RESUMEN
INTRODUCTION: Transdermal laser is an option for varicous veins treatment, yet it may be painful. In this study, we will present a technique for performing tumescent anesthesia associated to transdermal laser (TTL) to reduce pain during treatment. OBJECTIVE: The study compares pain during treatment of telangiectasias in lower limb with and without tumescent anesthesia to offer a less painful procedure. METHODS: 50 CEAP C1 patients with bilateral telangiectasias on thighs underwent transdermal laser treatment, using tumescent anesthesia on one side and standard technique on the other. Pain was assessed via the Visual Analogue Scale. The outcomes were compared with Student's t-test. Significance was set at p < .05. RESULTS: Laser treatment without tumescent anesthesia resulted in a VAS pain score of 7.9, versus 0.0 with anesthesia, showing a significant statistical difference. CONCLUSION: Tumescent anesthesia and transdermal laser (TTL) is capable of reducing pain in laser treatment of telangiectasias and reticular veins.
RESUMEN
Background: Central venous catheters are essential for management of hospitalized patients, but their insertion is subject to complications that can make them unusable and/or cause patient morbidity. There are few data on the incidence of these complications and the variables associated with these outcomes in Brazil. Objectives: To determine the incidence of mechanical complications and failures of short stay central venous catheters fitted by the vascular surgery service at a teaching hospital and identify variables associated with their occurrence. Methods: This was a prospective cohort of 73 attempts to fit patients with a central venous catheter performed by the vascular surgery service at a teaching hospital from July to October of 2022. Results: Mechanical complications occurred in 12 cannulation attempts (16.44%) and there were 10 failures (13.70%). The factors associated with mechanical complications were less experienced operators (p < 0.001), less specialized operators (p = 0.014), a failed attempt prior to requesting help from the vascular surgery service (p = 0.008), and presence of at least two criteria for difficulty (p = 0.007). Conclusions: The local incidence of mechanical complications and central venous cannulation failures was similar to rates described in the international literature, but higher than rates in other Brazilian studies. The results suggest that the degree of experience of the person fitting the catheter, history of a failed prior attempt, and presence of at least two criteria for difficulty identified before the procedure were associated with worse outcomes.
RESUMEN
Resumo Contexto Os acessos venosos centrais são essenciais no manejo de pacientes hospitalizados; contudo, a sua inserção está sujeita a complicações que podem dificultar seu uso e causar morbidade aos pacientes. No Brasil, dados acerca da incidência dessas complicações e das variáveis associadas com esse desfecho são escassos. Objetivos Determinar a incidência de complicações mecânicas e de falhas de acessos venosos centrais de curta permanência realizados no serviço de Cirurgia Vascular de um hospital de ensino, além de identificar as variáveis associadas com a sua ocorrência. Métodos Tratou-se de uma coorte prospectiva com 73 tentativas de acesso venoso central realizadas em pacientes assistidos pelo serviço de Cirurgia Vascular de um hospital de ensino entre julho e outubro de 2022. Resultados Complicações mecânicas ocorreram em 12 tentativas de acessos (16,44%), e falhas, em 10 tentativas (13,70%). Os fatores associados às complicações mecânicas foram menor experiência do operador (p < 0,001), menor grau de especialização do operador (p = 0,014), falha na tentativa de acesso precedente à solicitação de auxílio ao serviço de Cirurgia Vascular (p = 0,008) e presença de pelo menos dois critérios de dificuldade (p = 0,007). Conclusões A incidência local de complicações mecânicas e de falhas dos acessos venosos centrais foi semelhante à descrita na literatura internacional, mas foi superior à descrita em trabalhos brasileiros. Os resultados sugerem que o grau de experiência do executor do acesso, a história de falha em tentativa precedente e a presença de pelo menos dois critérios de dificuldade verificados antes do procedimento estão associados com piores desfechos.

