Comparison of Aspiration and Stent Retriever in Acute Basilar Artery Occlusion: A Subanalysis of the K-NET Registry.

Objective: Recent studies of endovascular thrombectomy (EVT) for anterior circulation stroke have revealed that contact aspiration (CA) and stent retriever (SR) achieve equivalent rates of effective reperfusion, neurological outcomes, and incidence of complications. However, comparative studies on the safety and efficacy of these techniques, particularly in the setting of basilar artery occlusion (BAO), are still lacking. This study aimed to compare the efficacy and safety of CA and SR thrombectomy for BAO using multicenter registry data, and to identify factors associated with better functional outcomes.

Reversible cerebral vasoconstriction syndrome in idiopathic multicentric Castleman disease under treatment with tocilizumab.

Background: Idiopathic multicentric Castleman disease (iMCD) is a rare polyclonal lymphoproliferative disorder characterised by systemic inflammation resulting from overproduction of interleukin 6 (IL-6). While iMCD primarily affects the lymph nodes and related tissues, it can also rarely involve the central nervous system.

Case Presentation: We report the case of a 58-year-old female patient with at least a 3-year history of iMCD, who experienced acute thunderclap headaches due to reversible cerebral vasoconstriction syndrome (RCVS).

Coaxial Method of PTA Balloon and Aspiration catheter using the delivery wire of a stent retriever for tandem occlusion: CoMBAt tandem occlusion.

Purpose: Tandem occlusion, in which the intracranial artery is obstructed along with proximal carotid occlusive or stenotic lesions, occurs in 10-15% of patients with large vessel occlusion. Our study introduces a novel technique for tandem occlusion treatment that involves the simultaneous coaxial deployment of a percutaneous transluminal angioplasty balloon and aspiration catheters with the delivery wire of a stent retriever. After percutaneous transluminal angioplasty of the carotid lesion with a thin balloon catheter, the aspiration catheter was advanced over the balloon to eliminate the ledge between the catheter tip and delivery wire.
