Stent’s strut technique

When stent assisted coiling (SAC) is performed for the treatment of intracranial aneurysm, the technique of catheter tip placement into the aneurysm sac can be divided into 2 methods: the catheter jailing technique and through the stent’s strut technique.

Although the conventional catheter jailing technique eliminates some of the drawbacks of through the stent’s strut technique, it does not offer a possibility of modifying the microcatheter position within the aneurysm sac, which further limits the operator’s ability to reposition the coil delivery catheter tip. As a novel method for overcoming such drawbacks of catheter jailing technique, the semi-jailing technique (SJT), which was first described for cerebral aneurysms by Hong and colleagues in 2009, provides stent-assisted remodeling of the aneurysm neck during coil embolization without grasping the coil delivery microcatheter ¹⁾.
