    Diagnostic Accuracy of Lymphoscintigraphy for Lymphedema and Analysis of False-Negative Tests
    (Wolters Kluwer Health, 2017) Hassanein, Aladdin H.; Maclellan, Reid; Grant, Frederick; Greene, Arin
    Background: Lymphedema is the chronic enlargement of tissue due to inadequate lymphatic function. Diagnosis is made by history and physical examination and confirmed with lymphoscintigraphy. The purpose of this study was to assess the accuracy of lymphoscintigraphy for the diagnosis of lymphedema and to determine characteristics of patients with false-negative tests. Methods: Individuals referred to our lymphedema program with “lymphedema” between 2009 and 2016 were analyzed. Subjects were assessed by history, physical examination, and lymphoscintigraphy. Patient age at presentation, duration of lymphedema, location of disease, gender, previous infections, and lymphedema type were analyzed. Results: The study included 227 patients (454 limbs); lymphedema was diagnosed clinically in 169 subjects and confirmed by lymphoscintigraphy in 162 (117 primary, 45 secondary; 96% sensitivity). Fifty-eight patients were thought to have a condition other than lymphedema, and all had negative lymphoscintigrams (100% specificity). A subgroup analysis of the 7 individuals with lymphedema clinically, but normal lymphoscintigrams, showed that all had primary lymphedema; duration of disease and infection history were not different between true-positive and false-negative lymphoscintigram results (P = 0.5). Two patients with a false-negative test underwent repeat lymphoscintigraphy, which then showed lymphatic dysfunction consistent with lymphedema. Conclusion: Lymphoscintigraphy is very sensitive and specific for lymphedema. All patients with false-negative studies had primary lymphedema. A patient with a high clinical suspicion of lymphedema and a normal lymphoscintigram should be treated conservatively for the disease and undergo repeat lymphoscintigraphy.

    Obesity-induced Lymphedema Nonreversible following Massive Weight Loss
    (Wolters Kluwer Health, 2015) Greene, Arin; Grant, Frederick; Maclellan, Reid
    Summary: Lymphedema is the progressive enlargement of tissue due to inadequate lymphatic function. Obesity-induced lymphedema of the lower extremities can occur once a patient’s body mass index (BMI) exceeds 50. We report our first patient with obesity-induced lower extremity lymphedema who was followed prospectively before and after weight loss. A 46-year-old woman with a BMI of 80 presented to our Lymphedema Program complaining of bilateral lower extremity swelling. Lymphoscintigraphy showed impaired lymphatic drainage of both lower extremities consistent with lymphedema. She was referred to a bariatric surgical weight-loss center and underwent a sleeve gastrectomy. After reaching her new steady-state BMI of 36 eighteen months following her procedure, lymphoscintigraphy showed no improvement in lower extremity lymphatic function. Patients at risk for obesity-induced lymphedema should be counseled that they should seek weight-loss interventions before their BMI reaches 50, a threshold at which point lower extremity lymphedema may occur. Unlike other comorbidities that reverse following massive weight loss, obesity-induced lymphedema may not resolve.

    Obesity-induced Upper Extremity Lymphedema
    (Wolters Kluwer Health, 2013) Greene, Arin; Maclellan, Reid
    Summary: Obesity increases the risk of upper extremity lymphedema following treatment for breast cancer and can cause lower extremity lymphatic dysfunction in extremely obese individuals. We report the first patient with obesity-induced upper extremity lymphedema. A 62-year-old man with a previous body mass index (BMI) of 105.6, presented with a BMI 60.3 following weight loss. He complained of lymphedema of all 4 extremities, which was confirmed by lymphoscintigraphy. Because the upper limbs are more resistant to lymphedema than the lower extremities, a higher BMI threshold may be necessary to cause upper extremity lymphatic dysfunction.

    Resolution of Primary Lymphedema: A Case Report
    (Wolters Kluwer Health, 2017) Goss, Jeremy A.; Maclellan, Reid; Beijnen, Usha E. A.; Greene, Arin
    Summary: Primary lymphedema is a rare, progressive disease that typically affects the lower extremity. The condition is not curable, and the limb enlarges over time because of subcutaneous fibroadipose deposition. We present a patient with clinical and radiographical evidence of resolution of primary lymphedema. This observation may provide greater insight into the pathophysiology of the disease.

    Combined Lymphedema and Capillary Malformation of the Lower Extremity
    (Wolters Kluwer Health, 2016) Maclellan, Reid; Chaudry, Gulraiz; Greene, Arin
    Background: Primary lymphedema and capillary malformation are independent vascular malformations that can cause overgrowth of the lower extremity. We report a series of patients who had both types of malformations affecting the same leg. The condition is unique but may be confused with other types of vascular malformation overgrowth conditions (eg, Klippel–Trenaunay and Parkes Weber). Methods: Our Vascular Anomalies Center and Lymphedema Program databases were searched for patients with both capillary malformation and lymphedema. Diagnosis of lymphedema–capillary malformation was made by history, physical examination, and imaging studies. Because lymphedema–capillary malformation has phenotypical overlap with other conditions, only patients who had imaging confirming their diagnosis were included in the analysis. Clinical and radiological features, morbidity, and treatment were recorded. Results: Eight patients (4 females and 4 males) had confirmed lymphedema–capillary malformation. Referring diagnosis was Klippel–Trenaunay syndrome (n = 4), diffuse capillary malformation with overgrowth (n = 3), or lymphatic malformation (n = 1). The condition was unilateral (n = 6) or bilateral (n = 2). Morbidity included infection (n = 6), difficulty fitting clothes (n = 6), bleeding or leaking vesicles (n = 5), leg length discrepancy (n = 4), and difficulty ambulating (n = 3). All patients were managed with compression regimens. Operative management was liposuction (n = 3), treatment of phlebectatic veins (n = 3), staged skin/subcutaneous excision (n = 1), and/or epiphysiodesis (n = 1). Conclusions: Lymphedema and capillary malformation can occur together in the same extremity. Both conditions independently cause limb overgrowth primarily because of subcutaneous adipose deposition. Compression garments and suction-assisted lipectomy can improve the condition. Lymphedema–capillary malformation should not be confused with other vascular malformation overgrowth diseases that have different morbidities and treatments.
