[Interventional treatment of venous insufficiency]. / Prise en charge interventionnelle de l'insuffisance veineuse superficielle des membres inférieurs.

Interventional treatment of venous insufficiency has been revolutionized by endovascular techniques. Some of these techniques, and particularly thermal ablation (endovenous laser, radiofrequency) are now recommended as first-line therapy in the latest international guidelines. This is because of less post-operative pain, a shorter leave from employment and similar or lower recurrence rate. Endovenous techniques allow safer and more efficient treatment of certain particular conditions : small saphenous vein, ulcers, and recurrent varicose veins. In addition to clinical history and examination, a duplex sonography of deep and superficial veins, performed by an angiologist, is the most important exam in order to determine proper indication and best treatment strategy for each patient.

La prise en charge de l'insuffisance veineuse des membres inférieurs a été révolutionnée par l'avènement des techniques endoveineuses. En particulier, l'ablation thermique par laser endoveineux, ou radiofréquence des troncs saphéniens, a remplacé la chirurgie comme technique de référence dans les dernières guidelines publiées, notamment en raison d'une diminution des douleurs postinterventionnelles et de la durée d'incapacité de travail avec un taux de récidives identique, voire inférieur. Les techniques endoveineuses permettent, en outre, de traiter certaines indications avec un niveau d'efficacité et de sécurité accru : traitement de la petite veine saphène, ulcères et récidives de varices. Afin de déterminer l'indication et la meilleure stratégie de prise en charge, un bilan veineux par écho-Doppler par un angiologue est une étape obligatoire.

Sclerotherapy of telangiectasias: a painless two-step technique.

BACKGROUND: Sclerotherapy of telangiectasias and reticular leg veins can be unpleasant and painful for some patients. OBJECTIVE: To determine pain level with two different sclerotherapy techniques in a prospective randomized trial. METHODS: Patients with symmetrical telangiectasias and reticular veins on both legs (C(1A) or (S)E(P)A(S)P(N1) were randomized to the standard (successive injections of chromated glycerin mixed with one-third lidocaine-epinephrine 1%) or two-step technique (first treating only reticular veins with a single injection at the base of each cluster of telangiectasias and then successively injecting all remaining telangiectasias a few minutes later. Pain was assessed using a 100-point visual analogue scale (0 = no pain, 100 = maximum pain). RESULTS: Data from 53 consecutive patients could be evaluated. The two-step technique was significantly less painful (28.2) than the standard technique (40.6, p < .001). CONCLUSION: The two-step technique with chromated glycerin mixed with one-third lidocaine-epinephrine 1% significantly reduces sclerotherapy pain. This may be a useful technique for patients who are particularly sensitive or afraid of sclerotherapy.

A double-blind, randomized study comparing pure chromated glycerin with chromated glycerin with 1% lidocaine and epinephrine for sclerotherapy of telangiectasias and reticular veins.

BACKGROUND: Chromated glycerin (CG) is an effective, although painful, sclerosing agent for telangiectasias and reticular leg veins treatment. OBJECTIVE: To determine pain level and relative efficacy of pure or one-third lidocaine-epinephrine 1% mixed chromated glycerin in a prospective randomized double-blind trial. METHOD: Patients presenting with telangiectasias and reticular leg veins on the lateral aspect of the thigh (C(1A) or (S) E(P) A(S) P(N1) ) were randomized to receive pure CG or CG mixed with one-third lidocaine-epinephrine 1% (CGX) treatment. Lower limb photographs were taken before and after treatment and analyzed by blinded expert reviewers for efficacy assessment (visual vein disappearance). Patients' pain and satisfaction were assessed using visual analogue scales. RESULTS: Data from 102 of 110 randomized patients could be evaluated. Patient pain scores were significantly higher when pure CG was used than with CGX (p<.001). Patient satisfaction with treatment outcome was similar in the two groups. Objective visual assessment of vessel disappearance revealed no significant difference between the two agents (p=.07). CONCLUSION: Addition of lidocaine-epinephrine 1% to CG, in a ratio of one-third, significantly reduces sclerotherapy pain without affecting efficacy when treating telangiectasias and reticular leg veins.

