Percutaneous treatment of simple renal cysts with 24-h-interval ethanol sclerotherapy / Tratamento percutâneo de cistos renais simples por escleroterapia com etanol em intervalo de 24 horas

Abstract Objective: To investigate the efficacy of 24-h interval multiple-session ethanol sclerotherapy for the treatment of simple renal cysts. Materials and Methods: The study sample included 58 patients (mean age, 65.37 ± 11.95 years). We included 76 simple renal cysts that were treated with percutaneous aspiration with a minimum of two sessions of 95% ethanol sclerotherapy in a 24-h interval between sessions. Patients were evaluated at 1, 3, and 6 months after the intervention for the efficacy of the treatment. Treatment success was defined as a complete regression of a cyst or a > 50% reduction in its volume, with no recurrence of symptoms. Results: The mean preprocedural cyst size was 72.98 ± 25.14 mm, and the mean preprocedural cyst volume was 205.76 ± 244.15 mL. The mean volume of ethanol used in the first sclerotherapy session was 62.76 ± 30.71 mL. The mean fluid accumulation in the cysts at the end of the first 24-h interval was 4.66 ± 7.13 mL. The mean quantity of ethanol used in the second sclerotherapy session was 26.48 ± 22.2 mL. A third sclerotherapy session was required in only 10 (13.2%) of the cysts. The mean follow-up period was 52.84 ± 37.83 months. The rate of complete regression was 97.4% for the whole sample at the end of the follow-up. Conclusion: Ethanol ablation with 24-h intervals is a safe and effective treatment option in the minimally invasive percutaneous treatment of simple renal cysts.

Vascular sclerosing effects of bleomycin on cutaneous veins: a pharmacopathologic study on experimental animals

Abstract: Background: Varicose veins and the complications of venous disease are common disorders in humans. Objective: To study the effects of bleomycin as a potential new sclerosing agent and its adverse events in treating varicose veins. Methods: Bleomycin-loaded liposomes 0.1ml was injected in the dorsal ear veins of white New Zealand rabbits. Sodium tetradecyl sulfate was used as a positive control. Normal saline was used as negative control. The blood vessels of the treated ears were photographed before and at one hour and two, eight and 45 days after treatment. Biopsies from the treated areas were obtained for histological examination. Blood samples were collected to determine any possible toxicity. Results: Bleomycin by itself was ineffective; therefore, liposomes were used as a vector to deliver bleomycin to the vein lumen. Subsequently, bleomycin started showing its sclerosing effects. Toxicity monitoring showed no apparent hematologic, pulmonary, hepatic or renal toxicities. This study revealed that bleomycin induced vasculitis, which led to vascular occlusion, which was observed on day 1 and day 8. No bleomycin-related injury was noted by histopathological examination of lung sections. The calculation of the lung/body weight coefficient indicated that edema was present in the experimental groups compared with the negative and positive controls. Study limitations: Relatively small number of experimental animals used. Conclusions: This study showed that bleomycin-loaded liposomes were able to induce vasculitis and vascular occlusion without any toxicity or complications. It might be useful, hence, to treat patients suffering from Varicose veins and other ectatic vascular diseases with this agent.

A escleroterapia com espuma guiada por ultrassom tem ganhado espaço no tratamento da insuficiência venosa crônica secundária a varizes dos membros inferiores. Trata-se de procedimento ambulatorial, de baixo custo e sem necessidade de afastamento das atividades habituais. Apresenta bons resultados clínicos, especialmente nos estágios mais avançados da doença. Quando bem aplicada, apresenta baixas taxas de complicações maiores. Porém, a técnica apresenta altas taxas de recanalização no médio e longo prazo, e seu mecanismo ainda não é totalmente compreendido. O presente artigo descreve um caso de fístula arteriovenosa em segmento de recanalização de veia safena magna, após escleroterapia com espuma guiada por ultrassom, e identificada por exame ultrassonográfico de vigilância pós-procedimento.

Ultrasound-guided foam sclerotherapy has become widespread in the treatment of chronic venous insufficiency secondary to varicose veins. It is a low-cost, outpatient procedure that does not require medical leave. It has demonstrated good clinical results, especially in the more advanced stages of the disease. When employed correctly, it results in low rates of major complications. However, the technique exhibits high recanalization rates over mid and long-term follow up. Additionally, the recanalization mechanism has not yet been explained. This article describes an arteriovenous fistula in a recanalized segment of great saphenous vein previously treated with ultrasound-guided foam sclerotherapy that was detected during post-procedure follow-up with ultrasound.

