Bleeding from lacerated pleural adhesions is a rare but life-threatening cause of hemothorax following PCI that should be considered in patients with a history of lung disease and severe cough.

Warrants vigilance for pleural adhesion tears in post-PCI hemothorax with lung disease history; single case leaves open incidence and prevention.
An elderly male patient with coronary heart disease underwent coronary angiography, which revealed bilateral severe coronary artery stenosis. Four stents were implanted, and at 5 h post-surgery, typical hemorrhagic shock appeared. Echocardiography verified heavy bleeding in the right thoracic cavity. Emergency angiography excluded injury or perforation of the coronary artery, aorta, right subclavian artery and brachiocephalic artery. Considering the patient's history of chronic obstructive pulmonary disease and severe cough during the operation, it was suspected that hemothorax was induced by a blood vessel rupture in the pleura. Video-assisted thoracic examination confirmed the tearing of pleural adhesion bands and bleeding at three sites in the pulmonary pleura and parietal pleura. According to the reported case, bleeding as a result of the laceration of pleural adhesions is an important cause of hemothorax that should be considered after exclusion of other common causes of pleural hemorrhage.
