Possibilities and Prospects of Hemodynamic Surgery of Varicose Veins in the Era of Endovascular Thermal Obliteration

Долгое время единственным эффективным способом хирургического лечения варикозной болезни нижних конечностей считалось полное удаление ствола подкожной вены. Со временем помимо модификаций удаления вен с помощью зондов появились также эндовенозные термические методы облитерации, однако общим во всех этих методиках оставалось полное иссечение\облитерация несостоятельного сегмента ствола. Данная концепция начала претерпевать изменения только после появления и развития дуплексного ультразвукового сканирования сосудов, благодаря которому появилась возможность более глубокой оценки гемодинамики венозной системы и, как следствие, определения дальнейшего необходимого способа лечения отдельно взятого пациента. Именно благодаря подробному изучению венозной гемодинамики в 1988 г. французский ангиолог Клод Франчески предложил метод амбулаторной консервативной гемодинамической коррекции венозной недостаточности (Conservatrice et Hémodynamique de l’Insuffisance Veineuse en Ambulatoire), ставший известным в мире как метод CHIVA. Данный способ подразумевает устранение столба гидростатического давления в вене, устранение механизма рециркуляции крови, сохранение механизма re-entry и удаление притоков, не имеющих связи с точкой re-entry. В результате выполнения CHIVA происходит восстановление нормального физиологического тока крови путем устранения рефлюкса из глубокой вены в поверхностную и сохранения дренажа из поверхностных вен в глубокие. В представленном обзоре подробно рассматриваются достоинства и недостатки метода CHIVA, а также проведен сравнительный анализ методики с другими существующими на данный момент способами лечения варикозной болезни.

Tumescent anaesthesia in combination with femoral nerve block for surgery of varicose veins: prilocaine 0.1% versus 0.2%

Objective Results of a prospective, randomized, double-blinded study about tumescent anaesthesia (TA) in combination with femoral nerve block (FNB) for surgery of varicose veins are reported. The aim is to compare two different concentrations of prilocaine in TA. Method With approval of the ethical committee and informed consent, FNB (nerve stimulation, 20 mL prilocaine 0.75%) was performed followed by TA using prilocaine 0.1% versus 0.2% (groups P0.1 and P0.2). Further medication was standardized. Overall amount of prilocaine was recorded, plasma levels of 20 patients measured regularly. Side-effects, patient satisfaction and pain scores were compared ( P < 0.05). Results Ninety patients were included. In one patient (P0.1), general anaesthesia was necessary. There was no difference in pain scores, need for rescue medication or patient satisfaction. More prilocaine was administered in P0.2 ( P < 0.0001) with higher but far below toxic plasma levels. In three patients (P0.2) mild met-haemoglobinaemia was confirmed. Conclusion TA with prilocaine 0.1% in combination with FNB is sufficient to provide high patient satisfaction during varicosis surgery.

Surgical treatment of varicose vein using the tumescent technique of local anesthesia

Background/Aim. Tumescent local anesthesia (TLA) is a technique for local and regional anesthesia of the skin and the subcutaneous tissue, using infiltration of large amounts of a diluted solution of local anesthetic. This technique is applied in plastic surgery, liposuction as well as in dermatology for the entire series of dermatocosmetic procedures. The purpose of this study was to determine efficiency of surgical treatment of varicose vein using TLA as an alternative method to a conventional treatment for varicose vein. Methods. Seventy-two patients with varicose vein were enrolled in the study. All of them were operated on applying TLA, from April 2008 to November 2009. TLA solution consisted of local anesthetics was used. TLA solutions used were: 1% prilocaine-chloride with adrenaline supplement, and 2% lidocaine-chloride and adrenaline in concentration of 0.1%-0.4%. Results. Out of 72 patients, we stripped great saphenous vein from 60 patient and did varicectomy as well as ligation of insufficiently perforating veins. In 12 patients we did partial varicectomy and ligation of perforating veins. There were not any patients with the need for continued surgery, as well as bringing patient to the general anesthesia due to pain during the surgery. One patient came for postoperative opening wound in the groin, one for infection of the wound and one for the formation of seroma in the groin. There were not any allergic reactions or systemic complications in the operations as well as postoperative period. Postoperatively, all the patients were treated with compressive elastic bandage during the period of 6 weeks as well as anticoagulation prophylaxis in the duration of 5 days. Conclusion. Surgery of varicose veins with implementation of TLA is easy and safe method with very low percentage of complications and unwanted effects. It is a good alternative method to classic surgery of varicose veins. The economic aspect is a very important component because the cost of this method is significantly lower than that of a classical surgical treatment of varicose veins.

Tumescent anaesthesia in combination with a femoral nerve block or a sciatic nerve block for surgery of varicose veins

SummaryTumescent anaesthesia is a widley accepted anaesthetic procedure for the surgery of varicous veins. In our institution tumescent anaesthesia is regularly combined with femoral nerve block or sciatic nerve block for primary operations of the great saphenous vein (GSV) or small saphenous vein (SSV).This combined procedure is described. Retrospective data of 154 operations of the GSV and of 27 operations of the SSV are presented. We used 9.5 mg/kg body weight of prilocain for operations of the GSV and 8.6 mg/kg body weight for operations of the SSV. No serious complications occurred.

Surgery of varicose veins with transilluminated powered mini-phlebectomy: clinical experience

The authors report their experience with a new surgical technique, the transilluminated powered mini-phlebectomy (Trivex' System, Smith & Nephew Inc, Andover, USA), to remove primary varicose veins. There were 70 patients, 50 women and 20 men, with a mean age of 52 ± 9 years. The average operating time was 56 ± 8 min (range 30–75 min). The mean number of incisions was five (range 2–8). The postoperative pain, cosmetic scores and all complications were evaluated prospectively.
