Objective To discuss the application of gelatin sponge-hemocoagulase plugging agent in patients with pulmonary puncture bleeding.Methods The clinical data of 43 patients with hemorrhage caused by DSA-guided lung puncture biopsy,who received gelatin sponge-hemocoagulase plugging agent treatment at the Jining Municipal First People's Hospital of China between September 2021 and May 2023,were collected,and the hemostatic effect of gelatin sponge-hemocoagulase plugging agent was analyzed.Results Successful lung puncture needle biopsy was achieved in all the 43 patients.The puncture needle channel occlusion was accomplished by using gelatin sponge-hemocoagulase plugging agent.Five minutes after occlusion treatment,in one patient,whose moderate hemoptysis with moderate bleeding shadow before puncture needle biopsy changed to bloody sputum,the intrapulmonary bleeding shadow displayed on image became slightly enlarged when compared the size five minutes ago,while in all the remaining patients successful hemostasis was achieved,the hemoptysis disappeared and the pulmonary hemorrhage shadow was similar to that five minutes ago.No occlusion-related complications occurred in all patients.Conclusion For the treatment of pulmonary hemorrhage caused by DSA-guided lung puncture biopsy,gelatin sponge-hemocoagulase plugging agent is clinically safe and effective.

Objective To discuss the application value of XperCT combined with needle-guided Glubran-2 glue for small pulmonary nodule localization in thoracoscopic pulmonary nodule resection.Methods The clinical data of 67 patients,who received XperCT combined with needle-guided Glubran-2 glue for small pulmonary nodule localization before thoracoscopic resection of a single small pulmonary nodule at the Jining Municipal First People's Hospital of China between June 2018 and February 2023,were retrospectively analyzed.The size of the pulmonary nodule,the maximum vertical distance from the visceral pleura to the lesion,the technical success rate of localization,the number of puncturing times,the complications,the time spent for operation,and the postoperative pathological diagnosis were recorded.Results The average size of the small pulmonary nodules in the 67 patients was 8.7 mm,and the average vertical distance from the visceral pleura to the lesion was 19.4 mm.Successful preoperative localization of nodule was accomplished in all patients.The average number of puncturing times was 1.1,and no serious complications occurred.The average time spent for operation was 12.7 min.Definite pathological results were obtained in all 67 patients.Conclusion XperCT combined with needle-guided Glubran-2 glue for small pulmonary nodule localization carries advantage of accurate localization with fewer complications.Therefore,this technique is a highly-efficient and quickly-accomplished positioning method,and it is highly valuable in clinical practice.(J Intervent Radiol,2024,33:623-626)

Objective To observe the effect of transcatheter arterial embolization(TAE)with Glubran-2 glue for treating hemorrhage after percutaneous transhepatic cholangial drainage(PTCD).Methods Data of 17 patients with hemorrhage after PTCD who underwent TAE with Glubran-2 glue were retrospectively analyzed.The technical success rate,clinical success rate and complications were observed.The red blood cell(RBC)and hemoglobin(Hb)on the day of TAE and the next day of TAE were compared,also the glutamic-pyruvic transaminase(GPT)level before TAE,on the next day of TAE,on the second and the fourth day after TAE,respectively.Results The offending vessel of bleeding was successfully embolized in all 17 cases,both technical success rate of TAE and clinical success rate of hemostasis were 100%.There was no serious complication such as liver abscess,septicemia nor pulmonary embolism.No significant difference of RBC nor Hb was found between the day of TAE and the next day of TAE(both P＞0.05).GPT before TAE was lower than the next day of TAE and the second day after TAE(P＜0.05),while no significant difference of GPT was found before TAE and 4 days after TAE(P＞0.05).Conclusion TAE with Glubran-2 glue for treating hemorrhage after PTCD was safe and effective.
