Article Title: Subarachnoid Hemorrhage of Unknown Cause after Transvenous Embolization of Transverse Sigmoid Sinus Dural Arteriovenous Fistula Followed by Transarterial Embolization: A Case Report

doi: 10.5797/jnet.cr.2024-0030

Figure Lengend Snippet: Intraoperative DSA during TVE. ( A ) The lateral view shows the microcatheter inserted into the left sigmoid sinus through the tortuous confluence (white arrowhead). ( B ) The lateral view shows a partially packed left sigmoid sinus with several coils. ( C ) Frontal view shows the fractured microguidewire (black arrowhead). TVE, transvenous embolization

Article Snippet: However, attempts to reposition the microcatheter led to a fracture of the microguidewire (Synchro SELECT Guidewire Soft; Stryker, Portage, MI, USA), resulting in a 10-cm long piece of broken wire left behind in the transverse sinus.

Figure Lengend Snippet: ( A–D ) Intraoperative DSA via microcatheter during TAE, frontal view ( A and C ), and lateral view ( B and D ). Microcatheter is inserted via the petrosquamous branch of the middle meningeal artery into the left transverse sinus through the shunt point ( A and B , black arrowhead). Sphenopetrosal vein ( A and B , black arrow). Microguidewire remnant after fracture ( A and B , white arrowhead). Onyx cast front end ( C and D , black arrow). ( E ) Illustration of the treatment progress. A: left transverse sinus, B: left sigmoid sinus, black arrow: approach direction during TVE, dotted line arrow: approach direction during TVE. CVR, cortical venous reflux; OA, occipital artery; PA, posterior auricular artery; TAE, transarterial embolization; TVE, transvenous embolization

Article Title: A Case of Microguidewire and Neuroform Atlas Stent Entanglement Resulting in Extraction Difficulty

doi: 10.5797/jnet.cr.2023-0055

Figure Lengend Snippet: Intraoperative DSA image showing the microguidewire being entangled with the stent and stuck.

Article Snippet: We used a combination of a distal access catheter (Tactics; Technocrat Corporation, Aichi, Japan), microcatheter (Headway 17; Terumo Medical Corporation, Tokyo, Japan), and microguidewire (Synchro SELECT Soft 0.014 inch; Stryker, Fremont, CA, USA).

( B ) Image of a microguidewire (black arrow) being pulled by a gooseneck snare and a stent (white arrow) in the process of sliding down. ( C ) A stent (black arrows) that has slipped down and a newly placed stent (white arrows).

Figure Lengend Snippet: Image of the experiment. The stent was implanted into a clear artificial vessel, and a combination of SL-10 and microguidewire was used to guide the wire into the stent. This system was used to examine whether the stent and microguidewire will entangle.
