Contraindications to Manual Lymph Drainage: Insights from Foldi’s Textbook of Lymphology (part 2 of 3)

Last month, we began a series on contraindications to MLD. This post will continue that topic, citing a few more contraindications.

3. Heart Failure

Patients with heart failure are at risk for fluid overload, and MLD could further strain their cardiovascular system. The technique’s effects on fluid mobilization may overwhelm the heart’s ability to manage the increased fluid load. Foldi underscores the importance of careful evaluation of a patient’s cardiac function before initiating MLD, especially in those with advanced heart conditions. MLD is not appropriate if heart failure isn’t controlled. And it’s not appropriate if the sole reason for swelling is heart failure as that is a medical condition requiring medical intervention (not lymphedema). Patients with combined edema (from heart failure or other organ dysfunction) and lymphedema require extra caution.

4. Renal Insufficiency

Patients suffering from severe renal insufficiency or kidney failure may experience difficulties in fluid regulation. In such cases, MLD could cause fluid retention and exacerbate symptoms like edema or ascites (according to Ai). (My position is that MLD increases lymphatic flow & ultimately cardiovascular return & renal load. But MLD is primarily not done as it would be of no benefit because lymph vessels are already working at maximum capacity due to the dynamic nature of the edema.) Patients with impaired kidney function should be closely monitored, and MLD should be avoided or used with extreme caution in individuals with compromised renal status. Again, patients with combined edema (from renal disease or other organ dysfunction) and lymphedema require extra caution.

5. Thromboembolic Disorders

Deep vein thrombosis (DVT) or other thromboembolic disorders are a significant contraindication for MLD. Manual lymph drainage can increase blood and lymphatic flow, potentially dislodging clots and causing a pulmonary embolism (PE) or other complications. Foldi’s Textbook emphasizes the critical importance of excluding thrombosis prior to MLD treatment and recommends that patients with active DVT or a history of thromboembolic events within 6 months not undergo MLD (with some exception). DVTs in the acute phase are at risk of dislodging & creating a PE which can kill a person. In the subacute phase (which occurs over the next several weeks), there is typically pain, redness and swelling. The body begins to break down the clot in a process known as fibrinolysis, where enzymes dissolve fibrin and other clot components. As this process happens, part of the clot is reabsorbed, while the remaining structure becomes more organized and fibrous. In the chronic phase (month 3-6), the clot typically becomes firm and organized (restructured with scar tissue) and has little risk of dislodging by month 6.

The exception to waiting 6 months is if a person has a filter and/or receives anticoagulation medication. After stabilization with anticoagulant therapy, MLD may be safely resumed after a 2 to 4-week period (if the physician approves MLD).

Contraindications to Manual Lymph Drainage: Insights from Foldi’s Textbook of Lymphology (part 1 of 3)

Manual Lymph Drainage (MLD) is a therapeutic technique designed to stimulate the lymphatic system, promoting the movement of lymph and improving the drainage of excess fluid. This technique is widely used for conditions such as lymphedema, post-surgical recovery, and certain inflammatory disorders. However, MLD is not appropriate for all patients. According to Foldi’s Textbook of Lymphology, it is essential to understand specific contraindications to ensure patient safety and prevent complications. Here, we will explore some of these contraindications, providing a deeper understanding of when MLD should be avoided.

1. Acute Infections

One of the primary contraindications to MLD is the presence of acute infections. This includes bacterial, viral, or fungal infections, which could be exacerbated by the increased circulation induced by MLD. The stimulation of lymphatic flow could spread infectious agents through the body, worsening the condition or increasing the risk of sepsis. Conditions such as cellulitis, abscesses, or acute skin infections require medical treatment and should not be treated with MLD until the infection is resolved. Interestingly, the body protects itself against infectious agents by causing lymphangions to spasm. This contraction is part of the body’s attempt to limit the spread of infection or inflammation by slowing down lymph flow and creating a “barrier” effect. When performing MLD properly (which includes gentle, rhythmic strokes), the parasympathetic nervous system (the “rest and digest system”) is reflexively stimulated, causing relaxation and enhancing lymphatic circulation. As a result, these lymphangion spasms can relax, potentially allowing the spread of the infection to other parts of the body.

