Prone Transradial Catheterization for Combined Single-Session Transarterial Embolization and Percutaneous Posterior Approach Cryoablation of Solid Neoplasms

Cardiovasc Intervent Radiol. 2017 Jul;40(7):1026-1032. doi: 10.1007/s00270-016-1529-5. Epub 2016 Dec 5.


Transradial access (TRA) has been associated with improved post-procedure hemostasis and patient satisfaction, and decreased hemorrhagic complications, sedation requirements, recovery times, and procedure-related costs when compared with traditional transfemoral catheterization. Supine TRA has been described for the treatment of myocardial infarctions, aortoiliac and femoropopliteal stenoses, and a variety of neoplasms. This original research describes prone transradial catheterization to facilitate combined single-session transarterial embolization and percutaneous cryoablation of solid neoplasms from a posterior approach without repositioning. Prone TRA access, transarterial embolization, and percutaneous cryoablation were successful in all cases described. Mean procedure time was 210 min (range: 140-250 min). One minor complication, transient bacteremia which responded to antibiotics, was reported. No major complications occurred.
