Lymphatic obstruction is a blockage of the lymph nodes -- vessels that drain fluid from tissues throughout the body and allow immune cells to travel where they are needed.
Lymphatic obstruction is also called lymphedema, which means swelling of the lymph passages. Lymph nodes may be enlarged for any reason.
Alternative NamesLymphedema
Causes, incidence, and risk factorsThere are many causes of lymphatic obstruction, including:
- Infections with parasites such as filariasis
- Injury (trauma)
- Radiation therapy
- Skin infections such as cellulitis (more common in obese patients)
- Surgery
- Tumors
In Western societies, one of the most common causes of lymphedema is removal of the breast (mastectomy) and underarm lymph tissue for Breast cancer. This can cause lymphedema of the arm in 10 - 15% of patients. This occurs because the lymphatic drainage of the arm passes through the armpit (axilla), and tissue in the axilla is removed during a mastectomy.
Rare forms of lymphedema that are present from birth (congenital) may result from problems in the development of the lymphatic vessels.
SymptomsThe main symptom is persistent (chronic) swelling, usually of the arm or leg.
Signs and testsThe doctor will perform a physical exam and ask questions about your medical history.
The following tests may be done:
- CT or MRI scan
- Lymphangiography
- Lymphoscintigraphy
Treatment for lymphedema includes:
- Compression (usually with multilayered bandages)
- Manual lymph drainage (MLD)
- Range of motion exercises
Manual lymph drainage is a light Massage Therapy technique in which the skin is moved in certain directions based on the structure of the lymphatic system. This helps the fluid and waste drain through the right channels.
Treatment also includes skin care to prevent injuries, infection, and skin breakdown, as well as light exercise and movement programs. Exercise should be carefully designed by a physical therapist. It should help drainage without leading to swelling from overexertion, which could make your condition worse.
Wearing compression stockings on the affected area or using a pneumatic compression pump on and off may be helpful. Your doctor and physical therapist will decide which compression methods are best.
Surgery is used in some cases, but it has limited success. The surgeon must have a lot of experience with this type of procedure. You will still need physical therapy after surgery to reduce lymphedema.
Types of surgery include:
- Liposuction
- Removal of abnormal lymphatic tissue
- Transplant of normal lymphatic tissues to areas with abnormal lymphatic drainage (less common)
Rarely, the surgeon will bypass abnormal lymph tissue using vein grafts. These procedures are not usually successful and are often done experimentally.
Expectations (prognosis)Lymphedema is a chronic disease that usually requires lifelong management. In some cases, lymphedema improves with time. However, some swelling is usually permanent.
ComplicationsIn addition to swelling, the most common complications include:
- Chronic wounds and ulcers
- Skin breakdown
You must be vigilant about skin care and hygiene. There is also a small risk of developing a lymph-tissue type of cancer.
Calling your health care providerSee your doctor if you have swelling of your arms, legs, or lymph nodes that does not go away.
PreventionSome surgeons are using a technique called sentinel lymph node dissection to prevent lymphedema from developing after surgery for breast cancer. However, this technique is not always appropriate or effective.

What is tissue swelling due to lymphatic obstruction?
Lymphatic obstruction is a blockage of the lymph vessels that drain fluid from tissues throughout the body and allow immune cells to travel where they are needed. Lymphatic obstruction may cause lymphedema, which means swelling due to a blockage of the lymph passages
Lymphatic obstruction can lead to edema?
Yes, lymphatic obstruction can lead to edema because it impairs the drainage of excess fluid from the tissues, causing fluid buildup and swelling. This can occur from conditions such as lymph node dissection, infection, or injury to the lymphatic vessels.
What is the consequences of lymphatic obstruction?
With obstruction of the lymphatic system, lymph will be unable to return to the systemic circulation (ie - the blood). Instead, this lymph builds up in the tissues causing swelling that can become extreme. Elephantiasis occurs when a microorganism causes obstruction of the lymphatics and results in grossly swollen appendages.
Is edema caused by lymphatic blockage?
Yes, edema can be caused by lymphatic blockage, which prevents lymph fluid from draining properly. This accumulation of fluid in tissues leads to swelling, particularly in the affected area. Conditions such as lymphedema result from damage or obstruction of lymphatic vessels, contributing to this fluid buildup. Other factors can also cause edema, but lymphatic obstruction is a significant contributor.
Is venous lymphatic obstruction of leg contagious?
No, venous lymphatic obstruction of the leg is not contagious. It is a medical condition that typically results from factors such as injury, surgery, infection, or underlying health issues like chronic venous insufficiency. It cannot be transmitted from one person to another.
When interstitial fluid collects as a result of obstruction it is called?
When interstitial fluid collects as a result of obstruction, it is called lymphedema. This condition can occur when the lymphatic system is unable to drain fluid properly, leading to swelling in the affected area. Treatment may involve manual lymphatic drainage, compression therapy, and exercise.
Is venous lyphatic obstruction contagious?
There is no evidence that Lymphatic obstruction disorder is contagious, however you still want to maintain a high level of hygeine since skin irritations can occur.æ The swelling caused by this disorder is usually permanent.
What is lymphedemia?
ANSWER Simply put, lymphedEMA is an abnormal accumulation of tissue fluid in the lymphatic system. There are different causes, including infections and impairment of the lymphatic vessels or excessive production of fluid caused by venous obstruction.

What is Chylous ascites a sign of?
Chylous ascites is a rare condition where milky white fluid rich in lymphatic fluid accumulates in the abdominal cavity. It can be a sign of underlying conditions such as lymphatic obstruction, trauma to the lymphatic system, or cancer. Further investigation is needed to determine the specific cause and appropriate treatment.
What causes secondary lymphangioma?
Secondary lymphangioma, also known as lymphatic malformation, typically arises from damage or obstruction of the lymphatic system due to injury, surgery, infection, or conditions such as cancer. This disruption leads to abnormal lymphatic vessel formation and can result in the accumulation of lymphatic fluid. Unlike primary lymphangiomas, which are congenital, secondary lymphangiomas develop as a response to these acquired factors. Treatment often focuses on managing symptoms and addressing the underlying cause.
What is dilation of a limph vessel?
Dilation of a lymph vessel refers to the abnormal enlargement or widening of a lymphatic vessel, which can occur due to various factors such as increased fluid pressure, obstruction, or inflammation. This condition can lead to impaired lymphatic drainage and may result in swelling (lymphedema) in the affected area. Dilation can also be associated with certain medical conditions, including lymphatic malformations or infections. Proper diagnosis and treatment are essential to manage any underlying issues and restore normal lymphatic function.