2. Malignant Diseases (Cancer)

While MLD can be beneficial for some cancer-related issues, it is contraindicated in active cancer or in cases where the patient has metastatic disease. Foldi emphasizes that manual drainage may inadvertently promote the spread of cancer cells, particularly in individuals with untreated or advanced malignancy. The stimulation of lymph flow could potentially facilitate the movement of cancerous cells, thus accelerating metastasis. MLD should not be performed over the affected areas in such cases unless specifically approved by an oncologist.

cancer cells

There is some debate about this in recent times by newer graduating lymphedema therapists. The debate centers around the fact that cancer cells choose whether or not to turn on or off. So, MLD isn’t “causing cancer.” But the caution is that cancer cells spread through one of two ways: blood flow or lymph flow. The concern with MLD during active cancer (particularly over the site of cancer) is that you speed up potential spread of cancer cells by stimulating lymph flow. I always disclose these facts to patients. I require patients with active cancer to sign a waiver if they wish to receive MLD. (Gloves should be worn if chemo is being administered.) In terminal cancer cases, the massage can be especially calming & comforting.

Contraindications to MLD

One of the more popular posts I’ve written is about contraindications to treatment (time when treatment should not be done). Lymphedema treatment includes manual lymph drainage (MLD), multi-layer short-stretch bandaging, skin care and exercise. Both MLD & bandaging have specific precautions.¹

General Precautions

The general precautions for MLD include:
– Active infection (caused by pathogens)
– Untreated cardiac failure
– Renal failure

There’s a relative contraindication for MLD:
– Malignant lymphedema (active cancer is causing the swelling)

Specific Precautions

But there are also specific precautions for MLD depending on where it is performed on the body. A sequence for MLD typically starts at the neck where the fluid drains. It doesn’t matter if swelling is in the legs, arms, head or elsewhere. But not all people will be appropriate for a neck sequence due to specific contraindications. For example, if someone has a cardiac arrhythmia related to an atrioventricular block or “AV-block” (referring to a block of the AV node in the heart’s electrical system). Doing a neck sequence could potentially stimulate the vagus nerve and cause cardiac arrest.

Understanding General Precautions (Active Infection)

So why are the general precautions a concern? In the case of an active infection caused by a pathogen (like bacteria in a cellulitis infection), performing MLD may cause the infection to spread. Fascinatingly, even though arterial & lymphatic flow increases during inflammation, in local inflammation, lymph vessels near the site of infection constrict. Thisprevents bacteria from escaping and entering the rest of the circulation. In performing MLD, this spasm could be relaxed, allowing normal flow to resume. The bacteria might then be allowed to move into the rest of the body & the infection could become systemic (i.e. sepsis).

(Untreated Heart Failure)

In the case of untreated heart failure, the concern is increasing pressure. The pressure in the veins returning blood to the heart near each collar bone (clavicle) is usually low. This is where lymphatic fluid returns to the body’s blood circulation. In untreated heart failure, the pressure is increased in these veins. Stimulating lymph flow with MLD would only add more fluid to a congested area and further increase the pressure. This can contribute to heart damage.

(Kidney Failure)

In the case of kidney failure, there is swelling in the body (often the lower part of the body). MLD would increase the amount of fluid returning to the heart and subsequently to the kidneys, increasing the fluid they must filter. This could overtax them. But the main reason MLD is not performed is because it would be of no use (if swelling being treated is due to kidney failure). That’s because kidney-caused swelling is edema, not lymphedema. The lymph vessels are already working as hard as they can to help get rid of the excess fluid. MLD speeds up lymphatic flow but beyond its normal high-working speed.

(Active Cancer)

In the case of cancer, MLD is a relative precaution. Meaning, there’s some room for discernment. The primary reason for avoiding MLD in the case of cancer is the potential to spread the cancer cells. (Cancer spreads through one of two ways: blood or lymph flow.) However, according to Foldi, molecular biology showed metastasis formation is an active process controlled by the cancer cells themselves. For example, cancer cells secrete a protein called vascular endothelial growth factor C (VEGF-C). ² This is responsible for creating new lymphatic vessels within and around a tumor from existing ones (lymphangiogenesis). Nonetheless, many therapists prefer to avoid the area of the tumor to avoid any potential accusation of / or potential of hastening cancer cell transportation.

It’s also important to know if a patient is receiving adequate cancer treatment and that the cancer is responding. One note: Some suggest avoiding MLD for 2-3 days after chemo to allow the drug(s) to remain in the body and do their job. Others suggest proceeding with MLD to help distribute the chemo throughout the body and to use gloves to prevent transmission of chemo through the skin to the therapist. I would tend to side with the former group (avoid MLD – at least in the area of the body directly affected by the tumor¹). But it’s important to check with the oncologist before providing any treatment.
