Phlegmasia

From WikiMD's Wellnesspedia

Phlegmasia Cerulea Dolens is a severe form of deep vein thrombosis (DVT) that leads to an acute blockage of venous return and is characterized by significant swelling, pain, and a bluish discoloration of the affected limb, often the leg. This condition is considered a medical emergency due to the risk of venous gangrene and potential pulmonary embolism.

Etiology[edit | edit source]

Phlegmasia Cerulea Dolens primarily results from extensive thrombosis in the major deep veins of the lower extremity, which can be precipitated by conditions that increase the risk of thrombosis. These include, but are not limited to, cancer, prolonged periods of immobility, coagulopathy, surgery, and pregnancy. The massive thrombosis obstructs venous outflow, leading to increased venous pressure, severe edema, and impaired arterial inflow.

Symptoms and Diagnosis[edit | edit source]

The hallmark symptoms of Phlegmasia Cerulea Dolens include:

  • Severe pain and swelling in the affected limb
  • A pale to bluish discoloration (cyanosis)
  • Possible development of blisters or skin ulcers

Diagnosis is primarily clinical but can be supported by imaging studies such as ultrasound, which can visualize the thrombus, and venography. Other diagnostic tools might include MRI or CT scans to assess the extent of the thrombosis and involvement of the iliac veins.

Treatment[edit | edit source]

Immediate treatment is critical to prevent further complications and may include:

  • Anticoagulation therapy to prevent clot enlargement
  • Thrombolytic therapy to dissolve the existing clot
  • Catheter-directed thrombolysis for more direct clot removal
  • Surgical thrombectomy in severe cases where other treatments are not viable
  • Elevation of the affected limb and compression therapy to reduce swelling

In some cases, the placement of an inferior vena cava filter may be necessary to prevent pulmonary embolism, especially in patients who cannot be anticoagulated.

Complications[edit | edit source]

Without prompt treatment, Phlegmasia Cerulea Dolens can lead to venous gangrene, which may necessitate amputation of the affected limb. Pulmonary embolism is another serious complication that can be life-threatening.

Prognosis[edit | edit source]

The prognosis for Phlegmasia Cerulea Dolens varies depending on the speed of diagnosis and treatment initiation. Early and aggressive treatment improves outcomes significantly, but the condition can be fatal if not treated promptly.

Prevention[edit | edit source]

Preventive measures for Phlegmasia Cerulea Dolens focus on the underlying risk factors for deep vein thrombosis, including:

  • Regular movement and exercise, especially during long periods of immobility (e.g., after surgery or during long flights)
  • Use of anticoagulants in high-risk individuals
  • Compression stockings to improve venous return
