Observational Study
[Diagnostic utility of the hyomental distance ratio as predictor of difficult intubation at UMAE 25].
The hyomental distance ratio is defined as the ratio of the hyomental distances in neutral position and at head extension. The aim of the study was to establish the diagnostic utility as predictor of difficult intubation. ⋯ The hyomental distance ratio, as predictor of difficult intubation, has little utility.

This report describes a solution for a restenosis and for the fracture of a stent in the vertebral artery in a patient suffering from vertebrobasilar symptoms. Angiography demonstrates restenosis of a vertebral stent as well as its fracture and migration into the subclavian artery. ⋯ Pre-dilatation and kissing balloon techniques were applied in both the vertebral and subclavian arteries to modify the stent's dimensions and shape it into the form of a "ring." Postprocedural angiography demonstrated an excellent final result with the assistance of StentBoost visualization. Control angiography at six months also utilized StentBoost imaging and confirmed the patency of the bifurcation and that the stent was not displaced.
