Risks and benefits of renal artery stenting in fibromuscular dysplasia: Lessons from the ARCADIA-POL study.

Introduction: Although renal stenting is the standard revascularization method for atherosclerotic renal artery stenosis (RAS) (FMD-RAS), stenting in fibromuscular dysplasia (FMD) RAS is usually limited to periprocedural complications of angioplasty and primary arterial dissection. The main aim of the study was to retrospectively analyze the immediate and long-term results of renal stenting versus angioplasty in patients with FMD.

Methods: Of 343 patients in the ARCADIA-POL registry, 58 patients underwent percutaneous treatment due to FMD-RAS (in 70 arteries).

OBJECTIVES The aim of the study was to evaluate intrarenal blood flow parameters in patients with FMD and significant or nonsignificant renal artery stenosis (RAS). PATIENTS AND METHODS We evaluated intrarenal blood flow parameters by Doppler ultrasonography in 153 patients with renal FMD enrolled in the ARCADIA‑POL study: 32 and 121 patients with and without significant RAS, respectively, compared with 60 matched patients with essential hypertension and 60 healthy controls.

Silent Cerebral Infarcts Following Left-Sided Accessory Pathway Ablation in Wolff-Parkinson-White (WPW) Syndrome: A Preliminary Report.

BACKGROUND Catheter ablation is a routine procedure in patients with WPW syndrome. Silent cerebral infarcts (SCI) detected in magnetic resonance imaging may be a complication of the ablation procedure, but it is well documented only in atrial fibrillation ablation. Ablation of left-sided accessory pathways (L-AP) has a similar target area, but WPW patients differ from those with atrial fibrillation, due to lower initial risk of cerebral embolic events.

High incidence and clinical characteristics of fibromuscular dysplasia in patients with spontaneous cervical artery dissection: The ARCADIA-POL study.

The association between fibromuscular dysplasia (FMD) and spontaneous cervical artery dissection (SCeAD) has been recognized, but the available evidence on this relationship is scant. Therefore, the main goal of our study was to systematically evaluate FMD frequency, clinical characteristics and vascular bed involvement in patients with SCeAD. Among 230 patients referred to the ARCADIA-POL study, 43 patients (mean age 44.

Management of carotid stenosis. History and today.

Internal carotid stenosis constitutes a significant clinical challenge, since it is the cause of 20-25% of ischemic brain strokes. The management of the internal carotid stenosis for many years has been raising controversies amongst neurologists, vascular surgeons and interventional radiologists mainly due to the introduction of endovascular stenting as an alternative to surgical treatment. Its application, however, requires knowledge of specific selection criteria for this kind of treatment as well as of the methods of monitoring patients after stent implantation into the internal carotid artery.
