Is there a difference in catheter-related thrombosis between left- and right-sided arm ports and chest ports?

Current evidence indicates no overall difference in CRT incidence between left- and right-sided TIVAPs. However, the observed sample size-dependent association suggests that left-sided implantation may carry a slightly higher CRT risk in large cohorts. Clinicians may select the implantation side based on individual patient characteristics. However, large-sample, multi-center randomized controlled trials are needed to further validate these findings, particularly given the observed sample size-dependent differences.
