Old probe, new method: Y-shape visualization of central veins using endocavitary transducer via omoclavicular acoustic window

Ultrasound-guided supraclavicular brachiocephalic vein catheterization in children: Syringe-free in-plane technique with micro-convex probe

“…The needle is advanced within the brachiocephalic vein without getting close to the vessel walls and the guidewire enters directly in the brachiocephalic vein and proceeds forward without changing its direction. [7][8][9][10] The lesser footprint of the micro-convex US probe is another advantage, which makes it more suitable to use for neonates and infants. The operator finds a larger area for manipulations and redirections of the needle when the micro-convex US probe is used.…”

“…Our technique is based on visualization of the subclavian, jugular, and brachiocephalic veins together as a Y shape using micro-convex US probe. 9 We also used a novel syringe-free technique, which has been recently described by Matias et al 7 In order to provide a syringefree introducer set, the needle should be attached to the plastic cover of the guidewire instead of a syringe ( Figure 1(a)). We used 3-, 4-, and 5-Fr-sized pediatric catheters (Certofix Trio Paed, Braun, Melsungen, Germany) in our patients.…”

“…Its small footprint is an advantage, which may be potentially efficient in pediatric patients for facilitating the needle advancement and redirections during the cannulation procedure. 9,10 We would like to present our novel supraclavicular approach for brachiocephalic vein cannulation with US guidance in pediatric patients. We combined the syringe-free technique and the endocavity micro-convex US probe for cannulating the brachiocephalic vein.…”

Where is the Guidewire? Confirmation of Central Catheter Placement in the Brachiocephalic Vein Using Y-shape Visualization by Ultrasound

“…Endocavity micro-convex probes provide sufficient resolution for both superficial tissues, such as the internal jugular vein (IJV), and deep tissues, such as the brachiocephalic vein, with a higher tissue penetration. With this technique, the internal jugular vein, subclavian vein (SV), and brachiocephalic vein (BV) can be visualized together as a Y-shape [4-5]. The guidewire can be advanced within the brachiocephalic vein by real-time visualization and the catheter position in the BV can be visualized as well [6-7].…”
