Painful thigh bruise

Introduction When the iliac crest and femoral vein thrombosis, extensively involving the intramuscular venous plexus, the iliac vein and its collaterals are all blocked by the thrombus, the lower extremity is highly edematous. Due to severe venous return disorder, severe congestion, clinical manifestations of severe pain, the skin of the affected limb is purpura, known as painful femoral bruises. The clinical manifestations are severe pain, the skin of the affected limb is purpura, often accompanied by arterial spasm, the lower extremity arterial pulsation weakens or disappears, the skin temperature decreases, and then the high circulation disorder occurs, which becomes the emergency state of the lower extremity DVT, the systemic reaction is large, and the shock is easy to occur. And wet gangrene of the lower extremities.

Cause

Venous thrombosis is a common vascular disease of the extremities. In recent years, the incidence of this disease has increased year by year. According to reports, there are 250,000 to 500,000 patients with venous thromboembolic disease every year in the United States; the lower extremity deep venous insufficiency in the UK accounts for 0.5% of the population, most of which is the sequela of deep venous thrombosis of the lower extremities. Domestic deep vein thrombosis has also increased year by year. Since the 19th century, Virchow first proposed three major factors of venous thrombosis (high blood coagulation, blood flow stagnation and wall damage), which has been recognized by the medical community for nearly a hundred years. The disease occurs in the lower limbs, after thrombosis, the distal venous hypertension of the thrombus, which causes limb swelling, pain and superficial vein dilatation or varicose and other clinical manifestations. Severe cases can also affect arterial blood supply, and damage the venous valve, leaving permanent deep venous insufficiency of the lower extremities to affect the quality of life.

The clinical manifestations are severe pain, the skin of the affected limb is purpura, often accompanied by arterial spasm, the lower extremity arterial pulsation weakens or disappears, the skin temperature decreases, and then the high circulation disorder occurs, which becomes the emergency state of the lower extremity DVT, the systemic reaction is large, and the shock is easy to occur. And wet gangrene of the lower extremities.

Cardiovascular angiography is one of the important means of diagnosing cardiovascular disease.

General radiography examination General film examination can be used to shoot the skull, chest, abdominal plain, bones and joints of the limbs. The film plays an important role in the diagnosis work, and has the following advantages compared with the perspective:

1. The image of the part to be inspected is permanently retained on the film for analysis, discussion and review.

2. Can be saved as scientific research materials.

3. The film can show the fine structure, such as the early source of more than 2mm is more clear than the perspective.

4. The film can check the thick part of the human body and make the patient receive less X-rays.

Differential diagnosis

Painful white swelling: When the lower extremity deep vein acute embolism, the lower extremity edema reaches the highest level within a few hours, the swelling is concave and high tension, and the obstruction mainly occurs in the femoral vein system. When the infection is combined, the artery is stimulated to continue to sputum, showing swelling of the whole limb, pale skin and subcutaneous reticular venous dilation, called Phlegmasia Alba Dolens.
