    BackgroundThe classic percutaneous balloon compression (PBC) technique is used to complete an operation under the guidance of C-arm radiography under general anesthesia, making communication with patients during the operation impossible. It is not accurate or objective to predict the classic technique's curative effect solely by determining whether the projection of the x-ray lateral image of the filled balloon is pear-shaped.ObjectivesThis study aimed to upgrade classic PBC to awake computed tomography (CT)-guided PBC technology under conscious local anesthesia and analgesia monitoring.Study DesignProspective clinical study.SettingDepartment of Anesthesiology and Pain Medical Center, Jiaxing, People's Republic of China.MethodsPuncture was designed and guided by CT scanning, and the curative effect was assessed by asking the patients about what they are feeling during the operation.ResultsCT can design the puncture path and accurately guide puncture, observe the position and shape of the balloon through 3-dimensional reconstruction during the operation, and judge the curative effect according to the patient's chief concern.LimitationsLocal anesthetic analgesia is not perfect, resulting in some patients experiencing pain during surgery.ConclusionsPBC can be completed under conscious local anesthesia and analgesia. Its curative effect and operative end standard can be determined according to the patient's chief concern. Under CT guidance, the puncture path can be designed to complete an accurate puncture and to intuitively understand the position and shape of the balloon.
