Comparing Patient Satisfaction With Transradial and Transfemoral Access

Most patients prefer transradial access when undergoing intra-arterial therapy for liver cancer, according to a study published in JVIR. A comparison of transradial and transfemoral access showed that the number of adverse events, as well as the procedure time, contrast agent volume, and patient radiation exposure were similar.

To determine differences in patient satisfaction and outcomes, researchers conducted a prospective, randomized, intra and interpatient controlled trial. The patients included in the trial had primary or metastatic liver cancer and were undergoing intra-arterial therapy to treat that cancer.

Patients had transradial access and transfemoral access at 2 different times and were given the opportunity to choose the access point for a third procedure, even if they did not undergo a third procedure. The 55 patients included in the study underwent a total of 124 intra-arterial procedures, and 36 of those patients had at least 1 intervention with transradial access and 1 with transfemoral access.

Of those 36 patients, 81% (29 patients) selected transradial access as their preferred access point for an additional procedure, while 19% (7 patients) selected transfemoral access.

There were comparable rates of complications associated with both access points, and procedure times were also similar. The contrast agent volume and radiation exposure to patients were also comparable between the groups. Additionally, operators were exposed to significantly less radiation with transradial access.
