What Is an Upper Extremity Deep Vein Thrombosis?

A deep vein thrombosis (DVT) occurs when a blood clot forms in a vein deep inside of your body. Blood clots can form when blood thickens and clumps together. If a blood clot does form, it’s possible for it to break off and travel through your bloodstream.

Sometimes, a clot can travel to your lungs and restrict blood flow. This is known as a pulmonary embolism (PE). Blood clots that form in your calves or pelvis are more likely to break off and cause a PE than clots in other areas.

If you’ve ever had to sit still for a long time, such as during a long airline flight, you may have heard about the risk of developing a blood clot in your leg and what to do about it. In different circumstances, it’s possible to develop this type of clot above your waist.

Upper extremity DVT (UEDVT) can appear in your neck or arms and travel to your lungs. This type of DVT can also lead to a PE.

About 10 percent of all DVTs occur in the upper extremity. UEDVTs affect about 3 out of every 100,000 people.
