Despite advances in endovascular surgery, lower extremity arterial bypass remains the gold standard treatment for severe, symptomatic peripheral arterial disease (PAD). Patients who are transferred to other hospitals have generally complex medical problems compared to those patients who are directly admitted from home. The purpose of this study is to identify factors associated with an interfacility transfer in patients with PAD and compare the postoperative outcomes of these patients to those who are directly admitted to the hospital. ⋯ Multiple factors affect an interfacility transfer of patients including advanced age, need for emergency procedure, contaminated wounds. Patients who are transferred from another institution for a lower extremity bypass surgery are at a substantially higher risk for postoperative morbidity and mortality.

Case Reports
A Rare Entity: Traumatic Thoracic Aortic Injury in a Patient with Aberrant Right Subclavian Artery.
Aberrant right subclavian artery is an uncommon entity incidence ranging from 0.5 to 2.5%. Management of thoracic aortic injury in the presence of such anomalies can be a challenge. We present here a case of traumatic aortic injury, which was incidentally found to have an asymptomatic aberrant right subclavian artery. The patient was managed by an endovascular repair of thoracic aortic injury with an endograft and a right carotid to subclavian artery bypass as a hybrid procedure. ⋯ In a trauma setting with multiple injuries, hybrid procedure with a thoracic endograft is associated with low mortality and morbidity; hence, it is the treatment of choice for thoracic aortic injury over open surgical repair. A hybrid suite can be life and time saving in situations which mandate simultaneous endovascular repair along with surgical revascularization when indicated, especially in cases with aberrant aortic arch anatomy.

Case Reports
Emergency Hybrid Approach to Ruptured Femoral Pseudoaneurysm in HIV-positive Intravenous Drug Abusers.
Chronic traumatism of the common femoral artery due to intravenous injection in drug abusers, in association with local infections and arterial wall weakening caused by human immunodeficiency virus (HIV), can lead to the development of pseudoaneurysms (PSAs). Rupture of PSA is a dramatic event in such patients, and its correction is difficult and controversial. Most of the cases reported describe open surgical elective options, which consist in ligation, repair, or substitution of the damaged arterial segment, using when possible biological grafts. In literature, few cases describe an endovascular repair with covered stent deployment. ⋯ The favorable results and progressive healing of wound and local infections persuaded us not to perform any further surgical correction. The absence of recurrences and late complications, after 3 years in the first case and 1 year in the second one, lead us to consider this hybrid endovascular approach as a valuable alternative to open surgery in HIV intravenous injection in drug abuser patients, in particularly when emergency conditions occur.

These last years, considerable attention has been given to renal issues following endovascular aortic repair but acute kidney injury (AKI) also remains one of the most frequent complications following open repair (OR). Since AKI definition has evolved, our aim was to review the etiology, incidence, classifications, and consequences of AKI after OR for intact abdominal aortic aneurysm (AAA). ⋯ AKI is a common but generally transient complication after OR for AAA. Its incidence depends on definitions used, and few studies were found to use recent consensual AKI criteria. In the future, large prospective studies using consensual AKI definitions will facilitate comparison between repair strategies.

Comparative Study
Mortality Risk for Ruptured Abdominal Aortic Aneurysm in Women.
Sex differences in presentation and outcomes of abdominal aortic aneurysms (AAA) with increased mortality rates in women are suggested. This study aimed to assess mortality risk after repair of ruptured AAA (rAAA) in women in the endovascular abdominal aortic repair (EVAR) era. ⋯ AAA repair is often delayed in women and applied at older age; nevertheless, currently women do not show increased perioperative mortality risks from rAAA treatment after the introduction of EVAR.
