Clinical Impact and Safety of Non-Target Punctures (NTP) during Portal Vein Access in TIPS Procedure.

NTPs during the portal access of TIPS procedures are associated with low complication risk. However, when extracapsular punctures are combined with other NTPs, a more severe complication, including mortality, can occur. Nevertheless, all patients with NTP should be closely monitored at a higher level of care after TIPS placement.
