Successful treatment of recurrent superior vena cava syndrome due to pulmonary adenocarcinoma using intravascular ultrasound.

ABSTRACT: Patients with malignant diseases may develop symptoms of superior vena cava syndrome (SVCS) quickly because rapid tumor growth does not allow adequate time to develop collateral blood flow. Therefore, malignant SVCS is a medical emergency associated with neurological or pharyngeal-laryngeal signs. Recently, interventional endovascular treatment (EVT) has achieved acceptable results. We describe the case of a 55-year-old woman with pulmonary adenocarcinoma and laryngeal edema. In the first EVT, bare-metal-stent was implanted into the SVCS with intravascular ultrasound (IVUS) guidance. The IVUS showed insufficient stent-mid expansion. We did not use additional ballooning because of the risk of superior vena cava (SVC) rupture. Three months later, the SVCS recurred. A second EVT was performed
