Conclusion
In literature is widely reported the use of "balloon-assisted" technique in neurointerventional radiology referring in particular to the coiling of wide neck cerebral aneurysms and in interventional cardiology for the catheterization of tortuous arteries in anatomic unfavorable situations.
The use of BAT in peripheral interventional radiology is rarely reported and only few case reports are anedoctally reported.
Some Authors describe the use of this technique in performing carotid stenting in carotid artery presenting an acute angle at the origin.
In this situation an angle < 90° represents an important impediment for the technical success of the procedure and can be solved by the use of a balloon inflated close to the distal end of the wire in order to improve stability and reach the support needed to advance the materials for stenting in the correct position [1].
Another use of BAT is described for advancing long sheats through freshly placed stents or anatomical difficult vessels,
in particular pulmonary veins [2] and to enable superselective catheterization of inaccessible small arteries [3].
A particular use of BAT is also described in a case of removal of an inferior vena cava tilted filter which presented an apex in contact with the caval wall and covered by an endothelial cap [4].
These are some possible applications of BAT and the cases here presented suggest further uses of this technique.
More than a technique we believe that BAT is a “maneuver” to be tailored for every complex situation with specific materials.
