Unlabelled: Comparison of immediate angiographical and clinical results of direct coronary stenting and stenting after predilation was carried out in 68 patients. Groups of patients subjected to direct stenting and stenting with predilation had similar clinical and angiographical characteristics. Direct stenting was successful in 100%, stenting with predilation--in 97.2% of patients with residual stenosis 5.1 and 4.9%, respectively. There were no cases of stent loss, death or emergent bypass grafting during neither the procedure nor period of hospitalization. There was 1 Q-wave myocardial infarction (2.8%) and 2 non-Q wave myocardial infarctions (1 in each group). Compared with stenting with predilation procedure of direct stenting was associated with significantly shorter procedure duration (39-/+7.1 min, 60-/+12.5 min, respectively), radiation exposure time (7.9-/+6.3 and 13.5-/+8.9 min, respectively), lower workload of the laboratory (4.9-/+3.5 and 6.1-/+2.0 patients/day, respectively), decreased consumption of contrast medium (200-/+71 and 275-/+75.9 ml, respectively), and thus lower overall cost of the procedure.
Conclusion: Direct coronary stenting is a convenient, safe and economically justified method of stent implantation.

Background: Preinjury antithrombotic (AT) use is associated with worse outcomes for geriatric (65 years or older) patients with traumatic brain injury (TBI). Previous studies have found that use of AT outside established guidelines is widespread in TBI patients.
Methods: In this single-center retrospective cross-sectional study, we examined inappropriate AT use among geriatric patients presenting with traumatic intracranial hemorrhage.

Background And Purpose: Endovascular thrombectomy (EVT) for acute ischemic stroke (AIS) with M2 segment occlusion of the middle cerebral artery (MCA) is debatable. This study assessed the efficacy, safety, and functional outcomes of EVT in M2 occlusion patients, examining differences in outcomes based on the dominance of the occluded segment (DomM2 vs. Non-DomM2).

Introduction: In adult patients, most ureteropelvic junction obstruction (UPJO) occurs secondarily. Concurrent UPJO with nephrolithiasis is not rare and simultaneous treatment by performing laparoscopic pyeloplasty and endoscopic stone removal has been suggested. In the case of atypical anatomy or previously failed pyeloplasty, a laparoscopic ureterocalicostomy is preferred.

Introduction: Advances in pharmacotherapy for coronary thrombosis treatment and prevention have transformed the clinical outcomes of patients with coronary artery disease but increased the complexity of therapeutic decision-making. Improvements in percutaneous coronary intervention techniques and stent design have reduced the incidence of thrombotic complications, which consequently has increased the challenge of adequately powering clinical trials of novel antithrombotic strategies for efficacy outcomes. Knowledge of the pathophysiology of coronary thrombosis and the characteristics of antithrombotic drugs can help with therapeutic decisions.
