Sclerotherapy of Vascular Malformations in the Oral Cavity-Minimizing Postoperative Morbidity.

Vascular malformations (VMs) are a wide vascular or lymphatic group of lesions common on the head and neck. The objective of this study was to assess the efficacy and morbidity of sclerotherapy for the treatment of VMs in the oral and perioral area. Special attention was given to factors that may contribute to minimizing postoperative morbidity. Data from 25 patients (32 lesions) with oral VMs submitted to sclerotherapy with monoethanolamine oleate (EAO) were included. A structured form was used to collect data. An arbitrary score was determined to evaluate postoperative morbidity. Each of the following signs or symptoms received one point: pain, swelling, hematoma, ulceration, erythema, transient numbness, and transient itching. Pain and swelling were further divided into mild to moderate (1 point) and severe (2 points). Theoretically, the score was in the range of 0-9. Calculated scores ranged 0-4. The patients were further divided into two groups with scores of 0-1 denoting minimal morbidity (MIN) and 2-4 denoting significant morbidity (SIG). The number of lesions in each morbidity-score group were comparable (MIN 17and SIG 15). There were no statistically significant differences between the groups regarding age, number of applications, or average injection volume per mm lesion. Statistically significant differences were noted regarding gender (p = 0.05), lesion diameter (p = 0.030), total volume of first (p = 0.007) and second application (p = 0.05), and total injected volume (p = 0.03). Factors contributing to the risk for significant morbidity included being male, lesion diameter > 5 mm, volume > 0.3 mL per application, and total injected volume > 0.3 mL. A waiting time of 12 weeks prior to additional EAO application was required in 12 out of 29 lesions for clinical observation of complete regression. It was concluded that sclerotherapy with EAO as monotherapy is easy to apply, safe, and effective within a small number of sessions. Application of <0.3 mL EAO per session, and a waiting time of 12 weeks prior to the second application, would significantly minimize morbidity.

Patient radiation doses and reference levels in pediatric interventional radiology.

OBJECTIVES: To describe, in a multicentric paediatric population, reference levels (RLs) for three interventional radiological procedures. METHODS: From January 2012 to March 2015, children scheduled for an interventional radiological procedure in two French tertiary centres were retrospectively included and divided into four groups according to age: children younger than 2 years (A1), aged 2-7 years (A5), 8-12 years (A10) and 13-18 years (A15). Three procedures were identified: cerebral digital subtraction angiography (DSA), brain arteriovenous malformation (bAVM) embolization, and head and neck superficial vascular malformation (SVM) percutaneous sclerotherapy. Demographic and dosimetric data, including dose area product (DAP), were collected. RESULTS: 550 procedures were included. For DSA (162 procedures), the proposed RL values in DAP were 4, 18, 12 and 32 Gy∙cm2 in groups A1, A5, A10 and A15, respectively. For bAVM embolization (258 procedures), values were 33, 70, 105 and 88 Gy∙cm2 in groups A1, A5, A10 and A15, respectively. For SVM sclerotherapy (130 procedures), values were 350, 790, 490 and 248 mGy∙cm2 in groups A1, A5, A10 and A15, respectively. CONCLUSION: Consecutive data were available to permit a proposal of reference levels for three major paediatric interventional radiology procedures. KEY POINTS: • We determined reference levels (RLs) for bAVM embolization, DSA and SVM sclerotherapy. • The proposed RLs will permit benchmarking practice with an external standard. • The proposed RLs by age may help to develop paediatric dose guidelines.

A synopsis of current international guidelines and new modalities for the treatment of varicose veins.

BACKGROUND: The UK National Institute for Health and Care Excellence released new guidelines in 2013 recommending that endovenous thermal ablation (laser or radiofrequency) and ultrasound-guided foam sclerotherapy should be offered before conventional surgery for treat-ment of varicose veins and saphenous vein reflux. OBJECTIVE: The aim of this article is to provide a synopsis of current international guidelines and recent advances for the treatment of varicose veins. DISCUSSION: Conventional surgery involving classical high ligation and stripping of the saphenous vein has been standard practice for nearly a century. Surgery requires general anaesthesia and hospitalisation, and there is a high rate of recurrent disease. In the past decade there has been an international trend where the minimally invasive techniques of endovenous thermal ablation and ultrasound-guided foam sclerotherapy, which do not require hospitalisation, are beginning to displace surgery. These changes in technique have been supported by recently published international guidelines.

