Pro: manometry should routinely be used during central venous catheterization

Long-axis view for ultrasound-guided central venous catheter placement via the internal jugular vein

BACKGROUND

In modern practice, real-time ultrasound guidance is commonly employed for the placement of internal jugular vein catheters. With a new tool, such as ultrasound, comes the opportunity to refine and further optimize the ultrasound view during jugular vein catheterization. We describe jugular vein access techniques and use the long-axis view as an alternative to the commonly employed short-axis cross-section view for internal jugular vein access and cannulation.

CONCLUSION

The long-axis ultrasound-guided internal jugular vein approach for internal jugular vein cannulation is a useful alternative technique that can provide better needle tip and guidewire visualization than the more traditional short-axis ultrasound view.

Transient neurological deficit due to a misplacement of central venous catheter despite ultrasound guidance and ultrasound assistance

Central venous catheters (CVC) are frequently used in intensive care units (ICU), with a low incidence of complications, most of them being of mechanical origin and occurring during the insertion of the catheter. To avoid such complications, "ultrasound guidance" and "ultrasound assistance" are recommended. Nevertheless, even with trained and experienced physicians, mechanical complications of IJV access such as carotid punctures are still reported. We report the case of a 75-year-old woman, admitted into the ICU for CVC insertion due to impossibility of peripheral venous access. About 12 hours after the procedure, the patient presented a neurological deficit. The cervical and thoracic CT scan showed a transfixing path of the catheter from the left IJV into the left common carotid artery, with distal extremity of the catheter localized in the ascending aorta. The catheter was removed, and thereafter the neurological deficit immediately and definitely disappeared. Onset of a neurological deficit after CVC insertion into the IJV, regardless the time of occurrence after the procedure, should suggest complication due to the CVC insertion, even if procedure was uneventful and chest radiography confirmed the apparent accurate position of CVC.