Compression after sclerotherapy for telangiectasias and reticular leg veins: a randomized controlled study.

BACKGROUND: The efficacy of wearing compression stockings on clinical vessel disappearance following sclerotherapy of telangiectasias and reticular veins has been a matter of debate for half a century. OBJECTIVE: To determine the relative efficacy of compression following sclerotherapy and to determine its impact on general quality of life in a prospective randomized open-label trial. METHODS: Female patients seeking treatment of telangiectasias and reticular veins and presenting comparable areas of telangiectasias on the lateral aspect of the thigh (C1AorSEPAS1PN) were randomized to wear medical compression stockings (23 to 32 mm Hg) daily for 3 weeks or no such treatment following a single session of standardized liquid sclerotherapy. Outcome was assessed by patient satisfaction analysis and quantitative evaluation of photographs taken from the lateral aspect of the thigh before and again at 52 days on the average after sclerotherapy by two blinded expert reviewers. Patients completed a quality of life questionnaire (SF-36) before treatment and again at the control. RESULTS: Data of 96 of 100 randomized patients could be evaluated. Patient satisfaction with the outcome of treatment was similar in the two groups. Objective assessment of clinical vessel disappearance revealed a benefit of wearing stockings (P=.026) corresponding to a NNT (number needed to treat) of 4.7 patients to get a vessel disappearance score higher than 6. The interobserver agreement was very high (intraclass correlation coefficient=0.93). Compression was well tolerated with a low rate of discomfort claims (mean 17.5%). Micro-thrombi were rarely observed in either group, but still less prevalent in the compression group. The rate of pigmentation and matting was low and did not differ significantly between the two groups. Physical and mental quality of life scores in women seeking treatment of telangiectasias were similar to those of a healthy control population. Treatment had no impact on general quality of life. CONCLUSION: Wearing compression stockings (23 to 32 mm Hg) for 3 weeks enhance the efficacy of sclerotherapy of leg telangiectasias by improving clinical vessel disappearance.

[Superficial thrombophlebitis]. / Thrombophlébite superficielle.

Superficial thrombophlebitis is a frequent complication of varicose veins that occurs rarely on normal veins. In the latter case, it may be associated with thrombophilia, cancer or inflammatory disease. Superficial thrombophlebitis is rarely complicated by deep vein thrombosis through extension in the deep vein system. Therefore, depending of its localisation, a venous ultrasound is indicated to evaluate its extension. Treatment is based on elastic compression, non steroid anti-inflammatory drugs and mobilisation. If thrombophlebitis approaches the saphenous junction with the deep vein systems or involves perforans veins anticoagulant treatment is indicated.

Single-blind, randomized study comparing chromated glycerin, polidocanol solution, and polidocanol foam for treatment of telangiectatic leg veins.

BACKGROUND: A single-blind, randomized, comparative study was performed to evaluate the efficacy of pure chromated glycerin (CG), polidocanol (POL) 0.25% solution, and POL 0.25% foam (Monfreux technique) for treatment of telangiectasias and reticular leg veins. OBJECTIVE: To determine the relative efficacy and safety of two sclerosing agents and foam. METHOD: Of 150 randomized patients presenting comparable areas (lateral face of thigh) of telangiectasias and reticular leg veins, 147 could be evaluated by photographic assessment, patients' satisfaction score, and pain at injection sites. Internal and external agreement for the photographic assessment was good for two independent blinded experts. RESULTS: CG cleared vessels significantly better than POL solution or foam (p<0.002). The patients' satisfaction score was also higher in the CG group, although the difference did not reach statistical significance. CG was significantly more painful at injection sites. Other side effects were very few, precluding any statistical comparison. Foam was associated with more side effects (microthrombi, matting) than CG or POL solution. Three patients treated with POL foam experienced a transient visual disturbance. CONCLUSION: This study shows that CG is superior to POL solution and foam for sclerotherapy of leg telangiectasias.
