Zusammenfassung
Der Zufallsbefund eines Aneurysmas des rechten Sinus Valsalvae bei einem 45 Jahre alt gewordenen Mann, der sich mit einem Spanngurt in typischer Weise erhängt hatte, wird vorgestellt. Bei der Obduktion zeigte sich innerhalb des rechten Sinus Valsalvae eine 2×1,5 cm messende Aussackung. Hierin fanden sich ein verkalktes Atherombeet und eine schlitzförmige Verengung des Abgangs der rechten Herzkranzarterie. Herzspitzennah in der Hinterwand fand sich eine 4×5 cm messende Herzmuskelschwiele bei einem Rechtsversorgungstyp. Die histologische Untersuchung der Aneurysmawand zeigte eine Fragmentation und den Verlust elastischer Fasern sowie eine Atrophie und fibröse Umwandlung der glatten Muskulatur.
Abstract
The case of an aneurysm of the right coronary artery coincidentally discovered in a 45-year-old man who died of a typical suicide attempt is reported. The autopsy revealed a 2x1.5 cm outpouching inside the Valsalva sinus of the right coronary artery with a calcified atheroma bed. Examination of the root of right coronary artery showed narrowing of the artery at the junction with the aneurismal sac, otherwise the coronary artery was unremarkable. In the posterior wall of the right ventricle adjacent to the apex of the heart, a scar measuring 4×5 cm was present due to a myocardial infarction. The histological examination of the aneurysm wall showed fragmentation, loss of elastic fibers and atrophy and fibrous changes of the medial layer.