RESUMEN
PURPOSE: To present the preliminary results of a cohort of 13 patients with hip osteoarthritis (OA) and great trochanteric pain syndrome (GTPS) refractory to conservative management or physical therapy and no indication for surgery treated with embolization of the lateral femoral circumflex artery. MATERIAL AND METHODS: This is a single-center prospective cohort from July 2019 to September 2020. Visual analogue scale (VAS) and Western Ontario and MacMaster Universities (WOMAC) were used to compare the symptoms before and after 6-month follow-up. Technical success was considered when at least one artery responsible for the hyperemic synovium was embolized. Complications and adverse events were noted. RESULTS: In total, 13 patients were included; mean age was 62.4 (± 11.0) years. 10 (76.9%) patients were treated for GTPS and 3 (23.1%) for hip OA. Nine patients were treated with imipenem/cilastatin (I/C) alone. Microsphere 100-300 µm and I/C were combined in 4 patients. The WOMAC Index had a statistically significant decrease in the total from 77 to 27 points (p = 0.001). Pain, rigidity and physical activity have also significantly reduced (19 to 5, p = 0.001; 6 to 2, p = 0.002 and 53 to 22, p = 0.001, respectively). VAS score had a significant decrease (10 to 2, p = 0.002). Two patients present posterior tight numbness, spontaneously improved within 30 days. CONCLUSION: In this cohort, lateral femoral circumflex artery embolization was a safe and effective treatment for patients with hip pain due to OA and GTPS.

Coarctation of the abdominal aorta is a rare etiology of intermittent claudication and refractory hypertension. Treatment is complex and requires knowledge of several vascular reconstruction techniques. We report a case of aortic coarctation at the level of the renal arteries, describing its treatment and presenting a literature review. Female patient, 65 years old, with refractory hypertension since the age of 35, using five antihypertensive medications at maximum doses. Blood pressure was 260/180mmHg and she had disabling claudication (less than 20 meters). Computed tomography angiography showed a 4mm coarctation in the juxtarenal aorta, with circumferential calcification at the stenosis site, and tortuous infrarenal aorta. Hybrid repair was performed with an iliac-birenal bypass and implantation of an Advanta V12 stent at the stenosis site. The patient's postoperative course was satisfactory, she was free from claudication, and her blood pressure 60 days after surgery was 140/80mmHg, taking two antihypertensive medications.
RESUMEN
Resumo Coarctação da aorta abdominal é uma causa rara de claudicação de membros inferiores e hipertensão refratária. O tratamento é complexo e exige conhecimento de diversas técnicas de reconstrução vascular. Apresentamos um caso de coarctação ao nível das artérias renais, seu tratamento e revisão da literatura. Paciente feminina, 65 anos, com hipertensão refratária desde os 35 anos, utilizando cinco medicações anti-hipertensivas em dose máxima. Pressão arterial média de 260/180mmHg e claudicação incapacitante (menos de 20 metros) bilateral. Angiotomografia computadorizada demonstrou coarctação de aorta justarrenal de 4 mm de maior diâmetro, calcificação circunferencial no local da estenose e tortuosidade da aorta infrarrenal. Foi submetida a tratamento híbrido, com ponte ilíaco-birrenal e implante de stent Advanta V12 no local da estenose. A paciente evoluiu satisfatoriamente e, 60 dias depois da cirurgia, apresentava-se com uma pressão arterial de 140/80mmHg, em uso de apenas duas medicações anti-hipertensivas e sem claudicação.

BACKGROUND: Osteoarthritis (OA) is the most frequent joint disease, affecting 10% of men and 18% of women older than 60 years worldwide. Traditionally, treatment is based in pain management with joint replacement of end-stage disease. In this setting, transcatheter embolization has emerged as an alternative in reduction of pain in patients with OA. CASE PRESENTATION: A 77 years-old female presenting with two previous deep vein thrombosis and 10 years of hip pain. Magnetic resonance demonstrated a focal area of enhanced pericapsular signal near the superolateral margin of the acetabulum. Embolization of branches of the ascending branch of the lateral femoral circumflex artery was performed, with decrease of the pain and improvement in the image and her walking ability in a four-month follow-up. CONCLUSION: This case report have shown that embolization of hip synovitis is feasible with early clinical success, in tune with the findings of genicular and shoulder embolization. Studies with more patients and long-term results are necessary to corroborate this finding. LEVEL OF EVIDENCE: 4.
