Sustained Benefit Lasting One Year from T4 Instead of T3-T4 Sympathectomy for Isolated Axillary Hyperhidrosis

INTRODUCTION: Level T4 video-assisted thoracoscopic sympathectomy proved superior to T3-T4 treatment for controlling axillary hyperhidrosis at the initial and six-month follow-ups of these patients. OBJECTIVE: To compare the results of two levels of sympathectomy (T3-T4 vs. T4) for treating axillary sudoresis over one year of follow-up. METHODS: Sixty-four patients with axillary hyperhidrosis were randomized to denervation of T3-T4 or T4 alone and followed prospectively. All patients were examined preoperatively and were followed postoperatively for one year. Axillary hyperhidrosis treatment was evaluated, along with the presence, location, and severity of compensatory hyperhidrosis and self-reported quality of life. RESULTS: According to patient reports after one year, all cases of axillary hyperhidrosis were successfully treated by surgery. There were no instances of treatment failure. After six months, compensatory hyperhidrosis was present in 27 patients of the T3-T4 group (87.1%) and in 16 patients of the T4 group (48.5%). After one year, all T3-T4 patients experienced some degree of compensatory hyperhidrosis, compared to only 14 patients in the T4 group (42.4%). In addition, compensatory hyperhidrosis was less severe in the T4 patients (p < 0.01). Quality of life was poor before surgery, and it improved in both groups at six months and one year of follow-up (p = 0.002). There were no cases of mortality, no significant postoperative complications, and no need for conversion to thoracotomy in either group. CONCLUSION: Both techniques were effective for treating axillary hyperhidrosis, but the T4 group showed milder compensatory hyperhidrosis and greater patient satisfaction at the one-year follow-up

Tratamento endovascular para pacientes portadores de Claudicação Intermitente que não melhoram com tratamento clínico

PURPOSE: To study the results including long-term follow-up obtained with endovascular treatment of patients with intermittent claudication who did not experience clinical improvement with conservative treatment. METHODS: From January 1992 to January 2002, 62 of 1380 patients (4.5%) with intermittent claudication underwent endovascular treatment and were followed up for up to 120 months (mean 76 months). The variables analyzed were the functioning of the arterial segment undergoing the endovascular procedure, the evolution of the maximum walking distance, and incidence of related morbidity and mortality. RESULTS: Fifty-two patients (84%) experienced no walking limitation after the procedure, and 6 patients (10%) improved but still exhibited some degree of limitation, for a total improved outcome of 94%. The patency rate was 82%. There was no intraoperative mortality. One primary failure and one immediate thrombosis occurred, and both were surgically corrected. Thrombosis of the treated artery occurred in 6 patients 12, 16, 25, 29, 62, and 66 months after the procedure. These patients started to experience intermittent claudication with a walking distance to onset that was similar to their presurgical distance to onset. During follow-up, a mortality rate of 12.9% (8 patients) was observed, 6 due to myocardial infarctions and 2 due cerebral infarction. Three patients underwent coronary bypasses 22, 36, and 55 months after the endovascular surgery, and 2 patients underwent coronary angioplasty after 6 and 26 months. The mean follow up period was 76 months (range 0-120 months). CONCLUSION: This study shows that endovascular treatment of intermittent claudication brought about a lasting regression of the ischemic conditions in a significant number of patients, with excellent patency rates. It was concluded that this is a good alternative for selected patients, with low rates of complications and positive long-term results.OBJETIVO: Estudar a longo prazo (média de 76 meses de seguimento) os resultados obtidos com o tratamento endovascular em pacientes que não melhoram com o tratamento clínico, MÉTODOS: De Janeiro de 1992 a Janeiro de 2002, 62 pacientes de um grupo de 1380 claudicantes foram submetidos a tratamento endovascular, representando 4,5% do total. As variáveis analisadas foram o funcionamento do segmento arterial submetido ao procedimento endovascular, a evolução da distância máxima de marcha e a ocorrência de morbi-mortalidade. RESULTADOS: Cinqüenta e dois (84%) pacientes não apresentaram restrições à deambulação após o procedimento. Seis pacientes melhoraram, representando um benefício de 94%. Não houve mortalidade intra-operatória. Uma falência primária e uma trombose imediata foram corrigidas cirurgicamente. Seis pacientes apresentaram trombose da artéria tratada 12, 16, 25, 29, 62 e 66 meses após o procedimento e voltaram a apresentar Claudicação Intermitente para as mesmas distâncias referidas antes da cirurgia. Durante o seguimento foi observada taxa de mortalidade de 12,9% (8 pacientes), dos quais 6 por infarto do miocárdio e dois por acidente vascular cerebral. Três pacientes foram submetidos à revascularização miocárdica 22, 36 e 55 meses após o procedimento endovascular e duas angioplastias foram realizadas com 6 e 26 meses de seguimento. O tempo médio de segmento foi de 76 meses (0 a 120 meses). CONCLUSÃO: O tratamento endovascular da Claudicação Intermitente levou a melhora das condições da marcha em um número significativo de pacientes, com excelentes taxas de patência (82,0%). Concluímos que esta é uma boa alternativa para determinados pacientes, com poucas complicações e resultados positivos a longo prazo