The risk of bacteria in foam sclerotherapy: does the condition of the air in outpatient vs. operating rooms make a difference?

BACKGROUND: Foam sclerotherapy has been one of the most frequently applied therapeutic methods for the treatment of varicose veins and venous malformation. Few studies have investigated the sterile condition of the air used for foam creation. OBJECTIVES: To evaluate the bacterial conditions in foam created from the air in outpatient and operating rooms used for sclerotherapy treatment, in order to provide the basis for clinical applications in foam sclerotherapy. MATERIALS AND METHODS: In this study, we measured the amount of airborne microorganisms in the air in the operating room, and in the outpatient room, the polidocanol (POL) foam created using the air in the respective rooms, and the microorganisms present in the liquid POL. We used the settle plate method for air sampling. We used the Tessari method to generate foam. The experiment was repeated three times. RESULTS: Typical bacterial colonies were formed on nutrient agar plates in both the outpatient room and operating room air groups. No colonies were cultivated in the liquid POL. Although the use of sterile or nonsterile air in sclerotherapy produces significantly different results in the counts of colony-forming units, there was no difference in the foam created using sterile or nonsterile air (i.e. no colonies were cultivated on either foam). CONCLUSIONS: There is no increased risk of infection when using foam sclerotherapy in outpatient rooms compared with using foam created under sterile operating-room conditions.

Consensus for sclerotherapy.

BACKGROUND: The American Society for Dermatologic Surgery (ASDS) periodically develops consensus documents for its members concerning various aspects of dermatologic surgery. Unwanted and painful leg veins are a very widespread problem. Many advances in sclerotherapy of varicose and telangiectatic leg veins have occurred since the previous consensus documents. OBJECTIVE: In 2013, the ASDS Board of Directors voted to have a committee of experts in the field to develop consensus documents on sclerotherapy. MATERIALS AND METHODS: An expert panel reviewed the literature on sclerotherapy and discussed the findings. A consensus was reached with evidence-based recommendations on diagnostic evaluation and treatment of varicose and telangiectatic leg veins. RESULTS: The consensus documents include discussion of indications for treatment, patient selection, contraindications, diagnostic testing, treatment approaches, use of compression, and expected outcome. Common sclerosants and their mechanisms of action, advantages and disadvantages of foam sclerotherapy, and minimizing and treating complications are presented. CONCLUSION: The ASDS consensus documents on sclerotherapy will be helpful in educating their members on safe and effective sclerotherapy of varicose and telangiectatic leg veins.

[European guidelines for sclerotherapy in chronic venous disorders]. / Europske smjernice za skleroterapiju kod kronicnih venskih poremecaja.

AIM: Sclerotherapy is the targeted chemical ablation of varicose veins by intravenous injection of a liquid of foamed sclerosing drug. The treated veins may be intradermal, subcutaneous, and/or transfascial as well as superficial and deep in venous malformations. The aim of this guideline is to give evidence-based recommendations for liquid and foam sclerotherapy. METHODS: This guideline was drafted on behalf of 23 European Phlebological Societies during Guideline Conference on 7-10 May 2012 in Mainz. The conference was organized by the German Society of Phlebology. These guidelines review the present state of knowledge as reflected in published medical literature. The regulatory situation of sclerosant drugs differs from country to country but this has not been considered in this document. The recommendations of this guiedeline are graded according to the American College of Chest Physicians Task Force recommendations on Grading Strenght of Recommendations and Quality of Evidence in Clinical Guidelines. RESULTS: This guideline focuses on the two sclerosing drugs which are licensed in the majority of the European countries, polidokanol and sodium tetradecyl sulphate. Other sclerosants are dot discussed in detail. The guideline gives recommendations concerning indications, contraindications, side-effects, concentrations, volumes, technique and efficacy of liquid and foam sclerotherapy of varicose veins and venous malformations.

