Laryngeal Paralysis: Pathophysiology, Diagnosis, and Surgical Repair
CE Dysfunction of the recurrent laryngeal nerves causes laryngeal paralysis in dogs and cats. Paralysis of the cricoarytenoideus dorsalis muscle results in an inability to abduct the arytenoid cartilages during inspiration.The resulting cross-sectional area of the glottis is inadequate for normal respiration.The most common clinical signs of laryngeal paralysis in dogs and cats are stridor, exe...
متن کاملCervical Spondylotic Myelopathy: Pathophysiology, Diagnosis, and Surgical Techniques
Cervical spondylotic myelopathy is a degenerative spinal disease which may lead to significant clinical morbidity. The onset of symptoms is usually insidious, with long periods of fixed disability and episodic worsening events. Regarding the pathophysiology of CSM, the repeated injuries to the spinal cord are caused by both static and dynamic mechanical factors. The combination of these factors...
متن کاملPathophysiology of Minimally Invasive Surgical Approaches: Current Concepts.
Spine surgery is a continuously evolving field. Traditional posterior midline approaches to the lumbar spine are associated with muscle injury. Common mechanisms of injury include ischemia, denervation, and mechanical disruption of tendinous attachments of lumbar muscles. Muscle injury may be documented with chemical markers (creatinine kinase, aldolase, proinflammatory cytokines), by imaging s...
متن کاملEarly surgical anteroseptal ventricular endocardial restoration after acute myocardial infarction. Pathophysiology and surgical considerations.
BACKGROUND The efficacy and safety of surgical anteroseptal ventricular endocardial restoration (a procedure that excludes non-contracting scarred segments) in the left ventricle with chronic dilation and remodeling secondary to an anterior myocardial infarction are well established. We present a small series and discuss the indication for early left ventricular restoration in the setting of co...
متن کاملO6: Pathophysiology of Anxiety Disorders
The most important risk factors for anxiety disorders include genes, early life stress, and current stress. These factors do not act independently but interact with each other throughout human development through examples such as epigenetic modifications and complex forms of learning. The neural substrate of pathological anxiety includes hyperactivity in the amygdala and other limbic brain regi...