Agressão externa aos membros inferiores como fator preditivo na evolução dos pacientes submetidos a revascularização arterial

PURPOSE: A variety of predictive factors for the evolution of arterial grafts in patients with critical ischemia have been well defined in clinical studies, including diabetes mellitus, dialytic renal insufficiency, smoking, and distal arterial runoff. The goal of this study was to determine whether patients with critical ischemia undergoing arterial reconstruction in which ischemic lesions appeared spontaneously, compared to those in which the ischemic lesion appeared following an external aggression to the limb present different patterns of evolution. METHODS: From February 2002 to January 2004, 100 patients undergoing infra-inguinal arterial reconstruction were followed. They were divided into 2 groups: 1) the spontaneous group (n = 52), comprising individuals presenting with ischemic lesions of spontaneous origin and 2) the external aggression to the limb group (n = 48), comprising individuals for which an external causal mechanism for the appearance of the ischemic lesion was identified. The variables analyzed were limb salvage and graft functioning rates. RESULTS: Patients with spontaneous lesions had rates of limb salvage and graft functioning significantly lower than those for patients with lesions that were secondary to external aggression (42.3% versus 87.5%, respectively for both outcomes; POBJETIVO: Diversos fatores preditivos de evolução de enxertos arteriais em pacientes com isquemia grave foram definidos em estudos clínicos como diabetes mellitus, insuficiência renal, fumo e vasão distal. O objetivo deste estudo foi verificar se pacientes com isquemia grave submetidos a revascularização nos quais as lesões apareceram espontaneamente apresentam evolução diferente daquela em que as lesões apareceram após uma agressão externa ao membro. MÉTODOS: De fevereiro de 2002 a janeiro de 2004, 100 pacientes submetidos a revascularizações infra-inguinais foram seguidos. Eles foram divididos em 2 grupos: 1) Grupo com lesão espontânea (52 pacientes), que compreendia pacientes apresentando lesões isquêmicas de origem espontânea e 2) Grupo de lesão por agressão externa (48 pacientes) que compreendia pacientes em que um mecanismo externo era identificado como causa do aparecimento da lesão isquêmica. As variáveis analisadas foram salvamento de membro e índices de perviedade dos enxertos. RESULTADOS: Pacientes com lesão espontânea apresentam índices de salvamento de membro e perviedade do enxerto significativamente menores que pacientes com lesões secundárias a agressão externa (42,3% x 87,5%, respectivamente para ambos itens de estudo;

Is Gender a Predictive Factor for Satisfaction among Patients Undergoing Sympathectomy to Treat Palmar Hyperhidrosis?

