Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
This study is a multicenter prospective, open-label, randomized controlled study, including 5 study centers: Renmin Hospital of Wuhan University, Beijing Friendship Hospital, Capital Medical University, The Southwest Hospital of Army Medical University, Affiliated Hospital of Zunyi Medical University and Shanxi Coal Center Hospital. The total sample size is 150 patients, with 75 patients in the EUS evaluation group and 75 patients in the control group, respectively.
The patients who meet the inclusion and exclusion criteria are randomly assigned to EUS evaluation group and control group by using block randomization. The EUS evaluation group uses EUS to observe the diameter and blood flow of residual variceal veins after endoscopic cyanoacrylate injection for GV to evaluate the embolization effect. Endoscopic cyanoacrylate injection is performed again if the diameter of variceal vein is larger than 5 mm and with blood flow signal. After the injection, the blood flow signal is confirmed disappear by EUS. The control group return to the ward after endoscopic cyanoacrylate injection, without EUS evaluation. During the study, the patients are followed up for at least 12 months, and they are requested to return to the hospital for follow-up at 1 month, 3 months, 6 months and 12 months after the treatment, respectively. The data of baseline, treatment, postoperative and follow-up of the two groups are need to collect.
The primary outcome of this study is rebleeding rate. Secondary outcomes are eradication rate of GV, mortality rate, retreatment, and cost-effectiveness.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
EUS group
The EUS group uses endoscopic ultrasound to observe the diameter and blood flow of residual variceal veins after endoscopic cyanoacrylate injection for gastric varices to evaluate the embolization effect.
Endoscopic ultrasound
Using endoscopic ultrasound (EUS) to observe the diameter and blood flow of residual variceal veins after endoscopic cyanoacrylate injection for gastric varices to evaluate the embolization effect. Endoscopic cyanoacrylate injection is performed again if the diameter of variceal vein is larger than 5 mm and with blood flow signal. After the injection, the blood flow signal is confirmed disappear by endoscopic ultrasound. Patients in the EUS group required endoscopic ultrasound assessment at each stage of the follow-up period.
Control group
The control group doesn't perform endoscopic ultrasound after endoscopic cyanoacrylate injection for gastric varices.
No interventions assigned to this group

Endoscopic cyanoacrylate injection is performed again if the diameter of variceal vein is larger than 5 mm and with blood flow signal. After the injection, the blood flow signal is confirmed disappear by endoscopic ultrasound. Patients in the EUS group required endoscopic ultrasound assessment at each stage of the follow-up period.
