1/154. Chronic aneurysm of the descending thoracic aorta presenting with right pleural effusion and left phrenic paralysis.A 62-year-old man was admitted to the emergency department with chronic dysphagia and lower back pain. Chest radiography revealed a wide mediastinal shadow and an elevated left diaphragm, which proved to be secondary to left phrenic paralysis. The patient was diagnosed with an aneurysm of the descending thoracic aorta and was admitted to the hospital. After the patient was admitted, the aneurysm ruptured into the right chest. The patient underwent an emergency operation to replace the ruptured segment with a synthetic graft. Postoperative recovery and follow-up were uneventful. This report describes an unusual presentation of a thoracic aortic aneurysm. Hemidiaphragmatic paralysis caused by compression of the phrenic nerve is an unusual complication that, to our knowledge, has not been previously reported.- - - - - - - - - - ranking = 1keywords = paralysis (Clic here for more details about this article) |
2/154. Diaphragmatic paralysis due to lyme disease.lyme disease is a tick-borne spirochaete infection which, in a proportion of patients, can lead to neuropathy. This article describes a case of diaphragmatic paralysis due to lyme disease. A 39-yr-old male presented to the hospital because of an acute left facial palsy. Six weeks prior to admission he had developed a circular rash on his left flank during a camping holiday. He also complained of shortness of breath and arthralgia for 1 week. His chest radiograph demonstrated a raised right hemi-diaphragm. Diaphragmatic paralysis was confirmed by fluoroscopy (a positive sniff test). serology revealed evidence of recent infection by borrelia burgdorferi. On the basis of the patient's clinical presentation, a recent history of erythema migrans, and positive Lyme serology, a diagnosis of neuroborreliosis was made. He received oral doxycycline therapy (200 mg x day(-1)) for three weeks. Facial and diaphragmatic palsies resolved within eight weeks. On the basis of this case, a diagnosis of lyme disease should be considered in patients from endemic regions with otherwise unexplained phrenic nerve palsy.- - - - - - - - - - ranking = 1keywords = paralysis (Clic here for more details about this article) |
3/154. Reversibility of paraneoplastic bilateral diaphragmatic paralysis after nephrectomy for renal cell carcinoma.Bilateral diaphragmatic paralysis is usually caused by anatomic lesions of both phrenic nerves (e.g., after cardiothoracic surgery), generalized neurologic diseases (e.g., primary motor neuron disease, amyotrophic lateral sclerosis) or is without a known cause (idiopathic). We report a case of a patient with renal cell carcinoma complicated by an isolated bilateral diaphragmatic paralysis without clinical or electromyographic signs of other muscle or nerve involvement. There has been progressive, though till now partial, recovery of his vital capacity rising from 44% to 72% of predicted values, and maximal inspiratory pressures during the two years following the curative resection of his renal cell carcinoma. We believe this is the first report of a paraneoplastic bilateral diaphragmatic paralysis with actual recovery after tumour therapy.- - - - - - - - - - ranking = 1.1666971478417keywords = paralysis, idiopathic (Clic here for more details about this article) |
4/154. Bilateral diaphragm paralysis secondary to central von Recklinghausen's disease.Bilateral paralysis of the diaphragm is either idiopathic or associated with several medical conditions, including trauma or thoracic surgery, viral infections, and neurologic congenital or degenerative disorders. We describe the case of a 36-year-old man with a history of neurofibromatosis who developed severe bilateral diaphragmatic paralysis from involvement of the phrenic nerve roots with neurofibromas. The patient manifested progressive exertional dyspnea and debilitating orthopnea requiring the use of noninvasive mechanical ventilation at night. A review of the literature reveals that neurofibromatosis is an unrecognized cause of diaphragmatic paralysis.- - - - - - - - - - ranking = 1.1666971478417keywords = paralysis, idiopathic (Clic here for more details about this article) |