Intrauterine therapy for macrocystic congenital cystic adenomatoid malformation of the lung

OBJECTIVE: To report on our experiences with thoracoamniotic shunting and/or the injection of a sclerosing agent (OK-432) to treat fetuses diagnosed with macrocystic congenital cystic adenomatoid malformation (CCAM) of the lung. METHODS: A retrospective study was undertaken in six fetuses with macrocystic CCAM at our institute that had been confirmed by postnatal surgery between August 1999 and January 2012. RESULTS: Six fetuses that had been diagnosed with macrocystic CCAM were analyzed. The median gestational age at diagnosis was 23.5 weeks (range, 19.5-31.0 weeks), and at the time of primary treatment was 24.0 weeks (range, 20.5-31.0 weeks). The mean size of the largest cyst at the initial assessment was 42.5+/-15 mm. Four fetuses were associated with mediastinal shifting, and one also showed fetal hydrops. All fetuses underwent a shunting procedure within the cysts, one case among them was also treated with OK-432. After the completion of all procedures, the mean size of the largest cyst was all decreased (14.2+/-12 mm). The median gestational age at delivery was 38.0 weeks (range, 32.4-40.3 weeks). All of the newborns underwent the surgical resection at a median age of 6 days (range, 1-136 days) and are currently doing well without any complications. CONCLUSION: We suggest that intrauterine decompression therapy to manage fetal macrocystic CCAM is recommendable treatment for good perinatal outcome.

Objective To assess the clinical efficacy of foam sclerotherapy with lauromacrogol for varicose veins of the lower extremities.Methods During the period from February to July 2011,we retrospectively analyzed 20 patients with varicose veins of the lower extremities,who were treated with lauromacrogol foam sclerosing agent injected directly at varicose veins,and in 5 extremities injected at the great saphenous vein(GSV) through a catheter at the same time.Elastic bandages were applied at the site of the injected varicosities after the therapy.The clogging of the varicose veins,the improvement of the clinical symptoms and the adverse reaction were observed. Results Lauromacrogol foam sclerosing agent was successfully injected under the guidance of fluoroscopy in 20 patients with 28 affected extremities. The average volume of foam sclerosing agent in each affected extremity was 7.8 ml. All patients presented selflimiting minor complications,including swelling and pain,which was obviously alleviated by the externallyapplied Mucopolysaccharide Polysulfate Cream.Two patients presented cough that was relieved after inhaling oxygen. Most of treated varicosities demonstrated pigmentation after the first week, which gradually disappeared after the four-month use of vitamin E capsule.A second foam sclerotherapy was carried out for 3 affected extremities of 3 patients two months after the first therapy. Two cases of leg venous ulcer were healed within a few weeks.All patients could walk immediately with no deep vein thrombosis,pulmonary embolism,anaphylaxis,or transient visual disturbance. Obvious abnormal varicose veins as well as the soreness and fatigue of the lower extremities disappeared in all patients at the 10th-month follow-up.The grading of the disease was significantly improved by the treatment (Z =5.103,P ＜ 0.01 ).Conclusions The efficacy of lauromacrogol foam sclerosing agent in the treatment of varicose veins of the lower extremities is confirmed,with advantages of lower complication,ease of treatment,repeatability,and outpatient treatment.the filling-defects technique under fluoroscopy is a method for tracing the sclerosing foam,and can effectively prevent the decp vcin thrombosis.

Efeito do tempo da compressão mecânica extrínseca após escleroterapia em veias de orelhas de coelhos / Effect of the period of extrinsic mechanical compression following sclerotherapy in veins in rabbit ears

PURPOSE: Research whether a post-sclerotherapy venous compression period of up to 120 hours is sufficient to avoid reperfusion in treated veins; whether there is a relationship between the inflammatory intensity in venous walls and adjacent tissue and the size of venous thrombosis; whether the intensity of the post-sclerotherapy inflammation varies with the period of compression; whether there is a relationship between the presence of hemosiderin in the tissues adjacent to the sclerosing blood vessels and venous blood clots. METHODS: Twenty eight rabbits, all male, were utilized, distributed into four groups (0, 24, 72 and 120). All the animals were administered with 0.25 ml of 1 percent polidoconal solution and, as a control, 0.25 ml of 0.9 percent sodium chloride solution in the marginal dorsal vein of the right and left ears, respectively. Mechanical compression was applied to the perfused stretch of the vein, except for the animals in group 0. The period of compression varied from 0 to 120 hours in the groups. An anatomopathological examination of the section of the right and left marginal dorsal veins of all the animals was conducted. RESULTS: There was no significant difference among the various compression periods, both in terms of the degree of vein thrombosis and in the inflammatory intensity in both ears of the various groups. A positive and significant correlation was observed between the inflammatory intensity and the size of the thrombus and in the occurrence of thrombi and hemosiderin. CONCLUSIONS: A compression period of up to 120 hours is not sufficient to prevent reperfusion in sclerosing blood vessels. The intensity of tissue inflammation is related to the size of the thrombus, but not to the compression period. The presence of hemosiderin in the tissues adjacent to the vessels subjected to sclerosis is related to the presence of venous coagulation.

