Purpose To compare transfemoral approach (TFA) and transradial approach (TRA) in patients undergoing hepatic chemoembolization in terms of safety, feasibility, and procedural variables, including fluoroscopy time, radiation dose (reference air kerma [RAK]), and patient preference. Materials and Methods A single-center prospective intrapatient comparative study was conducted with 42 consecutive patients with hepatic malignancies who received 2 consecutive treatment sessions of unilobar hepatic chemoembolization within a 4-week interval over a 6-month period with both TRA and TFA. All procedures were performed by 1 interventional radiologist who assessed the eligibility of patients for inclusion in the study. The primary endpoint was intraprocedural conversion rate. Secondary endpoints were access site complications, angiographic and procedural variables, and evaluation of patient discomfort and preferences. Results A 100% technical success rate and a crossover rate of 0% were recorded. There were no major vascular complications and similar rates of minor complications (4.8% for TRA, 7.1% for TFA; P =.095), which were self-limited and without any clinical sequelae. TRA treatments required a significantly longer preparation time for the procedure (P =.008) with no significant differences for other procedural variables. Greater discomfort at the access route and patient inability to perform basic activities after the procedure were recorded for TFA (P <.001). TRA was preferred by 35 patients (35/42) for potential future transarterial procedures. Conclusions TRA is safe and feasible for transarterial hepatic chemoembolization, with high technical success, low overall complications, and improved patient comfort.
