Lymphedema Center - Emily Iker, MD

Swelling can change the tissues beneath the skin long before those changes are fully visible from the outside. While physical examination and medical history remain central to diagnosing lymphatic and venous conditions, ultrasound can provide additional information. This noninvasive imaging technology helps physicians examine tissue composition, fluid accumulation, fibrosis, and certain circulation problems that may contribute to persistent swelling. Dr. Emily Iker has helped advance the clinical use of diagnostic ultrasonography in lymphatic medicine through pioneering published research. At the Lymphedema Center in Santa Monica, she combines ultrasound findings with a detailed evaluation of each patient’s symptoms, tissue changes, medical history, and swelling pattern. This integrated approach helps distinguish among conditions that may appear similar while supporting more individualized recommendations. What Is Diagnostic Ultrasound? Diagnostic ultrasound, also called ultrasonography, uses high-frequency sound waves to create images of structures beneath the skin. A small handheld device called a transducer is moved across the area being examined. The sound waves reflect differently as they encounter fluid, fatty tissue, connective tissue, blood vessels, and other structures. Ultrasound does not use radiation and does not require an incision. Most examinations are comfortable, although patients with very tender tissue may notice mild pressure as the transducer moves over the affected area. Different types of ultrasound answer different clinical questions. Tissue ultrasonography may be used to examine changes associated with lymphatic or adipose tissue disorders. Vascular ultrasound focuses on blood flow through the veins or arteries. Depending on the symptoms, a patient may need one type of assessment or coordinated testing involving both. How Does Ultrasound Support Lymphatic Assessment? When lymphatic drainage is impaired, protein-rich fluid can accumulate within the tissues. Over time, ongoing inflammation may contribute to thickening and fibrosis. These changes can alter the appearance of the skin and subcutaneous tissues on ultrasound. Diagnostic ultrasonography may help Dr. Iker assess: Skin and subcutaneous tissue thickness Patterns of fluid accumulation Fibrosis or tissue hardening Differences between affected and unaffected areas Changes that may not be reflected by circumference measurements alone Tissue characteristics associated with lymphedema or lipedema Progression or improvement documented during follow-up care Research continues to evaluate how ultrasound measurements can support earlier and more objective assessment of lymphedema. Recent clinical evidence indicates that ultrasound-based skin measurements may reveal changes that limb circumference alone does not capture, although ultrasound is not a universal stand-alone diagnostic test. Can Ultrasound Help Distinguish Different Swelling Conditions? Several conditions can enlarge an arm or leg, yet they do not produce identical changes beneath the skin. Ultrasonography may provide useful supporting information when distinguishing among: Lymphedema Lipedema Lipo-lymphedema Phlebo-lymphedema Generalized fluid retention Localized fatty tissue or lipomas Inflammatory tissue changes For example, lymphedema may lead to fluid accumulation and progressive fibrosis, while lipedema primarily affects the subcutaneous fat and connective tissue in a characteristic distribution. Some patients have overlapping conditions, so imaging findings must be interpreted alongside symptoms and physical signs. Ultrasound cannot independently determine the cause of every type of swelling. Bloodwork, lymphoscintigraphy, MRI, CT imaging, genetic evaluation, or consultation with another medical specialist may be recommended when additional information is needed. What Is the Role of Venous Ultrasound? Venous disease can cause or worsen swelling, particularly in the lower legs. A venous duplex ultrasound combines traditional imaging with Doppler technology to evaluate the direction and speed of blood flow. It can help identify blood clots, venous obstruction, or valves that allow blood to flow backward. This testing differs from the tissue ultrasonography used to assess changes associated with lymphatic dysfunction. When symptoms suggest chronic venous insufficiency, a previous deep vein thrombosis, or another vascular problem, Dr. Iker may recommend venous testing through an appropriate vascular provider. Identifying venous involvement is especially important in suspected phlebo-lymphedema. Longstanding venous pressure can place increasing demands on the lymphatic system until both systems contribute to persistent swelling. In these cases, care may need to address the lymphatic component while a vascular specialist evaluates or treats the venous condition.

