Does TB cause SVC obstruction?

SVC obstruction, although more commonly associated with malignancies, is a reported complication of tuberculosis.

What is the most common cause of superior vena cava syndrome?

SVCS is most often seen in people with cancer. It’s most common with lung cancer or non-Hodgkin lymphoma. Far less often, it’s linked to other causes, such as infection or a blood clot in the SVC caused by an implanted medical device. The device may be a central catheter, dialysis catheter, or pacemaker wire.

Can TB cause SVC syndrome?

Tuberculosis is currently an uncommon cause of SVC syndrome. The rarity of SVC syndrome may cause delays in diagnosis and treatment, and inadequate diagnostic techniques can result in a substantial increase in morbidity and mortality.

What happens when the SVC is blocked?

Superior vena cava syndrome (SVCS) is a group of symptoms that occur when there is pressure on the superior vena cava, or it is partially blocked and blood can’t flow back to the heart normally. This causes more pressure in the veins and face, which leads to a buildup of fluid or swelling.

How do you test for superior vena cava syndrome?

The following tests will help your doctor diagnose SVCS.

  1. X-rays of your chest or the vein. X-rays of a vein use dye to help the vein show up clearly.
  2. CT scan, also called computed tomography.
  3. MRI, also called magnetic resonance imaging.
  4. Ultrasound.

What are the complications of superior vena cava syndrome?

Patients with SVCS can, rarely, develop life-threatening complications such as cerebral edema, causing headache, dizziness, confusion, and eventually coma or compromised hemodynamics, if SVC obstruction impairs venous return to the right atrium.

Is SVC syndrome curable?

Superior vena cava syndrome itself is very treatable, and symptoms are usually greatly improved within the first month of treatment. However, because the majority of cases are caused by cancer, the overall outlook will depend on the type and stage of the cancer involved.
