Abstract

Abstract: Objective The aim of this study was to investigate the clinical value of three-dimensional reconstruction based on cone-beam CT (CBCT) for the identification of supplying arteries in patients with primary liver cancer (PLC) underwent hepatic arterial chemoembolization (TACE) . Methods A total of 103 patients with PLC were encountered in our hospital between January 2018 and January 2021, and all patients with PLC underwent TACE. During TACE process, 54 patients received DSA examination and 49 patients received CBCT-based three-dimensional reconstruction examination to find blood-supplying arteries. All patients were followed-up for 3 months after TACE. Results The operative time, the amount of radiation, and the success rate of superselective intubation rate in patients underwent CBCT-bade 3D reconstruction were(42.3±5.1)min,(209.4±27.6)mGy and 93.9%, significantly different compared to (35.2±3.0)min, (142.3±15.2)mGy and 66.7% in patients underwent DSA check-up (P＜0.05); the identification of supplying arteries meeting the diagnostic requirements in CBCT-based 3D reconstruction was 100.0%, the detection of lesions was 93.9%, and the complete deposition of lipiopine was 91.8%, all significantly superior to 74.1%, 70.4% and 72.2% in patients underwent DSA (P＜0.05); at the end of three month after operation, the effective rate and disease control rate in patients underwent CBCT-based 3D reconstruction were 83.7% and 89.8%, both significantly higher than 57.4% and 68.5%(P＜0.05)in patients underwent DSA. Conclusion As compared with DSA examination during TACE, the CBCT-based three-dimensional reconstruction for identify tumor supplying blood arteries in patients with PLC could obtain better short-term outcomes, however, the implementation of CBCT-based three-dimensional reconstruction might also prolong the operative time and increase the radiation exposure, which should take into consideration in clinical practice.
