Chronic venous insufficiency and venous microangiopathy: management with compression and Pycnogenol®.

BACKGROUND: The aim of this prospective supplement summer registry study was to evaluate the efficacy of Pycnogenol® in controlling symptoms of chronic venous insufficiency (CVI) and microcirculatory parameters: venous hypertension and microangiopathy. Pycnogenol® (Horphag Research) is the standardized extract of the bark of Pinus Pinaster. METHODS: During the summer period between June and August 142 patients were split into three groups: 1) Pycnogenol® 150 mg/day; 2) compression stockings; 3) and compression + Pycnogenol®. RESULTS: Venous pressure (ambulatory venous pressure, AVP) and refilling time (RT), microcirculatory and clinical measurements were comparable at inclusion. At 8 weeks variations in skin flux (RF), rate of ankle swelling (RAS), skin PO2-PCO2, Analogue Symptomatic Score (ASLS), Venous Disability and severity Scores and local oxidative stress (OS) indicated a statistically significant improvement by Pycnogenol® both as a single supplement and in association with compression in comparison with baseline. Pycnogenol® significantly improved the microcirculation in comparison with compression (P<0.05). The combined effects of Pycnogenol+compression produced the best results in most measurements. The summer study penalized compression - in a very hot summer - with many drops out. No side effects due to supplementation were observed; tolerability was optimal. The tolerability to stocking was less than optimal (70% of compression not correctly used). Pycnogenol® alone was more effective than compression alone. The increase (P<0.05) in skin O2 and the decrease in PCO2 were associated with the decrease in skin flux. The variations in capillary filtration (RAS) were the most important microcirculation changes. RAS is directly associated with swelling, the hallmark of CVI. Pycnogenol® in both Pycnogenol groups significantly improved RAS in comparison with compression only (P<0.05). The decrease in OS in both Pycnogenol® groups was significant in comparison with compression only (P<0.05). A lower OS is an important micro-metabolic indication of a better capillary bed with better nutritional, perfusional exchanges. The clinical measurements followed the patterns of the microcirculation with the supplement groups performing statistically better (P<0.002) than the compression-only. CONCLUSIONS: This "summer registry" study confirms the clinical and microcirculatory efficacy of Pycnogenol in CVI and venous microangiopathy. The study indicates the significant clinical role of Pycnogenol® (both as a single treatment and in association with compression) in the management, treatment and control of this common clinical problem.

Superficial venous incompetence: low-cost outpatient minisurgery, sclerotherapy and combined procedure as a management plan. Costs and efficacy. A 20-year, follow-up registry.

BACKGROUND: This registry study evaluated low-cost outpatient surgery (mini-S) for venous insufficiency as an alternative to stripping. METHODS: This 20-year follow-up is focused on the recurrence of varices and on the long-term efficacy of the mini-S (group 1) in comparison with controls (2, stripping), sclerotherapy (3) or a combination of mini-S+sclerotherapy (4). Costs were compared. RESULTS: At 20-years of follow-up, considering recurrence/development of new varicose veins, 24.05% of the limbs treated with mini-S developed new varices in comparison with 64.4% in group 2, 24.1% in group 3 and 15.4% in group 4 (P<0.05). New surgical procedures were needed in 18.9% of mini-S patients vs. 58.5% in group 2, 21.9% in group 3 and 19.7% in group 4 (P<0.05 between group 2 and the other groups). Sclerotherapy (in the years following the initial treatment) was used in 37.9% of mini-S patients in comparison with 67.7% of subjects in group 2 patients, 33.1% in group 3 and 22.8% in group 4 (P<0.05 between outpatient treatment and group 2). The superficial venous system was incompetent in 21% of mini-S patients in comparison with 38.8% in group 2 (P<0.05), 20.7% in group 3 and 17.9% of group 4. At 20 years edema was present in 10.5% of limbs in group 2 in comparison with a <3% (range 2.2-2.1%) in the other groups. Edema was more significant after stripping. Ambulatory venous pressure measurements in subgroups was lower in groups 1, 3 and 4 with a lower refilling time (P<0.05). The cost of in-hospital, daily surgical treatments were €1978 (covered by the heathcare provider). The cost of mini-S was on average €488 per limb (covered by patients). CONCLUSIONS: Outpatients procedures, in particular the mini-S management plan, were cheaper than stripping and more effective at 20-years follow-up. They could be a model for emerging contries with restricted budgets for vein surgery. Also being cheaper more people may have benefits from treatment when/where hospital procedures are not covered by an healthcare provider.

Phlebology is not a specialty for its own in Italy. Phlebological patients are treated by vascular and general surgeons, dermatologists, phlebologists, angiologists, internists and even general practitioners. Even tough guidelines present a series of recommendations based on evidence-based medicine, guidelines may also be a tool to unify the diagnostic and therapeutic approach in a vast medical field like phlebology. Since vascular surgeons and phlebologists are particularly involved in phlebology-related pathologies the scientific societies of the Italian Society of Phlebology (SIF) and the Italian Society for Vascular and Endovascular Surgery (SICVE) decided to cooperate for the preparation of phlebo-lymphological guidelines. These guidelines comprehend also an important chapter dealing with the lymphology of the lower extremities; phlebological active physicians are often faced with lymphatic pathologies and a good differential diagnosis can be sometimes very helpful. Sclerotherapy and Surgery as the major therapeutical alternatives are extensively analyzed, but also the compression therapy, the medical and physical therapy are presented under the critical view of evidence based analyses. Separate chapters deal with the treatment alternatives for superficial and deep venous thromboses and the recommendations for the treatment of venous ulcers. The current scientific evidences were confronted with the experiences of Italian specialists and the particular practice and reality in Italy. They represent therefore the actual valid positions and recommendations in Italy which shall be updated regularly.
