The condition in which a blood clot forms in the deep veins of the body is referred to as Deep Vein Thrombosis (DVT). Clots form when blood thickens and clumps together. DVT occurs most often in the deep veins of the leg and thighs.
The causes of DVT include:
The symptoms occur in the affected leg and include:
Your doctor will diagnose DVT based on the medical history, physical examination, and test results.
The treatment options include conservative and surgical measures:
Medications: Your doctor may prescribe anti-coagulants (or blood thinners) that reduce the blood’s ability to clot. The role of these medications is to prevent the clot from getting bigger. Thrombolytic (or clot busters) to help break the clots are prescribed only in life threatening conditions.
Compression stockings are designed to help prevent the blood clots from developing in the deep veins of the leg. The stocking creates pressure and improves the blood flow in the legs and reduces the risk of developing blood clots.
Surgery is the last treatment option considered when the above conservative measures fail to reduce the symptoms of DVT. Surgery is the preferred treatment to remove large blood clots.
Untreated cases of DVT can lead to pulmonary embolism (PE). PE is a serious condition in which the blood clots break (known as embolus), travels through the blood circulation and lodges in the lung, blocking the blood flow.
Post- phlebitis syndrome (PPS) is a chronic complication of DVT and is characterized by swelling, skin discoloration, and pain in the affected leg.
