A rare case of intercostal-to-pulmonary artery fistula and its endovascular treatment in the setting of post pulmonary tuberculosis bronchiectasis and haemoptysis.

Intercostal artery-to-pulmonary artery fistula is an extremely rare variant of systemic artery-to-pulmonary artery fistulas (SA-PAFs). A case of a 38-year-old man presenting with clinically significant haemoptysis secondary to an intercostal artery-to-pulmonary artery fistula in the setting of post-pulmonary tuberculosis (TB) bronchiectasis is described. The fistulae were successfully treated with endovascular coils.ContributionThis case report illustrates an intercostal artery-to-pulmonary artery fistula associated with post-primary tuberculosis bronchiectasis, highlighting its multimodal radiological features and successful endovascular treatment.
