Introduction In many countries, hemodialysis is still the most common method of renal replacement. Significant regional variations exist in creating and maintaining vascular access for hemodialysis. Therefore, analyzing national registries with vascular access data is essential for developing effective national treatment strategies. The Serbian nat...

Analysis of the influence of risk factors on drug therapy measured by prolongation of the claudication distance in patients with functional lower extremity ischemia (FLEI) can significantly improve the individual approach to the treatment of these patients. The aim of the study was to determine the impact of risk factors on the effectiveness of med...

Idiopathic true aneurysm of the distal radial artery is a rare disease with only few reported cases. Most patients were treated surgically with proximal and distal arterial ligatures, while there are reports of only 7 cases where revascularization procedures were performed. We present a case of a 66-year-old man with a pulsatile mass in the right f...

Introduction Screening of males over 65 years of age for abdominal aortic aneurysm (AAA) has been proved effective in some countries. The incidence of AAA in Serbian population has not been evaluated yet. The aim of the study was to assess the ratio between elective and urgently operated patients with AAA and to estimate hospital incidence of treat...

Background/Aim. Popliteal artery aneurysm (PAA) is the most common peripheral artery aneurysm and second most common aneurysm following abdominal aortic aneurysm (AAA). Still, its incidence is rare and treatment non-standardized. Collection of data in multicenter registry could improve diagnosis and treatment. SerbVasc is newly established data col...

Aim Beside the intention of early detection and optimal treatment of deep venous thrombosis (DVT), the aim of this study was to investigate the influence of chronobiological rhythms on the etiopathogenesis of unprovoked deep vein thrombosis of the lower limbs with monitoring of seasonal variations in biochemical parameters. Patients and methodolog...

Background: The aim of this research was to examine the connection between the circadian pattern of the deep vein thrombosis (DVT) and the demographic charasteristics, the location of the thrombus and the patients' laboratory parameters. Methods: In this prospective clinical examination, there was a total of 153 consecutive lower limb DVT patients...

The aim of this research was to examine the relationship between inflammatory parameters and markers of cholestasis in patients with choledocholithiasis. All subjects underwent clinical, laboratory and ultrasound examination at the Department of Internal Medicine, Military Hospital Niš, Serbia. Inflammatory parameters and biochemical markers of cho...

Despite a lot of progress in the fields of medical imaging and modeling, problem of estimating the risk of in-stent restenosis and monitoring the progress of the therapy following stenting still remains. The principal aim of this paper was to propose architecture and implementation details of state of the art of computer methods for a follow-up stu...

A method for three-dimensional modeling of coronary arteries fusing X-ray angiography and intra vascular ultrasound (IVUS) imaging modalities is presented. A 3-D IVUS catheter path is reconstructed from a pair of biplane angio images taken from same cardiac moment. Vessel wall is segmented from previously image-based ECG gated IVUS images and fused...
