Hipertensão renovascular / Renovascular hypertension

Estenoses da artéria renal (EAS) é um estreitamento ou bloqueio de uma artéria para os rins. Pode causar insuficiência renal e pressão alta. Fumantes e ex-fumantes têm maior risco de contrair RAS. Os homens são afetados com essa condição duas vezes mais que as mulheres. É mais comum nas idades de 50 e 70. Colesterol alto, diabetes, excesso de peso e histórico familiar de doenças cardíacas também são fatores de risco para RAS. A pressão alta é uma causa e resultado do RAS. A causa mais comum de bloqueio da artéria renal é a arteriosclerose (espessamento e endurecimento das paredes da artéria) com acúmulo de colesterol e placa. Isso é semelhante ao que é visto nas artérias coronárias do coração, nas artérias carótidas, no cérebro e nos vasos das pernas. Apresentamos um caso de doença vascular renal em um homem diabético e ex-fumante e é apresentada uma atualização sobre a doença.

Renal artery stenoses (RAS) is a narrowing or blockage of an artery to the kidneys. It may cause kidney failure and high blood pressure. Smokers and ex-smokers have a greater risk of getting RAS. Men are affected with this condition twice as often as women. It>s most common in the ages of 50 and 70. High cholesterol, diabetes, being overweight, and having a family history of heart disease are also risk factors for RAS. High blood pressure is both a cause and a result of RAS. The most common cause of renal artery blockages is arteriosclerosis (the thickening and hardening of artery walls) with cholesterol and plaque build-up. This is similar to what is seen in the coronary arteries of the heart, the carotid arteries to the brain and the leg vessels.We presente a case of renal vascular disease in a diabetic and ex-smoker man and an up to date about the disease is presented.

Clinical observation of intraluminal stent angioplasty in the treatment of renal arterial stenoses / 介入放射学杂志

Objective To evaluate the clinical application of intraluminal stent angioplasty(PTRAS) in the treatment of renal arterial stenoses. Methods A retrospective study was done in 28 patients with renal arterial stenoses. Primary renal artery stenting was performed in 28 consecutive patients (36 renal arteries). Blood pressure, serum creatine, the number of anti hypertensive medications were recorded at 1,6,12 month post stent angioplasty respectively. Arterial angiography was also taken 1 year later to evaluate the incidence of restenosis. Results Technical success rate was 100% achiving in all patients without serious complications. Primary successful patenty rate reached 82% (renal artery 86%), secondary successful rate was 89% (renal artery 90%). Systolic and diastolic blood pressure were reduced significantly ( P
