In a crossover study designed to judge the efficacy of the topical polymeric starch iodophore, cadexomer iodine, in accelerating the healing of venous stasis ulcers, 75 patients were prospectively randomly assigned to receive either cadexomer iodine or standard treatment. The control treatment consisted of a standard saline wet-to-dry compressive dressing. The patients improved with either treatment: ulcers healed more than twice as rapidly using cadexomer iodine (n = 38) as with standard therapy (n = 37) (P = .0025). Ulcers treated with cadexomer iodine showed trends toward less pain, exudate, pus, and debris, and a more rapid development of granulation tissue. Twelve patients crossed over from control treatment to the use of cadexomer iodine because of a failure to heal, but no patients switched to control therapy from the use of cadexomer iodine (P = .01). Except for occasional mild local burning in wounds treated with cadexomer iodine, no adverse effects were noted with either regimen.

This preliminary study investigates the use of a radiant-heat bandage, Warm-Up Active Wound Therapy, as a new approach to the treatment of patients with chronic venous ulcers. Thirteen patients were randomly assigned to either conventional therapy or Warm-Up Active Wound Therapy for inpatient treatment of chronic venous stasis ulcers. Our results indicated that Warm-Up Active Wound Therapy is more effective than conventional therapy in healing chronic venous ulcers, and patients reported a significant reduction in wound pain. Warm-Up Active Wound Therapy also was found to be a safe treatment modality with no adverse events occurring in any patient.

A noncontact radiant heat bandage was used for the treatment of chronic venous stasis ulcers (mean duration 4.44 years) in inpatients who had failed aggressive inpatient and outpatient conventional therapy. The noncontact radiant heat bandage was placed over the ulcer for 5 hours daily: three 1-hour heating periods separated by two 1-hour nonheating periods during this 2-week trial. Wound size, status, and pain severity were recorded for each patient. A total of 17 patients with 31 total wounds were enrolled. No adverse effects were noted in any patient. There was improvement in 14/17 total patients during the 2-week inpatient trial and 8/17 patients healed completely after discharge. There was 1 recurrence during an 18-month follow-up. Pain scores were improved in most patients after the bandage was applied. The use of a noncontact radiant heat bandage is a safe and efficacious inpatient therapy for the management of chronic venous stasis ulcers in patients who have failed conventional therapy.

Although elderly patients have physiologic impairments in wound healing, their wounds should be expected to heal with the same frequency of closure as those in younger populations, albeit at a slower rate. However, compared to the general population, the elderly population has a higher incidence of chronic wounds: diabetic foot ulcers, pressure ulcers, and venous stasis ulcers. Experimental and clinical data indicate physiologically impaired healing is characterized by decreased angiogenesis and synthesis of critical growth factors. Further, compared to younger populations, the elderly have a higher rate of mortality associated with specific morbidities, such as sepsis and acute respiratory distress. As these morbidities may develop directly from the wound, early intervention is mandated. In this report, 40 consecutive elderly patients (65-102 years old) with chronic wounds were analyzed. All patients were provided the same treatment protocol and healing was defined as 100% epithelization and no drainage. Despite the wounds presenting in a nonhealing and/or infected state, 73% of these chronic wounds in elderly patients healed. This suggests that elderly patients with diabetic foot ulcers, pressure ulcers, and venous stasis ulcers close their wounds at a similar frequency as younger patients. Therefore, early intervention and comprehensive treatment that includes safe topical therapies, in addition to growth factors and cellular therapy used for chronic wounds, ensure these patients will be spared the morbidities of pain, amputation, osteomyelitis, and even death. We hypothesize that if all elderly patients with chronic wounds are provided early treatment, morbidities (e.g., amputation, sepsis, pain) and associated costs will decrease.