The care of patients with varicose veins and associated chronic venous diseases: clinical practice guidelines of the Society for Vascular Surgery and the American Venous Forum.

The Society for Vascular Surgery (SVS) and the American Venous Forum (AVF) have developed clinical practice guidelines for the care of patients with varicose veins of the lower limbs and pelvis. The document also includes recommendations on the management of superficial and perforating vein incompetence in patients with associated, more advanced chronic venous diseases (CVDs), including edema, skin changes, or venous ulcers. Recommendations of the Venous Guideline Committee are based on the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) system as strong (GRADE 1) if the benefits clearly outweigh the risks, burden, and costs. The suggestions are weak (GRADE 2) if the benefits are closely balanced with risks and burden. The level of available evidence to support the evaluation or treatment can be of high (A), medium (B), or low or very low (C) quality. The key recommendations of these guidelines are: We recommend that in patients with varicose veins or more severe CVD, a complete history and detailed physical examination are complemented by duplex ultrasound scanning of the deep and superficial veins (GRADE 1A). We recommend that the CEAP classification is used for patients with CVD (GRADE 1A) and that the revised Venous Clinical Severity Score is used to assess treatment outcome (GRADE 1B). We suggest compression therapy for patients with symptomatic varicose veins (GRADE 2C) but recommend against compression therapy as the primary treatment if the patient is a candidate for saphenous vein ablation (GRADE 1B). We recommend compression therapy as the primary treatment to aid healing of venous ulceration (GRADE 1B). To decrease the recurrence of venous ulcers, we recommend ablation of the incompetent superficial veins in addition to compression therapy (GRADE 1A). For treatment of the incompetent great saphenous vein (GSV), we recommend endovenous thermal ablation (radiofrequency or laser) rather than high ligation and inversion stripping of the saphenous vein to the level of the knee (GRADE 1B). We recommend phlebectomy or sclerotherapy to treat varicose tributaries (GRADE 1B) and suggest foam sclerotherapy as an option for the treatment of the incompetent saphenous vein (GRADE 2C). We recommend against selective treatment of perforating vein incompetence in patients with simple varicose veins (CEAP class C(2); GRADE 1B), but we suggest treatment of pathologic perforating veins (outward flow duration ≥500 ms, vein diameter ≥3.5 mm) located underneath healed or active ulcers (CEAP class C(5)-C(6); GRADE 2B). We suggest treatment of pelvic congestion syndrome and pelvic varices with coil embolization, plugs, or transcatheter sclerotherapy, used alone or together (GRADE 2B).

Foam sclerotherapy using polidocanol for balloon-occluded retrograde transvenous obliteration (BRTO).

PURPOSE: To evaluate the clinical safety and effectiveness of foam sclerotherapy using polidocanol for the treatment of gastric fundal varices by balloon-occluded retrograde transvenous obliteration (BRTO). MATERIALS AND METHODS: From November 2005 to June 2009, foam sclerotherapy using polidocanol for the treatment of gastric fundal varices by BRTO was performed in 16 patients (male/female 11:5; age range 46-84 years, median 67 years). Foam was made of 3% polidocanol (Aethoxysklerol; Kreussler Pharma, Wiesbaden, Germany), room air, and contrast media, with a ratio of 1:2:1, respectively. The amount of polidocanol (2-24 mL; median 7 mL) depended on the volume of varices. RESULTS: Technical success was achieved in 15 of 16 patients (93.8%). Technical failure occurred in one patient. All patients were without pain during sclerotherapy. One patient experienced pulmonary edema after the procedure but completely recovered with medical treatment. There was no procedure-related mortality. Patients were followed by endoscopy, computed tomography, or both. Four patients were lost to follow-up. Clinical success was achieved in 10 of 11 patients (91%). Rebleeding occurred in one case during follow-up. CONCLUSIONS: Foam sclerotherapy using polidocanol is clinically safe and effective for the treatment of gastric fundal varices during BRTO.

