Compression Stocking With 100% Donning and Doffing Success: An Open Label Randomised Controlled Trial.

OBJECTIVE: The aim of this study was to test whether an investigational two layer stocking exerting 27-29 mmHg pressure at the medial supramalleolar level, but without compression in the foot and heel, is easier to put on and take off than a standard stocking of the same compression class (23-32 mmHg), and also to assess the prevention of diurnal oedema with both types of stocking. METHODS: This was an open label randomised controlled trial, which included 47 patients. All participants were at least 65 years of age and suffered from chronic venous disease class C3 - C6 in one leg. The primary end point was donning success; secondary endpoints were doffing success, prevention of diurnal oedema over one day, and the comfort of wearing the stocking. Patients were randomly allocated to one of two groups. Both types of compression stocking were compared in each group for ease of donning and doffing in the manner of a crossover study. Subsequently, patients wore the stocking type assigned to their group for a whole day to evaluate comfort and the effect on diurnal leg volume. RESULTS: All participants were able to don the investigational stocking unaided, compared with 75% for the standard stocking (p < .001). Unaided removal success was 100% with the investigational stocking vs. 66% for the standard stocking (p < .001). There was no significant difference in leg volume reduction between the study groups after a day of wear. The investigational stocking was also rated as being more comfortable than the standard stocking (p < .001). CONCLUSION: The investigational stocking, which has no compression in the foot or heel area, is significantly easier to don and doff, with no inferiority in oedema prevention, compared with a standard stocking of the same compression class.

[Leg ulcers (ulcus cruris): The frequent macrovascular causes]. / Ulcus cruris: Die häufigen, makrovaskulären Ursachen.

Leg ulcers (ulcus cruris): The frequent macrovascular causes Abstract. Four pathologies make up the macrovascular etiologies of leg uclers: Venous leg ulcers (50 %), mixed venous-arterial leg ulcers (20 %), arterial leg ulcers (5 %), and Martorell hypertensive ischemic leg ulcer (5 %). The remaining 20 % concern a large array of other etiologies. Every leg ulcer requires vascular (arterial and venous) work-up, that can be completed with microbiology, biopsy, and more in-depth internal diagnostics, as indicated. Venous leg ulcers are treated with compression therapy. Incompetent saphenous veins and tributaries are abolished if the deep venous system is patent. Occluded iliac veins are recanalised and stented, as possible. Refractory venous leg ulcers are grafted with split skin or punch grafts, depending on their surface. Extensive dermatolipofasciosclerosis may be tangentially removed by shave therapy or fasciectomy, that can be combined with negative pressure wound treatment (NPWT). Skin equivalents are an alternative to treat superficial venous leg ulcers that fail to epithelialise. Their indication in the treatment of more complex leg ulcers still needs to be better investigated and understood. The use of dermal matrices leads to more stable scars. Mixed venous-arterial leg ulcers heal slower and recur more frequently. Compression needs to be reduced. Refractory cases require arterial revascularisation, to transform the mixed venous-arterial into a venous leg ulcer. Arterial leg ulcers require arterial revascularization and split skin graft. Martorell hypertensive ischemic leg ulcer is still underrecognised and often confounded with with pyoderma gangrenosum, which leads therapy into a wrong direction. Necrosectomy, antibiotic treatment in the presence of relevant bacterial superinfection, and repeated split skin grafts eventually heal the vast majority of these extremely painful and potentially mortal wounds.

How we started performing endovenous thermal ablation procedures: a personal history.

This story is a personal journey of two Dutch dermatologists pioneering in the field of endovenous laser ablation of varicose veins, illustrating how innovations find their way in medicine and, in particular, in surgical specialties. After the introduction of these thermal ablative procedures in 2001, we have fully embraced these minimally invasive techniques, and in the process, we have increased our understanding on its mechanism of action and confirmed the clinical relevance of treating varicose veins with endovenous laser ablation. In 2013, thermal ablation is considered a standard of care by physicians as well as patients with varicose veins.

