“…This finding confirms results of earlier studies with lower number of investigated patients. 9,10 Accessory renal arteries based on autopsy studies are seen in 20-30% of normal patients. 11,12 In this study similar prevalence of the accessory renal arteries to such autopsy data was found only in the young patients.…”

Renal artery stenosis (RAS) is an important cause of arterial hypertension and chronic kidney disease. The aims of our study were to assess the prevalence of RAS and to examine the frequency of variants of renal vasculature, that is, multiple and/or accessory renal arteries in hypertensive patients referred to renal angiography. We evaluated retrospectively 1554 arteriographies of hypertensive patients. Angiograms were evaluated to find RAS, significant RAS (460% stenosis of the lumen), radiological signs of atherosclerosis, aneurysms of the renal arteries or aorta and variants of kidney vascularization. The frequency of RAS including occlusions was 15.1% (21.3% of them were significant and suitable for revascularization). Variants of renal arterial vascularization were found in 26.5% of patients (multiple renal arteries-11.2% and accessory renal arteries-15.3%). Significant RAS was found more frequently in patients older than 60 years-OR 4.76 (2.08-10.86). Coronary artery disease, history of myocardial infarction or stroke significantly increased the chance of RAS detection. The frequency of renal accessory arteries was lower in patients older than 60 years and in patients with the radiological signs of atherosclerosis. Results of this study indicate that haemodynamically important RAS is found more frequently in hypertensive patients older than 60 years. Symptomatic atherosclerotic disease found in the peripheral and/or coronary arteries and diabetes mellitus increases the chance of RAS detection. Decreased occurrence of renal accessory arteries was found in hypertensive patients with radiological signs of atherosclerosis.

“…Está documentada na literatura, a normalização da pressão arterial após ressecção das artérias renais acessórias. Outros autores 10 afirmam que as artérias renais acessó-rias não aumentam o risco de HTA, referindo que a prevalência de estenose da artéria renal nos doentes com e sem artérias renais acessórias, não é estatisticamente significativa.…”

Hipertensão Arterial Sistémica Secundária: Incertezas do Diagnóstico

RESUMOA hipertensão arterial sistémica configura-se hoje como um problema de saúde pública mundial, sendo a taxa de prevalência em Portugal de 26,9%. De acordo com a sua etiologia classifica-se em hipertensão arterial sistémica primária ou secundária. Em cerca de 90% dos casos, não é possível estabelecer uma causa e por isso a hipertensão arterial sistémica denomina-se primária. Nos restantes 5% a 10%, pode ser identificada uma causa secundária, potencialmente tratável. Para que o estudo da hipertensão arterial sistémica secundária seja custo-eficaz, torna-se essencial perceber quais os doentes a investigar, com que meios, e qual a melhor estratégia a adotar. As principais causas apontadas como responsáveis pela hipertensão arterial sistémica secundária são: patologia renal; endócrina; vascular e síndrome da apneia obstrutiva do sono. Entre estas, algumas são consensuais e outras mais controversas na literatura. A este propósito apresentamos dois casos de hipertensão arterial sistémica, cuja etiologia potencialmente secundária ainda é foco de debate. Palavras-chave: Artéria Renal/anomalias congénitas; Doenças Renais Quísticas; Hipertensão/diagnóstico; Pressão Sanguínea ABSTRACTArterial hypertension is regarded today as a global public health problem, and the prevalence rate in Portugal is 26.9%. According to the etiology, is classified into primary or secondary arterial hypertension. In about 90% of cases it is not possible to establish a cause, so is called primary arterial hypertension. In the remaining 5 to 10%, it can be identified secondary causes, which are potentially treatable. For secondary arterial hypertension study to be cost-effective, it is essential to understand which patients investigate, and evaluate the best strategy to adopt. The main causes identified as responsible for secondary arterial hypertension are: kidney disease; endocrine and vascular diseases and obstructive sleep apnea. Among these some are consensual, and others more controversial in the literature. In this regard we present two cases of arterial hypertension, which are potentially secondary in etiology, but still focus of debate. Keywords: Blood Pressure; Hypertension/diagnosis; Kidney Diseases, Cystic; Renal Artery/abnormalitie INTRODUÇÃO A hipertensão arterial (HTA) é um fator de risco major para doença cardiovascular.1,2 A HTA secundária define-se como um aumento da pressão arterial devido a uma causa identificável, 3 ocorrendo em 5% -10% de todos os casos de HTA.4 Devido a esta baixa percentagem, é primordial saber que doentes devemos estudar. A história clínica e o exame objetivo são instrumentos valiosos para guiar o clínico nesta seleção.A HTA secundária está associada a uma patologia potencialmente tratável, requerendo alto grau de suspeita. Na pesquisa inicial devemos excluir a HTA de bata branca, aferir a adesão terapêutica e identificar sinais e sintomas indicadores de HTA secundária. Devemos estudar jovens sem outros fatores de risco cardiovasculares (FRCV); HTA de início recente ou previamente controlada; HTA com l...
