| Summary: | Despite the level of skill of the operator and the use of ultrasound guidance, central venous catheter
(CVC) placement can result in CVC malpositioning, an unintended placement of the catheter tip in
an inadequate vessel. CVC malpositioning is not a complication of central line insertion; however,
undiagnosed CVC malpositioning can be associated with significant morbidity and mortality. The
objectives of this review were to describe factors associated with intravascular malpositioning of
CVCs inserted via the neck and chest and to offer ways of preventing, identifying, and correcting
such malpositioning. A literature search of PubMed, Cochrane Library, and MD Consult was
performed in June 2014. By searching for “Central line malposition” and then for “Central venous
catheters intravascular malposition,” we found 178 articles written in English. Of those, we found
that 39 were relevant to our objectives and included them in our review. According to those articles,
intravascular CVC malpositioning is associated with the presence of congenital and acquired
anatomical variants, catheter insertion in left thoracic venous system, inappropriate bevel orientation
upon needle insertion, and patient’s body habitus variants. Although plain chest radiography is
the standard imaging modality for confirming catheter tip location, signs and symptoms of CVC
malpositioning even in presence of normal or inconclusive conventional radiography findings should
prompt the use of additional diagnostic methods to confirm or rule out CVC malpositioning. With very
few exceptions, the recommendation in cases of intravascular CVC malpositioning is to remove and
relocate the catheter. Knowing the mechanisms of CVC malpositioning and how to prevent, identify,
and correct CVC malpositioning could decrease harm to patients with this condition. |
