We report the case of a woman in her 60s with symptomatic complete heart block, who developed symptoms of respiratory distress following the PPI procedure. Radiological investigations revealed a large mediastinal haematoma. An iatrogenic venous injury must have caused its development. Conservative management led to gradual improvement of symptoms and resolution of haematoma. The patient remained normal on follow-ups. This case underscores the importance of prompt recognition and management of this complication. Mediastinal haematoma following venous injuries has a good prognosis with conservative treatment. Clinicians should be vigilant for this rare complication to ensure timely intervention and favourable outcomes.<\/jats:p>","DOI":"10.1136\/bcr-2024-263152","type":"journal-article","created":{"date-parts":[[2024,12,26]],"date-time":"2024-12-26T03:45:23Z","timestamp":1735184723000},"page":"e263152","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":0,"title":["Mediastinal
