Screening for congenital renovascular hypoplasia and renal artery stenosis by acute converting enzyme inhibition.

To evaluate the usefulness of the captopril test for identifying renal artery stenosis (RAS) and renovascular hypoplasia (RAH), we studied 48 hypertensive patients. In 20 hypertensives with screening procedures indicating renovascular disease and in 28 essential hypertensives (EH), the plasma renin activity (PRA) responses to an oral test dose of captopril (50 mg) were studied. A 60-min post-captopril PRA increase of 150% (or 400% if baseline PRA < or = 3 ng/ml/h) was considered as positive. Renal angiography was performed in all cases. Among the 20 renovascular hypertensive patients, RAH in 9 and RAS in 11 subjects were proved by angiography. The captopril test in all patients with RAH res…

Anomalous origin of bronchial arteries in patients with cystic fibrosis: therapeutic implications for embolisation.

Bronchial artery embolisation (BAE) is an accepted method of controlling haemoptysis in patients with cystic fibrosis. However, anomalous origin of the bronchial arteries, documented in anatomical and angiographic studies, makes the procedure more difficult and increases the number of recurrences. Clinical records and films from three patients affected by cystic fibrosis with haemoptysis, in which the origin of the bleeding vessels was considered anomalous, out of a total of seven patients who underwent BAE, were reviewed. In two patients the source of bleeding was identified from, respectively, the left and the right internal mammary artery and in one from the left thyrocervical trunk. All…
