Report the usefulness of completion cone-beam computed tomography (CBCT) as an adjunct tool during femoro-ilio-caval recanalization post stent placement.
Data from patients who underwent complex endovenous recanalization for chronic proximal outflow obstruction from January 2018 to May 2020 were analyzed. Two groups of patients were obtained based on the execution or not of completion CBCT. Outcomes, radiation, and contrast doses in the two groups were compared.
Fifteen patients (9 female, mean age 46.9 ± 13.3) in the control group and ten patients (7 female, 58.3 ± 14) in the CBCT group were included. In the CBCT group, one patient underwent an intraprocedural revision due to a residual lesion. The median total kerma area product (KAP) and the total volume of contrast injected were not statistically different in the two groups.
Completion CBCT after endovenous procedures might identify residual stenosis or stent malposition without a significant increase of total contrast injected and KAP.
报告在支架置入后股-髂-腔静脉再通术中使用锥形束 CT（CBCT）完成检查的作用。
分析了 2018 年 1 月至 2020 年 5 月期间因慢性近端流出道阻塞而接受复杂静脉腔内再通术的患者的数据。根据是否执行完成 CBCT，将患者分为两组。比较两组的结果、辐射和对比剂量。
对照组有 15 名患者（9 名女性，平均年龄 46.9±13.3），CBCT 组有 10 名患者（7 名女性，58.3±14）。在 CBCT 组中，1 名患者因残留病变而进行了术中修正。两组的总射线剂量面积乘积（KAP）和总造影剂注射量中位数无统计学差异。
静脉内手术后进行 CBCT 完成检查可以在不显著增加总造影剂注射量和 KAP 的情况下，发现残留狭窄或支架位置不当。
