Percutaneous antecubital transvenous cholangiography. A modified technique using a flexible needle.

A percutaneous antecubital transvenous cholangiography technique using a flexible 20 gauge needle is described. The porcedure was successful in 6 patients with obstructive jaundice but failed in 2 patients without bile duct dilatation. The authors feel that this technique is easier and safer than present transvenous methods. Modifications for the femoral approach and use of the technique in pediatric patients are described.
