Complications

Complications of DVT can include:

• Pulmonary embolism (PE). PE is a potentially life-threatening complication associated with DVT. It occurs when a blood vessel in your lung becomes blocked by a blood clot (thrombus) that travels to your lung from another part of your body, usually your leg.

  It's important to get immediate medical help if you have signs and symptoms of PE. Sudden shortness of breath, chest pain while inhaling or coughing, rapid breathing, rapid pulse, feeling faint or fainting, and coughing up blood may occur with a PE.

• Postphlebitic syndrome. Damage to your veins from the blood clot reduces blood flow in the affected areas, causing leg pain and swelling, skin discoloration and skin sores.
• Treatment complications. Complications may result from blood thinners used to treat DVTs. Bleeding (hemorrhage) is a worrisome side effect of blood thinners. It's important to have regular blood tests while taking such medications.
