Abstract: A right pulmonary artery originating from the ascending aorta was first reported by Fraentzel in 1868.' Including our own, only six cases of this anomaly have been described in adults.'The condition is more often recognised early in life, because the large left to right shunt rapidly leads to biventricular failure.369Patients living beyond infancy experience frequent respiratory complaints, such as dyspnoea on exertion, episodic wheezing, and frequent airway infections."'Later haemoptysis will overshadow these symptoms.Haemoptysis first occurred in the age range 15-23 years in the reported cases.2It characteristically follows exertion and the expectorated blood varies from minor amounts to as much as 200 ml.The true nature ofthe cause of bleeding is usually not apparent from physical examination or review of standard chest radiographs.Adults with this malformation are thus likely to undergo bronchoscopy for recurrent haemoptysis.The importance of this is well illustrated by the following case.