OBJETIVO: Pesquisar se o tempo de compressão venosa de até 120 horas pós-escleroterapia é suficiente para evitar reperfusão nas veias tratadas; se há relação entre a intensidade inflamatória na parede venosa e tecidos adjacentes e o tamanho do trombo venoso; se a intensidade da inflamação pós-escleroterapia varia com o tempo de compressão; se há relação entre a presença de hemossiderina nos tecidos adjacentes ao vaso esclerosado e coágulo venoso. MÉTODOS: Utilizaram-se 28 coelhos, machos, distribuídos em quatro grupos (0, 24, 72 e 120). Em todos os animais foram administrados 0,25 ml de solução de polidocanol 1 por cento e, como controle, 0,25 ml de solução de cloreto de sódio 0,9 por cento na veia marginal dorsal das orelhas direita e esquerda, respectivamente. Realizou-se compressão mecânica em trecho da veia perfundida, exceto nos animais do grupo 0. O tempo de compressão variou de 0 a 120 horas nos grupos. Realizou-se exame anatomopatológico de trecho das veias marginais dorsais direita e esquerda de todos os animais. RESULTADOS: Não houve diferenças significativas nos diversos tempos de compressão, tanto no grau de trombose venosa como na intensidade inflamatória, em ambas as orelhas, nos diversos grupos. Observou-se correlação positiva e significativa entre intensidade inflamatória e tamanho do trombo e na ocorrência de trombos e hemossiderina. CONCLUSÕES: O tempo de até 120 horas de compressão não é suficiente para evitar reperfusão nos vasos esclerosados. A intensidade da inflamação nos tecidos tem relação com o tamanho do trombo, mas não com o tempo de compressão. A presença de hemossiderina nos tecidos adjacentes ao vaso submetido à esclerose está relacionada com a presença de coágulo venoso.

Síndrome de Klippel-Trenaunay-Weber: associação do tratamento operatório à escleroterapia por espuma / Klippel-Trenaunay-Weber syndrome: association of operative treatment with foam sclerotherapy

A Síndrome de Klippel-Trenaunay-Weber representa a associação de hemangiomas planos, ectasias venosas e hipertrofia do segmento corpóreo afetado. Apresenta-se o caso de um paciente de 39 anos, sexo masculino, seguido desde 1993 no serviço da Disciplina de Cirurgia Vascular da Escola Paulista de Medicina (Unifesp), por quadro inicial da síndrome em membro inferior esquerdo. O paciente foi tratado apenas por elastocompressão e medidas gerais. Neste período, ele evoluiu com piora da estase venosa, da hipertrofia óssea e da hiperpigmentação de pele. Na ultrassonografia Doppler colorida venosa dos membros inferiores havia perviedade do sistema venoso profundo, hiperfluxo venoso, insuficiência segmentar de veia safena magna com sinais de tromboflebite e tributárias insuficientes. Indicou-se, para a melhora da estase venosa, ligadura da junção safeno-femoral esquerda e escleroterapia (polidocanol 3 por cento) retrógrada da mesma, com exérese das ectasias venosas. O paciente recebeu alta hospitalar no primeiro dia pós-operatório e atualmente está em acompanhamento ambulatorial com melhora significativa dos sintomas.

The Klippel-Trenaunay-Weber Syndrome is the association of hemangioma, venous ectasia, and hypertrophy of the affected body segment. We report the case of a 39-year-old male followed-up since 1993 due to onset of symptoms in the left lower limb. He was treated only with the use of elastic stockings and general measures. Over the years, he had worsening of venous stasis, of bone hypertrophy, and of skin hyperpigmentation. Color-coded Doppler ultrasonography of the lower limbs showed patency of the deep venous system, venous overflow, segmentar insufficiency of the greater saphenous vein with signs of thrombophlebitis, and insufficient tributary veins. In order to improve venous stasis, ligation of the left sapheno-femoral junction and retrograde foam sclerotherapy (polidocanol 3 percent) with resection of tributary veins were performed. The patient was discharged in the first postoperative day and has been followed as an outpatient, presenting significant improvement of the symptoms.
