Diagnostic criteria for the determination of clinically significant internal carotid artery stenosis using duplex ultrasound.

Background: Carotid endarterectomy is beneficial in symptomatic patients with ≥70% stenosis at the bifurcation of the internal carotid artery. The fact that the duplex ultrasound is widely used, inexpensive and non-invasive for examination of the carotid arteries underlines the importance of high accuracy of this method for grading internal artery stenosis.

Patients And Methods: Duplex scans and arteriograms of carotid arteries of 142 patients were reviewed.

The effect of renal denervation in an experimental model of chronic renal insufficiency, The REmnant kidney Denervation In Pigs study (REDIP study).

Background: Renal denervation (RDN) is a promising therapeutic method in cardiology. Its currently most investigated indication is resistant hypertension. Other potential indications are atrial fibrillation, type 2 diabetes mellitus and chronic renal insufficiency among others.

Percutaneous Mechanical Thrombectomy Using Rotarex® S Device in Acute Limb Ischemia in Infrainguinal Occlusions.

Purpose: To evaluate the effectiveness of percutaneous mechanical thrombectomy using Rotarex S in the treatment of acute limb ischemia (ALI) in infrainguinal occlusions in a retrospective study of patients treated in our institution.

Methods: In this study, we identified a total of 147 ALI patients that underwent mechanical thrombectomy using Rotarex S at our institution. In 82% of the cases, percutaneous thrombectomy was used as first-line treatment, and for the remainder of the cases, it was used as bailout after ineffective aspiration or thrombolysis.

[A rare case of mobile atherosclerotic plaque with a high embolic potential in the femoral artery].

Atherosclerosis is a diffuse disease which may lead to the development of unstable atherosclerotic plaque. Its rupture can result in acute ischemic event. The atherosclerotic plaques with a mobile component are typical presentations of such instability and patients with these plaques are at high risk of acute ischemic events.

Renal denervation decreases effective refractory period but not inducibility of ventricular fibrillation in a healthy porcine biomodel: a case control study.

Background: Ventricular arrhythmias play an important role in cardiovascular mortality especially in patients with impaired cardiac and autonomic function. The aim of this experimental study was to determine, if renal denervation (RDN) could decrease the inducibility of ventricular fibrillation (VF) in a healthy porcine biomodel.

Methods: Controlled electrophysiological study was performed in 6 biomodels 40 days after RDN (RDN group) and in 6 healthy animals (control group).

[Deep calf vein thrombosis].

Isolated calf vein thrombosis in the population of patients with deep vein thrombosis is found approximately in 10 to 25 % of cases. We present 3 cases of calf vein thrombosis which occurred due to unusual causes. Specific characteristics of this form of thromboembolic disease are discussed and compared to proximal deep vein thrombosis with emphasis to symptoms, risk of complications, prognosis and therapeutic approach.
