Venous Ultrasound An Overview
A venous ultrasound is a non-invasive examination that uses sound waves to produce images of the veins in the body. Venous ultrasound imaging can help physicians diagnose and treat various types of medical conditions.
Why is a venous ultrasound performed?
A venous ultrasound is commonly performed to search for blood clots in the legs, a condition often referred to as deep vein thrombosis (DVT). When clots break free, it can travel to the lungs, heart, or brain. Patients with deep vein thrombosis may have an increased risk of stroke, heart attack, and pulmonary embolism.
A venous ultrasound may also be performed to:
- Aid in the placement of a catheter
- Identify damaged vein or abnormal blood flow
- Asses the condition of a vein after treatment
Venous Ultrasound What to Expect
How To Prepare
You should wear comfortable clothing for your examination. During your procedure, you may be asked to change into a gown. In some cases, patients may be asked to fast 8 hours before their ultrasound.
What To Expect
A venous ultrasound is painless, non-invasive examinations. In most cases, you will be positioned face up on the exam table. Your technician may ask you to move, tilt, or roll over throughout your examinations to produce various angles for your images.
A gel is applied to the designated area, and your sonographer will carefully glide the transducer over the designated area. A venous ultrasound may last up to an hour. Once the examination is complete, your physician will analyze the results and determine if further testing or treatment is required.
