What is Superficial Venous Thrombosis (SVT)?

Jason Henrie, APRN

Superficial venous thrombosis (SVT) is an attack of blood clots in the veins that are just under the skin surface within the fat layers. SVT is something that can reoccur and is a common medical issue. The percentage of patients affected by SVT is unknown and it affects both women and men equally. SVT produces an area of redness and warmth on the skin surface with associated pain and firm lumpiness under the skin. Swelling can be seen but is not always present. Ultrasound and physical findings are used to diagnose SVT.

Etiology

The cause of SVT is not always known or easy to find. A common cause is recent injury or trauma to the area affected. There is a large number of patients who have a hypercoagulable state or a clotting problem. Identifying the clotting problem may change how your physician may treat the SVT.

Treatment

Mild pain medications such as Tylenol and Ibuprofen will help with the discomfort from the SVT. Warm compresses over the affected area and the use of compression stockings will also help. If the SVT is in the upper thigh or near the deep veins more aggressive treatment may be needed such as anticoagulation.

Conclusion

Most cases of SVT go unnoticed or are not taken seriously and resolve on their own within in few weeks. Treatment is most often conservative if found by your physician and the SVT will eventually resolve with time.
