BACKGROUND: In natural history of cirrhosis, variceal bleeding is one of the earliest decompensations to happen, and, if adequately managed, survival is improved. Gastric varices have challenges in management due to their location, size and propensity to bleed. The N-butyl 2-cyanoacrylate (NBC) glue application has emerged as definitive therapy in bleeding gastric varices. Here we present our experience with use of NBC in management of gastric and difficult cases of esophageal varices. METHODS: A total of 75 patients underwent NBC glue application for varices which included 69 patients with gastric varices and six patients with esophageal varices. All the procedures were done with flexible endoscope and sclerotherapy needle after due precautionary measures. RESULTS: Hemostasis was varices in all patients after endotherapy. The average quantity of glue used was 2.75±0.95 mL. Complete obliteration with single session of NBC application was achieved in 55 patients. Re-bleeding occurred in five patients within 5 days of index event. 20 patients had in-hospital mortality but none was related to gastrointestinal bleeding. 6-week all-cause mortality was 26 (35%). CONCLUSION: Glue therapy with NBC is a life saving therapy in patients with bleeding gastric varices and esophageal varices not amenable to endoscopic variceal ligation or sclerotherapy.

Resumo Contexto Apesar de todo o investimento na profilaxia primária do tromboembolismo venoso (TEV) em pacientes cirúrgicos nos últimos anos, ainda não existem diretrizes específicas para aqueles que serão submetidos a procedimentos para tratamento de varizes de membros inferiores. Objetivos Avaliar o perfil de conduta de profilaxia do TEV pelos cirurgiões vasculares brasileiros para procedimentos de tratamento de varizes de membros inferiores. Métodos Pesquisa de levantamento por envio de questionário eletrônico a cirurgiões vasculares brasileiros. Os respondentes foram divididos entre os que realizam tratamento de veias safenas por cirurgia convencional e os que realizam termoablação para fim de comparação entre os grupos. Resultados Entre os 765 respondentes, o tratamento de escolha das veias safenas foi a cirurgia convencional para 405 (53%), espuma ecoguiada para 44 (6%) e termoablação (endolaser ou radiofrequência) para 199 (26%). Os cirurgiões que realizam termoablação prescrevem mais farmacoprofilaxia após o procedimento que aqueles que preferem cirurgia convencional (67/199, 34% vs. 112/405, 28%; p = 0,002). O grupo termoablação estratifica o paciente quanto ao risco de TEV com mais frequência que o grupo cirurgia convencional (102/199, 51% vs. 179/405, 44%; p =0,004). Ambos os grupos usam mais frequentemente enoxaparina como medicação para profilaxia, porém o grupo termoablação usa mais anticoagulantes orais diretos proporcionalmente que o grupo cirurgia convencional (26% vs. 10%, p < 0,001). Conclusões Cirurgiões vasculares brasileiros que fizeram o tratamento de veias safenas por termoablação prescrevem farmacoprofilaxia com maior frequência e por um período mais prolongado do que os que realizaram o tratamento por cirurgia convencional.
Abstract Background Despite all the investment in primary venous thromboembolism (VTE) prophylaxis for surgical patients in recent years, there are still no specific guidelines for those who undergo procedures to treat lower limb varicose veins. Objectives To evaluate the profile of VTE prophylaxis practices among Brazilian vascular surgeons conducting lower limb varicose vein procedures. Methods Survey design, sending an electronic questionnaire to Brazilian vascular surgeons. Respondents were divided between those who perform saphenous vein treatment with conventional surgery and those who perform thermoablation for the purpose of comparison between groups. Results Of 765 respondents, 405 (53%) treat saphenous veins with conventional surgery for, 44 (6%) with foam, and 199 (26%) with thermoablation (endolaser or radiofrequency). Surgeons who perform thermoablation prescribed more pharmacoprophylaxis after varicose vein surgery than those who perform conventional surgery (67/199, 34% vs. 112/405, 28%; p = 0.002). The thermoablation group stratifies patients for thromboembolism risk more frequently than the conventional surgery group (102/199, 51% vs. 179/405, 44%; p = 0.004). Both groups use enoxaparin as the most frequent drug for prophylaxis, but the thermoablation group uses proportionally more direct oral anticoagulants than the conventional surgery group (26% vs. 10%, p<0.001). Conclusions Brazilian vascular surgeons who perform saphenous vein treatment by thermoablation prescribe pharmacoprophylaxis more frequently and for a longer period than those who use conventional surgery.

Resumo A regurgitação tricúspide severa é citada como fator associado ao desenvolvimento ou à recidiva de varizes em membros inferiores as quais podem, retrogradamente, apresentar um fluxo pulsátil. O diagnóstico etiológico diferencial desse achado ultrassonográfico deve ser feito com a pesquisa de fístulas arteriovenosas, tendo em vista as diferentes formas de tratamento. Dada a complexidade do estado geral dos pacientes com regurgitação tricúspide, a escolha do tratamento das varizes pulsáteis deve ser individualizada, fruto de uma avaliação multidisciplinar. Fazem parte do arsenal terapêutico todas as técnicas habitualmente empregadas no tratamento de varizes, bem como a associações entre elas a serem escolhidas levando-se em conta a gravidade das manifestações clínicas e o risco cardiovascular envolvido. Relatamos um caso de varizes pulsáteis secundárias a regurgitação tricúspide, diagnosticado durante a suspeita primária de aneurisma de artéria femoral em paciente de 73 anos, com a classificação clínica da doença venosa (CEAP) 4a, oligossintomática, tratada com medidas posturais e elastocompressão.
Abstract Severe tricuspid regurgitation is mentioned as a factor associated with development or recurrence of varicose veins in the lower limbs and may present with retrograde pulsatile flow. Differential etiological diagnosis of this ultrasound finding must include investigation of arteriovenous fistulas, since the treatment methods are different. Given the complexity of the general condition of patients with tricuspid regurgitation, treatment for pulsatile varices should be chosen on a case-by-case basis after multidisciplinary evaluation. All of the techniques commonly used to treat varicose veins are part of the therapeutic arsenal, as well as combinations of them, taking into account the severity of clinical manifestations and the cardiovascular risk involved. We report a case of pulsatile varices secondary to tricuspid regurgitation diagnosed when investigating a primary suspicion of femoral artery aneurysm in a 73-year-old patient, CEAP 4a, oligosymptomatic, who was treated with postural measures and elastic compression.

