  • Common trunk of the posterior intercostal arteries from the thoracic aorta [Elektronski vir] : anatomical variation, frequency, and importance in individuals
    Kocbek Šaherl, Lidija ; Rakuša, Mateja
    PURPOSE: A common trunk of the posterior intercostal arteries originating from the descending thoracic aorta is normally an anatomical variation. A search through the literature disclosed the ... frequencies of common trunks variations among population, but no information relates to particular topic of simultaneous multiple common trunks of the PIA present in individuals. METHODS: A total of 396 intercostal spaces were dissected in 44 cadavers from the vertebral body to the mid-axillary line to observe a common trunk of the paired posterior intercostal artery at the level from T2 to T11 intercostal space. RESULTS: In 31 cadavers (70%), a common trunk of posterior intercostal arteries arising from descending thoracic aorta was visualed and 22 of those (71%) had two or more common trunks simultaneously present. CONCLUSIONS: It is important to recognize this anatomical variation when the number of origins of the posterior intercostal arteries from the thoracic aorta due to the multiple common trunk present can be reduced, as their origins and vascular territories are involved in primary diseases of the thoracic aorta, like atherosclerosis, aneurysm, or dissection that lead to serious complications. For example, in thoracoabdominal aneurysm repair, reimplantation of the posterior intercostal arteries is recommended to avoid potential ischemic injury to the supplying areas, especially to the spinal cord.
