Experimental study on the relationship between foam pressure difference and foam stability / 生物医学工程学杂志

Foam stability affects the efficacy and incidence of side effects of foam sclerotherapy. Exploring the relationship between foam pressure difference and foam stability can provide ideas and basis for obtaining more stable foam. In the experiment, sodium cod liver oleate foam was selected, and poloxamer 188 (concentration of 0%, 4%, 8%, 12%) was added to realize the change of foam pressure. By using the self-written program to process the foam pictures, the foam pressure difference and the relationship between the foam stability indicators (water separation rate curve, half-life) and the foam pressure difference were obtained. The results showed that at first the foam pressure increased with the increase of the concentration, and then it decreased with the increase of the concentration and reached a peak at the concentration of 4%. The foam pressure difference decreases continuously with the increase of decay time. When the additive concentration is low, the foam average pressure difference increases. And if the additive concentration is too high, the foam average pressure difference decreases. The smaller the foam pressure difference is, the better the foam stability is. This paper lays a foundation for the research on the stability of foam hardener.

Resección quirúrgica de tapón de cianoacrilato variceal infectado posterior a esclerosis endoscópica de várices gástricas. Caso clínico

In patients with actively bleeding gastric varices, the treatment of choice is the endoscopic use of sclerosing agents such as cyanoacrylate. We report a 69-year-old man who, after being treated with cyanoacrylate, suffered from recurrent febrile episodes. After an extensive study and broad-spectrum antibiotic treatment, discarding other presumably infectious focus, the superinfection of the cyanoacrylate plug was suspected, and its surgical removal was decided. A partial gastrectomy of the gastric fundus, a splenectomy, and a distal pancreatectomy were performed. The patient evolved without fever and without new episodes of bacteremia, but with decompensation of his cirrhosis manifested by ascites, spontaneous bacterial peritonitis, pneumonia, and collections in the pancreatic bed. These complications were managed with medical treatment consisting in a long course of broad-spectrum antibiotics. Thereafter, the patient evolved satisfactorily.

Management of malignant pleural effusion (MPE) in a Tertiary Hospital in a low-income-country: challenges and prospects

Background: In the West African sub-region, significant morbidity and mortality are known to affect patients with malignant pleural effusion (MPE) but are highly under reported unlike USA, Europe or South Africa. Aim/Objective: To review cases of MPE in our tertiary hospital in the last 13 years with a view to determining the challenges and prospects. Materials and Method: This is a retrospective study spanning over a decade from January, 2007 to December, 2019. Malignant pleural effusion from various neoplasms constitutes the commonest thoracic malignancy in our tertiary hospital. After 13 years of management of such patients, we reviewed the datafrom the hospital record's department. The data obtained were demography, aetiology, total number of pleural fluid specimens for cytology and pleural biopsies submitted for histology, pleurodesis and other treatment modalities. Result: 211 patients with MPE were admitted and managed during the period under review. Of these numbers, 135(64.0%) were confirmed cytologically positive (MPE). 76(36.0%) tested falsely negative and were initially regarded as paramalignant, later confirmed MPE. The age affected was from 7 to 81 years with a mean of 44 years. Of 211 patients with MPE, 94 were males while 117 were females, with a male to female ratio of 4:5. Aetiologically, metastatic breast cancer was the highest followed by advance lung cancer. Conclusion: Submission of insufficient samples resulted in false negative cytology. Review of recurrent pleural effusion and exophytic tumour at the sites of CTTD resulted in late diagnosis of MPE. Additionally, prolonged hospital stay awaiting CTTD and cytology results are among the challenges

Sclerotherapy of benign oral vascular lesions with non-diluted ethanolamine oleate / Escleroterapia de lesiones vasculares orales benignas con oleato de etanolamina no diluido

Benign oral vascular lesions are anomalies characterized by the blood vessels proliferation or malformation and the treatment with the sclerosing agent ethanolamine oleate acts irrigating the vessel producing a sterile inflammatory response. The objective of this study was to report and discuss the results from treatment of benign oral vascular lesions with non-diluted ethanolamine oleate through the analysis of clinical records. The sample was composed by the selection of twenty-six patients (12 male and 14 female), with oral vascular malformations. All lesions were treated with intralesional injections of undiluted ethanolamine oleate. These patients attended in Oral Medicine outpatient clinic of the Federal University of Paraná between the years of 2011 to 2015. The average age was 60.65 years, with a higher prevalence for women. The majority of the individuals had one lesion and its location was mostly in the lower lip. The main complaint was about a physical discomfort. The lesions had the average size of 6.52 mm and received a median number of 2.32 applications. Only one patient reported feeling pain in the postoperative week. In most cases the resolution of the lesion was considered partial. Follow-up was obtained up to one month after the end of treatment. The sclerotherapy with undiluted ethanolamine oleate shows acceptable results in the treatment of small benign oral vascular lesions with a few minor side effects.

