ABSTRACT

Abstract Background: Transplant Renal Artery Stenosis (TRAS) is a recognized vascular complication after kidney transplantation. The overall risk predictors of TRAS are poorly understood. Methods: Retrospective analysis of patients with suspected TRAS (Doppler ultrasound PSV > 200 cm/s) who underwent angiographic study in a single center between 2007 and 2014. All patients with stenosis > 50% were considered with TRAS. Stenosis restricted in the body of the artery was also analyzed in a subgroup. Results: 274 patients were submitted to a renal angiography and 166 confirmed TRAS. TRAS group featured an older population (46.3 ± 11.0 vs. 40.9 ±14.2 years; p = 0.001), more frequent hypertensive nephropathy (30.1% vs. 15.7%; p = 0.01), higher incidence of Delayed Graft Function (DGF) (52.0% vs. 25.6%; p < 0.001) and longer Cold Ischemia Time (CIT) (21.5 ± 10.6 vs. 15.7 ± 12.9h; p < 0.001). In multivariable analyses, DGF (OR = 3.31; 95% CI 1.78-6.30; p < 0.0001) was independent risk factors for TRAS. DM and CIT showed a tendency towards TRAS. The compound discriminatory capacity of the multivariable model (AUC = 0.775; 95% CI 0.718-0.831) is significantly higher than systolic blood pressure and creatinine alone (AUC = 0.62; 95% CI 0.558-0.661). In body artery stenosis subgroup, DGF (OR = 1.86; 95% CI 1.04-3.36; p = 0.03) and Diabetes Mellitus (DM) (OR = 2.44; 95% CI 1.31-4.60; p = 0.005) were independent risk factors for TRAS. Conclusion: In our transplant population, DGF increased more than 3-fold the risk of TRAS. In the subgroup analysis, both DGF and DM increases the risk of body artery stenosis. The addition of other factors to hypertension and renal dysfunction may increase diagnostic accuracy.

ABSTRACT

Há 22 anos, um curso informativo de cirurgia plástica para acadêmicos de medicina, promovido pela integração de quatro escolas médicas, três universidades e pela regional da Sociedade Brasileira de Cirurgia Plástica vem sendo ministrado, contribuindo para a educação médica em Curitiba, uma cidade de dois milhões de habitantes, em uma área metropolitana de aproximadamente três milhões de pessoas. Este curso informativo proporciona uma visão abrangente da especialidade, para que acadêmicos de medicina possam avaliar sua vocação pessoal para o exercício da cirurgia plástica, além de fornecer conhecimentos básicos indispensáveis à formação de qualquer médico. Anualmente o curso é ministrado em 47 horas e ofertado para 120 alunos. O programa inclui 70% de "cirurgia reconstrutiva" e 30% de "cirurgia estética", sendo a maioria dos professores membros titulares da Sociedade Brasileira de Cirurgia Plástica. Nos primeiros 19 anos de atividade (1992 a 2010), 4,6% dos alunos que concluíram o curso cursaram residência em cirurgia geral, foram admitidos na residência em cirurgia plástica e hoje fazem parte da Sociedade Brasileira de Cirurgia Plástica. O curso tornou-se um importante instrumento de educação médica, complementando o currículo de quatro escolas médicas e promovendo a cirurgia plástica como especialidade única e indivisível, enfatizando a importância da prova de especialista em cirurgia plástica e a conveniência da escolha e da indicação destes especialistas para a realização de qualquer procedimento no âmbito da cirurgia plástica.


For 22 years, a reproducible introductory overview course on plastic surgery for medical students, cosponsored by four medical schools, three universities and the regional chapter of the Brazilian Society of Plastic Surgery (SBCP), has contributed to medical education in Curitiba, a city of 2 million, and serving a metropolitan population of nearly 3 million people. This course helps medical students determine if plastic surgery is the right choice for them and provides valuable information about the specialty itself that will serve all participants as they go forward into their chosen fields, as plastic surgeons or not. This broad-ranging 47 hour course, limited to 120 students, is fully enrolled every year. Its content is weighted approximately 70% toward reconstructive plastic surgery and 30% toward aesthetic plastic surgery. Most lectures are presented by plastic surgeons who are full members of the SBCP. During its first 19 years of operation, 4.6% of the students completing the course have gone on to a general surgery residency followed by a plastic surgery residency, and are current SBCP members. The course has become a valuable educational and marketing tool for the regional chapter of the SBCP. It promotes the unique scope of the specialty and increases awareness among participants, as well as among their many personal and professional contacts (currently and in the future) about the benefits of becoming fully qualified, board-certified plastic surgeons.
