Acute Thrombus in the Internal Jugular Vein

# data[].attributes.body
When newly formed clotted blood is within the vein. Typically, the blood clot is less than 14 days old. Most commonly seen in the superficial veins. If walls do not coapt while compressing, then thrombus should always be suspected.

# data[].attributes.attachment_caption
Thrombus sits in the center of the lumen in transverse and longitudinal. Color doppler is presented and shows blood flows around the thrombus.

# data[].attributes.body
Characteristics to distinguish while scanning are:
-Dilated walls
-Spongy texture within the lumen
-Material is poorly attached to the wall of the vein
-Lightly echogenic and hypoechoic appearance

# data[].attributes.body
When clotted blood has been present for a period of time for several weeks or months. The clot will begin to harden and scar the vein. Furthermore, the vein will appear much smaller and not allow blood to flow through the vein effectively.

Rigid texture (A) and constricted vessel wall (B). Overall, echogenic material is attached to vessel walls.

# data[].attributes.body
The appearance of chronic thrombosis may be visualized as:
-Brightly echogenic or hyperechoic
-Attached to the vessel wall
-Contracted (smaller) vein
-Rigid texture

Primary treatment is through anticoagulation. These are medicines that help prevent blood from clotting. Some of these medicines include:
-Warfarin
-Aspirin
-Heparin

Other forms of treatment may also be catheter removals, thrombolytic therapy, and surgical compression of thoracic inlet with or without venous reconstruction.