[Sclerotherapy of a simple, solitary kidney cyst using intraluminal ethanol instillation in a Swiss Fleckvieh cow]. / Sklerotherapie einer einfachen, solitären Nierenzyste mittels intraluminaler Ethanolinstillation bei einer Swiss Fleckvieh-Kuh.

INTRODUCTION: Renal cysts are fluid-filled cavities with an epithelial lining that, depending on their size, can cause clinical symptoms and thus require conservative or surgical therapy. Nephrectomy is primarily used in cattle for simple kidney cysts while sclerotherapy is well established in humans and individual case reports have been published in small animal medicine. This case report describes the first successful treatment of a solitary, perirenal cyst using a right-sided laparotomy and intraluminal instillation of 96% ethanol solution in a Swiss Fleckvieh cow. Diagnostics, surgical procedures and aftercare are descripted and risks are compared to other methods. Sclerotherapy is an organ-preserving alternative to nephrectomy that is suitable for buiatric practice, the methodology should be confirmed in subsequent intervention studies.

INTRODUCTION: Les kystes rénaux sont des cavités remplies de liquide avec une muqueuse épithéliale qui, en fonction de leur taille, peuvent provoquer des symptômes cliniques et nécessitent donc un traitement conservateur ou chirurgical. Alors que la sclérothérapie pour le traitement des kystes rénaux simples est bien établie chez l'homme et que des rapports de cas individuels ont également été décrits en médecine des petits animaux, la néphrectomie est principalement utilisée chez les bovins. Ce rapport de cas décrit pour la première fois le traitement réussi d'un kyste périrénal solitaire par instillation intraluminale d'une solution d'éthanol à 96% après une laparotomie droite chez une vache de race Swiss Fleckvieh. Les aspects du diagnostic, des procédures chirurgicales et des soins de suivi sont expliqués et les risques par rapport aux autres méthodes sont discutés. La sclérothérapie est une alternative de préservation des organes à la néphrectomie qui convient à la pratique buiatrique et dont la méthodologie doit être confirmée dans des études d'interventions ultérieures.

The recommended goal in the United Kingdom's National Institute for Health and Care Excellence Clinical Guideline 168 for immediate referral of patients with bleeding varicose veins is not being achieved.

OBJECTIVE: Published in July 2013, National Institute for Health and Care Excellence Clinical Guideline 168 (CG168) recommended that people with bleeding varicose veins be referred immediately to a vascular service. We have examined the impact of CG168 on referral practice for patients with bleeding varicose veins from primary to secondary care in a local National Health Service setting. METHODS: Referrals to a local vascular service in the 6 years before (group 1) and 6 years after (group 2) publication of CG168 were analyzed to assess patients' management after a bleed, with particular reference to a patient's initial presentation and delays in referral to the vascular service. This was done by retrospective electronic database and case note interrogation of patients presenting with bleeding varicose veins. Relevant data were collected onto an Excel spread sheet (Microsoft, Redmond, Wash) in relation to demographic information, comorbidities, clinical presentation, and treatment pathway. RESULTS: During the period studied, 73 patients presented with bleeding varicose veins. Their mean age was 66 years, and 56% were men. Their mean body mass index was 28 kg/m2. Of note, 33 patients (45%) initially self-treated before going to see their general practitioner; another 18 (25%) went to the emergency department. In 51 patients (70%), the underlying superficial disease involved the great saphenous vein, and most patients (73%) were treated with foam sclerotherapy with or without truncal thermal ablation; 45 patients (group 1) were treated in the 6 years before publication of CG168, and 28 patients, allowing 6 months for dissemination, were treated in the 6 years after CG168 publication (group 2). Mean time from index bleed to referral to the vascular service was faster after publication of CG168 (84 days before and 20 days after publication of CG168; P = .00842). Publication of CG168 was also associated with reduced mean bleed to intervention times (194 vs 60 days; P = .00097). CONCLUSIONS: Publication of UK National Institute for Health and Care Excellence guideline CG168 has been associated with a significant reduction in the delay to referral of patients presenting with bleeding varicose veins; however, the goal of immediate referral to a vascular service is not being met. CG168 is likely to have been a significant component of the factors that have led to the improvements seen thus far.

