Patient's Query

Hi doctor,

I have consulted a vascular radiologist for calf edema. There was no discomfort or redness. I am in my perimenopausal period.

These were the findings.

Technique: Duplex ultrasound of the left lower extremity venous system was performed with the patient in a standing position and using manual compression for flow augmentation to assess for superficial and deep venous insufficiency. Images were obtained using 2D grayscale (B-mode) imaging, Doppler spectral analysis, and color flow Doppler.

Findings:

Left Lower Extremity Deep System: Common Femoral Vein: Patent and compressible; Antegrade flow; Reflux duration: 0 seconds Saphenofemoral Junction: Patent and compressible; Antegrade flow Profunda Femoral Vein: Patent and compressible; Antegrade flow Femoral Vein Upper: Patent and compressible; Antegrade flow Mid: Patent and compressible; Antegrade flow; Reflux duration: 0 seconds Lower: Patent and compressible; Antegrade flow Popliteal Vein: Patent and compressible; Antegrade flow; Reflux duration: 0 seconds Superficial System: Great Saphenous Vein Saphenofemoral Junction: 6.8 mm; Reflux duration: 0 seconds Upper Thigh: 5.4 mm; Reflux duration: 0 seconds Mid Thigh: 4.0 mm; Reflux duration: 0 seconds Lower Thigh: 4.0 mm; Reflux duration: 0 seconds Upper Calf: 4.1 mm; Reflux duration: 4 seconds Lower Calf: 2.5 mm; Reflux duration: 0 seconds Small Saphenous Vein Saphenopopliteal Junction: does not join popliteal vein Upper Calf: 2.0 mm; Reflux duration: 0 seconds Lower Calf: 2.7 mm; Reflux duration: 0 seconds

The doctor feels the targeted swelling is caused by a vein, though this is not common. However, he said the vein might still be the cause.

Since I suffer from medical anxiety, I would like to know if this doppler ultrasound shows lipoedema? I am confident he overlooked the lipoedema.

Hello,

Welcome to icliniq.com.

I understand your concern.

From your statement, I understood that you have been experiencing leg swelling beneath the knee.

A venous Doppler ultrasonography is required for the diagnosis of lipoedema. Lipoedema has many characteristics of venous insufficiency, which may be validated with venous Doppler ultrasonography.

On the other hand, Lymphedema may be detected with Doppler ultrasonography and Lymphoscintigraphy.

Lipoedema is often symmetrical, affecting both sides of the body due to fat distribution.

Other medical diseases that might induce comparable clinical symptoms include primary valve deficit, protein C and S deficiency, popliteal cyst, deep vein thrombosis, post-surgical infection, leg ulcer or ischemia, and so on.

There is no need to be concerned because nothing further is revealed in the findings. Lipoedema is a benign illness with a good prognosis. However, it may be something else because venous Doppler ultrasound does not prove it.

Again, FNAC (fine needle aspiration cytology) or biopsy can be used to determine the underlying pathology of the swelling in the leg under the knee, after which you can begin therapy.

Patient's Query

Thank you doctor for your concern,

I had taken another ultrasound the day before, and the results revealed that there were no lumps, no fluid, and the soft tissue was normal, but there was adipose tissue buildup surrounding that spot.

Hello,

Welcome back to icliniq.com.

I read your query and can understand your concern.

According to the ultrasound findings, there is adipose tissue deposition around the swelling, suggesting that it is lipoedema. Women with lipoedema frequently have psychosocial concerns such as anxiety and depression, which can lead to eating disorders like binge eating. Lipoedema is a chronic benign condition. According to some clinical studies, 85 percent of lipoedema patients are obese. According to certain research, anxiety is also linked to lipoedema.

When the lymphatic system is affected, lipoedema might progress to lymphoedema.

It usually does not require treatment if there are no accompanying issues, such as pain.

Lipoedema can be effectively treated by circumferential liposuction.

The most significant test for diagnosing lipoedema is venous Doppler ultrasonography. Before taking any medications, consult your doctor.

Same symptoms don't mean you have the same problem. Consult a doctor now!
