ABSTRACT

Introdução: Por muitos anos houve falta de médicos em muitas cidades do Brasil. Porém, a política nacional para a abertura de faculdades de medicina vem se caracterizando por um crescente e excessivo número de vagas ofertadas nos últimos anos. O objetivo deste estudo foi avaliar os dados sobre a criação de novas faculdades de medicina nos três estados da região sul do Brasil, analisando os em relação ao número de matrículas disponibilizadas e o número de médicos formados nos três estados que compõem a região. Métodos: Os diretores das faculdades de medicina nos três estados da região sul foram contatados para a obtenção dos dados sobre a criação de suas instituições. Realizou-se também a análise de dados referentes ao número de médicos formados e registrados nos conselhos regionais de medicina dos três estados no período de 1960 a 1999. Resultados: Houve um expressivo aumento no número de instituições criadas e vagas oferecidas ao longo dos anos em todos os estados analisados. No período de 1960 a 1999, o estado do Rio Grande do Sul já era autossuficiente em matrículas médicas, porém os estados de Santa Catarina e Paraná ainda apresentavam um número insuficiente de matrículas em cursos médicos. Conclusão: Apesar do número de médicos ter sido insuficiente durante alguns anos, os três estados analisados já apresentam um excessivo número de médicos formados. É necessário, portanto, analisar a relação entre o atual número comprovadamente excessivo de médicos e o quanto isto possa prejudicar a qualidade do atendimento ao paciente.


Introduction: For many years there was a shortage of physicians in many Brazilian cities. However, the national policy for the creation of medical colleges has been characterized by an excessive and increasing number of offered vacancies in recent years. The aim of this study was to evaluate the data for the creation of new medical schools in three southern states of Brazil, analyzing them in relation to the number of available registrations and the number of graduated doctors in the three states comprising the region. Methods: The directors of medical schools in three southern states were contacted to obtain data on the establishment of their institutions. We also analyzed the data on the number of graduated physicians registered in the regional medical councils of the three states from 1960 to 1999. Results: There was a significant increase in the number of created institutions and offered vacancies over the years in all three states analyzed. In the 1960-1999 period, the state of Rio Grande do Sul was self-sufficient in medical enrollments, but the states of Santa Catarina and Paraná still had an insufficient number of enrollments in medical courses. Conclusion: Although the number of physicians was insufficient for several years, today the three states already have an excessive number of medical graduates. It is therefore necessary to examine the relationship between the excessive number of physicians and how this might affect the quality of patient care.

ABSTRACT

The aim of this study was to compare the outcomes of emergent surgery caused by acute complications versus elective surgery of popliteal artery aneurysms (PAAs) and to evaluate the advantages of elective repair related to limb salvage and bypass patency rates. Fifty PAAs were operated on in 40 patients from January 2000 to December 2004. Surgery was elective in 34 cases (68%) and emergent in 16 (32%). Emergent repair was performed because of acute complications. All patients were treated surgically. Early results in terms of limb salvage, primary patency, and assisted patency were assessed. Follow-up consisted of clinical and/or ultrasonographic examinations at 10 days and 1, 3, 6, and 12 months and yearly thereafter. Long-term limb salvage and bypass patency rates were analyzed. The mean follow-up was 17 months. The 1-year limb salvage rate in the elective group was 97.1% versus 56.3% in the emergent group (P = .0007). The bypass patency rate at 1 year was 94.1% in the elective group versus 66.7% in the emergent group (P = .03). In this study, the outcomes of the PAA repair were significantly better in the group operated electively and without acute symptoms at presentation compared with the group with acute complications, operated on emergently, especially related to limb salvage and bypass patency rates.

ABSTRACT

Este estudo tem por objetivo relatar um caso de isquemia crítica de membro inferior associada a quimioterapia com gemcitabina. O relato descreve o caso de um paciente de 68 anos submetido a duodenopancreatectomia devido a tumor no pâncreas. Um mês depois da operação, o paciente realizou quatro sessões de quimioterapia com gemcitabina, durante um mês. Após 30 dias, o paciente desenvolveu sintomas de doença arterial obstrutiva periférica, e duas semanas depois, isquemia crítica do membro inferior direito. O exame por imagem demonstrou doença arterial difusa associada à oclusão femoropoplítea com reenchimento distal precário. O paciente foi submetido a uma tentativa de revascularização que, devido às condições locais, foi malsucedida, resultando na amputação do membro no nível da coxa.


