What are the symptoms of lymphatic duct obstruction?

Lymph is an important organ for us to resist external pathogens. If the lymphatic vessels are blocked, it will actually have a great impact on the body's immunity. If there are symptoms of lymphatic vessel blockage, the patient's lymphatic vessels will enlarge, there will be extralymphatic infiltration, and lymphatic reflux. Lymphatic vessel blockage needs to be treated promptly to avoid affecting the health of the body.

Radiographic findings

Lymphangiography can be used to determine whether lymphatic vessel obstruction occurs and to identify the site of obstruction, which is very helpful for clinical diagnosis and treatment. When analyzing the results of lymphangiography, attention must be paid to the number, course, contour, diameter and valve condition of the lymphatic vessels. The common X-ray signs of lymphatic vessel obstruction are summarized as follows.

Enlarged lymphatic vessels:

The lymphatic vessels were shown to be widened and twisted.

Lymphatic congestion:

Iodized oil may remain in the lymphatic vessels for 24 hours or longer after injection.

Lymphatic extravasation:

Due to the increased pressure in the lymphatic vessels, the lymphatic vessels rupture. When lymph enters the interstitial space, extravasation of contrast agent can be seen during angiography. Lymph fluid extravasates into the sheaths around blood vessels and nerves, and the contrast agent can outline the blood vessels. Lymph fluid breaks into the abdominal cavity, intestinal tract, urinary tract, and thoracic cavity, which can show signs of contrast agent entering the abdominal cavity, intestinal tract, urinary tract, and thoracic cavity, respectively.

Decreased or absent number of lymphatic vessels:

It is common in limb lymphedema, which is manifested by a decrease in the number of lymphatic vessels, often accompanied by enlargement, distortion and extravasation of the lymphatic vessels.

Lymphatic reflux:

It manifests as reverse filling of lymphatic vessels. If retrograde filling of lymphatic vessels around pelvic organs is found, it indicates obstruction of the common iliac lymph nodes or lumbar lymph trunk on that side.

Lymphatic collateral pathways:

The emergence of lymphatic collateral pathways is one of the most common signs of lymphatic obstruction and is also the main way the body uses to overcome obstruction. There are two basic forms of lymphatic lateral communication pathways.

① Lymphatic and venous anastomosis: In the area of ​​lymphatic obstruction, contrast agent can be seen in the vein. This proves the existence of lymphovenous anastomosis. Lymphatic angiography often does not allow direct visualization of the pathways.

②Lymphatic and lymphatic anastomosis: It is the most common collateral pathway, similar to the collateral circulation produced after vascular occlusion. For example, when the lumbar lymph nodes are completely blocked, the contrast agent is shunted to the opposite side through the communicating lymphatic vessels at the aortic bifurcation, showing the contralateral lumbar lymph trunk. For example, if the obstruction is located in the groin or subiliac region, extensive subcutaneous collateral lymphatic pathways can be shown in the thigh perineum, external genitalia, and anterior abdominal wall.

Complete the first lymphatic detoxification in 30 seconds

1. Stimulate the muscles around the lymph nodes

Put the four fingers except the thumb into the armpit, and use the thumb and other four fingers to pinch the armpit muscles and pull them upwards or knead them to stimulate the muscles.

2. Find lymph nodes

Raise your arm and touch the slightly raised part of your armpit, and place four fingers in front of the raised part with this as the center. Press gently and you will find small lumps the size of beans, which are where the lymph nodes are concentrated.

3. Relax the concentrated lymphatic muscles

Stretch your arms back to stimulate the muscles behind the bulge under your armpits. Stack three fingers and press hard on this area for 5 seconds, then slowly release them, and repeat several times.

4. Cleanse toxins

Use your thumb and index finger to pinch your upper arm, push from the elbow to the armpit, and continue to press down with your index and middle fingers as the main force points to promote blood flow to the armpit.

5. Accelerate detoxification

After the last few steps, your arms have relaxed. Now, hold your arms with your hands and press down to help detoxify. Don't just use your thumb and index finger to apply force, also use the muscle strength of the base of the thumb to apply pressure.
