[Classification and nomenclature of current materials for compression therapy]. / Einteilung und Nomenklatur der aktuellen Materialien zur Kompressionstherapie.

Compression therapy has been an essential part of conservative therapy for people with chronic wounds and edema of the lower extremities for hundreds of years. The initiated therapy can be divided into the decongestion phase, maintenance phase, and prevention. The choice of the respective compression materials is based, among other factors, on these phases, the clinical stage and symptoms, the needs of the affected person and their physical abilities. Today, a wide range of different materials and methods are available for compression therapy. Thus, it is increasingly difficult to keep an overview of these treatment options, especially since the nomenclature used by the manufacturers is often inconsistent. Thus, the materials and methods for compression therapy currently available in German-speaking countries and their clinical indications are described in this review article. In addition, a uniform nomenclature is proposed, on the basis of which an appropriate exchange between all those involved in the care of people with compression therapy is guaranteed.

[Compression therapy of venous leg ulcers in the decongestion phase]. / Kompressionstherapie des Ulcus cruris venosum in der Phase der Entstauung.

Compression therapy is the basis for successful treatment in most patients with venous leg ulcers. Concerning compression therapy, the initial phase of decongestion and the following phase of maintenance should be differentiated. While in the maintenance phase (ulcer) stocking systems are now frequently recommended, in the decongestion phase compression bandages are mostly still used, which however are often inappropriately applied. In German-speaking countries, compression therapy with short-stretch bandages has a long tradition. However, their correct application requires good training and monitoring, which is often lacking in daily practice. Less error-prone treatment alternatives are multicomponent systems, some of which have an optical marker for the control of the correct subbandage pressure. In another new type of compression system, which is called adaptive or wrap bandages, the compression pressure can be adjusted using a Velcro fastener. Accompanying intermittent pneumatic compression therapy can also be used in the decongestion phase. Thus, there are now several different treatment options that can be used for the decongestion phase in patients with venous leg ulcers. Often bandages with short-stretch materials are very prone to errors and should in most cases be replaced by other compression systems today. The patient's preference, need, and capability should be considered when selecting the appropriate system for the individual patient.

Compression therapy for venous leg ulcers: risk factors for adverse events and complications, contraindications - a review of present guidelines.

INTRODUCTION: The adequate use of compression in venous leg ulcer treatment is equally important to patients as well as clinicians. Currently, there is a lack of clarity on contraindications, risk factors, adverse events and complications, when applying compression therapy for venous leg ulcer patients. METHODS: The project aimed to optimize prevention, treatment and maintenance approaches by recognizing contraindications, risk factors, adverse events and complications, when applying compression therapy for venous leg ulcer patients. A literature review was conducted of current guidelines on venous leg ulcer prevention, management and maintenance. RESULTS: Searches took place from 29th February 2016 to 30th April 2016 and were prospectively limited to publications in the English and German languages and publication dates were between January 2009 and April 2016. Twenty Guidelines, clinical pathways and consensus papers on compression therapy for venous leg ulcer treatment and for venous disease, were included. Guidelines agreed on the following absolute contraindications: Arterial occlusive disease, heart failure and ankle brachial pressure index (ABPI) <0.5, but gave conflicting recommendations on relative contraindications, risks and adverse events. Moreover definitions were unclear and not consistent. CONCLUSIONS: Evidence-based guidance is needed to inform clinicians on risk factor, adverse effects, complications and contraindications. ABPI values need to be specified and details should be given on the type of compression that is safe to use. Ongoing research challenges the present recommendations, shifting some contraindications into a list of potential indications. Complications of compression can be prevented when adequate assessment is performed and clinicians are skilled in applying compression.

Healing of an arterial leg ulcer by compression bandaging: a case report.

This case report demonstrates that arterial ulcers may heal with compression therapy. The patient was a 72-year-old woman with elevated blood pressure and type II diabetes mellitus, who underwent angiography because of a painful, non-healing ulcer over the shin. The angiography showed multisegment arterial occlusive disease, not amenable to surgical revascularisation. After 4 months of wearing inelastic bandages, with increased pressure over the ulcer area and hypertension and diabetes under control, the patient was pain-free and the ulcer had healed. The ankle-brachial pressure index (ABPI) increased from 0.54 at the start of treatment to 0.70. In patients with arterial leg ulcers, properly applied compression therapy using increased pressure over the wound may lead to an improvement of the arterial flow and to complete healing.

The Static Stiffness Index: an important parameter to characterise compression therapy in vivo.

