Comparative Study
Age-related trends in utilization and outcome of open and endovascular repair for abdominal aortic aneurysm in the United States, 2001-2006.
This study used a large national administrative in-hospital database to compare utilization and age-specific outcomes between open repair (OAR) and endovascular (EVAR) repair for the treatment of abdominal aortic aneurysm (AAA). ⋯ As short-term surgical outcomes are consistently improving for patients undergoing AAA repair, elective EVAR has replaced OAR as the more common method of repair in the United States. The introduction of this technology has been rapidly adopted, particularly for the oldest-old surgical patients, aged >or=85 years, who previously may not have been offered surgical intervention for asymptomatic AAA. Further investigation is necessary to examine whether this trend improves the long-term survival and quality of life for this elderly population.

Comparative Study
Perioperative outcomes and amputation-free survival after lower extremity bypass surgery in California hospitals, 1996-1999, with follow-up through 2004.
There are very few population-based studies of long-term outcomes after lower extremity (LE) bypass graft surgery. This study analyzes perioperative and long-term limb salvage and amputation-free survival outcomes for patients undergoing initial aortoiliac or femoropopliteal bypass graft surgery in California hospitals from 1996 to 1999. ⋯ Long-term outcomes of LE bypass surgery were superior for high-volume hospital patients. Graft surveillance and risk factor follow-up care provide a major opportunity for quality improvement efforts. The contrast between traditional limb salvage and amputation-free survival outcomes raises questions about the value of surgical treatment, particularly for patients with limited life expectancy and without coding of tissue loss or critical limb ischemia.

Endovascular abdominal aortic aneurysm (AAA) repair (EVAR) is associated with a decreased incidence of perioperative cardiac complications compared with open repair. However, EVAR is not associated with long-term survival benefit. This study assessed the effect of perioperative asymptomatic cardiac damage after EVAR on long-term prognosis. ⋯ Asymptomatic cardiac damage in patients undergoing EVAR is associated with poor long-term outcome. Routine perioperative cardiac screening after EVAR might be warranted.

We present a hybrid endovascular approach to a 6.5-cm aneurysm of the right-sided aortic arch with an aberrant left subclavian artery arising from a Kommerell diverticulum, connected to the left pulmonary artery through the ligamentum arteriosum. The two-step procedure consisted of a bilateral carotid-subclavian bypass, followed by an ascending aorta-bicarotid bypass and completed by an endovascular exclusion of the aneurysms by covering the whole aortic arch and its branches. The patient had no complications and is asymptomatic 21 months after surgery. Hybrid procedures may be helpful in complex aortic arch pathologies, reducing complications of challenging open surgery.

Comparative Study
Carotid angioplasty and stenting: treatment of postcarotid endarterectomy restenosis is at least as safe as primary stenosis treatment.
This study compared transcranial Doppler (TCD) imaging and outcomes of carotid angioplasty and stenting (CAS) in stenosis after carotid endarterectomy (CEA) vs primary atherosclerotic stenoses. ⋯ CAS for restenosis after CEA has a complication rate lower than primary CAS. The time interval between CEA and CAS did not influence micro embolic load.
