简介：
Overview
This article discusses a technique for inserting a central venous catheter using real-time ultrasound guidance via the right supraclavicular fossa view of the superior vena cava. This method enhances the accuracy of catheter placement and assists in detecting thrombosis prior to insertion.
Key Study Components
Area of Science
- Clinical procedures
- Ultrasound guidance
- Vascular access techniques
Background
- Central venous catheters are essential for various medical treatments.
