Purpose:
To investigate the incidence and patterns of chest compression-associated internal thoracic artery injury (CAI) during cardiopulmonary resuscitation and identify the embolization techniques used to treat hemorrhage.
Materials And Methods:
A retrospective study was conducted in the patients who underwent transcatheter arterial embolization (TAE) for life-threatening hemorrhage caused by CAI at two tertiary care centers between May 2013 and December 2019. Data on background characteristics, imaging findings, embolization and outcomes were collected from the medical records.
Results:
Among 385 patients in whom circulation returned after resuscitation, there were 9 patients (2.3%) who required TAE for CAI. Eight of 9 patients had acute myocardial infarction, and all had been started on extracorporeal membrane oxygenation before TAE. Seven patients had unilateral, and two had bilateral internal thoracic artery injuries. Main trunk injury of internal thoracic artery was seen in 27%, while branch injury in 73%. Six patients (67%) had multiple injuries in the internal thoracic artery territory, and five (56%) had injuries to other vessels. In all cases, we embolized the main trunk of the internal thoracic artery using n-butyl 2-cyanoacrylate and coils (n = 8), a gelatin sponge only (n = 2), or coils and a gelatin sponge (n = 1). TAE was technically successful in all, without any complication. The 30-day mortality rate was 44%.
Conclusions:
CAI needing hemostatic intervention occurred in 2.3% of patients after successful cardiopulmonary resuscitation. Branch injury was more common than main trunk injury, and multiple vessel injuries were common. TAE appears to be safe and effective for controlling life-threatening hemorrhage.
