Abstract
Background: Renal denervation is a novel therapeutic option in resistant hypertension (RHT). The
anatomy of renal arteries and the presence of additional renal arteries are important determinants of
the effect of the procedure. The aim of this study was to assess the anatomy of renal arteries using angio-
-computed tomography in patients with RHT, who were qualified for renal denervation.
Methods: We analyzed angio-computed tomography scans of the renal arteries of 72 patients qualified
for renal denervation. We divided the study population into two groups: a resistant hypertension group
(RHT) and a pseudo-resistant hypertension group (NRHT). The biochemical and endocrine diagnostic
procedures were performed to rule out secondary hypertension. We analyzed the morphology, the diameters,
and the number of additional renal arteries.
Results: In both groups, we found additional renal arteries (ARN). ARN were more frequent in
RHT than in patients with non-resistant hypertension (48.4% vs. 24.3%; p < 0.05). They were
present more often on the left side (18 left side vs. 7 right side). The ARNs were longer than main
renal artery — left side 41.7 ± 12.1 mm vs. 51.1 ± 11.8 mm, right side 49.2 ± 14.5 mm vs. 60 ±
± 8.6 mm, respectively (p < 0.05). The diameters of ARN were similar in both groups. In the group of
patients with RHT the number of ARN was significantly higher (p < 0.04).
Conclusions: The ARNs occur more often in patients with RHT. It seems that there is no connection
between the resistance of hypertension and the diameters of renal arteries.
