What finding is associated with chronic SVC syndrome?

• A. Collateral vessels over chest/abdomen
• B. Enlarged spleen
• C. Ascites
• D. Renal cysts

Answer: (A)

Chronic obstruction of the superior vena cava forces blood from the upper body to find alternative routes back to the heart, so collateral venous channels develop to bypass the blockage. These collaterals commonly appear on the chest wall and upper abdomen as prominent, dilated veins, which is the classic finding in chronic SVC syndrome. Enlarged spleen, ascites, and renal cysts are not direct consequences of SVC obstruction; they relate to other conditions such as portal hypertension, liver disease, or renal pathology, and thus do not fit the typical pattern of collateral chest/abdominal venous dilation associated with this syndrome.
