Superior Vena Cava

Syndrome Superior Vena Cava Syndrome (SVCS) is a rare and serious condition caused by a blockage of the superior vena cava - the major vein that carries blood from the head, neck, arms, and chest to the heart. Symptoms may include swelling in the face, neck, and arms, difficulty breathing, dizziness, and low blood pressure. Sudden and rapid weight gain can also occur. Treatment usually involves angioplasty or thrombolytic therapy to open the blocked vein, as well as medications to reduce symptoms. SVCS not only affects the quality of life of the patient, but can be life-threatening if left untreated. Early diagnosis is critical to ensure the best outcomes and prognosis.