Swelling disorders can differ substantially in their causes, symptoms, tissue changes, and effects on daily life. Even patients with the same diagnosis may have different needs depending on the areas affected, symptom severity, circulation, mobility, age, medical history, and ability to follow a home-care routine. For these reasons, effective lymphatic care cannot be based on a single standardized treatment plan. At the Lymphedema Center in Santa Monica, Dr. Emily Iker creates individualized treatment plans for patients with lymphatic, venous, adipose, and related swelling conditions. Her approach combines a detailed medical evaluation with diagnostic ultrasonography when appropriate. Recommendations are then shaped around the patient’s diagnosis, physical findings, health considerations, functional goals, and everyday circumstances. How Is an Individualized Treatment Plan Created? Treatment planning begins with determining what is causing or contributing to the patient’s symptoms. Dr. Iker reviews when swelling or tissue changes began, how they have progressed, and whether they are affected by activity, elevation, heat, travel, hormonal changes, or prolonged sitting or standing. The evaluation may also consider: Previous surgeries, injuries, infections, or cancer treatment Venous disease or a history of blood clots Pain, bruising, heaviness, or tissue tenderness Skin condition and episodes of cellulitis Current medications and medical conditions Strength, balance, mobility, and joint movement Previous treatments and how the patient responded Work responsibilities, caregiving demands, and lifestyle The patient’s priorities and treatment goals Diagnostic ultrasonography may be used to assess tissue thickness, fluid accumulation, fibrosis, or other changes associated with lymphatic and adipose disorders. Vascular studies, bloodwork, imaging, or evaluation by another specialist may be recommended when additional information is needed. How Do Treatment Plans Differ by Condition? The diagnosis influences which therapies may be useful, which precautions are necessary, and whether other specialists should be involved. Lymphedema and Limb Swelling For primary or secondary lymphedema, care may focus on controlling fluid accumulation, protecting the skin, reducing the risk of infection, and preserving mobility. Unexplained limb swelling requires careful assessment before initiating lymphatic treatment, as blood clots, infections, medication side effects, and systemic medical conditions can cause similar symptoms. Phlebo-Lymphedema and Venous Insufficiency When venous pressure and lymphatic dysfunction both contribute to swelling, the plan may address the lymphatic component while coordinating vascular evaluation or treatment. Compression must be selected with attention to arterial circulation, skin integrity, wounds, and the severity of venous disease. Lipedema Lipedema treatment planning may emphasize tissue comfort, mobility, joint protection, symptom management, and associated swelling. Recommendations may also account for bruising, pain, hormonal history, nutritional needs, and the possible development of secondary lymphedema. Patients considering lipedema reduction surgery may need coordinated preoperative or postoperative care. Pediatric and Geriatric Swelling Conditions Plans for children consider growth, developmental stage, school activities, family involvement, and the long-term practicality of treatment. For older adults, recommendations may need to account for fragile skin, reduced strength, circulatory concerns, balance problems, chronic conditions, or caregiver assistance. Dercum’s and Madelung’s Diseases Dercum’s disease may require a multidisciplinary plan centered on painful fatty tissue, mobility, associated swelling, and daily function. Madelung’s disease may require monitoring and referral when fatty deposits affect movement, breathing, swallowing, sleep, or nearby structures. Lymphatic therapies are recommended only when the evaluation identifies a relevant swelling component. Which Treatments May Be Included? Depending on the diagnosis and medical findings, an individualized plan may include: Manual lymphatic drainage Compression garments or specialized bandaging Pneumatic compression with Dr. Iker’s FDA-approved compression sleeve insert for selected patients Movement or exercise adapted to physical ability Strategies for reducing cellulitis and wound risks Nutritional or weight-management guidance when relevant Education for family members or caregivers Coordination with vascular, surgical, cardiac, renal, pain-management, or other specialists Not every therapy is appropriate for every patient. Compression, for example, may require modification or medical clearance in patients with arterial disease, certain cardiac conditions, reduced sensation, wounds, or fragile skin.

Pneumatic compression uses controlled, sequential pressure to help support the movement of fluid through the affected area. During treatment, an inflatable compression garment is connected to a pneumatic device. Chambers within the garment inflate and release in sequence, applying pressure along the limb to support lymphatic and venous return. At the Lymphedema Center in Santa Monica, Dr. Emily Iker offers pneumatic compression device treatment in the office as part of individualized care for lymphatic and swelling disorders. Treatment includes the practice’s FDA-approved compression sleeve insert and is recommended based on the patient’s diagnosis, swelling pattern, tissue condition, circulation, and overall treatment needs. image007 How Does Pneumatic Compression Work? A pneumatic compression device uses a pump to deliver controlled pressure through an inflatable garment. Rather than applying constant pressure, chambers within the garment inflate and release in a sequence designed to encourage fluid movement through the affected area. Pneumatic compression may be incorporated into a broader treatment plan to help manage persistent swelling, heaviness, tightness, or fluid accumulation. Depending on the patient, it may be used alongside compression garments, manual lymphatic drainage, movement, skin care, and other lymphatic management strategies. Who May Benefit From Pneumatic Compression? Pneumatic compression may be considered for selected patients with lymphedema and other conditions involving lymphatic swelling or fluid accumulation. Dr. Iker evaluates each patient before recommending treatment because not every form of swelling has the same cause or responds to compression in the same way. The evaluation may consider: The cause and location of swelling Tissue firmness and fibrosis Skin condition Arterial and venous circulation Pain, sensation, and mobility Previous treatments and response to compression Other medical conditions that may affect treatment This individualized approach helps determine whether pneumatic compression is appropriate and how it should fit into the patient’s overall care plan. What Is the FDA-Approved Compression Sleeve Insert? Dr. Iker has developed an FDA-approved compression sleeve design that may be incorporated into pneumatic compression device treatment at the Lymphedema Center. The sleeve reflects the practice’s focus on individualized compression and Dr. Iker’s decades of experience treating patients with lymphatic disorders. During your consultation, Dr. Iker can explain how the sleeve insert is used as part of treatment and whether it is appropriate for your specific condition. How Does Pneumatic Compression Fit Into Lymphatic Care? Pneumatic compression is typically one component of a broader management strategy rather than a stand-alone solution. Depending on the patient’s needs, an individualized treatment plan may also include manual lymphatic drainage, compression garments or bandaging, movement and exercise, skin care, and strategies for managing symptoms at home. Dr. Iker considers the patient’s diagnosis, physical findings, functional needs, and response to treatment when determining which therapies should be combined. Treatment recommendations may also change over time as swelling, tissue condition, mobility, or other health needs evolve.