We report a case of lower limb critical ischemia associated with chemotherapy with gemcitabine. This report presents a case of a 68-year-old man who underwent pancreatoduodenectomy due to pancreas tumor. One month later, the patient was submitted to four chemotherapy sessions with gemcitabine for 1 month. In addition, 30 days later he developed symptoms of peripheral arterial obstructive disease, and critical ischemia of the right lower limb 2 weeks later. An imaging study showed diffuse arterial disease associated with femoropopliteal occlusion and poor distal bed. The patient was submitted to a revascularization procedure, which was unsuccessful due to local conditions, resulting in above-knee amputation.

ABSTRACT

Objetivo: Avaliar os resultados cirúrgicos após o tratamento convencional e eletivo do aneurisma da aorta abdominal, verificando se existe diferença entre homens e mulheres na mortalidade e morbidade cirúrgicas, bem como nos resultados a longo prazo. Pacientes e métodos: Entre dezembro de 1983 e dezembro de 2003, 675 pacientes foram submetidos ao tratamento cirúrgico do aneurisma da aorta abdominal infra-renal, sendo divididos em dois grupos: homens (n igual 575) e mulheres (n igual 100). Os dados demográficos e aqueles relacionados ao procedimento cirúrgico, bem como os resultados perioperatórios, foram coletados pela revisão dos prontuários. Os pacientes com alta hospitalar formaram uma coorte retrospectiva, onde foram avaliadas as causas tardias de óbito e a sobrevida. Resultados: A média das idades foi similar, sem diferença estatística entre mulheres e homens (68,9 maior ou menor que 9,1 versus 67,4 maior ou menor que 7,1 anos; P igual 0,089)...

ABSTRACT

OBJECTIVE: To establish, in a case-control study, the early mortality and long-term survival after surgical correction of sealed rupture abdominal aortic aneurysm, compared to controls who underwent standard, nonruptured abdominal aortic aneurysm repair. PATIENTS AND METHODS: From January 1992 to December 2002, 465 patients underwent infrarenal abdominal aortic aneurysm repair. Of those, 13 had sealed rupture abdominal aortic aneurysm (2.8%). These cases were compared to 26 controlsin which surgical repair was performed immediately preceding or succeeding each one of the sealed rupture abdominal aortic aneurysm surgeries. RESULTS: Age, sex, risk factors for atherosclerosis, associated disease, and cardiac ischemia were similar between groups. Patients with sealed rupture abdominal aortic aneurysm presented a higher incidence of lumbar pain than controls (92.3% versus 3.9%; P < .001); fever and weight loss were detected in 5 (38.5%) patients with SAAA and in none of controls (P = .0022). Mean red blood cell transfusion was greater for sealed rupture abdominal aortic aneurysm than controls (1,516 +/- 697 vs. 773 +/- 463 mL (P = .0003). Postoperative complications were similar between groups. Early mortality was 7.7% for sealed rupture abdominal aortic aneurysm and 0% for controls. Five-year survival was significantly lower for sealed rupture abdominal aortic aneurysm (68.4%) than for controls (84.4%, P = .04). CONCLUSION: We conclude that sealed rupture abdominal aortic aneurysm presents diagnostic and surgical challenges that can be adequately managed, achieving early postoperative mortality and complication rates that are similar to standard abdominal aortic aneurysm. However, patients with sealed rupture abdominal aortic aneurysm present higher mortality in the long term compared with patients having standard abdominal aortic aneurysm.

