TREATMENT OF THE POST-TRAUMATIC TYPE B AORTIC DISSECTION IN A TEENAGER: A CLINICAL CASE

Post-traumatic aortic dissection is one of the most dangerous, life-threatening clinical conditions that is rarely encountered in pediatric clinical practice. The article represents a case of post-traumatic aortic dissection in a teenager. A 14 years old male patient, M., had been admitted to the pediatric clinic of the Saint Petersburg State Pediatric Medical University (Saint Petersburg, Russia) on Dec. 29, 2020, with a preliminary diagnosis as follows: car accident injury, post-traumatic injury of the thoracic aorta with the formation of a true aneurysm in the initial section of the descending thoracic aorta. During the examination, the diagnosis was clarified towards post-traumatic type B aortic dissection. The damages to the ascending aorta and aortic arch were excluded. Within 48 hours after admission a single-stage hybrid surgical intervention was performed using advanced diagnostic algorithms in the form of 3D printing, as well as combined surgical treatment, which included endovascular intervention with previous carotid-subclavian bypass grafting, resulting in positive immediate and long-term clinical outcomes. The active surgical tactics minimized the likelihood of life-threatening complications that could affect the outcome of treatment in the observed case.
