Catheter malposition following supraclavicular approach for subclavian vein catheterisation--case reports.

The supraclavicular approach of subclavian vein catheterization is associated with the lowest incidence of malposition. We report two cases of unusual malpositions seen during central venous cathelerization of subclavian vein via supraclavicular approach. Literature search did not reveal such malpositions. The possible cause for the malposition and method to prevent it is discussed.