ABSTRACT

OBJETIVO: Estabelecer, através de um estudo caso-controle, a mortalidade precoce e sobrevida a longo prazo após o tratamento cirúrgico do aneurisma da aorta abdominal roto contido crônico comparada aos respectivos controles, submetidos ao reparo do aneurisma da aorta abdominal não roto, operado eletivamente. PACIENTES E MÉTODO: De Janeiro de 1992 a Dezembro de 2002, 465 pacientes foram submetidos ao reparo de aneurismas da aorta abdominal. Destes, 13 eram aneurisma da aorta abdominal roto contido crônico (2,8%), que foram comparados a 26 controles nos quais a correção eletiva do aneurisma ocorreu imediatamente antes e após a correção do aneurisma da aorta abdominal roto contido crônico.RESULTADO: Não houve diferença entre os grupos com relação a idade, sexo, fatores de risco para aterosclerose, doenças associadas e cardiopatia isquêmica. Pacientes com aneurisma da aorta abdominal roto contido crônico apresentaram maior incidência de dor lombar (92,3% versus 3,9%; p<0,001); febre e perda ponderal foram detectados em cinco (38,5%) dos pacientes com aneurisma da aorta abdominal roto contido crônico e em nenhum dos controles (p=0,0022). A média de transfusão de hemácias também maior no aneurisma da aorta abdominal roto contido crônico (1516±697 vs. 773±463 ml (p=0,0003). As complicações pós-operatórias foram semelhantes entre os grupos. A mortalidade precoce foi de 7,7% nos pacientes com aneurisma da aorta abdominal roto contido crônico e 0% nos controles. A sobrevida em cinco anos foi significativamente menor nos portadores de aneurisma da aorta abdominal roto contido crônico (68.4%) do que no grupo controle (84,4%, p=0,04). CONCLUSÃO: Concluímos que o aneurisma da aorta abdominal roto contido crônico representa um desafio diagnóstico e terapêutico, que pode ser adequadamente conduzido com mortalidade precoce e taxas de complicações semelhantes ao aneurisma da aorta abdominal eletivo; entretanto, a mortalidade tardia do aneurisma da aorta abdominal roto contido crônico é maior.

ABSTRACT

OBJETIVO: Avaliar os resultados da cirurgia combinada (endarterectomia carotídea e cirurgia de revascularização do miocárdio) em pacientes com doença carotídea e coronária concomitante. MÉTODOS: Os autores revisam 49 trabalhos que descrevem vários aspectos sobre a cirurgia combinada em um total de 4.788 pacientes, analisando eventos precoces no período peri-operatório. RESULTADOS: As taxas globais de acidente vascular cerebral (AVC), infarto agudo do miocárdio (IAM) e mortalidade foram, respectivamente, de 4,3 por cento; 2,2 por cento; e 4,2 por cento. Para os trabalhos mais recentes (entre 1990-2000), a ocorrência de AVC foi significativamente inferior àquela obtida por trabalhos publicados anteriormente (entre 1972-1989) (4,1 por cento x 10,2 por cento; p < 0,05). Neste mesmo levantamento, os índices de AVC pós-operatórios foram maiores nos artigos que continham uma amostra pequena (n < 50) que naqueles trabalhos com uma população maior (n > 100) (7,2 por cento x 3,9 por cento; p < 0,05), denotando o impacto da experiência dos cirurgiões sobre os resultados pós-operatórios. CONCLUSÃO: Em suma, acreditamos que a cirurgia combinada é um procedimento seguro e eficaz quando realizado por cirurgiões experientes e qualificados.

ABSTRACT

OBJECTIVE: To evaluate the results of combined surgery (carotid endarterectomy and coronary artery bypass grafting) in patients with concomitant carotid and coronary artery disease. METHODS: The authors reviewed 49 different reports describing several aspects of the combined surgery in 4788 patients to analyze early events in the perioperative period. RESULTS: Overall stroke, acute myocardial infarction (AMI), and mortality rates were 4.3%, 2.2%, and 4.2%, respectively. Most recent papers (1990 to 2000) show significant lower incidence of strokes compared to those published earlier (1972 to 1989) (4.1% x 10.2%; p < 0.05). In this same survey, the incidence of postoperative stroke was higher in the series with a small sample (n < 50) than in those with a larger population (n > 100) (7.2% x 3.9%; p < 0.05), denoting the impact of surgeons' experience on postoperative results. CONCLUSION: In sum, we believe that combined carotid endarterectomy and coronary artery bypass grafting is a safe and effective procedure when performed by experienced and qualified surgeons.

