Dysphagia: A review.

Dysphagia is defined as difficulty in swallowing. It is usually associated either with pharyngeal or oesophagial disease.The Dysphagia lusoria refers to an extraordinary disposition of the subclavian artery (lusorian artery) as a cause of oesophageal obstruction. Although most individuals are asymptomatic, they might present with unspecific thoracic pain, dysphagia, dyspnea, arterioesophageal or arteriotracheal fistulae with hematemesis or hemoptysisThe various embryologic anomalies of the arterialbrachial arch system often remain unrecognised and asymptomatic, but in 30%-40% of cases can result in tracheo-oesophageal symptoms, which in the majority of cases manifest as dysphagia. Diagnosis of dysphagia lusoria is via barium swallow and chest Computed tomography scan. Manometric abnormalities are variable, but age-related manometric changes may contribute to clinically relevant dysphagia lusoria in patients who present later in life.. An aberrant right subclavian artery is the commonest aortic arch anomaly. An aberrant subclavian artery is a rare cause of dysphagia in adults.
