Transjugular liver access cannula as a guiding instrument for the recanalization of chronic venous occlusions.

Background: Chronic venous occlusions can result in debilitating symptoms and can be refractory to standard methods of venous recanalization because of the formation of dense fibrous tissue. A transjugular liver access cannula can be incorporated into recanalization efforts to treat such refractory cases. This report describes our experience using the transjugular liver access cannula technique in nine patients.