ABSTRACT

Objetivo: avaliar os resultados do tratamento cirúrgico deaneurisma da aorta abdominal não-roto em pacientes octogenários,analisando os desfechos a curto e longo prazos nos pacientes com ou sem sintomas relacionados ao aneurisma da aorta abdominal.Pacientes e método: entre março de 1982 e março de 2004,41 pacientes, com idade média de 82,7 anos (variação de 80-89 anos),foram submetidos ao tratamento cirúrgico do aneutisma da aorta abdominal,infra-renal, sendo divididos em dois, grupos, de acordo com os seus sintomas: grupo A (n = 21): asslntomaticos; grupo S (n = 20):sintomáticos. Os resultados foram avaliados pelo teste do X2 , testeexato de Fisher ou teste t quando necessário. A análise da curva de sobrevida foi feita pelo método de Kaplan-Meier. Um valor de P < 0,05 foi considerado estatisticamente significativo.Resultados: a presença de hipertensão arterial, cardiopatia isquêmica e insuficiência renal não diferiu entre os grupos. Sexo mas-culino e tabagismo foram significativamente mais freqüentes no grupo A (P < 0,05). A mortalidade operatória total foi de 9,75 por cento, sendo maior no grupo S (15 versus 4,76 por cento; P = 0,343). A taxa de sobrevida global em 1, 3, 5 e 7 anos foi de 94,2, 67,8, 47,2 e 33 por cento, respectivamente, não sendo estatisticamente diferente entre os grupos.Conclusão: a taxa de mortalidade operatória obtida nos pacientesoctogenários submetidos à cirurgia de aneurisma da aorta abdominal parece ser segura e está de acordo com a literatura. A presença de sintomas aumentou, embora sem força estatística, a mortalidade perioperatória, mas os resultados a longo prazo são semelhantes entre esses dois grupos.

ABSTRACT

Objetivo: Avaliar os resultados da endarterectomia da artéria carótida em pacientes com oclusão da carótida contralateral, revisando-os e comparando-os com os resultados da literatura corrente.Métodos: De janeiro de 1993 a junho de 2003, foram realizadas 663 endarterectomias da artéria carótida, sendo que em 61 pacientes (9,2 por cento) havia oclusão da carótida contralateral. A maioria dos pacientes era do sexo masculino (73,8 por cento), com idade média de 68,2 anos. Hipertensão arterial (70,4 por cento) e tabagismo (72,1 por cento) eram os principais fatores de risco para doença cerebrovascular. Cinqüenta e um pacientes (83,6 por cento) tinham síntomas neurológicos pré-operatórios, sendo a maioria deles correspondente à carótida com estenose (55 por cento). Todos os pacientes relatados foram submetidos a endarterectomia convencional da artéria carótida. Utilizaram-se shunt interno e remendo em 88,5 por cento e 96,2 por cento dos pacientes, respectivamente. Resultados: Dentre as complicações cirúrgicas, dois pacientes (3,3 por cento) necessitaram reexploração cirúrgica por sangramento com hematoma da ferida operatória. Ocorreram três infartos agudos do miocárdio (4,9 por cento), um acidente vascular cerebral(1,6 por cento) e três óbitos (4,9 por cento), sendo dois de origem cardíaca e um resultante de acidente vascular cerebral. Conclusão: O presente estudo demonstrou que a endarterectomia da artéria carótida realizada em pacientes com oclusão da carótida contralateral apresenta mortalidade neurológica de apenas 4,9 por cento, uma percentagem bem inferior à taxa de 14,3 por cento do estudo NASCET, publicado em 1991. A revisão da literatura, publicada a partir da década de 90, evidencia índices de morbimortalidade bem inferiores àqueles relatados pelo estudo.

