Summary

Post-traumatic myocardial infarction is a well-known although rare complication of blunt chest traumas. In cases of proximally located damage to the coronary arteries, modern vascular surgery such as bypass operations may be lifesaving. In this paper we describe a case, where a healthy 35-year-old man developed a lethal myocardial infarction 8 days after a chest trauma caused by a moped. The ECG obtained 4 h after the accident showed extensive transmural ischemia of the anterior wall. At autopsy a hematoma originating from a side branch was found to compress the left anterior descending coronary artery immediately distal to its origin from the main stem. This finding suggests that bypass surgery could have saved the life of this young man. Patients with evidence of myocardial ischemia following chest traumas should be transferred to a cardiac center as early as possible.

Zusammenfassung

Der post-traumatische Myokardinfarkt ist eine gut bekannte, wenn auch seltene Komplikation nach stumpfem Thorax-Trauma. Bei einer Lokalisation des Schadens im Bereich der proximalen Koronararterien kann die moderne Gefäßchirurgie, wie z. B. Bypass-Operationen, lebensrettend sein. Wir beschreiben einen Fall, bei welchem ein gesunder, 35 Jahre alter Mann 8 Tage nach einem Brustkorbtrauma durch Moped-Unfall einen tödlichen Myokardinfarkt erlitt. Ein bereits 4 Stunden nach dem Unfall aufgenommenes EKG zeigte eine extensive transmurale Ischämie der Vorderwand. Bei der Obduktion wurde ein von einem Seitenast ausgehendes Hämatom gefunden, welches den Ramus interventricularis anterior unmittelbar nach seinem Ursprung komprimierte. Dieser Befund läßt daran denken, daß eine Bypass-Operation das Leben dieses jungen Mannes hätte retten können. Patienten mit Zeichen des Myokardinfarkts nach Brustkorbtrauma sollten so bald als möglich in ein Herzzentrum transportiert werden.