Manual lymphatic drainage (MLD) is a specialized hands-on technique designed to encourage lymphatic fluid to move away from areas where it has accumulated. Unlike traditional massage, MLD uses light, rhythmic movements that follow the pathways of the lymphatic system. It may help reduce swelling, soften congested tissue, ease sensations of heaviness or tightness, and support movement when incorporated into an appropriate treatment plan. At the Lymphedema Center in Santa Monica, MLD is recommended according to each patient’s diagnosis, circulation, tissue condition, and overall health. Dr. Emily Iker’s board certification in Physical Medicine and Rehabilitation informs an approach centered on both symptom management and physical function. Before treatment begins, she evaluates the cause of the swelling and whether lymphatic drainage is medically appropriate. What Is Manual Lymphatic Drainage? The lymphatic system collects excess fluid, proteins, and cellular waste from the tissues and returns them to circulation. When lymphatic vessels or nodes are absent, damaged, or overwhelmed, fluid may remain in the tissues, contributing to swelling. MLD uses carefully directed skin-stretching movements to stimulate superficial lymphatic vessels. Treatment generally begins in areas with functioning drainage before progressing toward the swollen region. This sequence is intended to create pathways through which fluid may be redirected. Because most lymphatic vessels are located close to the skin, the pressure is much lighter than that used during deep-tissue massage. Forceful kneading is not necessary and may be uncomfortable or inappropriate for tissues affected by lymphedema, lipedema, inflammation, or fibrosis. Which Conditions May Benefit From MLD? Manual lymphatic drainage is most closely associated with lymphedema, but it may be considered for several conditions treated at the Center, including: Primary or secondary lymphedema Phlebo-lymphedema Lipo-lymphedema Lipedema Chronic Limb swelling following surgery, injury, or cancer treatment Pediatric or geriatric lymphatic swelling Selected cases involving Dercum’s disease MLD does not address every cause of enlargement. For example, it cannot remove the abnormal fatty deposits associated with lipedema, Dercum’s disease, or Madelung’s disease. It may still be useful when lymphatic fluid accumulation exists alongside one of these conditions. Venous insufficiency may also contribute to leg swelling, but significant venous or arterial disease can affect treatment decisions. When vascular involvement is suspected, Dr. Iker may recommend additional testing or coordinated care before incorporating MLD. What Happens During an MLD Session? Treatment is adapted to the location and severity of swelling. The patient is positioned comfortably while gentle movements are applied directly to the skin. Depending on the areas involved, the session may address the neck, trunk, arms, legs, abdomen, face, or other regions. Patients commonly describe MLD as calming and comfortable. The technique should not cause significant pain, bruising, or forceful compression. Tender tissues may require additional modifications, especially in patients with lipedema or Dercum’s disease. Patients may also be instructed on how to perform self-MLD techniques that can be incorporated into their at-home conservative management routine. MLD may produce temporary changes in swelling or tissue comfort, but it is rarely used as the only form of lymphedema management. Results depend on the cause and stage of the condition, the presence of fibrosis, and the patient’s ability to maintain improvements between sessions. Leg massage photo Emily Iker Self-MLD How Does MLD Fit Into a Broader Treatment Plan? Manual lymphatic drainage is often part of complete decongestive therapy, a broader approach to managing lymphedema. Depending on the patient, treatment may also include: Compression bandaging or garments Movement and therapeutic exercises Skin and nail care Pneumatic compression Education about infection prevention Weight-management or nutritional guidance when relevant A personalized home-care routine Compression may help prevent fluid from returning after it has been redirected. Movement supports circulation and lymphatic flow, while skin care helps reduce the risk of cellulitis. Each component is selected according to the patient’s health, functional ability, and treatment goals. Some patients may also be taught simplified self-MLD techniques. These movements should be demonstrated by a qualified professional, as the direction and sequence depend on the affected area and the available lymphatic pathways.
