TL;DR: It is shown that whilst good evidence for the use of compression is available in some clinical indications, there is much still to be discovered.
Abstract: Aim The aim of this study was to review published literature concerning the use of compression treatments in the management of venous and lymphatic diseases and establish where reliable evidence exists to justify the use of medical compression and where further research is required to address areas of uncertainty. Methods The authors searched medical literature databases and reviewed their own collections of papers, monographs and books for papers providing information about the effects of compression and randomized clinical trials of compression devices. Papers were classified in accordance with the recommendations of the GRADE group to categorize their scientific reliability. Further classification was made according to the particular clinical problem that was addressed in the papers. The review included papers on compression stockings, bandages and intermittent pneumatic compression devices. Results The International Compression Club met once in Vienna and corresponded by email in order to reach an agreement of how the data should be interpreted. A wide range of compression levels was reported to be effective. Low levels of compression 10-30 mmHg applied by stockings are effective in the management of telangiectases after sclerotherapy, varicose veins in pregnancy, the prevention of edema and deep vein thrombosis (DVT). High levels of compression produced by bandaging and strong compression stockings (30-40 mmHg) are effective at healing leg ulcers and preventing progression of post-thrombotic syndrome as well as in the management of lymphedema. In some areas no reliable evidence was available to permit recommendations of level of compression or duration of treatment. These included: management of varicose veins to prevent progression, following surgical treatment or sclerotherapy for varicose veins, and the level of compression required to treat acute DVT. Conclusion This review shows that whilst good evidence for the use of compression is available in some clinical indications, there is much still to be discovered. Little is know about dosimetry in compression, for how long and at what level compression should be applied. The differing effects of elastic and short-stretch compression are also little understood.

TL;DR: A systematic approach has been developed with recommendations based upon cumulative evidence from the literature, which range from Level I and Grade A to Level III and Grade C, and includes meta-analysis Meta-analyses but there should be caution as to their possible abuse.
Abstract: Disclaimer Due to the evolving field of medicine, new research may, in due course, modify the recommendations presented in this document. At the time of publication, every attempt has been made to ensure that the information provided is up to date and accurate. It is the responsibility of the treating physician to determine the best treatment for the patient. The authors, committee members, editors, and publishers cannot be held responsible for any legal issues that may arise from the citation of this statement. Rules of evidence Management of patients with chronic venous disorders has been traditionally undertaken subjectively among physicians, often resulting in less than optimal strategies. In this document, a systematic approach has been developed with recommendations based upon cumulative evidence from the literature. Levels of evidence and grades of recommendation range from Level I and Grade A to Level III and Grade C. Level I evidence and Grade A recommendations derive from scientifically sound randomized clinical trials in which the results are clear-cut. Level II evidence and Grade B recommendations derive from clinical studies in which the results among trials often point to inconsistencies. Level III evidence and Grade C recommendations result from poorly designed trials or from small case series.1, 2 Meta-analysis Meta-analyses are included in the present document but there should be caution as to their possible abuse. Certain studies may be included in a meta-analysis carelessly without sufficiently understanding of substantive issues, ignoring relevant variables, using heterogenous findings or interpreting results with a bias.3 It has been demonstrated that the outcomes of 12 large randomized controlled trials were not predicted accurately 35% of the time by the meta-analyses published previously on the same topics.4

TL;DR: The splash pattern is the earliest finding on indocyanine green lymphography of asymptomatic limbs of secondary lower extremity lymphedema patients, indicating that the leg dermal backflow stage allows early diagnosis of secondaryLower Extremity lyMPhedema even in a subclinical stage.
Abstract: BACKGROUND Early diagnosis and treatment are as important for management of secondary lymphedema following cancer treatment as in primary cancer treatment. Indocyanine green lymphography is the modality of choice for routine follow-up evaluation of patients at high risk of developing lymphedema after cancer therapy. METHODS Fifty-six limbs of 28 so-called unilateral secondary lower extremity lymphedema patients who underwent indocyanine green lymphography were compared with dermal backflow patterns of indocyanine green lymphography on 28 asymptomatic limbs and assessed using leg dermal backflow stage. RESULTS Of 28 asymptomatic limbs of secondary lower extremity lymphedema patients, the dermal backflow patterns were detected in 19 limbs but were absent in nine limbs. Significant differences were seen between asymptomatic limbs with dermal backflow patterns (n=19) and limbs without them (n=9): age, 51.4±15.3 years versus 34.8±12.7 years (p=0.007); body weight, 75.1±7.9 kg versus 50.1±5.3 kg (p=0.012); body mass index, 23.1±4.2 versus 19.7±1.8 (p=0.005); leg dermal backflow stage of asymptomatic limb, 1.2±0.4 versus 0.0±0.0 (p<0.001); and leg dermal backflow stage of symptomatic limb, 3.5±0.6 versus 2.8±0.8 (p=0.033). CONCLUSIONS The splash pattern is the earliest finding on indocyanine green lymphography of asymptomatic limbs of secondary lower extremity lymphedema patients. The leg dermal backflow stage allows early diagnosis of secondary lower extremity lymphedema even in a subclinical stage. The concept of subclinical lymphedema could play an important role in early diagnosis and prevention of lymphedema after cancer treatment. CLINICAL QUESTION/LEVEL OF EVIDENCE Diagnostic, V.

TL;DR: To critically analyze the contemporary published research that pertains to the individual components of complete decongestive therapy (CDT), as well as CDT as a bundled intervention in the treatment of lymphedema.
Abstract: Objective To critically analyze the contemporary published research that pertains to the individual components of complete decongestive therapy (CDT), as well as CDT as a bundled intervention in the treatment of lymphedema. Data Sources Publications were retrieved from 11 major medical indices for articles published from 2004-2010 by using search terms for lymphedema and management approaches. Literature archives of the authors and reference lists were examined through 2011. Study Selection A research librarian assisted with initial literature searches by using search terms used in the Best Practice for the Management of Lymphoedema , plus expanded terms, for literature related to lymphedema. Authors sorted relevant literature for inclusion and exclusion; included articles were sorted into topical areas for data extraction and assessment of level of evidence by using a published grading system and consensus process. The authors reviewed 99 articles, of which 26 met inclusion criteria for individual studies and 1 case study did not meet strict inclusion criteria. In addition, 14 review articles and 2 consensus articles were reviewed. Data Extraction Information on study design and/or objectives, participants, outcomes, intervention, results, and study strengths and weaknesses was extracted from each article. Study evidence was categorized according to the Oncology Nursing Society Putting Evidence into Practice level of evidence guidelines after achieving consensus among authors. Data Synthesis Levels of evidence were only moderately strong, because there were few randomized controlled trials with control groups, well-controlled interventions, and precise measurements of volume, mobility and/or function, and quality of life. Treatment interventions were often bundled, which makes it difficult to determine the contribution of each individual component of treatment to the outcomes achieved. Conclusions CDT is seen to be effective in reducing lymphedema. This review focuses on original research about CDT as a bundled intervention and 2 individual components, manual lymph drainage and compression bandages. Additional studies are needed to determine the value and efficacy of the other individual components of CDT.