Sclerotherapy of varicose veins with polidocanol based on the guidelines of the German Society of Phlebology.

BACKGROUND: Sclerotherapy involves the injection of a sclerosing agent for the elimination of intracutaneous, subcutaneous, and transfascial varicose veins. OBJECTIVE: To update guidelines for sclerotherapy of varicose veins. METHODS: The guidelines for sclerotherapy of varicose veins of the German Society of Phlebology were updated and modified through a review of the available literature. RESULTS: Published clinical series and controlled clinical trials provide evidence to support the elimination of intracutaneous and subcutaneous varicose veins using sclerotherapy. Allergic skin reactions occur occasionally as allergic dermatitis, contact urticaria, or erythema. Anaphylaxis is rare. Transient migraine headaches present more frequently in patients treated with foam sclerotherapy than liquid sclerotherapy. CONCLUSION: Sclerotherapy is the method of choice for the treatment of small-caliber varicose veins (reticular varicose veins, spider veins). If performed properly, sclerotherapy is an efficient treatment method with a low incidence of complications.

Compression therapy after invasive treatment of superficial veins of the lower extremities: Clinical practice guidelines of the American Venous Forum, Society for Vascular Surgery, American College of Phlebology, Society for Vascular Medicine, and International Union of Phlebology.

Guideline 1.1: Compression after thermal ablation or stripping of the saphenous veins. When possible, we suggest compression (elastic stockings or wraps) should be used after surgical or thermal procedures to eliminate varicose veins. [GRADE - 2; LEVEL OF EVIDENCE - C] Guideline 1.2: Dose of compression after thermal ablation or stripping of the varicose veins. If compression dressings are to be used postprocedurally in patients undergoing ablation or surgical procedures on the saphenous veins, those providing pressures >20 mm Hg together with eccentric pads placed directly over the vein ablated or operated on provide the greatest reduction in postoperative pain.[GRADE - 2; LEVEL OF EVIDENCE - B] Guideline 2.1: Duration of compression therapy after thermal ablation or stripping of the saphenous veins. In the absence of convincing evidence, we recommend best clinical judgment to determine the duration of compression therapy after treatment. [BEST PRACTICE] Guideline 3.1: Compression therapy after sclerotherapy. We suggest compression therapy immediately after treatment of superficial veins with sclerotherapy to improve outcomes of sclerotherapy. [GRADE - 2; LEVEL OF EVIDENCE - C] Guideline 3.2: Duration of compression therapy after sclerotherapy. In the absence of convincing evidence, we recommend best clinical judgment to determine the duration of compression therapy after sclerotherapy. [BEST PRACTICE] Guideline 4.1: Compression after superficial vein treatment in patients with a venous leg ulcer. In a patient with a venous leg ulcer, we recommend compression therapy over no compression therapy to increase venous leg ulcer healing rate and to decrease the risk of ulcer recurrence. [GRADE - 1; LEVEL OF EVIDENCE - B] Guideline 4.2: Compression after superficial vein treatment in patients with a mixed arterial and venous leg ulcer. In a patient with a venous leg ulcer and underlying arterial disease, we suggest limiting the use of compression to patients with ankle-brachial index exceeding 0.5 or if absolute ankle pressure is >60 mm Hg. [GRADE - 2; LEVEL OF EVIDENCE - C].

Cryoablation of low-flow vascular malformations.