Las lesiones vasculares orales benignas son anomalías caracterizadas por la proliferación o malformación de los vasos sanguíneos y el tratamiento con el agente esclerosante etanolamina oleato actúa irrigando el vaso produciendo una respuesta inflamatoria estéril. El objetivo de este estudio fue informar y discutir los resultados del tratamiento de lesiones vasculares orales benignas con oleato de etanolamina no diluido a través del análisis de historias clínicas. La muestra estuvo compuesta por la selección de veintiséis pacientes (12 hombres y 14 mujeres), con malformaciones vasculares orales. Todas las lesiones fueron tratadas con inyecciones intralesionales de oleato de etanolamina sin diluir. Estos pacientes acudieron a la clínica ambulatoria de Medicina Oral de la Universidad Federal de Paraná entre los años 2011 a 2015. La edad promedio fue de 60,65 años, con una mayor prevalencia para las mujeres. La mayoría de los individuos tenían una lesión y su ubicación era principalmente en el labio inferior. La queja principal era sobre una molestia física. Las lesiones tenían un tamaño promedio de 6,52 mm y recibieron una mediana de 2,32 aplicaciones. Solo un paciente informó haber sentido dolor en la semana postoperatoria. En la mayoría de los casos, la resolución de la lesión se consideró parcial. El seguimiento se obtuvo hasta un mes después del final del tratamiento. La escleroterapia con oleato de etanolamina sin diluir muestra resultados aceptables en el tratamiento de pequeñas lesiones vasculares orales benignas con algunos efectos secundarios menores.

Efficacy of Percutaneous Sclerotherapy in Low Flow Venous Malformations / 신경중재치료의학

PURPOSE: We analyzed results of percutaneous sclerotherapy for venous malformations (VMs) in head, neck and extremities. MATERIALS AND METHODS: Thirty-five patients with head and neck and extremities VM treated by sclerotherapy with bleomycin and sodium tetradecyl sulphate (STS) were retrospectively reviewed. A pre-treatment magnetic resonance imaging was done for all patients to diagnose the lesion. Each lesion received 1 to 11 sessions (average, 2.7; standard deviation [SD], 2.03). We evaluated percentage reduction in swelling size and a Likert scale review of subjective feelings of the patients. RESULTS: Sixteen had a complete obliteration; by sclerotherapy alone (n=13) and surgery after a 75% reduction (n=3). Ten patients had a significant reduction up to 75% and three patients by 50%. Four had a minimal decrease with reduction of 25% or less. Follow-up duration of the patients varied from a minimum of 6 months up to 3 years (average, 15.7 months; SD, 7.8 months). Of all patients, three refused further treatment and were lost to follow-up, while another two were referred to a dermatologist. Thirteen patients reported feeling excellent after the sessions. Eight patients claimed to feel slightly better compared to before the sessions started. Only three patients complained of feeling the same before and after the sessions. None of the patients still in follow-up have reported a recurrence of a lesion thus far. CONCLUSION: Sclerotherapy using bleomycin and STS as sclerosants is a safe and effective primary treatment for VMs in the head and neck as well as in extremities.

Colgajo libre de piel para defecto de cubrimiento de piel peneana ­ reporte de caso / Skin Free Flap for Penile Skin Covering Defect ­ Case Report

