ABSTRACT

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.


Abstract 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.

ABSTRACT

A claudicação intermitente está frequentemente associada à doença aterosclerótica, mas diagnósticos diferenciais devem ser pesquisados em pacientes sem fatores de risco tradicionais. A doença cística adventicial, de etiologia incerta, acomete em maior proporção a artéria poplítea e, eventualmente, apresenta-se como claudicação intermitente. Apresentamos um caso da doença e seu manejo cirúrgico, e discutimos a etiopatogenia, os aspectos diagnósticos e terapêuticos da enfermidade.


Intermittent claudication is frequently associated with atherosclerotic disease, but differential diagnosis must be sought in patients with no traditional risk factors. Cystic adventitial disease, of unknown etiology, most frequently affects the popliteal artery, and occasionally presents as intermittent claudication. We report a case of this disease and the surgical treatment, and discuss some aspects related to etiopathogenesis, diagnosis and treatment of this condition.

ABSTRACT

OBJECTIVE: To present our experience with subintimal angioplasty (SA) for treatment of chronic lower limb ischemia (CLLI) and to assess its effectiveness and durability. MATERIALS AND METHODS: From April 2003 through June 2005, we treated 40 limbs in 36 patients with CLLI by SA. Balloons with or without secondary stent placement appropriate in size to the occluded arteries were used for SA of all lesions, except for iliac lesions where primary stent placement was done. The patients were followed for 1-23 months by clinical examination and color Doppler ultrasound and/or CT angiography. Technical results and outcomes were retrospectively evaluated. The presence of a steep learning curve for performance of SA was also evaluated. Primary and secondary patencies were determined using Kaplan-Meier analysis. RESULTS: Technical success was achieved in 32 (80%) of 40 limbs. There was no statistical difference between technical success rates of 75% (18/24) during the first year and 88% (14/16) thereafter. There were four complications (10%) in 40 procedures; two arterial perforations, one pseudoaneurysm at the puncture site, and one delayed hematoma at the SA site. Excluding initial technical failures, the primary patency rates at six and 12 months were 68% and 55%, respectively. Secondary patency rates at six and 12 months were 73% and 59%, respectively. CONCLUSION: Subintimal angioplasty can be accomplished with a high technical success rate. It should be attempted in patients with CLLI as an alternative to more extended surgery, or when surgical treatment is not recommended due to comorbidity or an unfavorable disease pattern.

ABSTRACT

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).CONCLUSAO: 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.

ABSTRACT

OBJETIVO: Estudar prospectivamente os resultados obtidos com o tratamento cirúrgico de portadores de claudicação intermitente que não obtiveram melhora clínica com o tratamento conservador, acompanhados, em média, por 6 anos. MÉTODOS: De janeiro/1992 a janeiro/2002 foram acompanhados 26 pacientes tratados cirurgicamente de um grupo de 1380 portadores de claudicação intermitente, admitidos num ambulatório de doença arterial obstrutiva periférica e claudicação intermitente, representando 1,88 por cento do total. RESULTADOS: Não referiam limitação para deambular após a cirurgia 16 pacientes. Experimentaram melhora nove, porém com algum grau de limitação, e dois, pequena melhora na distância máxima de marcha. Não houve mortalidade intra-operatória. Três pacientes apresentaram trombose da artéria tratada 6,48 e 60 meses após o procedimento e passaram a apresentar claudicação intermitente para as distâncias prévias à cirurgia. Durante o seguimento a longo prazo observamos uma mortalidade de 23,0 por cento devido a infarto agudo do miocárdio (4 casos), insuficiência renal (um) e acidente vascular cerebral (um). Dois pacientes foram submetidos a revascularização do miocárdio 2 e 4 anos após a reconstrução arterial e um ainda necessitou angioplastia coronariana com 3 anos de seguimento. O tempo de seguimento médio foi de 73 meses. CONCLUSAO: O tratamento cirúrgico diminuiu sintomas isquêmicos da claudicação intermitente em muitos pacientes, com excelente taxa de patência (88,4 por cento) dos enxertos, tornando-se em pacientes que não apresentam melhora com tratamento clínico, boa alternativa com baixas taxas de complicações e bons resultados a longo prazo.

