Deep Vein Thrombosis (DVT) occurs when blood thickens in a clump to form a blood clot in the deep veins. Typically, the blood clots form in the lower leg, thigh or pelvis, but can also occur in the arm or shoulder. DVT’s can happen to anyone and may lead to serious illness, disability and in some cases death. Although DVT’s are underdiagnosed and serious, they are usually preventable and treatable if discovered early.
If you are concerned by a swollen extremity, a comprehensive evaluation that includes an ultrasound must be completed to properly detect blockages or blood clots in deep veins. A blood test, MRI, CT scan or contrast venography may also be used to diagnose blood clots.