Pain must be managed during treatment of a patient with a chronic wound. Failure to do so will impair the patient's ability to heal significantly. Understanding the wound's etiology is essential for designing the wound-healing protocol and implementing its pain management regimen, of which a critical part is the chronic-wound patient's self-assessed scores of pain and functionality. In this report we present a paradigm for treating all chronic wounds, which was subsequently applied to 32 consecutive patients. Our integrated-team approach to managing the treatment of wounds includes accurate evaluation of the progression of patients' pain. Directors of the pain-management team and wound team have jointly managed hundreds of patients--either hospitalized or seen in both outpatient clinical practices. The three general categories for etiologies of the 10 most common types of chronic wounds are: ischemia, neuropathy, and direct tissue damage (e.g. pressure ulcers and venous stasis ulcers). Each of these are treated with unique analgesic regimens focused on surgical/medical management of the wound: oral and parenteral medications in combinations designed to facilitate specific additive analgesic effects and nerve blocks and implantable devices for correcting underlying wound pathophysiology. Successful treatment of pain generally results in increased functional independence and improvement of the patient's quality of life. We integrated wound-care pain-management team established guidelines that delineate the causes of chronic wounds and categorize treatment options for practical clinical use. The expectation is that all pain should be resolved in all patients if both the wound-healing and pain-healthcare providers use current technologies and drugs.

The history of surgery is rich with accomplishments in wound care, a legacy that recently has been abandoned by many surgeons only to be taken up by nonsurgical providers. When dealing with advanced wounds at the end of life, such as pressure ulcers or venous stasis ulcers, goals of treatment are relief of pain, elimination of odor, and control of wound exudates and infection. Benefits and risks of surgical intervention must be discussed with the patient and family in terms of the patient's perceived prognosis, extent of tissue necrosis and infection, the rate of deterioration, and the underlying wound pathogenesis. When appropriate, the role of surgery looms large in the treatment of chronic, advanced wounds, especially when minimally invasive surgical techniques are used.

The central portion of chronic wounds is often hypoxic and relatively hypothermic, representing a deficient energy supply of the tissue, which impedes wound healing or even makes it impossible. Water-filtered infrared-A (wIRA) is a special form of heat radiation with a high tissue penetration and a low thermal load to the skin surface. wIRA produces a therapeutically usable field of heat and increases temperature, oxygen partial pressure and perfusion of the tissue. These three factors are decisive for a sufficient tissue supply with energy and oxygen and consequently as well for wound healing, especially in chronic wounds, and infection defense. wIRA acts both by thermal and thermic as well as by non-thermal and non-thermic effects. wIRA can advance wound healing or improve an impaired wound healing process and can especially enable wound healing in non-healing chronic wounds. wIRA can considerably alleviate the pain and diminish wound exudation and inflammation and can show positive immunomodulatory effects.In a prospective, randomized, controlled study of 40 patients with chronic venous stasis ulcers of the lower legs irradiation with wIRA and visible light (VIS) accelerated the wound healing process (on average 18 vs. 42 days until complete wound closure, residual ulcer area after 42 days 0.4 cm(2) vs. 2.8 cm(2)) and led to a reduction of the required dose of pain medication in comparison to the control group of patients treated with the same standard care (wound cleansing, wound dressing with antibacterial gauze, and compression garment therapy) without the concomitant irradiation. Another prospective study of 10 patients with non-healing chronic venous stasis ulcers of the lower legs included extensive thermographic investigation. Therapy with wIRA(+VIS) resulted in a complete or almost complete wound healing in 7 patients and a marked reduction of the ulcer size in another 2 of the 10 patients, a clear reduction of pain and required dose of pain medication, and a normalization of the thermographic image. In a current prospective, randomized, controlled, blinded study patients with non-healing chronic venous stasis ulcers of the lower legs are treated with compression garment therapy, wound cleansing, wound dressings and 30 minutes irradiation five times per week over 9 weeks. A preliminary analysis of the first 23 patients of this study has shown in the group with wIRA(+VIS) compared to a control group with VIS an advanced wound healing, an improved granulation and in the later phase of treatment a decrease of the bacterial burden. Some case reports have demonstrated that wIRA can also be used for mixed arterial-venous ulcers or arterial ulcers, if irradiation intensity is chosen appropriately low and if irradiation is monitored carefully. wIRA can be used concerning decubital ulcers both in a preventive and in a therapeutic indication. wIRA can improve the resorption of topically applied substances also on wounds. An irradiation with VIS and wIRA presumably acts with endogenous protoporphyrin IX (or protoporphyrin IX of bacteria) virtually similar as a mild photodynamic therapy (endogenous PDT-like effect). This could lead to improved cell regeneration and wound healing and to antibacterial effects. In conclusion, these results indicate that wIRA generally should be considered for the treatment of chronic wounds.