ABSTRACT

Buerger's disease is a limb-threatening condition occurring in the young and productive age group and its management has always been a challenging problem. A large number of medical and surgical options have been suggested, but the quest for an ideal solution to this problem continues. Omentopexy for Buerger's disease is an attractive option, which is rapidly gaining popularity. We discuss the historical aspects, technical considerations and results of omental transfer for this limb-threatening condition. In doing so, the relevant literature on the subject has been extensively reviewed. In all published series, there has been marked improvement in intermittent claudication and rest pain. Ischaemic ulcers have healed and the progression of gangrene has stopped. If carried out with the complete understanding of the anatomy of the omental vascular arcade, the results of omentopexy are gratifying, thus avoiding amputation and conserving the limb.

ABSTRACT

CONTEXT: Many patients with intermittent claudication continue to be forwarded to the vascular surgeon for initial evaluation after arteriography has already been accomplished. OBJECTIVE: The main objective of this work was to analyze the usefulness and the need for this procedure. TYPE OF STUDY: Retrospective study. SETTING: The patients were divided into two groups: Group 1, with the arteriography already performed and Group 2 without the initial arteriography. PARTICIPANTS: One hundred patients with intermittent claudication were retrospectively studied. Other specialists had forwarded them for the first evaluation of intermittent claudication, without any previous treatment. MAIN MEASUREMENTS: All patients were treated clinically for at least a 6-month period. The total number of arteriographies performed in the two groups was compared and the need and usefulness of the initial arteriography (of Group 1) was also analyzed. RESULTS: The evolution was similar for both groups. The total number of arteriographies was significantly higher in Group 1 (Group 1 with 53 arteriographies vs. Group 2 with 7 arteriographies). For this group, it was found that arteriography was only useful in five cases (10 percent), because the surgeries were based on their findings. However, even in those cases, no need for arteriography was observed, as the procedure could have been performed at the time of surgical indication. CONCLUSION: There are no indications for arteriography in the early evaluation of patients with intermittent claudication, because it does not modify the initial therapy, independent of its result. In cases where surgical treatment is indicated, this procedure should only be performed prior to surgery

ABSTRACT

Objetivo: Reportar la experiencia en la derivación a la arteria peronea con vena safena reversa. Antecedentes: Frecuentemente la arteria peronea es el único vaso tibial permeable, especialmente en pacientes diabéticos quienes presentan una enfermedad oclusiva avanzada. Material y métodos: Durante un periodo de 9 años, más de 142 derivaciones arteriales fueron realizadas para salvamento de extremidades en nuestro hospital. Catorce pacientes fueron revascularizados por isquemia crítica. Las indicaciones quirúrgicas fueron; dolor de reposo 12 (85 por ciento), úlceras isquémicas 10 (71 por ciento), gangrena 6 (42 por ciento). La edad promedio fue de 68 años, 8 hombres y 6 mujeres. Los factores de riesgo fueron: diabetes mellitus 10, hipertensión 12, historia de enfermedad coronaria 6, tabaquismo 14. Previo a la revascularización todos los pacientes tuvieron en riesgo de perder la extremidad. El acceso quirúrgico fue abordaje lateral fibulectomía 5, abordaje lateral sin fibulectomía 6, vía medial posterior 3. Todas las anastomosis proximales fueron de la arteria poplítea. Resultados: Tres pacientes requirieron amputación mayor dentro de los 30 días después de revascularizados. Ellos tuvieron una arteria peronea con longitud menor de 10 cm, diámetro menor de 2 mm, escasa o ausente circulación colateral demostrada arteriográficamente. Salvamento de extremidad 78 por ciento a un año, sin mortalidad operatoria. Permeabilidad a 3 años del 57 por ciento, tres muertes tardías debidas a infarto del miocardio. Conclusiones: La revascularización de la arteria peronea es una alternativa para evitar una amputación mayor. El abordaje quirúrgico no altera la permeabilidad.

ABSTRACT

Antecedentes: Se destaca la particular importancia de estas lesiones que pueden ocasionar la pérdida del miembro. Objetivo: Se hace un estudio retrospectivo de los casos operados por patología de la arteria poplítea. En el mismo se incluyen la patología obliterante por arteriosclerosis, los aneurismas poplíteos, las embolias, los traumatismos y las enfermedades poco frecuentes. Material: Se efectuaron 435 operaciones por patología obliterante arterioesclerótica. Método: De preferencia se utilizó el autoinjerto venoso y los resultados fueron favorables en el 83,2 por ciento de los casos. Se operaron 52 aneurismas poplíteos, el 50 por ciento asintomáticos y los restantes con isquemia aguda o hemorragia. Resultados: Fueron buenos en el 96,1 por ciento de los casos. se destaca la importancia de operar estos aneurismas aún asintomáticos por el alto porcentaje de complicaciones que pueden presentar, especialmente trombosis. Se operaron 66 embolias de la arteria poplítea. La principal fuente embolígena fue el corazón con fibrilación auricular. En este grupo de pacientes hubo un porcentaje alto de amputaciones, 19,6 y 6 por ciento de mortalidad. En los 19 casos de traumatismo de arteria poplítea operados hubo un 10,5 por ciento de amputaciones. Se resalta la importancia del diagnóstico temprano, especialmente en los traumatismos cerrados. Entre las enfermedades poco frecuentes se presentan 2 aneurismas infecciosos, 1 aneurisma arteriovenoso, 2 casos de enfermedad adventicial quística y 2 de síndrome de atrapamiento. Estas infecciones deben sospecharse en pacientes jóvenes por debajo de la edad habitual para la arterioesclerosis. Conclusión: Se hace una revisión diagnóstica, terapéutica y de los resultados de 579 casos operados por distintas patologías de la arteria poplítea