There are few data on endovascular treatment of anterior nutcracker syndrome and pelvic varices in patients with anterior and posterior renal veins. Our objective is to report a case, identify occurrences and compare diagnosis and treatments. A 42-year-old woman presented with flank and pelvic pain and hematuria. She had anterior nutcracker syndrome and pelvic varices with an anterior and a posterior renal vein. A successful complete endovascular approach was done with stent implantation in the anterior renal vein and left gonadal vein embolisation. After 12-month follow-up, the patient remained asymptomatic with good results on CT. Only two case reports of patients with nutcracker syndrome with anterior and posterior renal veins were identified. In both, a self-expanding stent was implanted in the anterior renal vein. In conclusion, endovascular treatment represents a safe and successful option in patients with nutcracker syndrome and pelvic varices with an anterior and a posterior renal vein.

Parastomal variceal bleeding (PVB) is a serious complication occurring in up to 27% of patients with an ostomy and concurrent cirrhosis and portal hypertension. The management of PVB is difficult and there are no clear guidelines on this matter. Transjugular intrahepatic portosystemic shunt (TIPS), sclerotherapy, and /or coil embolization are all therapies that have been shown to successfully manage PVB. We present a case series with five different patients who had a PVB at our institution. The aim of this case series is to report our experience on the management of this infrequently reported but serious condition. We also conducted a systemic literature review focusing on the treatment modalities of 163 patients with parastomal variceal bleeds. In our series, patient 1 had embolization and sclerotherapy without control of bleed and expired on the day of intervention due to hemorrhagic shock. Patient 2 had TIPS in conjunction with embolization and sclerotherapy and had no instance of rebleed 441 days after therapy. Patient 3 did not undergo any intervention due to high risk for morbidity and mortality, the bleed self-resolved and there was no further rebleed, this same patient died of sepsis 73 days later. Patient 4 had embolization and sclerotherapy and had no instance of rebleed 290 days after therapy. Patient 5 had TIPS procedure and was discharged five days post procedure without rebleed, patient has since been lost to follow-up.

OBJECTIVE: We aimed to evaluate the efficacy of liquid or foam sclerotherapy of varicose veins using venous clinical severity scores and possible complications. METHODS: A total of 318 patients (268 females, 50 males) who were treated with liquid or foam sclerotherapy between January 2012 and December 2012 were included in this study. RESULTS: Skin necrosis was observed in only 6 patients (1. 8%), thrombophlebitis in 10 patients (3. 1%), and hyperpigmentation in 18 patients (5. 6%) in this study group. The mean venous clinical severity score was calculated as: pain score, 1. 23 ± 0.88; varicose vein score,1.85 ± 0. 8; edema score, 0.64 ± 0.77). Pain and edema decreased at the control examination, 1 month after completion of sclerotherapy sessions. Varicose veins completely disappeared after sclerotherapy. While the decrease in edema in the foam sclerotherapy group was significantly less (P<0.001), the decline in pain showed an increasing trend (P=0.069). While skin necrosis did not develop after foam sclerotherapy, rates of pigmentation and local thrombophlebitis were similar (P>0.05). CONCLUSION: In conclusion, we observed that both sclerotherapy methods are effective with a low rate of complications, alleviating the complaints of patients with small varicose veins, and providing considerable improvement in venous clinical severity scores.

RESUMO OBJETIVO: Nosso objetivo foi avaliar a eficácia de líquido ou espuma na escleroterapia de varizes por meio de escores de gravidade clínica venosa e possíveis complicações. MÉTODOS: Um total de 318 pacientes (268 do sexo feminino, 50 do sexo masculino) tratados com escleroterapia com espuma ou líquido entre janeiro de 2012 e dezembro de 2012 foi incluído neste estudo. RESULTADOS: Necrose da pele foi observada em apenas seis pacientes (1,8%), tromboflebite em dez pacientes (3,1%) e hiperpigmentação em 18 pacientes (5,6%) neste grupo de estudo. A média do escore de gravidade clínica venosa foi calculado como: dor pontuação 1,23±0,88, veia varicosa pontuação 1,85±0,8, edema pontuação 0,64±0,77. Dor e edema reduzido no exame de controle um mês após a conclusão das sessões de escleroterapia. Varizes desapareceram completamente após a escleroterapia. Enquanto a diminuição do edema no grupo de escleroterapia com espuma foi significativamente menor (P<0,001), o decréscimo do nível de dor mostrou uma tendência a ser maior (P=0,069). Ainda que necrose da pele não tenha se desenvolvido após escleroterapia com espuma, as taxas de pigmentação e tromboflebite local foram semelhantes (P>0,05). CONCLUSÃO: Observou-se que ambos os métodos de escleroterapia são eficazes, com baixa taxa de complicações, aliviando as queixas de pacientes com varizes pequenas, e proporcionando uma melhora considerável nos escores de gravidade clínica venosa.