Video-assisted thoracic sympathectomy (VATS) is currently the procedure of choise for the definitive treatment of primary hyperhidrosis because it is an effective, safe, and minimally invasive method. The aim of VATS treatment is to improve the quality of life through the reduction of excessive sudoresis. The purpose of this study was to assess the quality of life after VATS for treating palmar hyperhidrosis according to gender

Randomized trial of radiofrequency ablation versus conventional surgery for superficial venous insufficiency: if you don’t tell, they won’t know

OBJECTIVES: This study compared radiofrequency ablation versus conventional surgery in patients who had not undergone previous treatment for bilateral great saphenous vein insufficiency, with each patient serving as his own control. METHOD: This was a randomized controlled trial that included 18 patients and was carried out between November 2013 and May 2015. Each of the lower limbs of each patient was randomly assigned to undergo either radiofrequency ablation or conventional surgery. Clinical features (hyperpigmentation, hematoma, aesthetics, pain, skin burn, nerve injury, and thrombophlebitis) were evaluated at one week, one month, and six months postoperatively. Hemodynamic assessments (presence of resection or occlusion of the great saphenous vein and recurrent reflux in the sapheno-femoral junction and in the great saphenous vein) were performed at one month, six months, and 12 months postoperatively. The independent observer (a physician not involved in the original operation), patient, and duplex ultrasonographer were not made aware of the treatment done in each case. Clinicaltrials.gov: NCT02588911. RESULTS: Among the clinical variables analyzed, only the aesthetic evaluation by the physicians was significant, with radiofrequency ablation being considered better than conventional surgery (average, 0.91 points higher: standard deviation: 0.31; 95% confidence interval: -1.51, -0.30; p=0.003). However, in our study, we observed primary success rates of 80% for radiofrequency ablation and 100% for conventional surgery. CONCLUSIONS: If the physician is not required to inform the patient as to the technique being performed, the patient will not be able to identify the technique based on the signs and symptoms. Our study revealed that both techniques led to high levels of patient satisfaction, but our results favor the choice of conventional surgery over radiofrequency ablation, as patients who underwent conventional surgery had better hemodynamic assessments

Impact of opioid-free analgesia on pain severity and patient satisfaction after discharge from surgery: multispecialty, prospective cohort study in 25 countries

Background: Balancing opioid stewardship and the need for adequate analgesia following discharge after surgery is challenging. This study aimed to compare the outcomes for patients discharged with opioid versus opioid-free analgesia after common surgical procedures.Methods: This international, multicentre, prospective cohort study collected data from patients undergoing common acute and elective general surgical, urological, gynaecological, and orthopaedic procedures. The primary outcomes were patient-reported time in severe pain measured on a numerical analogue scale from 0 to 100% and patient-reported satisfaction with pain relief during the first week following discharge. Data were collected by in-hospital chart review and patient telephone interview 1 week after discharge.Results: The study recruited 4273 patients from 144 centres in 25 countries; 1311 patients (30.7%) were prescribed opioid analgesia at discharge. Patients reported being in severe pain for 10 (i.q.r. 1-30)% of the first week after discharge and rated satisfaction with analgesia as 90 (i.q.r. 80-100) of 100. After adjustment for confounders, opioid analgesia on discharge was independently associated with increased pain severity (risk ratio 1.52, 95% c.i. 1.31 to 1.76; P &lt; 0.001) and re-presentation to healthcare providers owing to side-effects of medication (OR 2.38, 95% c.i. 1.36 to 4.17; P = 0.004), but not with satisfaction with analgesia (beta coefficient 0.92, 95% c.i. -1.52 to 3.36; P = 0.468) compared with opioid-free analgesia. Although opioid prescribing varied greatly between high-income and low- and middle-income countries, patient-reported outcomes did not.Conclusion: Opioid analgesia prescription on surgical discharge is associated with a higher risk of re-presentation owing to side-effects of medication and increased patient-reported pain, but not with changes in patient-reported satisfaction. Opioid-free discharge analgesia should be adopted routinely

Comparison of results obtained in the treatment of axillary hyperhidrosis using video-assisted thoracic sympathectomy at denervation levels T3-T4 versus T4