ABSTRACT

Objetivo: Avaliar a morbidade venosa dos membros inferiores de pacientes submetidos à ressecção da veia femoral superficial. Método: No período de dezembro de 1995 a maio de 2001, foram avaliados oito pacientes submetidos a nove ressecções de veia femoral superficial utilizada para o tratamento de infecção de prótese vascular do segmento aorto-ilíaco-femoral. Todos os pacientes tiveram o sistema venoso dos membros inferiores avaliados de acordo com a classificação CEAP para a insuficiência venosa crônica (sintomatologia clínica, etiologia, locais anatômicos e fisiopatologia) e foram submetidos ao estudo eco-Doppler venoso antes e após a cirurgia. Resultados: Nenhum paciente apresentou edema clinicamente significativo ou sinais de insuficiência venosa crônica nos membros inferiores doadores dos auto-enxertos venosos. O período de acompanhamento variou de 18 a 77 meses. Conclusão: A utilização da veia femoral superficial é uma alternativa cirúrgica segura que pode ser oferecida aos pacientes para o tratamento de infecção de prótese vascular. É mínima a morbidade venosa dos membros inferiores após a ressecção da veia femoral superficial.

ABSTRACT

OBJECTIVE AND METHODS: Screening for abdominal aortic aneurysms may be useful to decrease mortality related to rupture. We conducted a study to assess the prevalence of abdominal aortic aneurysms in southern Brazil and to define risk factors associated with high prevalence of this disorder. The screening was conducted using abdominal ultrasound. Three groups were studied: Group 1 - cardiology clinic patients; Group 2 - individuals with severe ischemic disease and previous coronary surgery, or important lesions on cardiac catheterism; Group 3 - individuals without cardiac disease selected from the general population. All individuals were male and older than 54 years of age. The ultrasonographic diagnosis of aneurysm was based on an anteroposterior abdominal aorta diameter of 3 cm, or on an abdominal aorta diameter 0.5 cm greater than that of the supra-renal aorta. RESULTS: A total of 2.281 people were screened for abdominal aortic aneurysms in all groups: Group 1 - 768 individuals, Group 2 - 501 individuals, and Group 3 - 1012 individuals. The prevalence of aneurysms was 4.3%, 6.8% and 1.7%, respectively. Age and cigarette smoking were significantly associated with increased prevalence of aneurysms, as was the diagnosis of peripheral artery disease. DISCUSSION: We concluded that screening may be an important tool to prevent the mortality associated with abdominal aortic aneurysms surgery. Additionally, the cost of screening can be decreased if only individuals presenting significant risk factors, such as coronary and peripheral artery disease, smokers and relatives of aneurysm patients, are examined.

ABSTRACT

This paper presents a patient successfully treated for leiomyosarcoma of the vena cava, with no recurrence or symptoms on an 8-year follow-up. A 56-year-old woman presented with chronic and progressive periumbilical and right upper abdominal pain. Physical examination and laboratory tests revealed no abnormalities. Computed tomography showed a high-density image inside the vena cava. Cavography showed a filling defect with complete occlusion of the vena cava involving the renal veins and greatly developed collateral circulation through lumbar veins. Laparotomy was performed and a large caval mass involving the renal veins was dissected and resected. Venous reconstruction was undertaken using a 19-mm bovine pericardium prosthesis (Labcor, MG-Brazil) interposed as a substitute to the vena cava, and the renal veins were anastomosed to the side of the graft. Pathologic examination confirmed a leiomyosarcoma with free surgical margins. The postoperative course was uneventful and the patient was discharged on postoperative day 8. The venous flow through the inferior vena became normal, as confirmed by later cavography. This paper presents a case of successfully managed leiomyosarcoma of the vena cava with a thorough review of the literature. The treatment of such patients and the use of bovine pericardium are also discussed.

ABSTRACT

This paper reports a patient who was successfully treated for a ruptured renal artery aneurysm. A 64-year-old man presented with sudden onset of strong abdominal and lumbar pain, and a 2-week history of abdominal discomfort. Abdominal computed tomography and visceral arteriography revealed a retroperitoneal hematoma and a 7.5-cm saccular renal aneurysm with active bleeding. A laparotomy was indicated, and a nephrectomy was performed due to the persistent bleeding and refractory hypotension presented during surgery. The postoperative course was uneventful, and the patient was discharged with a normal renal function on the tenth day. This paper presents the successful management of a ruptured renal aneurysm with a review of the literature, and the management possibilities of such patients is also discussed.