The compression pressure, which corresponds to the dosage of compression therapy, has been widely neglected up to now, not only concerning scientific literature, but also in clinical practice. It is evident that compression pressures in the upright position and during walking are clinically more relevant than just the resting pressure. The Static Stiffness Index (SSI), which is the difference between standing and resting pressure, is a valuable parameter characterising the efficacy of a specific compression product to narrow/occlude the venous lumen. This is a prerequisite for reducing venous reflux and exerting a massaging effect necessary to improve the venous pumping function during movement. This article provides an overview of the recent literature on the SSI, which supports the recommendations of the International Compression Club. In addition, it aims to provide an insight on the importance of the SSI in daily practice, as an educational tool as well as in defining the properties of applied compression therapy in clinical research.

Recalcitrant Venous Leg Ulcers May Heal by Outpatient Treatment of Venous Disease Even in the Presence of Concomitant Arterial Occlusive Disease.

OBJECTIVE/BACKGROUND: Peripheral arterial occlusive disease (PAOD) is reported in about 15-20% of patients with venous leg ulcers (VLU). In such cases arterial recanalization is often recommended, and compression therapy is considered a contraindication when the ankle brachial pressure index (ABPI) is < 0.8. The aim of this study was to compare the outcome of patients with recalcitrant VLU, both without any arterial impairment ("pure venous recalcitrant leg ulcer" [pvRLU]) and with associated PAOD ("mixed arterial and venous recalcitrant leg ulcer" [mavRLU]), by treating only the venous disease. METHODS: The records of 180 outpatients with recalcitrant ulcers treated between January 2011 and July 2014 were reviewed retrospectively. In total, 109 were affected by pvRLU and 71 by mavRLU, with moderate PAOD defined by an ABPI between 0.5 and 0.8. In addition to the same local wound dressing, the patients received ultrasound guided foam sclerotherapy of the refluxing superficial veins and a modified inelastic compression with a pressure ≤ 40 mmHg. No patient was referred for arterial revascularization. The patients were followed until ulcer healing. RESULTS: Patients with pvRLU and mavRLU showed comparable demographic characteristics. Twenty-five patients were lost to follow up and the outcomes were analyzed in 93 patients with pVLU (85.4%) and in 62 patients with mavRLU (87.4%). The maximum time to complete healing was 48 weeks in the pvRLU group and 52 weeks in the mavRLU group (p = .009), The median healing time was 23 (pvRLU) versus 25.5 weeks (mavRLU) (p = .030). Deep venous incompetence (p < .001), ulcer surface area (p < .001), arterial disease (p = .002), and ulcer duration (p < .010) were risk factors for prolonged healing. CONCLUSION: Treatment of recalcitrant leg ulcers by treating venous incompetence by foam sclerotherapy and modified compression is successful, even if underlying moderate PAOD is not actively treated.

Adjustable Velcro Compression Devices are More Effective than Inelastic Bandages in Reducing Venous Edema in the Initial Treatment Phase: A Randomized Controlled Trial.

OBJECTIVE/BACKGROUND: The objective of this study was to compare the efficacy and comfort of inelastic bandages (IBs) and adjustable Velcro compression devices (AVCDs) in reducing venous leg edema in the initial treatment phase. METHODS: Forty legs from 36 patients with untreated venous edema (C3EpsAsdPr) were randomized to two groups. Patients in the first group received IBs (n = 20) and those in the second AVCDs (n = 20). Both compression devices were left on the leg day and night, and were renewed after 1 day. Patients in the AVCD group were asked to re-adjust the device as needed when it felt loose. Leg volume was calculated using the truncated cone formula at baseline (T0), after 1 day (T1) and after 7 days (T7). The interface pressure of the two compression devices was measured by an air filled probe, and the static stiffness index calculated after applying compression at T0 and T1, and just before removal of compression on T1 and T7. Patient comfort with regard to the two compression systems was assessed by grading signs and symptoms using a visual analog scale. RESULTS: At T1, the median percent volume reduction was 13% for the IB group versus 19% for the AVCD group; at T7 it was 19% versus 26%, respectively (p < .001). The pressure of the IBs was significantly higher compared with the AVCDs at T0 (63 vs. 43 mmHg) but dropped by > 50% over time, while it remained unchanged with AVCDs owing to the periodic readjustment by the patient. Comfort was reported to be similar with the two compression devices. CONCLUSION: Re-adjustable AVCDs with a resting pressure of around 40 mmHg are more effective in reducing chronic venous edema than IBs with a resting pressure of around 60 mmHg. AVCDs are effective and well tolerated, not only during maintenance therapy, but also in the initial decongestive treatment phase of patients with venous leg edema.