ABSTRACT

Chronic occlusive arterial diseases form a single largest entity amongst the peripheral vascular diseases. Current operative methods available for improving circulation often elicit poor results and the patient has to undergo an amputation. The technique of pedicled omental transfer has given hope of saving such unsalvageable limbs. Although symptomatic and clinical improvement has been reported by this method of "biological by-pass revascularisation", there are no simple, objective and easily reproducible tests to assess improvement in circulation. In this study pulse oximetry and stress testing have been used to assess revascularisation. This study comprised 56 patients (78 limbs) suffering from chronic occlusive arterial disease, spanning a period of 5 years. Patients were investigated and subjected to pedicled omental transplantation (omentopexy). Symptomatological assessment showed improvement in intermittent claudication in about 85% of patients, relief from rest pain in 86% and healing of chronic ulcers in 73% of patients. Objective tests of stress testing and pulse oximetry also showed improvement in circulation. Relief from ischaemia was more in cases of Buerger's disease (TAO) than in cases of atherosclerosis obliterans (ASO).

ABSTRACT

23 cases of spondylolisthesis of the lumbo sacral spine are reported. One case is recurrent after previous operation elsewhere. Dysplastic, ischemic and degenerative spondylolisthesis are the main types of this disorder of the lumbosacral spine. Plain x-ray with dynamic films in the erect position are the gold standard for investigating these cases. Loss of parallelism of surfaces of vertebrae at the olisthesis level indicate pathological motion. Conservative treatment should be tried in every case. The decision for surgical treatment is clinical and rests absolutely on the evaluation of the surgeon of the pain syndrome of the patient and other complaints. The author uses a good quality acrylic to fix the whole lumbosacral spine with short screws inserted in the spines of the lumbar vertebrae. Only laminectomy and medial partial facetectomy are required in cases of neurogenic claudication with stable fixed spondylolisthesis. The results of treatment of spondylolisthesis are far from being satisfactory to say the least. The development of pain control centers to treat low back pain and leg pains attest to the failure of the state of art today to manage this disorder on sound scientific basis. These centers specialize in the management of failed back surgery for this conditions and others of the spine. The cause of biological infirmity of the disc may be part of maldevelopment as in dysplastic type or it is inherent in its microstructure. All other pathological phenomena seen in this disorder are secondary effects

ABSTRACT

El objetivo de este trabajo es analizar las causas de recurrencia de enfermedad arterial aortoilíaca en pacientes sometidos a cirugía previa de revascularización y también mostrar el manejo que hemos hecho a estos problemas. Se han realizado 45 operaciones en 32 pacientes que presentaron isquemia tardía o pseudoaneurisma en los últimos 8 años después de haber sido sometidos a cirugía arterial protésica. En el mismo lapso se realizaron 304 operaciones arteriales derivativas. Basados en la historia clínica, datos operatorios y angiografías se encontró que en 31 oportunidades había progresión de la enfermedad (68,8 por ciento ), en 10 había pseudoaneurismas (22,2 por ciento ), en 2 existían problemas derivados del injerto mismo (4,4 por ciento ) y 2 presentaron lesiones traumáticas (4,4 por ciento ). El tiempo promedio entre la primera operación y la siguiente fue de 32,5 meses. Se hicieron reconstrucciones aórticas mayores en 5 pacientes (11,1 por ciento ), procedimientos combinados (abdominales e inguinales) en 11 pacientes (24 por ciento ) por ciento y técnicas locales en región inguinal en 29 (64 por ciento ). La mortalidad global fue de tres pacientes (9 por ciento ) y fue necesaria la amputación en 8 casos (17,7 por ciento )
