To investigate the diagnostic efficacy of inflator-monitored balloon-occluded retrograde transvenous obliteration (ImBRTO) in detecting balloon rupture and to evaluate the efficacy and safety of the ImBRTO in treating gastric varices.
Between June 2018 and June 2024, 31 consecutive patients (age: 61.7 ± 12.4 years; male 20, female 11) underwent ImBRTO for gastric varices. An occlusion balloon was inflated with an inflation device to monitor for balloon rupture during sclerosing, maintaining the balloon inflation for at least 3 h.
The technical success rate was 100%. The incidence of balloon rupture was 6.5% (2/31), both diagnosed by a pressure drop in the inflation device. In one of the two patients, catheter replacement and an additional injection of a sclerosing agent were required due to early balloon rupture (< 3 h). Clinical success and complete elimination of gastric varices were achieved in all cases. No procedure-related complications were observed. There were no cases of recurrent variceal bleeding at the end of the follow-up (median: 5.2 months).
ImBRTO proves to be an effective and safe technique for treating gastric varices. The real-time monitoring of balloon integrity allows for timely decisions, resulting in excellent clinical outcomes.
探讨充气监测球囊闭塞逆行经静脉闭塞术（ImBRTO）在检测球囊破裂方面的诊断效能，并评估ImBRTO治疗胃静脉曲张的疗效和安全性。
2018年6月至2024年6月，31例连续患者（年龄：61.7±12.4岁；男性20例，女性11例）接受ImBRTO治疗胃静脉曲张。使用充气装置对闭塞球囊进行充气，在硬化治疗期间监测球囊破裂情况，使球囊充气至少维持3小时。
技术成功率为100%。球囊破裂发生率为6.5%（2/31），均通过充气装置压力下降诊断。在这两名患者中的一名患者中，由于球囊早期破裂（<3小时），需要更换导管并额外注射硬化剂。所有病例均取得临床成功且胃静脉曲张完全消除。未观察到与手术相关的并发症。随访结束时（中位时间：5.2个月）无复发性静脉曲张出血病例。
ImBRTO被证明是一种治疗胃静脉曲张的有效且安全的技术。对球囊完整性的实时监测能够及时做出决策，从而取得优异的临床效果。
