B. Hematoma
C. Superficial vein thrombosis

Answer:
Superficial veins and are not accompanied by a corresponding artery. In the video and image, we only see a single vessel. The video shows a superficial vein with some echogenicity within it suggestive of a blood clot. The compression test is more reliable and shows a non-compressible superficial vein.
See video below of a normal fully compressible superficial vein. We generally do not use ultrasound to diagnose superficial vein thrombosis. If you are planning to insert an IV cannula and have doubt about the patency of a superficial vein, you may consider scanning the superficial vein with a high frequency linear ultrasound transducer and performing a compression test. The normal vein should collapse completely with compression force applied with the transducer.
