The postthrombotic syndrome (PTS) is a frequent complication of deep venous thrombosis (DVT). Clinically, PTS is characterized by chronic, persistent pain, swelling, and other signs in the affected limb. Rarely, ulcers may develop. Because of its prevalence, severity, and chronicity, PTS is burdensome and costly. Preventing DVT with the use of effective thromboprophylaxis in high-risk patients and settings and minimizing the risk of ipsilateral DVT recurrence are likely to reduce the risk of development of PTS. Daily use of compression stockings after DVT might reduce the incidence and severity of PTS, but consistent and convincing data about their effectiveness are not available. Future research should focus on standardizing diagnostic criteria for PTS, identifying patients at high risk for PTS, and rigorously evaluating the role of thrombolysis in preventing PTS and of compression stockings in preventing and treating PTS. In addition, novel therapies should be sought and evaluated.
The Egyptian civilisation is one of the oldest in history and was renowned for its scientific and artistic achievements, and medicine was no exception. The ancient Egyptians were masters in applying and arranging bandages, and they recognized the cardinal signs of infection and inflammation. Egyptian drug therapy can be regarded as having evolved from a system rooted in magic and empirical observation. To illustrate how the Egyptian wound healing methods provided a major stimulus for the development of surgery, we conducted a literature search.
OBJECTIVE: To compare performance of four commercial four-layer bandage systems when applied to the leg. METHODS: Four experienced bandagers applied each system: [Profore Regular (Smith and Nephew); Ultra-Four (Robinson); System 4 (Seton) and K Four (Parema)] to the same leg. Bandages were applied as single layers and as completed systems using standard techniques. For each application, 18 pressure measurements were taken using the Borgnis Medical Stocking Tester (MST) at three measuring points (ankle, gaiter and mid-calf) on medial and lateral aspects in three postures: (horizontal, standing and sitting). RESULTS: In all 2304 observations were made, 576 for each bandager, 576 for each bandaging system, 768 for each measuring point, 1152 for each aspect and 768 for each posture. The increase in pressure produced by each additional layer was 65-75% of the pressure of the same bandage when used as a single layer. There were significant differences in the final pressures achieved by the bandagers (means: 45-54 mmHg, p<0.001) and between bandage systems (means: System 4: 46 mmHg, Profore: 47 mmHg, K Four: 52 mmHg, Ultra-Four: 54 mmHg; p=0.005). The relationships between the final pressures achieved at each of the three measuring points, the three postures and the two aspects were not consistent among the bandage systems (p<0.01). CONCLUSIONS: When a bandage is applied as part of a multi-layered system it exerts approximately 70% of the pressure exerted when applied alone, thus challenging the commonly-held assumption that the final pressure achieved by a multi-layer bandaging system is the sum of the pressures exerted by each individual layer. Each of the four bandaging systems exerted different final pressures and gradients and different changes with posture change. These differences have important implications, which could influence the selection (or avoidance) of a particular bandage system according to a patient's condition and circumstances.
