Curved Nitinol Stent-Graft Placement for Treating Blunt Thoracic Aortic Injury: An Early Experience

Iliac Leg and Abdominal Aortic Cuff Stent-Graft for Blunt Thoracic Aortic Injury in Young Patient

“…These factors may lead to difficulty in finding appropriate stent-graft size, higher risk of migration, endoleak, device fracture and collapse, or iliac artery avulsions. 1,4,6,8) Another challenge is the frequently unavoidable left subclavian artery coverage to get adequate proximal landing zone. However, several studies demonstrated the safety of its coverage if there are patent of Circle of Willis and normal right vertebral artery.…”

“…1,2,4,9) Operative repair is associated with high morbidity and mortality. 1) Patients with major associated injuries could be safely managed with delayed repair under effective blood pressure control.…”

“…1,2,4,9) Operative repair is associated with high morbidity and mortality. 1) Patients with major associated injuries could be safely managed with delayed repair under effective blood pressure control. 9) Early repair should be considered only for patients with brain injury who need a higher mean arterial pressure, 5,7) presenting with hypotension, and aortic arch hematoma >15 mm; 10) our case demonstrated all of these findings.…”

“…1,2) Immediate surgical repair is often difficult due to concomitant injuries. Thoracic endovascular aortic repair (TEVAR) has recently evolved as the first treatment option.…”

In situ bending of thoracic stent grafts: Clinical application of a novel technique to improve conformance to the aortic arch

“…[7][8][9][10] The anatomic and procedural factors that may be associated with stent graft collapse include small aortic diameter, gross stent graft oversizing, emergency treatment for aortic transsection, and the presence of a so-called gothic arch. 8,[11][12][13] The systolic jet that hits the outer aspect of a protruding stent graft may also cause excessive pulsatile motion of the proximal stent. Metal fatigue may develop rapidly, with subsequent stent fracture and stent graft collapse.…”