Introducción Reportar el caso de un paciente con lipogranuloma esclerosante de pene llevado a corrección de curvatura peneana compleja, con injerto de espesor parcial y posterior retracción secundaria, que generó curvatura peneana impidiendo el coito y que al momento de corrección quirúrgica, se generó un defecto de cubrimiento dérmico que requirió el uso de colgajo con piel de la pared abdominal. Materiales y Métodos Hombre de 46 años con antecedente de resección de lipogranuloma esclerosante en cara dorsal del pene resecado en el año 2006 y disfunción eréctil en manejo con terapia intracavernosa con prostaglandina E2; con necesidad de injertos de piel de abdomen en 2 oportunidades para cubrimiento de defecto de piel, con posterior fibrosis y curvatura peneana dorsal de aproximadamente 60° asociado a dolor con la erección. Llevado a corrección de curvatura peneana compleja en Hospital Universitario Mayor- Méderi. Se realiza plicatura de la túnica albugínea con técnica de Yachia hasta la verificación de corrección de curvatura dorsal en un 90%. Se identifica área con defecto de cubrimiento, por lo cual se levanta colgajo en región hipogástrica abdominal y se realiza anclaje del colgajo en borde distal del defecto de cubrimiento. Seis semanas después, es llevado a segundo tiempo quirúrgico, con liberación y remodelación del colgajo y se realiza el anclaje del colgajo en el borde proximal del defecto. Tres meses después, se revalúa el paciente encontrándose cubrimiento completo del área cruenta en región dorsal del pene. Se induce erección con alprostadil intracavernoso evidenciándose curvatura peneana dorsal de menos de 5°. Discusión Los pacientes con lipogranuloma esclerosante del pene generan placas en túnicas peneanas que al momento de ser resecadas, pueden requerir el uso de segmentos de piel para cubrimiento con injertos o colgajos pediculados en un terreno con alta probabilidad de daño por isquemia de dichos tejidos. En los casos en los que ocurre contracción del injerto se generan curvaturas peneanas que en caso de que impidan el coito requieren corrección de la misma. El uso de injertos autólogos o aloinjertos ha presentado resultados satisfactorios, sin embargo, puede requerir dos tiempos quirúrgicos para la obtención de tejido. En pacientes en quienes la piel peneana no es suficiente para cubrir el defecto, la segunda opción es la piel escrotal, que conserva características similares, así como una excelente vascularización. Cuando no se cuenta con piel escrotal en buen estado, se usa un injerto de piel de espesor total como última opción con resultados satisfactorios. Conclusiones Actualmente, el uso de piel de abdomen en esos defectos de piel no tiene amplia acogida dada la presencia de anexos dérmicos que terminan generando un aspecto estético no óptimo, sin embargo, se evidencia en este caso, que es un tejido que se adapta fácilmente a su nueva ubicación y permite el fin último, que es lograr una adecuada función del órgano receptor.

Introduction Report the case of a patient with penile sclerosinglipogranuloma who was taken to corrrection of complex penile curvature with split-thickness graft with later secondary retraction that caused penile curvature preventing intercourse and during surgical mangement generated a skin coverge defect that required the use of free skin flap from the abdominal wall. Material and Methods 46 year old men with a history of surgical resection of sclerosinlipogranuloma in dorsal penile resected in 2006 and erectile dysfunction managed with intracavernous therapy with prostaglandin E2; that required abdominal skin grafts in 2 opportunities for skin defect coverage, with subsequent fibrosis and dorsal penile curvature of ∼60 degrees associated with pain during erection. Carried complex penile curvature correction in Hopsital Universitario Mayor ­ Méderi. Plication of the tunica albuginea with Yachia technique is performed until correction of dorsal curvature in 90%. Coverage defect area is identified, so that flap of hypogastric abdominal region is lifted and anchored in the distal edge of coverage defect. 6 weeks later is taken to second surgical procedure, with release and remodeling of the flap and anchorage of it in the proximal edge of the defect. 3 months after, the patient is reassessed finding complete coverage of the area on the dorsal surface of the penis. Erection is induced by intracavernousalprostadil showing dorsal penile curvature of less than 5 degrees. Discussion Patients with sclerosing penile lipogranuloma undergo plaques in penile layers that when resected may require the use of skin grafts or pedicle flaps for coverage in an area with high probability of ischemia in these tissues. In cases in which the graft contraction result in penile curvature, that in the event of preventing coitus require surgical correction thereof. The use of autologous grafts or allografts have shown satisfactory results, but may require two surgical procedures to obtain adecuate tissue. In patients in whom the penile skin is not enough to cover the defect, the second option is scrotal skin, which retains similar characteristics, as well as an excellent vascularization. When there is no adecuate scrotal skin, full thickness skin grafting as last option is used with satisfactory results. Conclusions Currently, the use of abdominal skin in these skin defects has no wide acceptance because of the presence of dermal annexes, ending in a suboptimal aesthetic appearance, however, it is evident in this case, is a tissue that is easily adapted to its new location and allows the latter, which is to achieve adequate organ receptor function.

