BACKGROUND AND PURPOSE Arachnoid granulations (AGs) of the posterior wall of the temporal bone are a rare cause of spontaneous CSF leakage. The purpose of this study was to investigate the prevalence and appearance of presumed AGs, evidenced by the posterior wall defects of the temporal bone with lobulated or scalloped margins on CT scans. MATERIALS AND METHODS We retrospectively reviewed CT ...

INTRODUCTION The left atrial posterior wall has been shown to play na important role in AF pathophysiology. OBJECTIVE Evaluate the efficacy of an ablation strategy designed to completely isolate the LA posterior wall, on top of PV isolation. Methods and Results: 25 pts (72% male age 65 ± 12 years) undergoing AF ablation for persistent or long term persistent AF. Mean AF duration was 11 ± 3 mo...

patients and methods forty five young female volunteer athletes were included and received different training regimens (endurance-training, strength training and concurrent groups) for a 10 week period as study intervention. standard color doppler echocardiography was performed for assessment of the left ventricular activity. results as a result, 45 athletes ended the study training regimens. m...

Introduction The support anatomy of the posterior vaginal wall is a byproduct of complex interactions among the pelvic floor muscles, nerves, and connective tissue. Before a surgeon can successfully plan and perform an operation to correct a posterior compartment defect, he or she must understand not only the anatomic principles outlined in chapter 1 of this text, but the methods for assessing ...

BackgroundThe standard 12-lead electrocardiogram (ECG) has relatively low sensitivity for the diagnosis of posterior wall acute myocardial infarction (AMI). The prevalence of posterior wall myocardial infarction (MI) has been studied in a few studies. We evaluated ST-segment elevation (STE) prevalence in posterior leads in patients with acute coronary syndrome (ACS) in order to determine the pr...

nasopharyngeal angiofibroma is a relatively uncommon vascular tumor affecting adolescent males and it characteristically originates in the posterior lateral wall of the nasopharynx. primary extra-nasopharyngeal angiofibroma is very rare. here, i present a case of angiofibroma of the parapharyngeal space in a 53-year-old woman with ct and sonographic findings.

To assess regional contractility in idiopathic hypertrophic subaortic stenosis (IHSS), a primary myopathic disorder with documented hyperdynamic ventricular contractions, systolic wall thickening and velocity of contraction of the septum and left ventricular posterior wall were measured in echocardiograms from 16 patients with IHSS and 16 normal subjects. The average thickening of the normal se...

STUDY DESIGN A cadaveric study. OBJECTIVE To investigate possible variations of posterior pharyngoesophageal (PE) wall thickness in the horizontal plane and their implications for anterior spine surgery. SUMMARY OF BACKGROUND DATA Lower cervical levels (C5-7) are most commonly involved in cases of PE injury, and PE wall thickness could be one of the proposed reasons for the high incidence o...

PURPOSE To analyze the correlation between the volume of herniated orbital contents and the amount of enophthalmos in orbital floor and wall fractures. MATERIALS AND METHODS Patients with secondary enophthalmos due to unilateral orbital floor and wall fractures were recruited. Computed tomography-assisted measurements of both orbits as well as of the amount of enophthalmos were performed. The...

OBJECTIVE The aim was to assess pharyngeal airway dimensions and physiological changes based on lateral cephalometric radiographs from healthy untreated children aged 6-17 years. MATERIALS/METHODS The sample consisted of 880 lateral cephalograms (412 females and 468 males) of the Zurich Craniofacial Growth Study. Statistical analyses on cephalometric measurements of airway dimensions (distanc...
