RESUMEN

The current coronavirus pandemic has already taken a great toll globally, causing massive morbidity and mortality. One of its severe forms is a thrombophilic state that can damage several systems. This article reports the case of 60-year-old female patient who presented with mild flu symptoms, which turned out to be a SARS-CoV2 infection, and ended up developing arterial thrombosis with limb ischemia in a private care hospital in Sorocaba, São Paulo, Brazil. Considering this progression, we decided to intervene with low molecular weight heparin and Alprostadil, achieving a good clinical outcome. Our description aims to identify key points and clinical signs that offer evidence of the therapeutic window and a treatment option for coagulatory presentations of COVID-19.

A atual pandemia de coronavírus já gerou danos profundos ao redor do mundo, causando grande quantidade de morbidades e mortes. Uma das manifestações das formas graves da doença é o estado trombofílico, que pode provocar danos em vários sistemas. Este artigo relata o caso de uma paciente do sexo feminino, 60 anos de idade, que foi internada em um serviço hospitalar privado com sintomas gripais inespecíficos leves, mas que progrediu com trombose arterial e isquemia de membros causada pelo SARS-CoV2. Devido à essa evolução, foi optada pela administração concomitante de heparina de baixo peso molecular e Alprostadil, com bom desfecho clínico. Nossa descrição objetiva identificar pontos-chave e sinais clínicos que evidenciem essa janela terapêutica, bem como uma opção de tratamento para as apresentações coagulatórias da COVID-19.

RESUMEN

Resumo Aneurismas da artéria esplênica (AAE) verdadeiros são uma patologia rara, mas potencialmente fatal. São o terceiro aneurisma abdominal mais comum, após aneurismas da aorta e da artéria ilíaca, e representam quase todos os aneurismas de artérias viscerais. Os aneurismas verdadeiros são responsáveis ​​por 60% dos AAEs e afetam as mulheres quatro vezes mais do que os homens, geralmente relacionados a uma descoberta incidental ou sintomática aumentada que coincide com o uso da ultrassonografia na gravidez. Em pacientes grávidas, a mortalidade, após a ruptura, é de 65-75%, com mais de 90% de mortalidade fetal. Têm múltiplas etiologias, e acredita-se que as influências hormonais e as alterações do fluxo portal durante a gestação desempenhem um papel importante no desenvolvimento do AAE. Esta revisão discorrerá sobre sua história, epidemiologia, fisiopatologia, diagnóstico, e as técnicas atuais de tratamento.

Abstract True splenic artery aneurysms (SAA) are a rare, but potentially fatal, pathology. They are the third most common type of abdominal aneurysm, after aneurysms of the aorta and of the iliac artery, and account for almost the all aneurysms of visceral arteries. True aneurysms account for 60% of SAA and affect four times as many women as men, generally related to increased incidental or symptomatic findings that coincide with use of ultrasonography in pregnancy. Among pregnant patients, mortality after rupture is 65-75%, with fetal mortality exceeding 90%. There are multiple etiologies and it is believed that hormonal influences and changes in portal flow during gestation play an important role in development of SAA. This review discusses their history, epidemiology, pathophysiology, and diagnosis and current treatment techniques.

RESUMEN

Nos últimos anos, balões farmacológicos surgiram como promissora alternativa terapêutica em intervenções endovasculares. Com essa tecnologia, transferem-se drogas antiproliferativas à parede arterial, sem a necessidade de implante metálico para liberação. Descreve-se o caso de um paciente com uma segunda recidiva de reestenose intra-stent renal tratada por angioplastia com balão coberto por droga, com boa evolução clínica caracterizada por adequado controle pressórico e redução de classes e dosagem dos anti-hipertensivos. Os resultados obtidos com balões farmacológicos em outros territórios e esta experiência isolada podem contribuir como sugestão para o uso desses dispositivos na reestenose intra-stent renal, com resultados iniciais satisfatórios

During recent years, drug-coated balloons (DCBs) have emerged as a promising therapeutic option. DCBs directly transfer antiproliferative drugs to the arterial wall in order to decrease myointimal hyperplasia. We describe a case of de novo renal artery in-stent restenosis (ISR) treated with drug-coated balloon angioplasty with acceptable short-term results, achieving blood pressure control using fewer antihypertensive agents. The experience and results obtained with DCBs in other territories could suggest and justify use of this technology in renal artery ISR

