Though RV ablation is reported as having been successful, it would be interesting to know for how long the patient was followed-up after the procedure. This point is of particular importance since the patient is reported to have undergone RV ablation already before (ablation 1) the present procedure (ablation 2). How long was the interval between ablation 1 and ablation 2? For how long was abla...
PURPOSE To identify changes in plasma cytokine levels after image-guided thermal ablation of human tumors and to identify the factors that independently predict changes in plasma cytokine levels. MATERIALS AND METHODS Whole-blood samples were collected from 36 patients at three time points: before ablation, after ablation (within 48 hours), and at follow-up (1-5 weeks after ablation). Plasma ...
In the present study, we evaluated the effects of eyestalk ablation, Ovaprim hormone injected and sterile vehicle solution injected (control) on maturation, Ovarian tissue and biochemical changes in Litopenaeus vannamei. Sterile vehicle solution and hormone injections at 500 and 1000 ng/g body weight were performed with a 100 μl volume in three steps (0, 7 and 14 days). We examined 60 females a...
In this study, we investigated the effects of different levels of dietary nucleotide (0, 0.2, 0.4 and 0.6%) on immunity parameters and total protein plasma of Litopenaeus vannamei female brood stock in four experimental treatments (three replication per treatment) during the maturation period and after eye stalk ablation. Total soluble proteins and immunity parameters such as total haemocyte co...
Background: Thyroid cancer is the most prevalent malignancy of the endocrine systemcancers. Thyroid cancer has increased faster thatn any other malignancy in recent years. Tyroid cancer has different histopathologic types, of which the most common is the differentiated type. Different factors can affect the prognosis of the patients. In this study, we investigated different factors that can aff...
BACKGROUNDS Idiopathic ventricular arrhythmias (VAs) originating from the left ventricular outflow tract (LVOT) sometimes require catheter ablation from the endocardial and epicardial sides for their elimination, suggesting the presence of intramural VA foci. This study investigated the efficacy of sequential and simultaneous unipolar radiofrequency catheter ablation from the endocardial and ep...
BACKGROUND Atrial fibrillation (AF) is a leading cause of total and fatal ischemic stroke. Stroke risk after AF ablation appears to be favorably affected; however, it is largely unknown whether the benefit extends to all stroke CHADS2 risk profiles of AF patients. OBJECTIVE To determine if ablation of atrial fibrillation reduces stroke rates in all risk groups. METHODS A total of 4212 conse...
BACKGROUND The aim of this study was to investigate the feasibility of the application of high-intensity focused ultrasound (HIFU) hat-type ablation mode in in vitro and in vivo models, and to compare the ablation effects of different parameter combinations. MATERIAL AND METHODS HIFU hat-type ablation was performed in isolated bovine liver tissue and in the liver tissue in living rabbits, and t...
BACKGROUND It is well established that radiofrequency (RF) ablation is the most cost effective treatment strategy for patients with supraventricular tachycardia. Previous cost estimates assumed at least an overnight stay following RF ablation. Day stay RF ablation however appears to be a safe alternative. AIMS The aim of this study was to compare day stay and inpatient catheter ablation in te...
Ablation of ventricular tachycardia (VT) by conventional radiofrequency ablation can be impossible if the ventricular wall at the targeted ablation site is very thick, as for example the ventricular septum. We present a case of a patient with incessant, non-sustained slow VT originating from the septal part of the lower outflow tracts. Radiofrequency catheter ablation from both ventricles as we...