Compression for leg wounds.

The main points in this scholarly review on the use of compression therapy in leg ulcers are the different modes of action of this treatment and the tools that are available including their practical applicability and use for self management. Due to its effect of counteracting gravity, compression is also suggested for ulcers with aetiologies that are not usually thought to require compression. The clinical evidence reported in ulcer-healing studies are discussed and some considerations are made relating to the cost-effectiveness of this management. In general, the failures of compression therapy are not caused by poor compression material but due to poor knowledge and application techniques of the care providers. Future studies comparing different compression devices should also report details concerning the compression material used and the pressure exerted.

Sport socks do not enhance calf muscle pump function but inelastic wraps do.

AIM: Aim of the study was to measure the effect of elastic and inelastic compression on calf muscle pump function in healthy male athletes. METHODS: This was an experimental study which included 21 healthy male athletes. The ejection fraction (EF) of the venous calf pump was measured comparing the effects of a variety of compression materials: 1) sport compression stockings; 2) light zinc paste bandages; 3) sport compression stockings with additional Velcro® wraps over the calf. The influence of sport stocking and wraps on the venous calibre at the largest calf circumference in the lying and standing position was investigated using MRI. RESULTS: Inelastic compression exerting a median pressure in the standing position of 37.5 mmHg (zinc paste) and 48 mmHg (loosely applied straps over a sport stocking) achieved a significant increase of EF up to 100%. Sport stockings alone with a standing pressure of 19-24 mmHg did not show a significant change of EF. MRI demonstrated some venous narrowing in the lying but not in the standing position. By wrapping inelastic straps over the stocking an emptying of the veins in the lying and a considerable narrowing in the standing position could be observed. CONCLUSION: Venous calf pump function in athletes is not influenced by elastic sport stockings, but inelastic wraps either alone or applied over sport stockings lead to a significant enhancement.

Improvement of venous pumping function by double progressive compression stockings: higher pressure over the calf is more important than a graduated pressure profile.

BACKGROUND: Previous studies have shown that so-called progressive elastic compression stockings (PECS) with a negative pressure gradient have a more pronounced effect on venous pump function than conventional, graduated stockings. The aim of this study was to investigate the effect of higher graduated and non-graduated pressures on the venous calf pump in patients with venous disease. METHODS: The ejection fraction (EF) of the calf pump was measured by plethysmography under a standardized walking test in 20 patients suffering from chronic venous disease (CEAP C2-C5) without compression, (a) with one and (b) two PECS on top of each other, and (c) with one additional conventional stocking covering only the gaiter area to achieve a graduated high pressure profile. Interface pressure was measured in the gaiter area and on the calf. RESULTS: A significant improvement of EF compared with baseline was found with all three compression modalities. The two superimposed PECS, providing median pressures of 33 mmHg in the gaiter area and 46 mmHg at calf level, increased EF significantly up into the normal range. Increasing the gaiter pressure to 56 mmHg without changing the calf pressure did not result in further improvement. CONCLUSIONS: Two PECS applied on top of each other lead to a maximal improvement of the venous pump function, which cannot be further improved by increasing the pressure in the gaiter area thereby restoring a graduated pressure profile.

Diagnosis and treatment of primary lymphedema. Consensus document of the International Union of Phlebology (IUP)-2013.

Primary lymphedema can be managed effectively as a form of chronic lymphedema by a sequenced and targeted treatment and management program based around a combination of Decongestive Lymphatic Therapy (DLT) with compression therapy, when the latter is desired as an adjunct to DLT. Treatment in the maintenance phase should include compression garments, self-management, including self-massage, meticulous personal hygiene and skin care, in addition to lymphtransport-promoting excercises and activities, and, if desired, pneumatic compression therapy applied in the home. When conservative treatment fails, or gives sub-optimal outcomes, the management of primary lymphedema can be improved, where appropriate, with the proper addition of surgical interventions, either reconstructive or ablative. These two surgical therapies can be more effective when fully integrated with manual lymphatic drainage (MLD)-based DLT postoperatively. Compliance with a long-term commitment to MLD/DLT and particularly compression postoperatively is a critical factor in determining the success of any new treatment strategy involving either reconstructive or palliative surgery. The future of management of primary lymphedema has never been brighter with the new prospect of gene-and perhaps stem-cell oriented management.

Bandages or double stockings for the initial therapy of venous oedema? A randomized, controlled pilot study.

