Abstract:

Amyloidosis is a term that involves a group of diseases characterised by deposition of extracellular monoclonal light - chain fibrillar immunoglobulin aggregates in the body , including many organs , with the larynx among them . A case is presented of a 78 year - old man who was referred to our institution for strangulated umbilical hernia treatment . He suffered from progressive hoarseness and dysphagia for 5months . He had a history of primary laryngeal amyloidosis . Awake intubation was performed successful with the King Vision® video - laryngoscopy . Sedation was achieved using a remifentanil infusion and midazolam . Haemorrhagic lesions are caused by deposition of amyloid in and around vessels , resulting in increased vascular fragility . Therefore , anaesthetists should take care in intubating the tracheas of these patients .
