BACKGROUND: The femoral artery is the standard route for transarterial chemoembolization (TACE); however, it is negatively associated with the quality of life of patients, and carries an increased risk of deep vein thrombosis in the lower limbs. We employed the distal radial approach to TACE to assess its feasibility and safety. METHODS: We conducted a retrospective study at the First Hospital of Jilin University from August 1, 2020 to October 31, 2023. To be eligible for inclusion in the study, the patients had to meet the following main inclusion criteria: (I) have undergone a preoperative imaging (abdominal computed tomography enhancement or magnetic resonance dynamic enhancement) examination, or have a pathologically confirmed diagnosis of primary liver cancer, and a Child-Pugh score of A or B; and (II) have undergone distal radial artery puncture. The primary endpoint of this study was the success rate of distal radial artery puncture. The secondary endpoints were complications and the duration of the puncture. RESULTS: Among the 343 patients with primary liver cancer (of whom 236 were male and 107 were female), a total of 1,315 distal radial artery punctures were attempted. The success rate was remarkably high at 95.13% (1,251/1,315), with only 64 cases requiring an alternative approach due to failed puncture. The average puncture duration was 20±7.43 minutes. No bleeding and hematoma, no arterial dissection and pseudoaneurysm formation were observed on ultrasound, and the radial pulse was palpable in all patients, highlighting the safety of the procedure. Further, no adverse events of vascular occlusion were observed among the 12 patients who received 6 or more punctures, indicating the sustainability of the distal radial artery access under the premise of adequate vascular protection. The development of this technique requires a learning curve of at least 50 cases to break through the learning baseline and be proficient in distal radial artery blind puncture. This may be the reason why many interventional physicians are reluctant to perform this procedure, adapting to the femoral approach with a shorter learning curve. CONCLUSIONS: The distal radial artery approach is feasible and safe in hepatic arterial chemoembolization, and should be widely promoted in TACE.
