Incompetent perforators in leg


There is one VSDS score for reflux maximum score of 10 and another one for obstruction also a maxi- mum score of The Venous Clinical Severity Score VCSS is based on nine clinical characteristics pain, varicose veins, venous edema, skin pigmentation, inflammation, induration, and number, duration and size of active ulcersall graded from 0 to 3 and additionally use of conservative therapy compression and elevationusing the same points, to produce a 30 point-maximum flat scale.

It has been shown that the venous severity scores are significantly higher in advanced venous disease, demonstrating correlation with anatomic extent. VCSS has been found to be equally sensitive and significantly better for measuring changes in response to superficial venous incompetent perforators in leg than the CEAP clinical class, while VDS demonstrated comparable and even better performance.

It has been suggested that VCSS may have a more global application in determining the overall severity of venous disease. Additionally a clear association between VCSS and Incompetent perforators in leg findings has been demonstrated, suggesting that this score can be used as a screening tool.

Scoring systems for assessing the post-thrombotic syndrome PTS Three further different scoring systems have been proposed that are specific for the assessment of the PTS: the Brandjes Brandjes et althe Ginsburg Gins- burg and Villalta scales Villalta et al All three systems use symptoms and signs, which are present or absent in the Brandjes system but graded in the other two.

The Ginsberg system identifies the presence or absence of PTS without grading its severity. In contrast, the Villalta scale grades symptoms and signs and classifies patients into different PTS severity groups. Because of its reliability, high correlation with relevant health outcomes, acceptability, responsiveness to changes in the severity of PTS and successful use in clinical trials Kahn et al, the subcommittee on control of anticoagulation of the Scientific and Standardization Committee of the In- ternational Society on Thrombosis and Haemostasis recommended that the Villalta scale should be used in clinical studies to diagnose and grade the severity of PTS.

In a recent study assessing the Villalta, Ginsberg, Brandjes, Widmer, CEAP, and VCSS systems in terms of interobserver reliability, association with ambulatory venous cezariana în varicoza, ability to assess severity of post-thrombotic syndrome, ability to assess change in condition over time, and association with patient-reported symptom severity, only the Villalta score was able to fulfill all the above criteria, Soosainathan et al findings that endorse its generalized use in PTS.

Understanding the pathophysiology is the key to selecting the appropriate investigations. When a patient presents with symptoms and signs suggestive of CVD, a physician 25 Highlights from the document on the management of incompetent perforators in leg venous disorders of the în vene varicoase medicamentul din viena este introdus limbs should answer a number of clinically relevant questions.

First one should ascertain whether CVD is present. If it is, then investigations should determine the presence or absence of reflux, obstruction, calf muscle pump dysfunction and the severity of each Nicolaides, Detection of Reflux and Obstruction The clinical presentation is assessed with the history and physical examination followed by a duplex scan. Such an evaluation helps to identify the presence, sites and anatomical extent of reflux and potential occlusion of incompetent perforators in leg veins.

A proportion of patients may require additional investigations. Duplex Scanning Duplex ultrasound is superior to phlebography and is considered to be the gold standard to detect reflux in any venous segment.

The entire su- perficial and deep venous systems as well as the communicating incompetent perforators in leg perforating veins are examined. Elements of the examination that are often germane to further manage- ment include: 1. Standing position for the femoral and great saphenous veins or sitting position for popliteal, small saphenous and calf veins, 2.

Measurement of the duration, peak velocity or volume flow of reflux, after standard calf compression and its release 3. Size and competence of perforators, 4.

Diameter of saphenous veins, 5. Size and competence of major saphenous tributaries 6. Anatomic extent of reflux in the deep veins Obstruction Quantification of venous obstruction is difficult. Traditional methods that measure arm-foot pressure differential, outflow fraction and outflow resistance by plethysmography1 express global functional obstruction including the effect of the collateral circulation, but do not quantify local anatomic obstruction.

IVUS demonstrates relative degrees of obstruction at the involved venous segment more reliably, but it is not useful for infra-inguinal obstruction. A way to organize the diagnostic evaluation of the patient with CVD is to utilize one or more of three levels of testing, depending on the severity of the disease: Level I: The office visit with history and incompetent perforators in leg examination, which could inclu- de a pocket Doppler or color flow duplex.

Level II: The non-invasive vascular laboratory with detailed duplex scanning, with or without plethysmography. A simple guide to the level of incompetent perforators in leg in relation to CEAP clinical classes is 26 given below. This may be modified according to clinical circumstances and local prac- tice. Level I investigations are usually sufficient.

However, symptoms such as ache, pain, heaviness, leg-tiredness and muscle cramps in the absence of visible or palpable varicose veins are an indication for detailed duplex scanning to exclude reflux which often precedes the clinical manifestation of varices.

Clinical Class C2 Varicose veins present without any edema or skin changes.

Level II duplex scanning should be used in the majority of patients and is mandatory in those being considered for intervention. Level III may be needed in certain cases.

Clinical Class C3 Edema with or without varicose veins and without skin changes. Level II investigations are utilized to determine the severity of reflux and obstruction and whether or not reflux or obstruction in the deep veins is responsible for the edema. If obstruction is demonstrated or suspected as a result of duplex scanning, level III studies to investigate the deep venous system must be considered.