RESUMEN

Importance: Reticular veins are subdermal veins located in the lower limbs and are mainly associated with aesthetic complaints. Although sclerotherapy is the treatment of choice for reticular veins in the lower limbs, no consensus has been reached regarding to the optimal sclerosant. Objective: To compare the efficacy and safety of 2 sclerosants used to treat reticular veins: 0.2% polidocanol diluted in 70% hypertonic glucose (HG) (group 1) vs 75% HG alone (group 2). Design, Setting, and Participants: Prospective, randomized, triple-blind, controlled, parallel-group clinical trial with patients randomly assigned in a 1:1 ratio between the 2 treatment groups from March through December 2014, with 2 months' follow-up. The study was conducted in a single academic medical center. Eligible participants were all women, aged 18 to 69 years, who had at least 1 reticular vein with a minimum length of 10 cm in 1 of their lower limbs. Interventions: The patients underwent sclerotherapy in a single intervention with either 0.2% polidocanol plus 70% HG or 75% HG alone to eliminate reticular veins. Main Outcomes and Measures: The primary efficacy end point was the disappearance of the reticular veins within 60 days after treatment with sclerotherapy. The reticular veins were measured on images obtained before treatment and after treatment using ImageJ software. Safety outcomes were analyzed immediately after treatment and 7 days and 60 days after treatment and included serious adverse events (eg, deep vein thrombosis and systemic complications) and minor adverse events (eg, pigmentation, edema, telangiectatic matting, and hematomas). Results: Ninety-three women completed the study, median (interquartile range) age 43.0 (24.0-61.0) years for group 1 and 41.0 (27.0-62.0) years for group 2. Sclerotherapy with 0.2% polidocanol plus 70% HG was significantly more effective than with 75% HG alone in eliminating reticular veins from the treated area (95.17% vs 85.40%; P < .001). No serious adverse events occurred in either group. Pigmentation was the most common minor adverse event, with a 3.53% treated-vein pigmentation length for group 1 and 7.09% for group 2, with no significant difference between the groups (P = .09). Conclusions and Relevance: Sclerotherapy with 0.2% polidocanol diluted in 70% HG was superior to 75% HG alone in sclerosing reticular veins, with no statistical difference for complications. Pigmentation occurred in both groups, with no statistical difference between them. No serious adverse events occurred in either group. Trial Registration: clinicaltrials.gov Identifier: NCT02054325.

RESUMEN

Resumo Infecções de sítios cirúrgicos com envolvimento de próteses sintéticas constituem grande desafio para tratamento. Apresentamos o caso de uma paciente com múltiplas comorbidades, histórico de enxerto aortobifemoral há 6 anos e reabordagem das anastomoses femorais por reestenoses há 5 anos. Apresentou dor inguinal esquerda e abaulamento súbitos com diagnóstico de pseudoaneurisma femoral roto e instabilidade hemodinâmica. Foi submetida a correção emergencial com interposição de prótese de dácron recoberta por prata e correção de grande hérnia incisional abdominal com tela sintética ao mesmo tempo. No pós-operatório, manteve-se por longo período sob terapia intensiva com dificuldade de extubação. Nesse ínterim, apresentou deiscência das suturas e fístula purulenta inguinal esquerda em contato com a prótese vascular. Optou-se pelo tratamento conservador, com desbridamento das feridas e aplicação de curativo a vácuo. A paciente evoluiu com melhora e cicatrização das feridas. Essa pode se constituir em ferramenta importante em casos similares.

Abstract Infections at the sites of surgery involving synthetic prostheses are challenging to treat. We present a case of a patient with multiple comorbidities who had undergone an aortobifemoral bypass 6 years previously and then re-intervention at the femoral anastomoses for restenosis 5 years previously. The patient presented with acute left inguinal pain and swelling and was diagnosed with a ruptured femoral pseudoaneurysm and hemodynamic instability. A repair was conducted by interposition of a silver-coated Dacron graft in the emergency room, and a large abdominal incisional hernia was repaired with synthetic mesh during the same intervention. After surgery, the patient remained intubated in intensive care for a long period. Meanwhile, she presented dehiscence of sutures and a left inguinal purulent fistula that was in contact with the vascular prosthesis. Conservative treatment was chosen, with debridement of wounds and vacuum therapy. The patient improved and the wounds healed. This could be an important tool in similar cases.

RESUMEN

BACKGROUND: Telangiectasias are defined as small venules abnormally dilated, located in the intradermal portion of the skin, of reddish or bluish tinge, their diameter not exceeding 1 mm; they are classified by the American Venous Forum as mild venous disease CEAP C1. Conventional treatment consists of chemical sclerotherapy, considered a minimally invasive technique with rapid clinical recovery. A wide variety of sclerosing solutions can be used for this purpose. METHODS/DESIGN: This project intends to include 96 patients that will be randomized to a triple-blind study. Inclusion criteria are women between 18 and 65 years, with telangiectasia on the lateral thigh. Male patients, female patients with chronic venous disease CEAP 2 to 6, women with allergies, pregnant, breastfeeding, with any type of skin problems or any decompensated clinical disease will be excluded. All patients included will be submitted to venous ultrasound mapping in order to rule out venous disease not clinically visible, deep venous system insufficiency, and insufficiency of the ostial valve of the great saphenous vein. One group will be treated with glucose 75% solution and the other will receive polidocanol 0.2% diluted in glucose 70%. Each patient will receive only 1 treatment session in 1 single member. The volume of sclerosing solution will not exceed 5 mL and the treatment area will be limited to a region of 150 cm on the lateral thigh. Clinical follow-up will be: 1 initial visit, when the clinical report will be filled; photographic record and treatment with sclerotherapy (D0); follow-up visits after 7 and 60 days (D7 and D60, respectively), always with clinical and photographic documentation. DISCUSSION: The project intends to evaluate the efficacy and safety of sclerotherapy in eliminating telangiectasia in a predetermined area in order to establish efficacy and safety parameters for the treatments presented. CONCLUSION: This protocol for clinical trial will provide date to determine the efficacy and safety of sclerotherapy with the solutions presented. TRIAL REGISTRATION IDENTIFIER: ClinicalTrial.gov NCT02657252 Date: 01/12/2016 (retrospectively registered).