5/154. Diaphragmatic plication in the extremely low birth weight infant.A case of acquired diaphragmatic paralysis in an extremely low birth weight infant complicated by respiratory failure, recurrent atelectasis, and pneumonia is described. Diaphragmatic plication led to a rapid improvement in pulmonary function and allowed for discontinuation of mechanical ventilation in less than 1 week. Therapeutic options for acquired diaphragmatic paralysis, including the rationale for early operative intervention, in this patient population are discussed.- - - - - - - - - - ranking = 0.33333333333333keywords = paralysis (Clic here for more details about this article) |
6/154. Unilateral diaphragmatic paralysis following bronchial artery embolization for hemoptysis.Bronchial artery embolization is an effective treatment for patients with hemoptysis. Serious complications are rare, but may occur if the arterial supply to other structures is compromised. We present a case of unilateral diaphragmatic paralysis following bronchial artery embolization in a patient with cystic fibrosis. We believe that the diaphragmatic paralysis was due to the inadvertent obstruction of the left pericardiacophrenic artery during the embolization procedure, with compromise of the phrenic nerve blood supply. This resulted in a significant loss of lung function in our patient, who did not recover despite the subsequent return of diaphragmatic function.- - - - - - - - - - ranking = 1keywords = paralysis (Clic here for more details about this article) |
7/154. phrenic nerve injury following blunt trauma.phrenic nerve trauma in the absence of direct injury is unusual and may present diagnostic difficulty. Diaphragmatic paralysis resulting from phrenic nerve injury may closely mimic diaphragmatic rupture. This case highlights the value of magnetic resonance imaging in establishing diaphragmatic integrity and of ultrasonographic assessment during respiratory excursion in confirming diaphragmatic paralysis. In cases of non-contact injury involving torsional injury to the neck, an index of clinical awareness may help to establish the diagnosis of phrenic nerve trauma.- - - - - - - - - - ranking = 0.33333333333333keywords = paralysis (Clic here for more details about this article) |
8/154. Bilateral diaphragmatic paralysis after cardiac surgery: ventilatory assistance by nasal mask continuous positive airway pressure.The case of an 8-month-old boy with bilateral diaphragmatic paralysis after surgical reoperation for congenital heart disease is presented. In order to avoid repeated intubation and long-term mechanical ventilation or tracheotomy, we used nasal mask continuous positive airway pressure (CPAP) as an alternative method for assisted ventilation. Within 24 hours the boy accepted the nasal mask and symptoms such as dyspnea and sweating disappeared. Respiratory movements became regular and oxygen saturation increased. Nasal mask CPAP may serve as an alternative treatment of bilateral diaphragmatic paralysis in infants, thereby avoiding tracheotomy or long-term mechanical ventilation.- - - - - - - - - - ranking = 1keywords = paralysis (Clic here for more details about this article) |
9/154. Diaphragmatic paralysis following cervical chiropractic manipulation: case report and review.This case report documents an uncommon cause of bilateral diaphragmatic paralysis resulting from phrenic nerve injury during cervical chiropractic manipulation. Several months after the initial injury, our patient remains short of breath and has difficulty breathing in the supine position. Other causes of diaphragmatic paralysis and phrenic nerve injury are reviewed.- - - - - - - - - - ranking = 1keywords = paralysis (Clic here for more details about this article) |
10/154. Dysfunction of phrenic pacemakers induced by metallic rescue blankets.Phrenic pacing can restore diaphragmatic contractions in patients with central respiratory paralysis. It relies on radiofrequency transmission of energy from an external unit to implanted receivers through circular coil antennas. The case of a patient is reported in whom severe hypoventilation occurred following the use of a metallic rescue blanket. The phenomenon was confirmed in two subsequent patients and during benchmark tests. Possible mechanisms include reflection and diffusion of high frequency waves by a Faraday-like effect. patients with implanted devices relying on telemetric control or powering, and their care givers, should be warned against the use of metallic rescue sheets.- - - - - - - - - - ranking = 0.16666666666667keywords = paralysis (Clic here for more details about this article) |