PURPOSE: We aimed to evaluate the safety and effectiveness of cryoablation in the treatment of low-flow malformations, specifically venous malformation (VM) and fibroadipose vascular anomaly (FAVA). METHODS: We conducted a retrospective review of 11 consecutive patients with low-flow malformations (14 lesions; 9 VM, 5 FAVA), median lesion volume 10.8 cm3, (range, 1.8-55.6 cm3) with a median age of 19 years (range, 10-50 years) who underwent cryoablation to achieve symptomatic control. Average follow-up was at a median of 207 days postprocedure (range, 120-886 days). Indications for treatment included focal pain and swelling. Technical success was achieved if the cryoablation ice ball covered the region of the malformation that corresponded to the patient's symptoms. Clinical success was considered complete if all symptoms resolved and partial if some symptoms persisted but did not necessitate further treatment. RESULTS: The technical success rate was 100%. At 1-month follow-up, 13 of 14 lesions (93%) had a complete response and one (7%) had a partial response. At 6-month follow-up 12 of 13 (92%) had a complete response and 1 (8%) had a partial response. A total of 6 patients underwent primary cryoablation. Out of 9 VM cases, 7 had prior sclerotherapy and 2 had primary cryoablation. Out of the 5 FAVA cases, 1 had prior sclerotherapy and the remaining 4 cases underwent primary cryoablation. There were 3 minor complications following cryoablation including 2 cases of skin blisters and 1 case of transient numbness. These complications resolved with conservative management. CONCLUSION: Cryoablation is safe and effective in the treatment of low-flow vascular malformations, either after sclerotherapy or as primary treatment.

[Linee guida flebo-linfologiche SIF-SICVE 2016 della Società Italiana di Flebologia e della Società Italiana di Chirurgia Vascolare ed Endovascolare].

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.

Diagnosis and Treatment of Venous Malformations. Consensus Document of the International Union of Phlebology (IUP): updated 2013.

Venous malformations (VMs) are the most common vascular developmental anomalies (birth defects) . These defects are caused by developmental arrest of the venous system during various stages of embryogenesis. VMs remain a difficult diagnostic and therapeutic challenge due to the wide range of clinical presentations, unpredictable clinical course, erratic response to the treatment with high recurrence/ persistence rates, high morbidity following non-specific conventional treatment, and confusing terminology. The Consensus Panel reviewed the recent scientific literature up to the year 2013 to update a previous IUP Consensus (2009) on the same subject. ISSVA Classification with special merits for the differentiation between the congenital vascular malformation (CVM) and vascular tumors was reinforced with an additional review on syndrome-based classification. A "modified" Hamburg classification was adopted to emphasize the importance of extratruncular vs. truncular sub-types of VMs. This incorporated the embryological ongm, morphological differences, unique characteristics, prognosis and recurrence rates of VMs based on this embryological classification. The definition and classification of VMs were strengthened with the addition of angiographic data that determines the hemodynamic characteristics, the anatomical pattern of draining veins and hence the risk of complication following sclerotherapy. The hemolymphatic malformations, a combined condition incorporating LMs and other CVMs, were illustrated as a separate topic to differentiate from isolated VMs and to rectify the existing confusion with name-based eponyms such as Klippei-Trenaunay syndrome. Contemporary concepts on VMs were updated with new data including genetic findings linked to the etiology of CVMs and chronic cerebrospinal venous insufficiency. Besides, newly established information on coagulopathy including the role of D-Dimer was thoroughly reviewed to provide guidelines on investigations and anticoagulation therapy in the management of VMs. Congenital vascular bone syndrome resulting in angio-osteo-hyper/hypotrophy and (lateral) marginal vein was separately reviewed. Background data on arterio-venous malformations was included to differentiate this anomaly from syndromebased VMs. For the treatment, a new section on laser therapy and also a practical guideline for follow up assessment were added to strengthen the management principle of the multidisciplinary approach. All other therapeutic modalities were thoroughly updated to accommodate a changing concept through the years.

Towards measurement of outcome for patients with varicose veins.

OBJECTIVE: To develop a valid and reliable outcome measure for patients with varicose veins. DESIGN: Postal questionnaire survey of patients with varicose veins. SETTING: Surgical outpatient departments and training general practices in Grampian region. SUBJECTS: 373 patients, 287 of whom had just been referred to hospital for their varicose veins and 86 who had just consulted a general practitioner for this condition and, for comparison, a random sample of 900 members of the general population. MAIN MEASURES: Content validity, internal consistency, and criterion validity. RESULTS: 281(76%) patients (mean age 45.8; 76% female) and 542(60%) of the general population (mean age 47.9; 54% female) responded. The questionnaire had good internal consistency as measured by item-total correlations. Factor analysis identified four important health factors: pain and dysfunction, cosmetic appearance, extent of varicosity and complications. The validity of the questionnaire was demonstrated by a high correlation with the SF-36 health profile, which is a general measure of patients' health. The perceived health of patients with varicose veins, as measured by the SF-36, was significantly lower than that of the sample of the general population adjusted for age and a lower proportion of women. CONCLUSION: A clinically derived questionnaire can provide a valid and reliable tool to assess the perceived health of patients with varicose veins. IMPLICATIONS: The questionnaire may be used to justify surgical treatment of varicose veins.