INTRODUÇÃO: O nível ótimo de simpatectomia para a hiperidrose axilar seria aquele que resultasse no tratamento definitivo da hiperidrose, associado à mínima intensidade de hiperidrose compensatória. OBJETIVO: Comparar duas técnicas cirúrgicas (níveis de desnervação) de simpatectomia por videotoracoscopia para o tratamento da hiperidrose axilar em um período de 12 meses. MÉTODO: De janeiro de 2004 a julho de 2007, foram seguidos 64 pacientes portadores de hiperidrose axilar randomizados para a simpatectomia por videotoracoscopia nos níveis dos gânglios T3-T4 ou T4. O acompanhamento ocorreu pelo período de 12 meses avaliando-se: a resolução da hiperidrose axilar; a incidência e intensidade da hiperidrose compensatória; sua evolução durante o estudo; e a qualidade de vida dos pacientes. RESULTADOS: Todos os pacientes apresentaram resolução da hiperidrose axilar. Não houve falhas terapêuticas. Após 12 meses, 57,6% dos pacientes do grupo T4 e 6,5% dos pacientes de T3-T4 apresentavam-se sem hiperidrose compensatória (p<0,001). Os pacientes do grupo T4 que apresentaram hiperidrose compensatória mostraram menor intensidade que os do grupo T3-T4, não sendo observada HC intensa (p<0,001). Verificou-se melhora da qualidade de vida desde a primeira avaliação, sendo que no grupo T4 esta se mostrou maior que no grupo T3-T4 a partir de seis meses de seguimento (p=0,002). CONCLUSÕES: Ambas as técnicas são efetivas para tratar a hiperidrose axilar. A complicação mais frequente foi a hiperidrose compensatória, que, cronologicamente, apresentou-se estável durante o estudo. A simpatectomia no nível T4 apresentou menor intensidade de HC, com melhora da qualidade de vida ao longo do seguimento.INTRODUCTION: The optimum level of sympathectomy for axillary hyperhidrosis is one that would result in a definitive treatment of hyperhidrosis, associated with a lower severity of compensatory hyperhidrosis. OBJECTIVE: To compare two surgical techniques (denervation levels) of sympathectomy with video-assisted thoracic sympathectomy to treat axillary hyperhidrosis in a period of 12 months. METHODS: From January 2004 to July 2007, 64 patients with axillary hyperhidrosis were randomized for videoassisted thoracic sympathectomy at the T3-T4 or T4 ganglia level; they were followed up for a 12-month period in order to evaluate axillary hyperhidrosis, the incidence and severity of compensatory hyperhidrosis, its evolution throughout the study, and the patients\' quality of life. RESULTS: Sixty four patients presented resolution of the axillary hyperhidrosis. No therapeutic failures occurred. After 12 months, 57.6% of the patients of the T4 group and 6. 5% of the T3-T4 group had not developed compensatory hyperhidrosis (p<0.001). Patients of the T4 group who experienced compensatory hyperhidrosis presented a rate lower than those in the T3-T4 group, and no severe CH (p<0.001) was observed. Improvement in the quality of life was reported since the first evaluation, proving to be higher in the T4 group than in the T3-T4 group, starting after six months of follow-up (p=0.002). CONCLUSIONS: Both techniques are effective for treating axillary hyperhidrosis. The most frequent complication was compensatory hyperhidrosis, which remained chronologically stable throughout the study. The T4-level sympathectomy group presented a less severe compensatory hyperhidrosis

Comparison of Laser Versus Sclerotherapy in the Treatment of Lower Extremity Telangiectases: A Prospective Study

BACKGROUND Lower extremity telangiectasia affects approximately 40% of women. The demand for aesthetic treatment of these veins continues to grow. Few studies have compared laser and sclerotherapy to treat leg telangiectasias. OBJECTIVE To compare the efficacy of conventional sclerotherapy and neodymium-doped yttrium aluminum garnet (Nd:YAG) laser in the treatment of leg telangiectasias. METHODS AND MATERIALS Thirty women were enrolled in the study. One leg was randomly assigned laser treatment and the other sclerotherapy with 75% glucose solution. All patients were photographed before and after treatment. The applying physician and two independent observers rated photographic improvement of the treated areas. Complications and adverse effects were noted during follow-up. Patients answered a questionnaire that addressed pain, clearing of the vessels, and satisfaction with the results. RESULTS There was a significant difference between the modes of treatment regarding pain. Twelve patients using laser and 16 using sclerotherapy considered the clearing of the vessels to be good to excellent after three sessions of both laser and scleratherapy. Mean scores after photographic assessment were 7.9 for laser and 7.0 for sclerotherapy. CONCLUSION Lower extremity telangiectases may be treated equally well using Nd:YAG 1064-nm laser or conventional sclerotherapy
