Embolism and thrombosis of superior vena cava (SVC) are two conditions that affect the flow of blood to the upper body. The superior vena cava is a large vein that carries deoxygenated blood from the upper body to the heart. Any blockage in this vein can lead to a disruption in the blood flow, causing severe health issues.
Embolism of SVC: Embolism of SVC occurs when a blood clot or other foreign material travels through the bloodstream and gets lodged in the SVC. The blockage can occur anywhere along the vein, leading to a reduction in blood flow to the head, neck, and upper extremities. Common causes of embolism of SVC include deep vein thrombosis (DVT) in the upper extremities, cancer, and catheterization procedures.
Thrombosis of SVC: Thrombosis of SVC occurs when a blood clot forms inside the vein, leading to a blockage in blood flow. The condition is usually caused by a combination of factors such as cancer, central venous catheterization, and hypercoagulable states. Symptoms of thrombosis of SVC include swelling, pain, and discoloration of the affected area.
Diagnosis of embolism and thrombosis of SVC typically involves a physical exam, imaging tests such as CT scans, MRIs or ultrasound, and blood tests. Treatment options for both conditions include anticoagulant medication to dissolve the blood clot, thrombolytic therapy to break up the clot, and surgical removal of the clot in severe cases. In some cases, a stent may be placed in the SVC to keep it open and improve blood flow.
There are several steps you can take to reduce your risk of developing embolism and thrombosis of SVC. These include:
