Clinical validation of a specially sized class II compression knee-sock for the prevention of recurrent ulcers in patients with chronic venous stasis (CEAP 5).

AIM: Patients cured of venous ulcers (VU) often suffer recurrences if they do not wear elastic compression hosiery. Unfortunately, only half of them can benefit of this treatment, because their leg proportions have changed, obliging them to order to measure products which are harder to find, and expensive. This study was designed to validate a class II elastic knee-sock (GGG-Ral standards) manufactured on the basis of the ankle and calf circumferences of recently cured patients. METHODS: In all, 177 consecutive patients were given a sock that fitted properly, to be worn for 30 days. Numerical and analogue symptom scales and a questionnaire on clinical improvement have been used to evaluate treatment benefits. RESULTS: Symptom improvements reached respectively 68% and 65% and clinical improvements 96% of the patients. Compliance was 91.6%. CONCLUSIONS: Specially-sized elastic hose for patients cured of VU would serve to treat the large numbers who cannot use routine-production sizes, with improvements in compliance and clinical symptoms.

Deep vein thrombosis: a mininvasive locoregional thrombolytic treatment.

AIM: Locoregional thrombolytic therapy has emerged in the last years as the treatment of choise for iliofemoral deep vein thrombosis, preserving the structural and functional integrity of vein walls. We studied the efficacy and complication rates of direct regional thrombolytic therapy in acute venous thrombosis of lower extremities. METHODS: Between January 2002 and March 2007, 8 selected patients with acute extensive and symptomatic iliofemoral or femoral-popliteal venous thrombosis were treated with flow-direct regional thrombolytic therapy. We used a direct regional infusion of urokinase into the deep venous system ( 100.000 U al presentation, then 75.000 U/ h) from an ipsilateral dorsal foot vein . Simultaneously the superficial venous system was collapsed with elastic limb compression while administering subtherapeutic heparin doses of 300-400 U/h. All patients underwent routine venous duplex imaging at day 1, 2, 30 and after 3, 6 and 12 months. Data including clinical conditions and laboratory values (fibrinogen, hematocrit, haemoglobin, platlets and prothrombin time) were obtained throughout the infusion time. Results. Procedural success was achieved in all patients (100%). Complete recanalization, patency and continence of venous system documented at the echocolorDoppler control, were obtained in 48 hours, with symptom remission. Mean infusion time was 37.5 hours (28-48 hours). Neither major bleeding complications nor pulmonary embolisms occurred during the treatment. At day 30 venous patency and incontinence and long-term symptom resolution were achieved in all patients, as well as at 3, 6 and 12 months. CONCLUSIONS: Loco-regional thrombolytic therapy is safe and effective in selected patients and may become a well-founded alternative in the treatment of acute deep vein thrombosis of lower extremities and in the prevenction of its complications .

Evaluation of SurePress Comfort: a new compression system for the management of venous leg ulcers.

OBJECTIVE: The primary aim was to compare the healing of venous leg ulcers after management with either a new compression stocking (SurePress Comfort, ConvaTec) or a standard short-stretch bandage system (Comprilan, BSN Medical GmbH & Co). Secondary parameters included healing rate, ease of application and removal, comfort during wear, local pain levels and concordance. METHOD: This was a prospective multicentre open-label comparative randomised controlled parallel-group pilot trial of 12 weeks' duration. RESULTS: The proportion of ulcers that healed in 12 weeks (44.4% versus 17.2%, p=0.027) and the average time to healing (72 +/- 5 days versus 101 +/- 7 days, p=0.0265) were significantly better with SurePress Comfort than the comparator. All the secondary parameters (except concordance) also showed statistically significant differences for the stocking over the comparator. CONCLUSION: SurePress Comfort stocking system is more effective than a standard short-stretch compression bandage in healing venous leg ulcers and in reducing associated pain. It is well accepted by patients due to its ease of use and comfort, and its safety profile is comparable to that of a standard compression system. It may therefore provide an effective solution for the delivery of graduated compression and has the potential to improve concordance, compared with short- stretch bandages. DECLARATION OF INTEREST: This study was sponsored by ConvaTec.

A randomised controlled study of four-layer compression versus Unna's Boot for venous ulcers.

OBJECTIVE: This study set out to compare healing rates, handling properties and patient comfort of a four-layer bandage system (Profore) and Unna's Boot in the treatment of venous leg ulcers. METHOD: This was a prospective randomised parallel-group trial. Patients with venous leg ulcers from four centres in Italy were randomised to receive treatment with either Unna's Boot or Profore. Time to healing was recorded for a maximum of 24 weeks. Pain was assessed using a visual analogue scale. Staff assessed ease of application, while patients rated comfort. RESULTS: Data were available for 68 patients with 68 wounds. At 24 weeks complete healing was seen in 74% of the Profore group compared with 66% of the Unna's Boot group. The median time spent in the study was 50 days (range: 7-175 days), corresponding to 51 days (range: 7-175 days) for Profore patients and 49 days (range: 7-168 days) for Unna's Boot patients. There was no difference (p = 0.13) between the groups in time to closure. Overall, more Profore than Unna's Boot applications were rated as excellent. There was a significant difference, in favour of Profore, in ease of application at the final application (p = 0.013). At the initial application, there was a significant difference in bandage appearance (p = 0.04), again favouring Profore, but this was not sustained at the final application (p = 0.18). CONCLUSION: Profore is as effective as Unna's Boot in the treatment of venous leg ulcers.

Stroke is the third most common cause of death in the occidental population and most important cause of disability. The average annual incidence of cerebral ischemia is increasing linked to population's mean age that is growing together with risk factors for cerebrovascular disease. There are many multicentre randomised trials (NASCET, ECST, Vet. Adm. SCT, CASANOVA, ACSV Adm. Study, ACAS, ACST) that identify surgical therapy as a prevention for stroke in symptomatic and asymptomatic patients. In discussing about all these studies it appears the necessity to follow the surgical guide-line proposed by multicentre trials in order to uniform indications for surgical or conservative therapy and to obtain data and results good enough to be effective in preventing really efficaciously stroke.

Incompetent perforating veins subfascial ligation as an important adjunct to venous surgery of the lower extremities: evaluation of surgical results.

The role of incompetent perforating veins in chronic venous disease is well established. The determination of hemodynamic alterations and perforating veins location is evaluated by physical examination, phlebography and ultrasonography. All patients with perforating veins failure underwent surgical treatment. From 1971 to 1982, 6000 patients with lower limbs primary varicose veins underwent surgical treatment: 510 more patients were hospitalized for post-thrombotic disease. In 6% of patients suffering from primary varicose veins, in 18% with recurrent varicose veins and in 76% with secondary veins (8.1% of all patients), subfascial ligation of incompetent perforating veins was associated with complete vein stripping. Incompetent perforating vein ligation alone was performed in 0.6% of cases. The technique is based on subfacial ligation of perforating veins through a small skin incision (2.3 cm). This procedure allows a fast healing of surgical wounds and a good esthetical result. The subfacial ligation allows a complete cure of the disease in primary varicose veins and avoids the main causes of recurrence. Moreover in the post-thrombotic disease treated by this procedure, symptoms and trophic lesions are markedly decreased and a dramatic reduction in the ulceration rate, 62.5% to 15% at ten year follow-up, is achieved.
