Phlegmasia alba dolens

Phlegmasia alba dolens (PAD) is a rare but severe form of deep vein thrombosis (DVT) which is characterized by swelling and white discoloration of the leg. It is also known as "milk leg" or "white leg". PAD is a medical emergency that requires immediate treatment.

Signs and Symptoms

The primary symptoms of PAD are severe pain and swelling in the leg. The affected leg may also appear pale or white, hence the name "white leg". Other symptoms may include fever, rapid heart rate, and in severe cases, shock.

Causes

PAD is caused by a large blood clot that blocks blood flow in the veins of the leg. This can occur as a result of surgery, injury, or prolonged bed rest. It can also occur in women during pregnancy or in the postpartum period.

Diagnosis

Diagnosis of PAD is typically made based on the patient's symptoms and physical examination. Imaging tests such as ultrasound or venography may be used to confirm the diagnosis and locate the clot.

Treatment

Treatment for PAD involves removing or dissolving the blood clot. This can be done with anticoagulant medications, thrombolytic therapy, or in severe cases, surgery. In addition to treating the clot, treatment may also involve managing any underlying conditions that contributed to the clot's formation.

Prognosis

With prompt treatment, the prognosis for PAD is generally good. However, if left untreated, PAD can lead to serious complications such as pulmonary embolism or post-thrombotic syndrome.
