Micropuncture needles combined with ultrasound guidance for unusual central venous cannulation: desperate times call for desperate measures--a new trick for old anesthesiologists

Abstract

Central vascular access can be a very challenging task in patients with skeletal deformities such as ankylosing spondylitis, kyphosis, and chin-on-chest deformity. The use of traditional methods of accessing the central venous circulation in these patients can require multiple attempts and may lead to significant complications such as bleeding, pneumothorax, and vascular injury. Ultrasound-guided central venous access has become a very common procedure in the United States and Europe; its efficacy and safety have been demonstrated, and together with the use of micropuncture needles, the technique can facilitate central venous access in complicated cases.
