Management of iatrogenic inferior vena cava perforation with composite Wallstent-Z-stent technique.

Inferior vena cava rupture is uncommon but can occur as a result of trauma or catheterization and during venous interventions. We have described two cases of iatrogenic inferior vena cava perforation, with their successful management with bare metal stents (a composite Wallstent-Z-stent technique). This management strategy was possible owing to the unique properties of the venous system.