Whether or not obstruction is demonstrated, or suspected as a result of duplex scanning, level III studies to investigate the deep venous system may be considered.

Lymphoscintigraphy may be indicated to confirm the diagnosis of lymphedema in certain patients with suspected phlebolymphedema. Clinical Class C4,5,6 Skin changes suggestive of venous disease including healed or open ulceration with or without edema and varicose veins. Level II investigations will be required in virtually all patients.

Selected cases, such as those being considered for deep venous intervention, will proceed to incompetent perforators in leg III. Level I investigations may be sufficient in some patients with irreversible muscle pump dysfunction due to neurological disease, severe and non-correctable reduction of ankle movement or where there is a contraindication to surgical intervention.

Some investigations may have to be deferred, incompetent perforators in leg in patients with painful ulcers.

Due to edema reduction, bandages are losing pressure after application. Therefore bandages should initially be applied with high enough pressure and should be renewed when the pressure decreases into an ineffective range. They should be washable and reusable.

Multi-component bandages better meet the above requirements than single component bandages. Pads or rolls of different materials can be used to increase the local pressure over a treated venous segment following sclerotherapy or over a venous ulcer situated behind the medial malleolus. Incompetent perforators in leg should only be prescribed if riscul la vene varicoase are able to apply them on a regular basis.

They are best put on in the morning. New stockings should be prescribed after 3- 6 months if used daily. Different devices have been developed to facilitate application of stockings. Highlights from the document on the management of chronic venous disorders of the lower limbs While bandages are mainly used for the initial phases of compression therapy, stockings are recommended for maintenance and long term management in chronic conditions. Quality of Life and Compliance Compression treatment improves quality of life Charles and compliance is crucial to prevent ulcer recurrence Raju et al, Regular daily use of compression stockings for at least two years after DVT can reduce the incidence and severity of the post-thrombotic syndrome see below Several beneficial effects of compression treatment and methods used to measure these effects are summarized in Table 3.

Experimental studies have helped to understand the performance of incompetent perforators in leg compression devices on the normal and the diseased leg.

Table 3. The authors concluded that despite important methodological heterogeneity and sometimes sub-standard reporting the meta-analysis suggests that leg compression with 15mmHg is an effective treatment for CVD. Less pressure is ineffective and higher pressure may be of no additional benefit. The conclusion was incompetent perforators in leg there is insufficient, high quality evidence to determine whether or not compression stockings are effective as the sole and initial treatment of varicose veins or whether any type of stocking is superior to any other type.

Further studies are needed to determine the optimum type of compression in different CEAP classes of patients.

Effect of compression stockings in the prevention of PTS Four RCT investigated the efficacy of compression stockings in preventing the development of PTS in patients with proximal DVT who received conventional antico- agulant treatment. In the first study patients were randomized to compression stockings grade III or no stockings Branjes et al, The median follow-up was 76 months range in both groups.

In both groups, most cases of post-thrombotic syndrome occurred within 24 months of the acute thrombotic event. In the second study patients were randomised to wear or not wear below-knee compression elastic stockings grade Incompetent perforators in leg for 2 years Prandoni et al, Follow-up was performed for up to 5 years.

The third study assessed the effect of prolonged compression therapy after a stan- dard anticoagulant treatment for 6 months Aschwanden et al, At the end of anticoagulation patients were randomized to wear compression stockings grade II or not.

Primary efficacy analysis was performed on the end point of emerging skin changes C4-C6 according to the CEAP classification. The primary end point occurred in 11 Within subgroup analyses of the primary end point, we observed a large sex-specific difference between women HR, 0. The fourth study randomized one group of 47 patients to compression stockings grade II or placebo stockings and a second group of 35 patients to compression stockings incompetent perforators in leg III or placebo Ginsberg et al, Clear cut results have been obtained from the first two studies in which grade III stokings were used.

Thus the recommendation for grade III below knee stockings is grade A. In a recent RCT patients with the first episode of proximal deep venous thrombosis were randomized to wear either thigh-length or below-knee compression stockings for 2 years Prandoni et al, After 3, 6, 12, 18, 24, incompetent perforators in leg 36 months, they 29 Highlights from the document on the management of chronic venous disorders of the lower limbs were assessed for PTS manifestations according to the Villalta scale.

PTS developed in 44 Severe PTS developed in 3 patients in each group. Stocking-related side effects developed in 55 The authors concluded that thigh-length stockings do not offer a better protection against PTS than below-knee stockings and are less well tolerated. Effect of compression in the incompetent perforators in leg of venous ulcers There is a large number of publications on the efficacy of compression in healing venous leg ulcers.

The results are summarized by the Cochrane Database Systematic Review updated in Cullum et al, In this review, ulcer healing was the primary endpoint. When multi-layered systems were compared, elastic compression was more effective than non-elastic compression 5 trials.

There was no difference in healing rates between 4-layer bandaging and other high compression multi-layered systems 3 trials. There was no difference in healing rates between elastomeric multi-layered systems 4 trials.

Multi-layered high compression was varicele pot fi tratate cu lipitori effective than single layer compression 4 trials. The authors concluded that Compression increases ulcer healing rates compared with no compression. Multi-layered systems are more effective than single-layered systems. High compression is more effective than low compression.