Aspiration and tetracycline sclerotherapy: a novel method for management of vaginal and vulval Gartner cysts.

Fifteen patients suffering from symptomatic Gartner cysts were subjected to cyst fluid aspiration and 5% tetracycline injection of a similar volume (as that of aspirated cyst fluid) under local analgesia. Twenty-four hours later the injected tetracycline was re-aspirated until the cyst walls collapsed. The procedure was easy, inexpensive, acceptable by all patients with no operative or postoperative complaints or complications and no cyst reformation. This novel technique is an ideal, safe and effective simple office procedure for management of symptomatic Gartner cysts.

Oesophageal variceal banding: report of the first eight cases in Kenya.

Twenty variceal banding sessions were performed in eight patients between February 1995 and September 1996. A total of 69 rings were used to band the varices and at each session between two to six rings were used. Two of the eight had active bleeding and both underwent variceal banding to successfully arrest their bleeding as inpatients. Sixteen other variceal banding sessions were performed on an outpatient basis to obliterate their varices. Four of the eight patients had had sclerotherapy before and varices were still present. No acute or long term complications were noted. In one patient, variceal banding could not be performed as he developed stridor upon placement of the overtube. All the patients had advanced varices (Grade III or IV) and extended for more than 15 cms in the oesophagus. Endoscopic variceal obliteration remains the treatment of choice for patients with portal hypertension with variceal bleeding. Variceal banding is associated with a superior outcome when compared with sclerotherapy; the variceal kill time is shorter, infective complications less, rebleeding occurs less commonly and transfusion requirements are lower.

[Percutaneous treatment of simple kidney cysts]. / Traitement per-cutané des kystes simples du rein.

Percutaneous treatment of renal cysts is an effective and minimally invasive alternative to surgery for the treatment of simple, symptomatic renal cysts or cysts complicated by renal stones or hydronephrosis. Moderately large cysts and parapelvic cysts should be treated by sclerotherapy, while very large and peripheral cysts should be resected percutaneously. A series of 29 cysts was treated: 6 percutaneous resections, 22 scleroses, 1 simple puncture-aspiration. Pain relief was obtained in 96% of cases. Resolution of hydronephrosis and renal stones was obtained in 100% of cases. The morbidity (infection, haematoma) was low (10%), but 9 patients (32%) presented with a small residual cavity which, in 1 case, evolved towards a true recurrence of the cyst. The long-term outcome of these asymptomatic residual cavities is unknown.

European guidelines for sclerotherapy in chronic venous disorders.

AIM: Sclerotherapy is the targeted chemical ablation of varicose veins by intravenous injection of a liquid or foamed sclerosing drug. The treated veins may be intradermal, subcutaneous, and/or transfascial as well as superficial and deep in venous malformations. The aim of this guideline is to give evidence-based recommendations for liquid and foam sclerotherapy. METHODS: This guideline was drafted on behalf of 23 European Phlebological Societies during a Guideline Conference on 7-10 May 2012 in Mainz. The conference was organized by the German Society of Phlebology. These guidelines review the present state of knowledge as reflected in published medical literature. The regulatory situation of sclerosant drugs differs from country to country but this has not been considered in this document. The recommendations of this guideline are graded according to the American College of Chest Physicians Task Force recommendations on Grading Strength of Recommendations and Quality of Evidence in Clinical Guidelines. RESULTS: This guideline focuses on the two sclerosing drugs which are licensed in the majority of the European countries, polidocanol and sodium tetradecyl sulphate. Other sclerosants are not discussed in detail. The guideline gives recommendations concerning indications, contraindications, side-effects, concentrations, volumes, technique and efficacy of liquid and foam sclerotherapy of varicose veins and venous malformations.