Comparing endovenous laser ablation, foam sclerotherapy, and conventional surgery for great saphenous varicose veins.

BACKGROUND: Many case series have been published on treatments of varicose veins, but comparative randomized controlled trials remain sparse. OBJECTIVE: To compare the anatomic success rate, frequency of major complications, and quality-of-life improvement of endovenous laser ablation (EVLA), ultrasound-guided foam sclerotherapy (UGFS), and conventional surgery (CS), after 1-year follow-up. METHODS: A total of 240 consecutive patients with primary symptomatic great saphenous vein reflux were randomized to EVLA, UGFS, or CS, consisting of high ligation and short stripping. Primary outcome was anatomic success defined as obliteration or absence of the treated vein on ultrasound examination after 1 year. Secondary outcomes were complications, improvement of the "C" class of the CEAP classification, and improvement of disease-specific (Chronic Venous Insufficiency Quality-of-Life Questionnaire) and general (EuroQol 5) quality-of-life scores. RESULTS: More than 80% of the study population was classified as C2 or C3 venous disease. After 1 year, the anatomic success rate was highest after EVLA (88.5%), followed by CS (88.2%) and UGFS (72.2%) (P < .001). The complication rate was low and comparable between treatment groups. All groups showed significant (P < .001) improvement of EuroQol 5 and Chronic Venous Insufficiency Quality-of-Life Questionnaire scores after therapy; 84.3% of all treated patients showed an improvement of the "C" of the CEAP classification. CONCLUSIONS: After 1-year follow-up, EVLA is as effective as CS and superior to UGFS according to occlusion on ultrasound duplex. Quality of life improves after treatment in all groups significantly.

Duplication of the great saphenous vein: a definition problem and implications for therapy.

BACKGROUND: In the literature there is a range from 1% to 20 % of duplication (up to 20%) of the great saphenous vein (GSV) reported, because there is a lack of an accurate definition of the GSV and objective parameters for an anatomical identification. OBJECTIVE: To investigate the frequency of true duplications of the GSV. MATERIALS AND METHODS: A systematic review of the literature, a retrospective analysis of duplex examinations, and a prospective study of duplex examinations to investigate the frequency of true duplications of the GSV. RESULTS: In the literature review, a great variety of definitions is used for duplication of the GSV. Before the consensus of the Union International de Phlébologie (UIP) in 2006, Only in a small number of studies, the definition of the GSV in the saphenous compartment between the fascial blades is mentioned. CONCLUSION: Phlebographic studies have been the criterion standard for the identification of venous anatomy. Now, duplex is regarded as the criterion standard for accurate detection of the veins. True duplication of the GSV is less common than the previous literature has suggested, namely 1.6% to 2%. It is recommended that the duplicated GSV should be treated to avoid an important risk of recurrence of venous insufficiency.

Heat conduction from the exceedingly hot fiber tip contributes to the endovenous laser ablation of varicose veins.

Lower-extremity venous insufficiency is a common condition, associated with considerable health care costs. Endovenous laser ablation is increasingly used as therapy, but its mechanism of action is insufficiently understood. Here, direct absorption of the laser light, collapsing steam bubbles and direct fiber-wall contact have all been mentioned as contributing mechanisms. Because fiber tips have reported temperatures of 800-1,300 degrees C during endovenous laser ablation, we sought to assess whether heat conduction from the hot tip could cause irreversible thermal injury to the venous wall. We approximated the hot fiber tip as a sphere with diameter equal to the fiber diameter, having a steady state temperature of 800 degrees C or 1,000 degrees C. We computed venous wall temperatures due to heat conduction from this hot sphere, varying the pullback velocity of the fiber and the diameter of the vein. Venous wall temperatures corresponding to irreversible injury resulted for a 3 mm diameter vein and pullback velocities <3 mm/s but not for 5 mm and > or =1 mm/s. The highest wall temperature corresponded to the position on the wall closest to the fiber tip, hence it moves longitudinally in parallel with the moving fiber tip. We concluded that heat conduction from the hot fiber tip is a contributing mechanism in endovenous laser ablation.

