A patient with haemoptysis and a smaller right lung

Abstract: A A p pa at ti ie en nt t w wi it th h h ha ae em mo op pt ty ys si is s a an nd d a a s sm ma al ll le er r r ri ig gh ht t l lu un ng g Case historyA 41-year-old businessman was admitted to National Taiwan University Hospital for evaluation of a 2-week history of haemoptysis productive of 50-100 mL of fresh blood daily. The patient stated that haemoptysis had first occurred 10 yrs earlier, had lasted for about 1 month and had spontaneously subsided. Both episodes of haemoptysis were preceded by flu-like symp… Show more

“…A case of right lung hypoplasia with UAPA manifesting as haemoptysis was described in a middle aged male. 1 Another case of pulmonary hypoplasia with RAA along with UAPA was reported in a 21-month-old child. 2 A 5-month child with RAA, right descending aorta and agenesis of the left pulmonary artery has been previously described in literature, 10 presenting with lung infection and progressive respiratory failure.…”

“…4 Warburton et al 5 described an interaction between blood vessels and airways during the development of lung and also highlighted that development of the former controlled airway growth, particularly the formation of alveoli. The possible mechanism for recurrent pulmonary infections in pulmonary hypoplasia may be: (1) reduced blood supply and defective ventilation of the lung parenchyma due to pulmonary artery defect; 6 (2) altered venous pulmonary circulation and (3) extrinsic compression of the large airways by the great vessels. 7 Haemoptysis may occur due to infection in the presence of above predisposing factors or may be due to increased blood flow and pulmonary hypertension in the opposite lung due to UAPA and consequent hypoplasia of the ipsilateral lung.…”

“…Dysphagia may be present when congenital anomalies of the great vessels also lead to extrinsic compression of the oesophagus, such as in the double aortic arch [7]. Haemoptysis may occur due to increased blood flow and pulmonary hypertension in the opposite lung due to unilateral absence of a pulmonary artery with hypoplasia of the ipsilateral lung [10], such as in the case reported here.…”
