Possible Complications of Superficial Thrombophlebitis
Superficial thrombophlebitis usually does not result in complications due to the absence of surrounding muscles in the affected veins. However, with deep vein thrombosis (DVT), the presence of surrounding muscles increases the risk of complications. The muscles can exert pressure on a blood clot, causing it to dislodge. If the clot travels to the lungs, it can lead to a life-threatening condition called pulmonary embolism, where an artery is blocked by the clot.
Individuals who have experienced DVT in the past are also at risk of developing postphlebitic or post-thrombotic syndrome. This syndrome is characterized by extreme pain, which can be disabling. In addition to the pain, swelling and a general feeling of heaviness are common symptoms experienced by those with postphlebitic syndrome.
Diagnosing Thrombophlebitis
When it comes to diagnosing or confirming the presence of thrombophlebitis, doctors have several options at their disposal. Initially, they may examine veins that are visible near the surface of the skin. If a definitive diagnosis cannot be made, an ultrasound may be performed. This diagnostic tool not only effectively detects thrombophlebitis but also helps differentiate between superficial and deep vein thrombosis (DVT).
Alternatively, some physicians may opt for a blood test to check for elevated levels of D dimer. Higher levels of this protein indicate the presence of a blood clot. Additionally, this test can also identify individuals who are prone to recurrent episodes of thrombophlebitis.
