Sharp Recanalization with the Upstream GoBack Catheter for Chronic Occlusive Ilio-Caval Thrombosis.

Recanalization of chronic iliofemoral deep vein thrombosis is indicated to reduce symptoms and improve quality of life. However, recanalization is dependent on the ability to cross chronic obstructions. We present a case of chronically thrombosed inferior vena cava and common iliac veins that failed conventional crossing techniques but were successfully recanalized using the recently approved Upstream GoBack Crossing Catheter.
