Despite an increase in the incidence of hospital admissions for comorbid conditions, such as diabetes, the incidence of major limb amputation in North Carolina has decreased. The decline in amputation rate has not been uniformly realized across the state. The objective of this study was to determine the association between major vascular limb amputation and living in an underserved county in North Carolina. ⋯ Living in an underserved county in North Carolina is associated with a 29% increase in the odds of undergoing major limb amputation. Gender, age, and comorbidities, including diabetes, end-stage renal disease, and PAD, do not significantly affect the relationship.

Comparative Study
Comparative effectiveness of endovascular versus open repair of ruptured abdominal aortic aneurysm in the Medicare population.
Endovascular aortic repair (EVAR) for abdominal aortic aneurysm (AAA) is increasingly used for emergent treatment of ruptured AAA (rAAA). We sought to compare the perioperative and long-term mortality, procedure-related complications, and rates of reintervention of EVAR vs open aortic repair of rAAA in Medicare beneficiaries. ⋯ EVAR for rAAA is associated with lower perioperative and long-term mortality in Medicare beneficiaries. Increasing adoption of EVAR for rAAA is associated with an overall decrease in mortality of patients hospitalized for rAAA during the last decade.

Comparative Study
Comparison of renal perfusion solutions during thoracoabdominal aortic aneurysm repair.
To determine whether renal perfusion with cold crystalloid solution enriched with histidine-tryptophan-ketoglutarate (Custodiol; Dr Franz-Kohler Chemie GmbH, Bensheim, Germany) provides better protection against renal ischemic injury than cold lactated Ringer's solution in patients undergoing thoracoabdominal aortic aneurysm open repair. ⋯ The use of Custodiol was safe and provided improved perioperative renal function compared with lactated Ringer's solution. Randomized trials are needed to confirm these data and to assess their clinical consequences.

An 87-year-old man sustained an intracerebral hemorrhage in the watershed area of the contralateral frontal lobe immediately after carotid artery stenting (CAS) for severe cervical internal carotid artery (ICA) stenosis. The contralateral cervical ICA was occluded. ⋯ This case demonstrates that CAS in patients with contralateral ICA occlusion and insufficient collateral flow can cause dramatically increased collateral flow through the circle of Willis and result in contralateral hyperperfusion. In patients with severely compromised cerebral perfusion, measures should be taken to prevent hyperperfusion-related complications.

This study evaluated the safety and effectiveness of the Zenith Dissection Endovascular System (Cook Medical, Bloomington, Ind) in the urgent treatment of acute type B aortic dissections complicated by organ malperfusion. ⋯ Used as a treatment for organ malperfusion complicating acute type B dissections, the Zenith Dissection Endovascular System achieved safely and effectively satisfactory clinical results in the short term. The long-term effect of this composite treatment on aortic remodelling remains to be determined.
