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 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.
