Summary of lapse analysis and experience with CT-guided percutaneous lung biopsy / 实用放射学杂志

Objective To investigate the complications of CT-guided percutaneous lung biopsy(CT-PTNB)and its correlation with improper operation.Methods The clinical data of 360 patients who underwent lung tumor needle biopsy were collected.The complications occurred in the process of needle biopsy and their correlation with improper operation were summarized,and the experience was further summarized to increase the success rate of needle biopsy and reduce the occurrence of complications.Results Biopsy tissue was successfully obtained in all 360 patients.There were 84 cases with complications after puncture,including 67 cases with pneumothorax,59 cases with hemorrhage(5 cases with hemoptysis,59 cases with needle tract hemorrhage with pulmonary hemorrhage,6 cases with intrathoracic hemorrhage),9 cases with subcutaneous emphysema of chest wall,and 3 cases with chest wall puncture point pain,and all patients did not undergo surgical treatment.All patients recovered from symptomatic treatment such as bed rest,hemostasis,anti-inflammatory and oxygen inhalation.Only 6 patients with pneumothorax had increased volume of pneumothorax after operation and underwent closed thoracic drainage,and all of them were decannulated successfully.No air embolism and other rare complications occurred.Conclusion The appropriate puncture path should be selected according to the different conditions of the patient.At the same time,the anatomy of the chest wall and lung should be familiar with,and pay attention to all the details of the needle biopsy process to reduce the occurrence of errors.

The clinical value of selection of the puncture path in performing CT-guided pericardial drainage / 介入放射学杂志

Objective To discuss the optimalselection of the puncture path in performing CT-guided pericardial drainage,and to evaluate its clinical feasibility and safety.Methods A total of 114 patients with pericardial effusion,who were admitted to authors' hospital during the period from May 2013 to March 2016,were enrolledin this study.The appropriate body position and suitable needle-puncturing route were selected,and CT-guided pericardial drainage with Seldinger'stechnique was performed.Results Successful puncturing and catheter drainage was obtained in all 114 patients,no any serious complication occurred.The time used for manipulation was 18-30 min.Conclusion The use of right puncture path is of great importance for the performance of CT-guided pericardial drainage for pericardial effusion,this technique is highly feasible and safe for relieving the clinical symptoms of pericardial tamponade.

Application of regional anesthesia under ultrasonic guidance for establishing puncture path of superficial tumor biopsy / 中华全科医师杂志

To explore the value of local anesthesia under ultrasonic guidance for establishing puncture path of superficial tumor.A total of 144 patients with superficial tumor received local pre-puncture anesthesia under ultrasonic guidance so that all lesions were targeted.Transient aggregation of narcotics was applied for raised (n =12) or superficial (n =15) skin lesions.The clarity of scanning acoustic window was enhanced,the puncture distance of tumor broadened and the mass of axial changed to obtain a longer lymph node cortex.The damage of blood vessels occurred easily due to tumor closeness to large blood vessel or shortened puncture path in 17 cases.Anesthetic drug was injected between tumor and blood vessels to enlarge the thickness for visualizing the puncture needle tract clearly.And puncture was accomplished under the guidance of color Doppler.Therefore a puncture path can be created effectively with local anesthesia by ultrasonic guidance.