OBJECTIVE/BACKGROUND: Treatment for leg oedema conventionally starts with compression bandaging followed by elastic stockings once swelling is reduced. The aim was to investigate if a kit consisting of a liner and outer stocking, each exerting 20 mmHg of pressure, would be equally effective in achieving and maintaining volume reduction compared with short-stretch bandaging (2 weeks) followed by a class II (23-33 mmHg) stocking (2 weeks). METHODS: Forty legs (28 patients) with chronic venous oedema were randomised to either short-stretch bandages applied weekly for 2 weeks, followed by an elastic stocking for 2 weeks (group A) or a light stocking ("liner") for 1 week followed by superimposing a second stocking for 3 weeks (group B). Interface pressures and leg volumes were measured weekly. RESULTS: Despite differences in the pressure (median ± interquartile range) applied (bandage: 67 mmHg [55.7-73.0] vs. liner 24.5 mmHg [21.2-26.5]) volume reduction after 1 week was equal (12.8% [8.7-16.5] and 13.0% [10.4-20.6]). After 2 weeks (group A: 17.8% [10.6-20.0] vs. group B 16.2% [13.0-25.4]) and 4 weeks (group A: 17.3% [9.6-22.8] vs. group B: 17.0% [13.1-24.1]) volume reductions remained identical. CONCLUSIONS: The initial improvement in leg volume (1 week) was independent of the pressure applied and the reduction was maintained by superimposing a second stocking. This offers a simple alternative for managing leg oedema with reduced staffing costs.

Venous symptoms in C0 and C1 patients: UIP consensus document.

This UIP document provides an update on venous symptoms in CO and C1 patients. The correlation between venous symptoms and the presence of telangiectases and/or reticular veins is one of the most controversial topics in chronic venous disorders. As symptoms may be non-specific of chronic venous disease, it is important to differentiate venous symptoms from symptoms of other causes. Some data from the Bonn Vein Study suggest that the risk to develop venous symptoms is increased in women, advanced age and obesity. Treatment is based on physical advice, elastic compression, venoactive drugs, sclerotherapy, correction of foot static disorders and reduction of body weight. Future research should be promoted on venous symptoms in epidemiological and follow-up studies, about the relationship between female hormone levels and symptomatic telangiectasias, and between venous pain and foot static disorders in C0s C1s patients.

Occupational leg oedema is more reduced by antigraduated than by graduated stockings.

INTRODUCTION: Elastic compression stockings exerting a progressive pressure, higher at the calf than at the ankle (progressive elastic compression stockings, PECS), have already proved to be more comfortable, easier to put on and more effective in improving venous pumping function compared to graduated compression elastic stockings (GECS). Nevertheless, PECS could have a negative effect on the prevention and treatment of oedema or even favour oedema formation. The aim of the present study was to investigate if, in normal volunteers, PECS are able to prevent leg swelling during their working shift. METHODS: A total of 30 normal volunteers (14 males, 16 females aged 36.4 ± 6.6 years) staying standing or sitting during their shift were enrolled into the study. Their leg volume was measured at the beginning and at the end of their working shift on 2 consecutive days. On one day, the volunteers did not put on any stockings; on the other day, they wore GECS on one leg and PECS on the other. The difference between the leg volume measured at the end of the shift and the basal volume in the morning was called 'occupational oedema'. Interface pressure at points B1 and C was measured immediately after stockings' application and before removal. The volunteers were asked to report about difficulty of putting on the stockings and comfort during wearing time. The results were submitted to statistical analysis. RESULTS: The GECS and PECS groups had similar baseline leg volumes (3143 vs. 3154 ml) and occupational oedema (134 vs. 137.5 ml); after putting on the stockings, occupational oedema was reduced in both legs but the reduction was significantly greater with PECS (20 vs. 40 ml with GECS) (P < 0.05). Interface pressure at ankle level is higher with GECS both in supine and in standing position while at calf level it is higher with PECS both in supine and standing position. PECS are easier to put on and slightly more comfortable. CONCLUSION: PECS are easier to put on and more comfortable and produce a significantly higher reduction of occupational oedema compared with GECS in normal volunteers. Nevertheless leg volumetry, providing a global leg-volume evaluation, is not able to localise the oedema reduction and to assess if it occurs more in the calf or the ankle area. Theoretically, despite a global volume reduction, PECS could even promote a slight oedema formation at ankle level over-compensated by a greater oedema reduction at calf level. Further studies need to concentrate on patients with venous disease and on the local distribution of this global effect.
