Case Reports
Limitation of imaging in identifying iatrogenic aortic coarctation following thoracic endovascular aortic repair.
A 21-year-old male suffered blunt trauma from a motor vehicle accident causing thoracic aorta tear. The smallest available stent graft was deployed. Definitive repair was later performed using a 22 × 22 × 116 mm Talent Thoracic Stent Graft. ⋯ This case report demonstrates a need for wider availability and selecting appropriate stent graft in treating traumatic aortic injuries in young patients. It is the first case report of the inability of current imaging modalities in confirming stent collapse. Pressure gradient is a useful tool in confirming stent collapse when clinical scenario does not match CT findings.

Blunt traumatic aortic injury (BTAI) is of very rare occurrence in adolescents. The purpose of our study was to assess the clinical presentation and treatment outcomes of BTAI in this subset of patients. ⋯ The incidence of BTAI is very low in adolescents. Mortality rate is considerable even in young patients and it is associated with high ISS and degree of aortic wall disruption. Young patients with BTAI who survive hospitalization have a lower ISS and are often discharged home rather than to a rehabilitation facility.

Controlled limb reperfusion has been shown to prevent the deleterious effects of ischemia-reperfusion (IR) syndrome following revascularization of acute limb ischemia (ALI). To reduce the production of cell-toxic oxygen-free radicals, we have established a new initially oxygen-free, hypothermic, heparin-coated perfusion and hemofiltration system and report on our first results. ⋯ An initially oxygen-free, hypothermic, heparin-coated ECMO counteracts local and systemic effects of IR injury. Reduced mortality and morbidity might result from this new treatment, although this could not be conclusively proven in our study. A prospective, randomized controlled trial is needed to prove superiority of this new concept.