Escleroterapia em lesões vasculares de boca: relato de dois casos clínicos / Sclerotherapy in vascular lesions of the mouth: report of two clinical cases

O hemangioma é uma neoplasia de comportamento benigno, determinada pela proliferação anormal de vasos sanguíneos. São lesões assintomáticas, porém, seu crescimento progressivo pode acarretar danos traumáticos locais, ocasionando dor, ulcerações e até sangramentos, que, dependendo da localização, se tornam de difícil controle, principalmente quando de natureza arterial. Com considerável incidência na região de cabeça e pescoço e na cavidade bucal, acomete mais frequentemente a região de mucosa jugal, lábios e língua. Tendo em vista a sua relevância clínica, por estar presente na sua área de atuação e ser relativamente comum, o conhecimento acerca dessa neoplasia benigna é de fundamental importância ao cirurgião-dentista. Entre os recursos terapêuticos, a escleroterapia química tem sido empregada, apresentando resultados satisfatórios tanto clínicos quanto estéticos. Objetivo: apresentar as características clínicas do hemangioma, os métodos de diagnóstico e o tratamento realizado por meio de escleroterapia química. Relato de caso: são descritos dois casos clínicos de hemangiomas, diagnosticados em duas pacientes do sexo feminino, localizados um em lábio superior e outro em mucosa jugal, tratados por meio de injeção de solução esclerosante. Considerações finais: em ambos os casos, foi possível proporcionar a involução das lesões mediante procedimentos não cirúrgicos, favorecendo, no período pós-operatório, o conforto e a estética, demonstrando a eficiência e a segurança na utilização do oleato de monoetanolamina a 5% (Ethamolin ®). (AU)

Hemangioma is a neoplasm of benign behavior, determined by abnormal proliferation of blood vessels. They are asymptomatic lesions, however, their progressive growth can cause local traumatic injuries, causing pain, ulcerations and even bleeding, which, depending on the location, becomes difficult to control, especially when of an arterial nature. With a considerable incidence in the head and neck region, in the oral cavity, it most frequently affects the region of jugal mucosa, lips and tongue. Due to its clinical relevance, because it is present in the area of practice of the dental surgeon and is relatively common, knowledge about this benign neoplasm is of fundamental importance. Among the therapeutic resources, chemical sclerotherapy is employed presenting satisfactory clinical and aesthetic results. Objective: the purpose of this study is to present the clinical characteristics of hemangioma, the diagnostic methods and the treatment performed through chemical sclerotherapy. Case report: this article describes the description of two clinical cases of hemangiomas diagnosed in two female patients, one located in the upper lip and the other in the jugal mucosa treated with sclerosing solution injection. Final considerations: in both cases, it was possible to provide the involution of the lesions by non-surgical procedures, favoring, in the postoperative period, comfort and aesthetics, demonstrating the efficiency and safety in the use of 5% monoethanolamine oleate (Ethamolin®).

Cerebrovascular ischemia following ultrasound-guided foam sclerotherapy / Isquemia cerebral após escleroterapia com espuma guiada por ultrassom

Cerebral ischemia is a very rare and harmful complication of ultrasound-guided foam sclerotherapy for treatment of varicose veins. This case describes a documented cerebrovascular ischemia in Broca's area following ultrasound-guided foam sclerotherapy. Less than one hour after intravenous injection of 10 ml of sclerosing foam, an otherwise healthy woman experienced aphasia without any other signs of neurological changes. When she arrived home, a complete inability to talk was observed. The event was misdiagnosed by another doctor as an allergic reaction. Next morning she came to the office to report the allergic reaction, where an appropriate diagnosis was made. She recovered just two days after the injection, but signs of recent cerebral ischemia were seen in Broca's area on magnetic resonance and transesophageal bubble study echocardiogram revealed a patent foramen ovale. Although rare, we must make great effort to prevent these events instead of treating them

A isquemia cerebral é uma complicação muito rara e perigosa da escleroterapia com espuma guiada por ultrassom no tratamento de varizes. Este caso descreve uma isquemia cerebral da área de Broca após escleroterapia com espuma guiada por ultrassom. Menos de uma hora após injeção de 10 mL de espuma, uma até então saudável mulher apresentou afasia, sem quaisquer outros sinais neurológicos. No caminho para casa, uma completa incapacidade de fala foi observada. Levada ao hospital mais próximo, foi diagnosticada com reação alérgica. Na manhã seguinte, compareceu ao consultório para relatar a reação alérgica, quando um correto diagnóstico foi feito. Ela ficou recuperada dois dias depois do procedimento, mas uma ressonância magnética mostrou sinais de isquemia recente da área de Broca e um ecocardiograma transesofágico mostrou um forame oval patente. Embora raros, devemos concentrar nossos esforços em prevenir tais eventos para que não precisem de tratamento