Water-filtered infrared-A (wIRA), as a special form of heat radiation with a high tissue penetration and a low thermal load to the skin surface, can improve the healing of acute and chronic wounds both by thermal and thermic as well as by non-thermal and non-thermic effects. wIRA increases tissue temperature (+2.7 degrees C at a tissue depth of 2 cm), tissue oxygen partial pressure (+32% at a tissue depth of 2 cm) and tissue perfusion. These three factors are decisive for a sufficient supply of tissue with energy and oxygen and consequently also for wound healing and infection defense. wIRA can considerably alleviate pain (without any exception during 230 irradiations) with substantially less need for analgesics (52-69% less in the groups with wIRA compared to the control groups). It also diminishes exudation and inflammation and can show positive immunomodulatory effects. The overall evaluation of the effect of irradiation as well as the wound healing and the cosmetic result (assessed on visual analogue scales) were markedly better in the group with wIRA compared to the control group. wIRA can advance wound healing (median reduction of wound size of 90% in severely burned children already after 9 days in the group with wIRA compared to 13 days in the control group; on average 18 versus 42 days until complete wound closure in chronic venous stasis ulcers) or improve an impaired wound healing (reaching wound closure and normalization of the thermographic image in otherwise recalcitrant chronic venous stasis ulcers) both in acute and in chronic wounds including infected wounds. After major abdominal surgery there was a trend in favor of the wIRA group to a lower rate of total wound infections (7% versus 15%) including late infections following discharge from hospital (0% versus 8%) and a trend towards a shorter postoperative hospital stay (9 versus 11 days). Even the normal wound healing process can be improved. The mentioned effects have been proven in six prospective studies, with most of the effects having an evidence level of Ia/Ib.wIRA represents a valuable therapy option and can generally be recommended for use in the treatment of acute as well as of chronic wounds.

Pulsed radio frequency energy (PRFE) has successfully been used to treat diabetic and venous stasis ulcers. In this case report, a lightweight wearable form of a PFRE device was evaluated and used to treat three diabetic foot ulcers and one venous stasis ulcer. The ulcers were present on the four patients for more than 3 months and had failed to heal after conventional treatment. A lightweight battery-powered, wearable form of PRFE device was introduced as a treatment and used 6-8 hours per day for a period of 6 weeks. All patients after 1 week of therapy showed improvement and wound size was seen to decrease. Patient 1 had a venous stasis ulcer, and reported significant pain relief after 2 weeks treatment. Patients 2 and 3 achieved complete healing after 3 weeks treatment, and patients 1 and 4 had a 95% and 88% reduction in wound size, respectively, after the 6-week study period. Both these patients continued to complete healing using the PRFE device after the 6-week study period. PRFE treatment delivered in the form of a wearable lightweight patch appears to offer promise in the treatment of recalcitrant chronic wounds.

May-Thurner syndrome (MTS) is an anatomically variable condition of venous outflow obstruction caused by extrinsic compression. Although this syndrome is rare, its prevalence is likely underestimated. The pathology of this condition is secondary to a partial obstruction of the common iliac vein by an overlying common iliac artery with subsequent entrapment of the left common iliac vein. Regardless of the mechanism, this causes partial or complete impedance to the iliac vein outflow with subsequent possible obstruction and extensive ipsilateral deep vein thrombosis (DVT) of the ipsilateral extremity. Clinical presentations include, but are not limited to pain, swelling, venous stasis ulcers, and skin discoloration. With extensive DVT, postphlebetic syndrome, with all of its sequelae, may also develop. Treatment is based on the clinical presentation and includes staged thrombolysis with/without prophylactic retrievable inferior vena cava filter placement, followed by angioplasty/stenting of the left iliac vein in MTS patients with extensive DVT. This review highlights the variable presentations of MTS and outlines possible management within the current Society for Vascular Surgery consensus.
