Insertion of a totally implantable venous access port in a patient with isolated persistent left superior vena cava: A case report / 中国胸心血管外科临床杂志

@#Persistent left superior vena cava (PLSVC) with absence of right superior vena cava (SVC), also known as isolated PLSVC, is a relatively rare type of congenital body venous malformation. Isolated PLSVC is asymptomatic, however, it will bring clinical difficulties to the implantation of the totally implantable venous access port (TIVAP). We reported a 41 years, male patient with esophageal cancer, who needed neoadjuvant chemoimmunotherapy. Through doppler ultrasonography, computed tomography (CT) and vascular 3D-reconstruction, we found him to be a patient with PLSVC with absence of right SVC before the insertion of TIVAP. Hence, we chose the left approach in which the needle was inserted into the sternocleidomastoid clavicular head lateral notch in left supraclavicular fossa as the puncture point. The depth of the catheter tip from the root of the neck to the puncture point was 21.5 cm and the catheter tip was located at the junction of the PLSVC and the right atrium, at the dilated coronary sinus. The procedure was successful and the patient received expected neoadjuvant chemotherapy combined with immunotherapy after operation, and anticoagulant therapy was performed to prevent thrombosis in coronary sinus and superior vena cava. There was no major catheter-related complication during the period of TIVAP.

E sports and depression, opportunities and challenges: rational thinking based on adolescent health and exercise intervention / 中国学校卫生

Abstract@#Teen E sports and their negative impact should not be underestimated. The effects of gaming, as an emerging sport, should be examined to determine whether it plays an active role in contributing to the onset of adolescent depression. Therefore, this study outlines the development status of E sports, analyzes the influence of E sports on adolescent depression, and highlights the hidden concerns that E sports pose for the mental health development of adolescents. While taking into account the advantages of E sports and exercise intervention programs, an emphasis should be placed on the prevention of depression, and feasible suggestions and countermeasures should be put forward to promote E sports, while at the same time safeguarding the healthy and orderly development of adolescent mental health.
