ABSTRACT Background: High flow arteriovenous malformation (AVM) of the mandible is rare, but it can present as a life-threatening emergency with severe intraoral bleeding for the first time. The gold standard of treatment for an AVM of the mandible is selective embolisation combined with resection and subsequent reconstructions. With the advent of advanced multidisciplinary techniques aimed at definitive therapy, surgical resection and primary reconstruction can provide an ideal anatomical and functional cure. There are no previous reports on primary resection and reconstruction for life-threatening haemorrhage from high flow AVM of the mandible. Aim: We discuss our approach aimed at definitive therapy in life-threatening intraoral bleeding from large high flow AVM of the mandible. Subjects and Methods: Four patients were managed for life-threatening intraoral bleeding during 2015–2017. Compression was applied over the bleeding point before the airway could be secured by endotracheal tube. Under general anaesthesia, the external carotid artery (ECA) was temporarily occluded using an umbilical tape loop ligature to control the bleeding. Emergency selective embolisation was done, followed by curative resection and primary mandible reconstruction using free fibula flap. Outcome assessed. Results: Temporary occlusion of the ECA successfully controlled the bleeding immediately and facilitated selective embolisation and definitive therapy. All the four cases were successfully reconstructed with a good outcome. There was no recurrence during the follow-up period. Conclusion: In life-threatening intraoral bleeding from large high flow AVM of the mandible, emergency selective embolisation followed by curative resection and primary reconstruction is safe in achieving an ideal cure.

ABSTRACTArteriovenous malformations (AVMs) are uncommon errors of vascular morphogenesis; haemodynamically, they are high-flow lesions. Approximately 50% of AVMs are located in the craniofacial region. Subtotal excision or proximal ligation of the feeding vessel frequently results in rapid progression of the AVMs. Hence, the correct treatment consists of highly selective embolisation (super-selective) followed by complete resection 24-48 hours later. We treated 20 patients with facial arteriovenous malformation by using this method. Most of the lesions (80%) were located within the cheek and lip. There were no procedure related complications and cosmetic results were excellent.

Until recently the prime purposes of filters have been to produce clear filtrates or to collect particles from solution and then remove the filter medium and examine the particles by transmission electron microscopy. These filters have not had the best characteristics for scanning electron microscopy due to the size of the pores or the surface topography. Advances in polymer chemistry and membrane technology resulted in membranes whose characteristics make them versatile substrates for many scanning electron microscope applications. These polysulphone type membranes are anisotropic, consisting of a very thin (0.1 to 1.5 μm) dense skin of extremely fine, controlled pore texture upon a much thicker (50 to 250μm), spongy layer of the same polymer. Apparent pore diameters can be controlled in the range of 10 to 40 A. The high flow ultrafilters which we are describing have a surface porosity in the range of 15 to 25 angstrom units (0.0015-0.0025μm).

Purpose Infants hospitalized for an acute respiratory illness often require the use of noninvasive respiratory support during the initial stage to improve their breathing. High flow oxygen therapy (HFOT) is becoming a more popular means of noninvasive respiratory support, often used to treat respiratory syncytial virus/bronchiolitis. These infants present with tachypnea and coughing, resulting in difficulties in coordinating sucking and swallowing. However, they are often allowed to feed orally despite having high respiratory rate, increased work of breathing and on HFOT, placing them at risk for aspiration. Feeding therapists who work with these infants have raised concerns that HFOT creates an additional risk factor for swallowing dysfunction, especially with infants who have compromised airways or other comorbidities. There is emerging literature concluding changes in pharyngeal pressures with HFOT, as well as aspiration in preterm neonates who are on nasal continuous positive airway pressure. However, there is no existing research exploring the effect of HFOT on swallowing in infants with acute respiratory illness. This discussion will present findings from literature on HFOT, oral feeding in the acutely ill infant population, and present clinical practice guidelines for safe feeding during critical care admission for acute respiratory illness. Conclusion Guidelines for safety of oral feeds for infants with acute respiratory illness on HFOT do not exist. However, providers and parents continue to want to provide oral feeds despite clinical signs of respiratory distress and coughing. To address this challenge, we initiated a process change to use clinical bedside evaluation and a “cross-systems approach” to provide recommendations for safer oral feeds while on HFOT as the infant is recovering from illness. Use of standardized feeding evaluation and protocol have improved consistency of practice within our department. However, further research is still necessary to develop clinical practice guidelines for safe oral feeding for infants on HFOT.
