Endovascular repair (EVAR) has been increasingly used for ruptured abdominal aortic aneurysms (rAAAs), especially in major academic centers. The goal of this article is to report our results with an EVAR-first approach for rAAA which we adopted in 2001 in our community hospital. ⋯ Our results show that EVAR is feasible with favorable outcomes in patients presenting with rAAA in a busy community hospital. There is a high secondary intervention rate, which can potentially be decreased by ensuring good iliac limb anatomy at the end of the procedure and by a closer follow-up.

Comparative Study
Outcomes of surgical and endovascular treatment of acute traumatic thoracic aortic injury.
Acute thoracic aortic injury resulting from blunt trauma is a life-threatening condition. Endovascular therapy is a less invasive treatment modality that may potentially improve patient outcomes. We reviewed our experience with patients who sustained blunt thoracic aortic injuries distal to the left subclavian artery and presented for open surgical or endovascular repair. ⋯ Endovascular repair of blunt descending thoracic aortic injuries utilizing thoracic or abdominal endographs is a technically feasible modality that is at least equivalent to open therapy in the short term and associated with a lower intraoperative mortality (P = .056). Endovascular therapy has advantages in operative time, operative blood loss, and intraoperative blood transfusions.

Technical proficiency in carotid artery stent (CAS) procedures is paramount to ensure patient safety. If virtual reality (VR) simulation is to be used as a valid means for credentialing physicians for CAS procedures, the assessment parameters must be able to evaluate the performance during CAS and to differentiate level of CAS experience. The aim of this study was to validate assessment parameters of a commercially available VR simulator (VIST, Vascular Interventional Surgical Trainer, Mentice, Gothenburg, Sweden) during a CAS procedure in experienced interventionalists. ⋯ Total time and fluoroscopic time both recorded by a realistic VR simulator differentiate between levels of CAS experience in experienced interventionalists. Error scoring is currently not a valid mode of assessment and needs refinement.

Endovascular management of acute blunt traumatic thoracic aortic injury: a single center experience.
Traumatic injury of the thoracic aorta is a life-threatening complication in patients who sustain deceleration or crush injuries. The magnitude of force necessary to cause blunt thoracic aortic injury results in a high proportion of concomitant injuries, posing a significant challenge for prioritizing management. Open surgical mortality is increased in the presence of coexisting head, lung, and abdominal injuries. Spinal cord ischemia may occur following aortic cross-clamping and operative hypotension. Endovascular stent-graft placement offers a safe, effective, and timely treatment option. The aim of this study was to assess our single center experience of endovascular repair following acute blunt traumatic aortic injury. ⋯ Endovascular repair is evolving as the procedure of choice for acute blunt traumatic aortic injury. Treatment of lesions that extend into the aortic arch is feasible with extra-anatomical bypass. In our study, endovascular repair of blunt traumatic aortic injury is a safe procedure with low morbidity and a mortality rate of zero.

Acute procedurally induced hemodynamic depression can occur after carotid angioplasty and stenting (CAS). This study was performed to determine the frequency and risk factors for hypotension and bradycardia after the CAS procedure. ⋯ Hemodynamic depression, including hypotension and bradycardia, is frequent after CAS. However, CAS-induced hemodynamic depression is rare in patients with postendarterectomy stenosis. Patients with compromised ejection fraction and increased age are at a higher risk of presenting with CAS-induced hemodynamic instability, and persistent hypotension after CAS is associated with an increased postprocedural complication rate.
