusion sheath for stroke (BOSS) balloon guide catheter for stroke intervention: Safety and technical success
CONCLUSIONS: The BOSSTM balloon-guide catheter is a safe and technically effective adjunctive device for mechanical thrombectomy of acute ischemic stroke due to large vessel occlusion.PMID:37649344 | DOI:10.1177/15910199231198273

A review of acute ischemic stroke caused by distal, medium vessel occlusions
Interv Neuroradiol. 2023 Aug 29:15910199231197616. doi: 10.1177/15910199231197616. Online ahead of print.ABSTRACTAcute ischemic stroke (AIS) due to distal, medium vessel occlusion (DMVO) is increasingly recognized as the next frontier for mechanical thrombectomy. Distal, medium vessel occlusions are typically defined as an occlusion in the following arteries: anterior cerebral artery, M2-M4 segments of the middle cerebral artery, posterior cerebral artery, posterior inferior cerebellar artery, anterior inferior cerebellar artery, and superior cerebellar artery. It is estimated that 25-40% of all AIS is due to DMVO. Because...

Mechanical thrombectomy beyond 24 hours from last known well in tandem lesions: A multicenter cohort study
CONCLUSIONS: Our results suggest that MT appears to benefit patients with TLs beyond 24 hours from LKW. Future prospective studies are warranted.PMID:37642978 | DOI:10.1177/15910199231196960

Device use trends in neuroendovascular procedures in the United States from 2015 to 2020
CONCLUSION: Our study demonstrates an increase in the use of flow-diverting stents, nondiverting stents, carotid stents, and reperfusion devices for acute ischemic stroke intervention between 2015 and 2020. Coil use for aneurysmal treatment has declined.PMID:37642975 | DOI:10.1177/15910199231196329

Effect of mechanical thrombectomy with and without intravenous thrombolysis on the functional outcome of patients with different degrees of thrombus perviousness
ConclusionPatients with thrombi of lower perviousness were recommended to undergo intravenous alteplase followed by endovascular thrombectomy, and those with thrombi of higher perviousness could undergo thrombectomy alone.
