RESUMEN
Neurosurgical interventions within the ventral surface of the clivus and upper cervical vertebrae in childhood are sometimes carried out through transoral approach. In this situation, tracheostomy is safer for airway protection and mechanical ventilation compared to prolonged intubation. The world experience of percutaneous dilation tracheostomy in pediatric patients is limited due to anatomical and physiological features, such as difficult orientation in anatomical landmarks, high mobility of the trachea and small tracheal lumen. Also, the trachea easily collapses when pressed in pediatric patients that complicates safe puncture of anterior wall and can lead to perforation of posterior tracheal wall. OBJECTIVE: To describe a modified technique of video-assisted percutaneous dilation tracheostomy using additional thin guide and dilator in children of primary school age. MATERIAL AND METHODS: We considered 11 patients aged 6-12 years who underwent video-assisted percutaneous dilation tracheostomy. RESULTS: There were no perioperative complications (bleeding, false course, perforation of posterior tracheal wall). Infection of tracheostomy, fistulas or tracheal stenosis was absent. CONCLUSION: Percutaneous dilation tracheostomy may be alternative to classical surgical tracheostomy for pediatric patients. Endoscopic control and certain technical changes of percutaneous tracheostomy are necessary and provide safe manipulation. Surgery time, less trauma and minimal cosmetic defect after tracheostomy are significant advantages of this technique compared to surgical tracheostomy.

INTRODUCTION: Paradoxical air embolism (PAE) is a rare potentially fatal complication followed by entering of air emboli from the right cardiac chambers and pulmonary artery to large circulation circle. OBJECTIVE: To analyze five patients who underwent neurosurgical intervention complicated by PAE and early postoperative convulsive syndrome. MATERIAL AND METHODS: There were five patients who developed early postoperative convulsive syndrome after previous neurosurgery in sitting position complicated by PAE. Convulsive syndrome required intensive care at the ICU. MRI confirmed ischemic foci de novo outside the zone of surgical intervention in all cases. All patients underwent video-EEG monitoring in order to select anticonvulsant therapy and evaluate its effectiveness. The authors were able to match the epileptogenic focus in the cerebral cortex with MRI data. Available literature data devoted to the problem of convulsive syndrome after neurosurgery complicated by PAE were analyzed. RESULTS: The focus of epileptiform activity coincided with one of the foci of hyperintense MR signal in all cases. CONCLUSION: Video-EEG monitoring is advisable in patients with impaired consciousness who underwent neurosurgery complicated by PAE.
