摘要：

Establishing a long-term vascular access in patients exhibiting vascular access exhaustion is challenging. In this study, we reported a case of a direct catheterization in the superior vena cava of a hemodialysis patient with vascular access exhaustion and original dysfunctional catheter inserted via the left internal jugular vein. The direct catheterization was performed with cuffed tunnel catheter (CUFF) and guided by digital subtraction angiography (DSA) and multidetector computed tomography venography (MDCTV). The DSA and MDCTV results revealed an occlusion in the right innominate vein and thromboses in the left innominate, right internal jugular, subclavian, and femoral veins. The distal end of the superior vena cava was localized clearly by the original CUFF under DSA. Directed at the distal end of the superior vena cava, a 0.5-cm secondary puncture was introduced below the lateral head of the sternocleidomastoid muscle via the right neck area. This study is one of the few reports regarding direct catheterization of CUFF via the superior vena cava of a patient with vascular access exhaustion and CUFF dysfunction on the left internal jugular vein. We believe that our study can provide a new alternative for inserting central venous catheter for such patient.

摘要： Cases of acute pancreatitis induced by organophosphate intoxication are encountered occasionally in clinics, but very few of them develop into severe pancreas necrosis and irreversible pancreatic function impairment. Here, we report a 47-year-old female organophosphate poisoning case after ingestion of massive insecticides; she was considered to have total necrosis and function failure of the pancreas via serum amylase test, glucose level test, and CT imaging. The patient exhibited no relief under the regular medicine treatment, which included sandostatin, antibiotics, intravenous atropine, and pralidoxime methiodide. She received percutaneous catheterization and drainage of pancreatic zone to expel hazardous necrotic waste, also by which the pathogenic evidence was obtained and the antibiotics were adjusted subsequently. The patient recovered gradually, was discharged after 2 weeks, and was prescribed with oral pancreatin capsules before meals and hypodermic insulin at meals and bedtime to compensate the impaired pancreatic function.