Glicose como causa e tratamento de necrose cutânea / Glucose as a cause of and treatment for cutaneous necrosis

A escleroterapia continua sendo um dos procedimentos mais executados pelos cirurgiões vasculares brasileiros. O conhecimento das suas complicações é imprescindível para que possamos evitá-las. Os efeitos colaterais graves desse método de tratamento para as telangiectasias dos membros inferiores são raros e frequentemente associados a um erro técnico ou à dosagem injetada. São predominantemente locais, apresentando-se, algumas vezes, como uma situação de difícil resolução. Relatamos um caso de formação de necrose cutânea após escleroterapia química com glicose hipertônica (75%) e sua cicatrização utilizando preparação tópica contendo vaselina e glicose 60%, cujo resultado estético foi satisfatório

Sclerotherapy remains one of the procedures most frequently performed by Brazilian vascular surgeons. Knowledge of its complications is indispensable to enable us to avoid them. The severe side effects of this method of treatment for telangiectasias of the lower limbs are rare and are often associated with technical errors or the dose injected. Complications are predominantly local, but are sometimes difficult to resolve. We report a case of formation of cutaneous necrosis after chemical sclerotherapy using hypertonic glucose (75%), which healed when treated with a topical preparation containing vaseline and 60% glucose, with satisfactory esthetic results

Intravascular and intraparenchymatous hepatic segmentary sclerosis

Abstract Purpose: To evaluate the morphological effects of injected sclerosing agents into the liver. Methods: This study was performed on twenty dogs, distributed into five groups: Group 1 (n = 5) - control, Group 2 (n = 5) - injection of 50% glucose solution inside hepatic parenchyma and animals followed during seven days, Group 3 (n = 10) - injection of ethanol inside hepatic parenchyma and animals distribution into two subgroups Subgroup 3A (n = 5) - followed during 24 hours and subgroup 3B (n = 5) - followed during seven days (group 3B), Group 4 (n = 5) - ethanol injection inside left portal vein branch and followed during 24 hours. Livers were macroscopically evaluated, submitted to hepatic arteriography and portography, then histology. Results: All animals in Group 4 died within 23 hours due to diffuse hepatic necrosis. The animals of groups 2 and 3 had a satisfactory evolution. Fibrosis formed in the segment reached by the sclerosant solution and interruption of the contrast flow injected into the portal system. Conclusion: Intrahepatic parenchymal ethanol injection is well tolerated and causes sclerosis restricted to a specific segment; however, intraportal ethanol injection causes massive hepatic necrosis and can lead to death.

Tratamento de hemangioma labial por meio da escleroterapia / Labial hemangioma treatment through sclerotherapy: case report

O hemangioma é considerado como uma neoplasia vascular benigna, caracterizado por uma fase de crescimento rápido, com proliferação de células endoteliais, seguida por uma estabilização gradual. A principal queixa dos pacientes portadores dessa neoplasia é referente à estética e, por esse motivo, a escleroterapia vem sendo uma boa opção de tratamento para obter resultados estéticos satisfatórios. Para esse tipo de tratamento, são utilizadas aplicações com oleato de monoetanolamina a 0,05 g/ml (Ethamolin), que promovem a regressão da lesão por fibrose dos espaços endoteliais. No presente artigo, é descrito um relato de caso clínico de uma paciente do sexo feminino, portadora de um hemangioma no lábio superior esquerdo. Foram realizadas três aplicações do agente esclerosante Ethamolin no interior do tumor, até que ele regredisse o suficiente para ser removido cirurgicamente com maior segurança e eficiência. As aplicações com oleato de monoetanolamina proporcionaram a involução do hemangioma de forma rápida e segura, de modo a promover uma esclerose dos vasos tumorais, favorecendo a remoção cirúrgica.

The hemangioma is considered as a benign vascular neoplasm, characterized by a phase of rapid growth, with proliferation of endothelial cells, followed by gradual estabilization. The main complaint of patients with this neoplasm is related to aesthetics and, for this reason, sclerotherapy has been a good treatment option to obtain satisfactory aesthetic results. For this type of treatment, applications with 0.05 g/ml Monoethanolamine Oleate (Ethamolin), which causes regression of the lesion by fibrosis of the endothelial spaces, are used. In the present article a clinical case report of a female patient with a hemangioma in the upper left lip will be described. As a treatment, three applications of the Ethamolin sclerosing agent were performed inside the tumor until it regress to be excised with greater safety and efficiency. The applications with Monoethanolamine Oleate provided a quick hemangioma involution, in order to promote sclerosis of tumor vessels, favoring it surgical removal.

