Effectiveness of sharp recanalization of superior vena cava-right atrium junction occlusion

Figure 1 A 25-yr-old female with a sharp recanalization procedure due to superior vena cava obstruction. A: Before sharp recanalization, angiography showed superior vena cava occlusion; B and C: After puncturing the occluded segment (B), the patient complicated with acute pericardial tamponade (C); D: Sharp recanalization succeeded at the second surgery; E: Percutaneous transluminal angioplasty and percutaneous transluminal stenting were performed; F: Venous blood of the superior vena cava.
