Summary

A patient with mediastinitis experienced right ventricle rupture due to a catheter. Surgical repair under circulatory arrest using a pericardial patch was successful, saving the patient from exsanguinating hemorrhage.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Medical Device Complications

Background:

  • Postoperative mediastinitis presents a significant challenge in thoracic surgery.
  • Chronic indwelling catheters can lead to serious cardiac complications.
  • Mediastinal infections require complex surgical management.

Observation:

  • A 68-year-old male developed mediastinitis post-surgery.
  • A chronic indwelling catheter caused erosion and rupture of the right ventricle anterior wall.
  • The patient suffered near exsanguinating hemorrhage.

Findings:

  • Successful correction of massive hemorrhage was achieved using circulatory arrest.
  • A pericardial patch graft was utilized for the right ventricle repair.

Related Experiment Videos

  • The surgical intervention resulted in favorable patient outcomes.

    • Implications:

    • This case highlights the critical risk of cardiac erosion from indwelling catheters in mediastinitis.
    • Circulatory arrest and pericardial patch repair are effective strategies for managing life-threatening cardiac injuries.
    • Emphasizes the importance of vigilant monitoring for device-related complications in complex thoracic cases.