Spontaneously Resolving of Huge Simple Hepatic Cyst / 대한소화기학회지

Simple hepatic cysts are common benign liver lesions that usually have no malignant capability. They are generally asymptomatic and are often found incidentally by abdominal imaging procedures. Treatment becomes necessary, however, when huge hepatic cysts cause symptoms and develop complications, such as hemorrhage, adjacent organ damage, and infection. Several therapeutic options have been performed for symptomatic and huge cysts, including the aspiration of cystic fluid, infusion of various sclerosing agents, and surgical intervention. The optimal management of huge hepatic cysts is controversial and each option has its complications and limitations. This paper reports a case of a 66-year-old woman diagnosed with a simple hepatic cyst 2 years earlier, who was referred to hospital due to abdominal pain. The diagnosis was a huge hepatic cyst with symptoms by abdominal imaging studies. During the follow-up period, the huge cysts resolved spontaneously without treatment.

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.

Resultados preliminares do tratamento de insuficiência venosa grave com termoablação da veia safena magna por técnica endovascular com laser de diodo 980nm desenvolvido no Brasil, associado à escleroterapia com polidocanol / Preliminary results of severe venous insufficiency treatment with thermal ablation of the great saphenous vein by endovascular technique with laser diode 980nm developed in Brazil, associated with sclerotherapy with polidocanol

RESUMO A termoablação endovascular das veias safenas insuficientes com laser é descrita como uma técnica menos invasiva, com resultados semelhantes à cirurgia convencional, porém, com efeitos adversos menos frequentes. A técnica de escleroterapia com espuma de polidocanol ecoguiada vem sendo empregada com a mesma finalidade. A combinação de técnicas pode representar uma alternativa para pacientes mais graves, como os portadores de úlcera varicosa. Um equipamento de laser (denominado VELAS) foi desenvolvido no Centro de Pesquisas em Ótica e Fotônica da USP-São Carlos em convênio com a FMB-UNESP para termoablação endoluminal da veia safena insuficiente. Neste estudo apresentamos os resultados preliminares do uso do aparelho de laser VELAS (diodo MMO 980nm) na termoablação endovascular de veias safenas insuficientes, em portadores de úlcera venosa crônica, associado à complementação com espuma de polidocanol para o tratamento de varicosidades, após uma semana. Os desfechos analisados foram o tempo de cicatrização da úlcera venosa, oclusão das veias tratadas e eventos adversos relacionados aos tratamentos. Foram incluídos 12 pacientes portadores de insuficiência de veia safena e úlcera venosa crônica que aceitaram participar do projeto. Todos foram tratados em regime ambulatorial, com anestesia local e termoablação da veia safena insuficiente (VELAS). Após uma semana da cirurgia, as varicosidades foram esclerosadas com polidocanol espuma (técnica de Tessari). O equipamento laser VELAS nacional apresentou fácil manuseio, oclusão venosa total em 83,3% dos pacientes (em sete dias) e a associação das técnicas foi responsável por uma taxa de cicatrização de feridas de 83,3%, sem ocorrência de eventos adversos.

ABSTRACT The endovenous laser ablation (EVLA) of the insufficient saphenous vein has similar results to open conventional surgery, but less morbidity. The echo-guided polidocanol foam sclerotherapy technique has been used for the same purpose. The combined techniques may play a role for more severe diseases, such as those with varicose ulcers. An EVLA device (called VELAS) has been developed in the Optics and Photonics Research Center of USP-São Carlos in agreement with FMB-UNESP. In this study, we present the preliminary results of the VELAS device (MMO 980nm diode) in patients with chronic venous ulcer, associated with echo-guided polidocanol foam sclerotherapy for the treatment of varicosities. Primary outcomes were healing time of the venous ulcer, occlusion of the treated veins and treatment-related adverse events. We included 12 patients with insufficient saphenous vein and chronic venous ulcer. Initially, we treated all of them with thermoablation of the insufficient saphenous vein (VELAS), on an outpatient basis, with local anesthesia. After one week of the procedure, we sclerosed the varicosities with polidocanol foam (Tessari technique). The national VELAS device was easily handled. Total venous occlusion occurred in 83.3% of the patients (in seven days) and the association of the techniques was responsible for a wound healing rate of 83.3%, with no adverse events.
