Clinical application value of the cone beam CT software in detection of tumor-feeding arteries in transarterial chemoembolization
Objective To explore the clinical application value of software in detection of tumor-feeding arteries FPFL based on cone beam computed tomography(CBCT)in the transarterial chemoembolization(TACE).Methods A retrospective analysis was conducted on 120 patients who underwent TACE treatment.According to whether the tumor-feeding arteries detection software FPFL was used during TACE procedures,the patients were divided into FPFL group and traditional treatment group.The propensity score matching(PSM)method was used to match the two groups in a ratio of 1︰1,with the matching variables including age,gender,number of lesions,Eastern Cooperative Oncology Group(ECOG)score,maximum tumor diameter,and alpha-fetoprotein(AFP)value.Ultimately,a total of 11 pairs of patients were successfully matched between the FPFL group and the traditional treatment group,and then the differences of intraoperative clinical data between the two groups were analyzed.Results The surgeon identified a total of 38 tumors in both groups of patients during the operation,and then 92 tumor supplying arteries were recognized and confirmed.The identification accuracy was 93%for the traditional treatment group and 100%for the FPFL group.The technical success rates of both groups of patients were 100%.Compared with the traditional treatment group,the FPFL group had the reduction of 28%in fluoroscopy expo-sure time,37.12%in total air release energy,52.38%in dose-area product(DAP)value,52.63%in digital subtraction angiography(DSA)sequence number,39.26%in iodine contrast agent dosage,and 40.49%in surgical time.Conclusion The FPFL software can effec-tively improve the identification and confirmation of tumor-feeding arteries,significantly reduce the surgical time,iodine contrast agent dosage and radiation dose,and optimizes the surgical process.
