title: [Use of Severini's coaxial catheters in gastrointestinal interventional radiology].
abstract: The growing importance of gastrointestinal interventional radiology has led to the development of new instruments and materials for the different proposed purposes. The authors present a set consisting of two coaxial catheters which was created for percutaneous transhepatic biliary drainage (Severini set). Its easy handling, adaptability and tolerability make it a versatile instrument in the hands of interventional radiologists for positioning large-calibre catheter (9-14 F) in deep sites. Hereafter are reported the results in 29 patients treated with different therapeutic aims and the use of the set for different pathologies. The catheters allowed a complete resolution of the collections communicating with the gastrointestinal tract in 4 of 5 patients. The catheter was inserted as a feeding tube in 22 patients. Finally, it was used as a gastrostomy catheter in 2 patients. Neither early nor late complications due to insertion or use of this set were observed.
