An initially dry pericardial window in a 34-year-old male with transmediastinal gunshot wounds did not prevent delayed cardiac tamponade requiring emergency surgical exploration on postoperative day 6.
Case Report (n=1)
A dry pericardial window in transmediastinal gunshot wound trauma does not rule out significant underlying cardiac injuries, and delayed cardiac tamponade can still occur.
Delayed cardiac tamponade following a dry pericardial window in trauma patients, particularly those with transmediastinal gunshot wounds (TMGSW), is extremely rare and presents a significant diagnostic challenge. This report presents the case of a 34-year-old male with multiple gunshot wounds to the thorax and abdomen who initially presented with a dry pericardial window and a stable post-operative course. Unexpectedly, by the third postoperative day, the patient developed acute pericarditis. This was followed by neurologic decline, severe hemodynamic instability, and a large pericardial effusion consistent with cardiac tamponade by postoperative day six. Emergency surgical exploration revealed approximately 500 mL of bloody fluid within the pericardial sac. This case highlights that the presence of a dry pericardial window in TMGSW trauma does not rule out the possibility of significant underlying cardiac injuries. It emphasizes the need for vigilant monitoring, routine imaging, and consideration of early drainage techniques to prevent delayed complications. Additionally, recognizing that delayed cardiac tamponade may manifest subtly, including with neurological symptoms, is essential for improving outcomes in high-risk trauma cases.
Huang et al. (Wed,) conducted a case report in Delayed cardiac tamponade (n=1). Emergency surgical exploration was evaluated. An initially dry pericardial window in a 34-year-old male with transmediastinal gunshot wounds did not prevent delayed cardiac tamponade requiring emergency surgical exploration on postoperative day 6.
