Cannula-Assisted, Transabdominal Ultrasound-Guided Inferior Vena Cava Recanalization in Inferior Vena Cava Occlusion

We describe a novel technique for facilitating recanalization of intrahepatic inferior vena cava (IVC) via the transjugular approach in patients with short segmental hepatic IVC occlusion, where a transjugular liver biopsy cannula provides additional support to the catheter-wire combination and trans-abdominal ultrasound helps in positioning the tip of the cannula at the stump of suprahepatic IVC.
