This version of the article contains supplemental content.This clinical content conforms to AAFP criteria for continuing medical education (CME). Edema is an accumulation of fluid in the intercellular tissue that results from an abnormal expansion in interstitial fluid volume.
The rapid development of generalized pitting edema associated with systemic disease requires timely diagnosis and management. Acute swelling of a limb over a period of less than 72 hours is more characteristic of deep venous thrombosis (DVT), cellulitis, ruptured popliteal cyst, acute compartment syndrome from trauma, or recent initiation of calcium channel blockers (Figures 1 and 2).
Mechanical therapies, including leg elevation and compression stockings with 20 to 30 mm Hg for mild edema and 30 to 40 mm Hg for severe edema complicated by ulceration, are recommended.1,4,5,8,29 Compression therapy is contraindicated in patients with peripheral arterial disease. STUDDIFORD, MD, Thomas Jefferson University Hospital, Philadelphia, PennsylvaniaSARAH PICKLE, MD, Rutgers Robert Wood Johnson Medical School, New Brunswick, New JerseyAMBER S. The chronic accumulation of edema in one or both lower extremities often indicates venous insufficiency, especially in the presence of dependent edema and hemosiderin deposition. A study of 120 patients with venous ulcers showed that 6% had mixed arterial-venous ulcers.30 In another study, a higher prevalence of peripheral arterial disease was found in women with symptoms of chronic venous insufficiency vs. For mild to moderate chronic venous insufficiency, oral horse chestnut seed extract may be an alternative or adjunctive treatment to compression therapy.33,34Local skin and wound care of venous ulcers is essential in preventing secondary cellulitis and dermatitis.
Patients who have had deep venous thrombosis should wear compression stockings to prevent postthrombotic syndrome. The mechanism often includes the retention of salt and water with increased capillary hydrostatic pressure. If clinical suspicion for deep venous thrombosis remains high after negative results are noted on duplex ultrasonography, further investigation may include magnetic resonance venography to rule out pelvic or thigh proximal venous thrombosis or compression. The initial goal is to improve fluid resorption until a maximum therapeutic response is reached. Obstructive sleep apnea may cause bilateral leg edema even in the absence of pulmonary hypertension.



Graves disease can lead to pretibial myxedema, whereas hypothyroidism can cause generalized myxedema.
The maintenance phase of treatment includes compression stockings at 30 to 40 mm Hg.11,37,38 Pneumatic compression devices have been shown to augment standard therapies. Brawny, nonpitting skin with edema characterizes lymphedema, which can present in one or both lower extremities. Although considered a diagnosis of exclusion, obstructive sleep apnea has been shown to cause edema. Possible secondary causes of lymphedema include tumor, trauma, previous pelvic surgery, inguinal lymphadenectomy, and previous radiation therapy. Use of pneumatic compression devices or compression stockings may be helpful in these cases. Edema should also be evaluated for pitting, tenderness, and skin changes.Pitting describes an indentation that remains in the edematous area after pressure is applied (Figure 3).
Lower extremity examination should focus on the medial malleolus, the bony portion of the tibia, and the dorsum of the foot.
Key search terms were edema, oedema, peripheral edema, lower extremity edema, venous insufficiency, deep vein thrombosis, lymphedema, obstructive sleep apnea, and iliac vein syndrome. Also reviewed were the Cochrane database, National Guideline Clearinghouse, Essential Evidence Plus, UpToDate, and the U.S.
For example, acute DVT and cellulitis (Figure 4) may produce increased warmth over the affected area. Because of the deposition of hemosiderin, chronic venous insufficiency is often associated with skin that has a brawny, reddish hue and commonly involves the medial malleolus4,5,8 (eFigure A). As venous insufficiency progresses, it can result in lipodermatosclerosis (Figure 5), which is associated with marked sclerotic and hyperpigmented tissue, and characterized by fibrosis and hemosiderin deposition that can lead to venous ulcers over the medial malleolus. Myxedema from hypothyroidism presents with a generalized dry, thick skin with nonpitting periorbital edema and yellow to orange skin discoloration over the knees, elbows, palms, and soles.


In the late stages of complex regional pain syndrome, the skin may appear shiny with atrophic changes.

Long-standing lymphedema with thickened, verrucous skin.Examination of the feet is important in lower extremity edema. In patients with lymphedema, there is an inability to tent the skin of the dorsum of the second toe using a pincer grasp (Kaposi-Stemmer sign)7,9–11 (eFigure D).

The following laboratory tests are useful for diagnosing systemic causes of edema: brain natriuretic peptide measurement (for CHF), creatinine measurement and urinalysis (for renal disease), and hepatic enzyme and albumin measurement (for hepatic disease).
In patients who present with acute onset of unilateral upper or lower extremity swelling, a d-dimer enzyme-linked immunosorbent assay can rule out DVT in low-risk patients. However, this test has a low specificity, and d-dimer concentrations may be elevated in the absence of thrombosis.13,17,18ULTRASONOGRAPHYVenous ultrasonography is the imaging modality of choice in the evaluation of suspected DVT. Therefore, indirect radionuclide lymphoscintigraphy, which shows absent or delayed filling of lymphatic channels, is the method of choice for evaluating lymphedema when the diagnosis cannot be made clinically.11,21MAGNETIC RESONANCE IMAGINGPatients with unilateral lower extremity edema who do not demonstrate a proximal thrombosis on duplex ultrasonography may require additional imaging to diagnose the cause of edema if clinical suspicion for DVT remains high.
