Superior vena cava (SVC) syndrome is a collection of clinical signs and symptoms resulting from either partial or complete obstruction of blood flow through the SVC. This obstruction is most commonly a result of thrombus formation or tumor infiltration of the vessel wall Superior vena cava obstruction (SVCO) is characterized by facial and upper limb swelling, headache, and shortness of breath and usually is caused by advanced mediastinal malignancy. Conventional palliative treatment relies on radiotherapy, chemotherapy, and sometimes surgery Superior vena cava obstruction (SVCO) can occur from extrinsic compression, intrinsic stenosis, or thrombosis of the superior vena cava. Malignancies are the main cause and are considered an oncologic emergency. Superior vena cava syndrome (SVCS) refers to the clinical syndrome with symptoms that results from this obstruction Superior vena cava (SVC) syndrome is a clinical condition that occurs as a result of obstruction of the SVC, leading to interrupted venous return from the head, thorax, and upper extremities to the right atrium.

Superior vena cava obstruction Radiology Reference

  1. Superior vena cava obstruction refers to a partial or complete obstruction of the superior vena cava, typically in the context of cancer such as a cancer of the lung, metastatic cancer, or lymphoma. Obstruction can lead to enlarged veins in the head and neck, and may also cause breathlessness, cough, chest pain, and difficulty swallowing
  2. Superior vena cava obstruction (SVCO) This usually refers to a partial or complete obstruction of the SVC, often in the context of cancer (lung cancer, metastatic cancer, or lymphoma). Clinically this obstruction can lead to enlarged veins in the head and neck, and cause shortness of breath, cough, chest pain, and difficulty swallowing )
  3. Superior vena cava syndrome (SVCS) is a problem caused by partly blocked blood flow through the superior vena cava. This is the vein that carries blood away from the head, neck, arms, and upper chest. In most cases, the blockage develops slowly. In very rare cases, it happens fast and blocks the airway so a person can't breathe

  1. Treating superior vena cava obstruction. Treatment of superior vena cava obstruction aims to relieve the blockage. In the case of lung cancer, tumors will be targeted using chemotherapy, radiation therapy, surgery, and/or targeted therapies.Medications such as diuretics or steroids may be used to temporarily reduce the swelling
  2. The superior vena cava is a thin-walled, low pressure vessel which makes it vulnerable to compression. Superior vena cava obstruction can occur either due to external compression or from an occlusion within the vessel lumen itself. The most common cause of SVC obstruction is malignancy, typically from lung cancer, lymphoma, or metastatic disease
  3. There are several reasons why the superior vena cava may become obstructed, either partially or completely. The blockage may arise within the vein itself or external compression on the vein can also cause a blockage. If not treated immediately, superior vena cava syndrome can be lead to serious complications such a cerebral edema (brain swelling)

Superior vena cava endoprostheses have proven effective for treating benign causes of superior vena cava obstruction, even in the presence of a cardiac pacemaker. Endoprostheses are also used to bypass malignant obstructions of the superior vena cava because they do not preclude further oncologic treatment with surgery or chemotherapy, and they.
