To describe a particular technique derived from neuroradiologic and cardiologic interventional procedures that can sometimes solve complex situations even in peripheral interventional radiology.

Balloon-assisted technique (BAT) consists in the use of a balloon catheter advanced in parallel fashion to the main catheter in the same artery to overcome problems during endovascular interventions. In literaturethe use ofBAT is widely reported 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 conditions. In peripheral endovascular interventions BAT is rarely described and only few case reports can be found. We describe three different cases...

Case description: Case n. 1. Female, 65 yo. An abdominal CT examination identified a 5 cm aneurysm of the pancreatic-duodenal artery (Fig.1) probably due to an occlusion of the origin of the celiac trunk caused by Dunbar Syndrome. Follow-up CT demonstrated a mild enlargement of the aneurysm and for this reason an endovascular treatment was proposed. Considering that coiling of the aneurysm was not an option due to the risk of occlusion of the efferent vessel feeding the gastroduodenal, hepatic and splenic arteries we considered...

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 <...
