Quantitative analysis of digital subtraction renal vasography in patients with autosomal dominant polycystic kidney disease correlated with clinical and paraclinical data.

Digital intravenous subtraction angiography (DSA) of the kidneys provides an alternative means to achieve better screening of suspected, symptomless and unclear forms of autosomal dominant polycystic kidney disease (ADPKD). The method's capabilities for a quantitative analysis makes it particularly useful in patients with arterial hypertension. We report our experience in using DSA in 36 patients of whom 11 were with proven ADPKD and 15 with suspected ADPKD. The results analysed were correlated with laboratory data obtained in 28 healthy subjects. The importance of the intravenous DSA is underscored as a possible investigation modality for a quantitative analysis in relatively normal haemodynamic conditions of imaging the two kidney's symmetrically and normal conditions for comparison.
