Mitral Valve Area Assessment: Comparison With Transthoracic Echocardiography and Magnetic Resonance...
Mitral Valve StenosisTo compare mitral valve area in rheumatic mitral valve stenosis with cardiac magnetic resonance imaging and conventional transthoracic echocardiography.
The Coexistence of Atherosclerotic Intracranial Arterial Stenosis With Intracranial Aneurysms
Atherosclerotic Intracranial Arterial Stenosis With Intracranial AneurysmsAtherosclerotic intracranial arterial(ICA) stenosis and intracranial aneurysms are the common causes of ischemic stroke and hemorrhagic stroke, respectively. Investigators aimed to assess the prevalence of cerebral aneurysms in patients with atherosclerotic intracranial arterial stenosis.
Cerebrospinal Fluid Congestion in Spinal Stenosis Patients
Spinal StenosisThe investigators hypothesized spinal stenosis symptom was provocation due to cerebrospinal fluid congestion.
Microbiological Examination of Children Operated for Congenital Lacrimal Stenosis
Congenital Lacrimal StenosisChildren with congenital lacrimal stenosis are treated by probing and intubation of the lacrimal drainage system. Hypothesis: Microbiological findings at the time of insertion and removal of the silicon intubation have an influence on the clinical outcome and success rate of the surgical treatment. Microbiological specimens are taken from conjunctiva and nasal mucosa during the two procedures under general anaesthesia and from the silicon tube after removal and examined for bacterial contamination.
