Emguidewire's Podcast

Join the EMGuideWire team as they discuss Superior Vena Cava Syndrome! Shownotes: Definition: Any condition leading to obstruction of blood flow through the SVC Pathophysiology: Pathology in adjacent anatomy (lung, lymph node, thymus, mediastinum) or within the SVC itself obstructs venous return to the right atrium. As the SVC is compressed, venous collaterals form alternative pathways returning blood to the right atrium which can dilate over several weeks. As a result, upper body venous pressure increases, which in extreme cases lead to airway congestion and venous cerebrovascular congestion and edema. Hemomdynamic compromise is most often by direct compression of the heart, not from SVC obstruction. Risk factors: Indwelling device through the SVC (Central line, dialysis catheter, pacemaker) Lung cancer Lymphoma Thymoma Presentation: Signs – plethoric appearance, dilated neck and chest veins, swollen face/neck/chest Symptoms – congestive symptoms (head fullness, swelling), cardiopulmonary symptoms (ch
