renal artery obstruction/カリウム

The case is reported of a young woman with severe hypertension, unilateral renal artery stenosis, variously normal or marginally high plasma concentrations of active renin, angiotensin II, aldosterone, sodium, and potassium; and normal total exchangeable and total body sodium and potassium.

The converting enzyme inhibitor enalapril, in single daily doses of 10 to 40 mg, was given to 20 hypertensive patients with renal artery stenosis. The decrease in blood pressure six hours after the first dose of enalapril was significantly related to the pretreatment plasma concentrations of active

The converting enzyme inhibitor, enalapril, was given to 20 hypertensive patients with renal artery stenosis in a single daily dose of 10-40 mg. Enalapril effectively controlled hypertension long-term, and only two of the 20 patients required concomitant diuretic treatment. The blood pressure

The converting enzyme inhibitor enalapril, in single daily doses of 10-40 mg, was given to 20 hypertensive patients with renal artery stenosis. The blood pressure fall six hours after the first dose of enalapril was significantly related to the pretreatment plasma concentrations of active renin and

Measurements of exchangeable sodium, arterial pressure and plasma concentrations of active renin, angiotensin II, aldosterone, sodium and potassium were made in 35 hypertensive patients with renal artery stenosis, 30 having unilateral renal arterial lesions. Plasma urea was below 7 mmol/l in 24 of

This report describes two infants with severe arterial hypertension secondary to unilateral renal artery stenosis which was manifested by polyuria, polydipsia, hypokalemic alkalosis, hyponatremia, increased natriuresis and increased plasma values of rennin and aldosterone. On sonographic

Background: Rare cases of concurrent primary aldosteronism (PA) and renal artery stenosis (RAS) have been reported. Methods: In this retrospective case-control study, we

We report the case of a 42-year-old male who was admitted to our hospital after an acute hypertensive crisis despite four-way anti-hypertensive therapy. The renal scintigraphy, the excretory urogram and the biochemical profile performed two years before were unremarkable, except for slightly

Hypokalemia is an uncommon presentation of renovascular hypertension. Although renal artery stenosis has been associated with hypokalemia secondary to hyperreninemic hyperaldosteronism, few reports have actually evaluated the pathophysiologic changes in such a patient with renovascular hypertension.

Renovascular hypertension is one of the common causes of secondary hypertension. Here we report a case of patient of renal artery stenosis presenting to the emergency department as a case of acute flaccid paralysis. Renal artery stenosis has been associated with hypokalaemia, but rarely reported to

Enalapril maleate (MK421), a new inhibitor of angiotensin converting enzyme, in single daily doses of 1.25-40 mg was assessed in five patients with hypertension and renal artery stenosis. Only small falls in plasma angiotensin II concentrations were seen at doses less than 10 mg; even with 10 and 20

The converting enzyme inhibitor, ramipril, 20 mg once daily, was given to 3 hypertensive patients with unilateral renovascular disease. At 1 month, 24 hours after the last dose of ramipril, blood pressure, plasma angiotensin II and converting enzyme activity remained low, and active renin and

A 54-year-old man with diabetes mellitus, peripheral vascular disease, and hypertension was admitted to the hospital for an acute exacerbation of chronic heart failure. Therapy with intravenous furosemide and oral losartan 100 mg twice/day was begun. Ten days later, the patient's blood urea nitrogen

Fifteen patients with hypertension and unilateral renal artery disease were treated with captopril alone; 10 came to operation and were later assessed postoperatively with no drug treatment. Captopril caused both immediate and sustained decreases in plasma angiotensin II and aldosterone, with

Deterioration in renal function after the use of angiotensin converting-enzyme inhibitors may be the first clue to the presence of bilateral renal arterial stenosis. In order to avoid serious threat to the patient, early detection of the insidious decline in renal function is necessary and depends