Minimally invasive techniques in the treatment of saphenous varicose veins.

Lower extremity venous insufficiency is common and increases with age. In addition to classical symptoms, it may result in skin changes and venous ulcers. Chronic venous insufficiency has a great impact on patients' health-related quality of life and is associated with considerable health care costs. Surgical ligation of the junction with or without stripping has been the standard of care in the treatment of insufficient great and small saphenous veins. However, the recurrence rates are relatively high and surgery may be associated with serious adverse events and considerable down time; it is also cosmetically suboptimal. To improve efficacy, patients' health-related quality of life and treatment satisfaction and to reduce serious side effects, costs, and postoperative pain, several minimally invasive techniques have been introduced in the last decade. Dermatologists have played an important role in the development of these new therapies of truncal varicose veins. Of the new therapies, ultrasound-guided foam sclerotherapy, endovenous laser therapy, and radiofrequency ablation are the most common and challenge surgery as the "gold standard" of care for patients with varicose veins. The objective of this review is to inform clinicians about these 3 therapeutic options for truncal varicose veins and to describe and compare the procedures, indications, efficacy, and safety profile.

Endovenous therapies of lower extremity varicosities: a meta-analysis.

BACKGROUND: Minimally invasive techniques such as endovenous laser therapy, radiofrequency ablation, and ultrasound-guided foam sclerotherapy are widely used in the treatment of lower extremity varicosities. These therapies have not yet been compared with surgical ligation and stripping in large randomized clinical trials. METHODS: A systematic review of Medline, Cochrane Library, and Cinahl was performed to identify studies on the effectiveness of the four therapies up to February 2007. All clinical studies (open, noncomparative, and randomized clinical trials) that used ultrasound examination as an outcome measure were included. Because observational and randomized clinical trial data were included, both the Meta-analysis Of Observational Studies in Epidemiology (MOOSE) and Quality Of Reporting Of Meta-analyses (QUORUM) guidelines were consulted. A random effects meta-analysis was performed, and subgroup analysis and meta-regression were done to explore sources of between-study variation. RESULTS: Of the 119 retrieved studies, 64 (53.8%) were eligible and assessed 12,320 limbs. Average follow-up was 32.2 months. After 3 years, the estimated pooled success rates (with 95% confidence intervals [CI]) for stripping, foam sclerotherapy, radiofrequency ablation, and laser therapy were about 78% (70%-84%), 77% (69%-84%), 84% (75%-90%), and 94% (87%-98%), respectively. After adjusting for follow-up, foam therapy and radiofrequency ablation were as effective as surgical stripping (adjusted odds ratio [AOR], 0.12 [95% CI, -0.61 to 0.85] and 0.43 [95% CI, -0.19 to 1.04], respectively). Endovenous laser therapy was significantly more effective compared with stripping (AOR, 1.13; 95% CI, 0.40-1.87), foam therapy (AOR, 1.02; 95% CI, 0.28-1.75), and radiofrequency ablation (AOR, 0.71; 95% CI, 0.15-1.27). CONCLUSION: In the absence of large, comparative randomized clinical trials, the minimally invasive techniques appear to be at least as effective as surgery in the treatment of lower extremity varicose veins.

Systemic and topical drugs for aging skin.

The rejuvenation of aging skin is a common desire for our patients, and several options are available. Although there are some systemic methods, the most commonly used treatments for rejuvenation of the skin are applied topically. The most frequently used topical drugs include retinoids, alpha hydroxy acids (AHAs), vitamin C, beta hydroxy acids, anti-oxidants, and tocopherol. Combination therapy is frequently used; particularly common is the combination of retinoids and AHAs. Systemic therapies available include oral retinoids and vitamin C. Other available therapies such as chemical peels, face-lifts, collagen, and botulinum toxin injections are not discussed in this article.
