Delayed Pulmonary Artery Stump Thrombosis Presenting With Haemoptysis: A Rare Presentation of a Rare Phenomenon.

Pulmonary artery stump thrombosis (PAST) is a complication following lobectomy and pneumonectomy where a thrombus is formed at the site of the pulmonary stump. It remains a rare condition, but the clinical significance is debatable. Delayed presentation of PAST is very rare. Most cases are incidental and are treated as benign. However, here we report a very rare case of PAST presenting as haemoptysis and associated with pulmonary hypertension.
