Central Sleep Apnea - a Rare Cause for Acute Respiratory Insufficiency in Children. Case Report.

Central sleep apnea is characterized by frequent cessation of breathing during sleep, resulting in repetitive episodes of insufficient ventilation and abnormalities of acid-base balance. It may be primary or secondary, and it is uncommon in children, with limited data for this population. We present here the case of a five-year-old girl, known to have thoracolumbar myelomeningocele (for which she underwent a surgical procedure in infancy), secondary hydrocephalus (with a ventriculoperitoneal shunt) and flaccid paralysis, who was admitted in our hospital with prolonged fever syndrome, productive cough, severe dyspnea and perioral cyanosis. Following physical examination, laboratory investigations and thoracic radiography, we established the diagnosis of aspiration pneumonia with acute respiratory failure. Medical treatment with multiple systemic antibiotics, antifungal agents, systemic and inhaled bronchodilator, oxygen therapy and respiratory nursing were initiated, with favorable evolution. During the entire hospitalization, the patient showed nocturnal respiratory rhythm disorders, with sleep apnea crisis of approximately 20 seconds and desaturation, followed by severe hypercapnic respiratory acidosis, manifestations that persisted even after the remission of pulmonary infection, raising the suspicion of an apnea syndrome. After excluding the causes of obstructive apnea, a cerebral CT scan was performed, revealing isolated fourth ventricle compressing the brainstem. The patient underwent neurosurgical intervention and postoperatively, the evolution was favorable, with remission of apnea crisis.

Ultrasound Prenatal Diagnosis and Emergency Interventional Radiologic Therapy of Galen Aneurysmal Malformation in a Newborn.

Located under the cerebral hemispheres and draining the anterior and central regions of the brain into the sinus of the posterior cerebral fossa, the vein of Galen aneurysmal malformation is considered to be a rare cause of hydrocephaly. The presence of this condition in the neonatal period typically includes intractable heart failure and a poor prognosis. We report a case of aneurysm of the vein of Galen diagnosed prenatally at 28 weeks of gestation, with the delivery at term by caesarean section of a female infant. Sonographically, the vein of Galen appeared in the mid-sagittal plane, large, supratentorial, non-pulsatile; on color Doppler, the structure filled with bright color, reflecting a turbulent venous flow. A low grade of ventriculomegaly was present during the evolution of pregnancy; regarding the cardiovascular function, an intrauterine right cardiac insufficiency overlapped a tricuspid regurgitation and right atrial dilatation. A multidisciplinary committee decided a neonatal embolization of the aneurysm as an emergency requirement due to increased pulmonary hypertension developed in the next 24 hours after birth. After the embolization of the two main drainage vessels, the cardiac dysfunction persists. Two days later the evolution became unfavorable, leading to the necessity of the second embolization, which resulted in a 48 hours' coma and death, due to a cerebral hemorrhage secondary to thrombosis and fissure of the embolized aneurysm. The prognosis for the neonate with malformation of the Galen vein depends upon the severity of the cardiovascular status. Embolization represents actually the treatment of choice with the best results of these cases, but the mortality remains as high as 50 percent even in the most specialized centers of the world. As far as we know this is the only case of Galen aneurysmal malformation in Romania which beneficiated of embolization by interventional treatment in neonatal period.

Bilateral orbital and optic nerve endoscopic endonasal decompression for nonspecific inflammatory orbital disease: case report.

BACKGROUND: Endoscopic endonasal optic nerve decompression (EEOND) is indicated in traumatic and endocrine orbitopathies as well as in idiopathic intracranial hypertension. CASE: We present a patient with bilateral nonspecific inflammatory orbitopathy (NSIO) and optic nerve compression presenting with acute severe visual loss. Bilateral orbital and optic nerve decompression was performed as an emergency procedure with a favorable ophthalmological result. CONCLUSION: EEOND is an effective and safe technique in acute orbitopathies and should be taken in consideration in atypical clinical settings causing severe acute visual loss.
