Long-term outcomes of carotid endarterectomy vs transfemoral carotid stenting in a Medicare-matched database
Carotid endarterectomy (CEA) is associated with lower risk of perioperative stroke compared with transfemoral carotid artery stenting (TFCAS) in the treatment of carotid artery stenosis. However, there is discrepancy in data regarding long-term outcomes. We aimed to compare long-term outcomes of CEA vs TFCAS using the Medicare-matched Vascular Quality Initiative Vascular Implant Surveillance and Interventional Outcomes Network database.

Angiotensin-converting Enzyme Inhibitors and Angiotensin Receptor Blockers are Associated With Improved Amputation Free Survival in Chronic Limb-threatening Ischemia
In the Heart Outcomes Prevention Evaluation (HOPE) study, investigators found that ramipril was associated with improved survival as well as decreased myocardial infarction (MI) and stroke rates in patients with peripheral arterial disease. Nonetheless, their effect on chronic limb-threatening ischemia (CLTI)-specific outcomes is unclear. We aim to assess the effect of angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACEIs/ARBs) on amputation-free survival in patients with CLTI undergoing peripheral vascular intervention (PVI) in a Medicare-linked database.

Medicare Patients with Symptomatic Carotid Disease Requiring Carotid Revascularization Are Likely to Have Delayed Access: An Analysis of a Multicenter Surgical Data
The Society for Vascular Surgery clinical practice guidelines for management of extracranial cerebrovascular disease recommends carotid revascularization as soon as the patient is neurologically stable after 48  hours and before 14 days of symptom onset in patients with recent stroke. In the United States, insurance status has been demonstrated to play a role in wait times for surgical care. There are no large-scale studies that assess the effect of patient primary insurance status on time to surgery in patients with symptomatic carotid disease.

One-Year Outcomes of Transcarotid Artery Revascularization Versus Transfemoral Carotid Artery Stenting in a Medicare Database
Transfemoral carotid artery stenting (TFCAS) was introduced as a minimally invasive option for high-risk patients not eligible for carotid endarterectomy. However, TFCAS was found to be associated with higher rates of perioperative stroke. This was attributed to the unprotected manipulation of the aortic arch and carotid atherosclerotic lesion. Therefore, transcarotid artery revascularization (TCAR) was introduced as a hybrid alternative to TFCAS. Prior studies have shown a significantly lower risk of perioperative stroke and death compared with TFCAS.

A Comparative Analysis of Outcomes After Carotid Artery Stenting in the Vascular Quality Initiative Versus Medicare Using the Vascular Quality Initiative –Medicare-Matched Dataset
Current evidence suggests a lower risk of perioperative stroke or death after transcarotid artery revascularization (TCAR) compared with transfemoral carotid artery stenting (tfCAS); however, data on longer term outcomes are limited. Clinical registries linked with administrative data such as Medicare offer opportunities for the assessment of long-term outcomes. We used the Vascular Quality Initiative (VQI) –Medicare-matched dataset to compare the postoperative outcomes identified in the VQI vs Medicare for patients who underwent TCAR or tfCAS.

One-year Outcomes of Transcarotid Artery Revascularization vs Carotid Endarterectomy in Medicare Database
Carotid endarterectomy (CEA) has played a major part in reducing stroke in patients with significant carotid artery stenosis. Transcarotid artery revascularization (TCAR) was introduced as a minimally invasive hybrid procedure to treat patients who are considered anatomically and/or medically high risk for CEA. Prior studies reported no differences in perioperative stroke/death between TCAR and CEA. However, data regarding 1-year outcomes of TCAR vs CEA are scarce, and all prior studies had only about 50% follow up at 1  year.

Rules of engagement: The delicate dance between vascular surgeons, industrial partners, and patient outcomes
In 1953, Michael E. DeBakey performed the first carotid endarterectomy successfully. It would be almost 60  years until a new technique disrupted the carotid world with as much furor. In 2012, transcarotid artery revascularization (TCAR) burst onto the scene. With its minimally invasive, hybrid appeal and equivalency to carotid endarterectomy stroke risk, TCAR quickly won the hearts of many vascular sur geons. The update of TCAR technology was rapid, increasing dramatically at 15% annually, with a real jolt coming in 2016 when the Centers for Medicare& Medicaid Services allowed coverage for TCAR under the existing nationa...

Expansion of Transcarotid Artery Revascularization to Standard Risk Patients for Treatment of Carotid Artery Stenosis
Transcarotid artery revascularization (TCAR) is currently reimbursed by the Centers for Medicare and Medicaid Services for treatment of medically and anatomically high-risk patients. TCAR has been found to be associated with equivalent stroke/death outcomes compared with carotid endarterectomy (CEA) for high-risk patients. However, the safety profile of TCAR in standard-risk patients is currently not well-defined and has limited its expansion of use in this patient population.

Delayed Carotid Endarterectomy After Admission in Symptomatic Carotid Artery Disease Is Associated With Lower Postoperative Stroke Rates in the Medicare Population
The appropriate timing of carotid endarterectomy (CEA) in symptomatic carotid artery disease is still controversial. Despite guideline recommendations to perform CEA within 14 days, recent studies have favored delayed CEA to decrease the risk of postoperative stroke. The goal of this study was to evaluate the timing of CEA for symptomatic disease in the Medicare population and its effects on postoperative stroke rates.

IP131. Transfemoral Carotid Angioplasty and Stenting With Embolic Protection: A 7-year Retrospective Analysis of a Single-Center Experience
Carotid angioplasty and stenting (CAS) is an excellent, often superior, alternative to carotid endarterectomy (CEA). When performed by experienced operators, both are equivalent in periprocedural risk and stroke prevention. Widespread adoption of CAS in the United States has been impeded by reimbursement regulations mandated by the Centers for Medicare and Medicaid Services (CMS) that favor CEA over CAS for patients with asymptomatic carotid disease. This policy has led to decreased CAS volumes and an increase in percentages of patients receiving CAS for symptomatic vs asymptomatic disease.

Impact of amputation level and comorbidities on functional status of nursing home residents after lower extremity amputation
Conclusions: Elderly nursing home residents undergoing BK or AK amputation failed to return to their functional baseline within 6 months. Among frail elderly nursing home residents, higher amputation level, stroke, end-stage renal disease, poor baseline cognitive scores, and female sex were associated with inferior functional status after amputation. These factors should be strongly assessed to maintain activities of daily living and quality of life in the nursing home population.

The current national criteria for carotid artery stenting overestimate its efficacy in patients who are symptomatic and at high risk
In this study, we stratified patients who underwent CAS or CEA by CMS high-risk criteria and symptom status and examined their 30-day outcomes.Methods: A nonrandomized, retrospective cohort study was performed by chart review of all patients undergoing CEA or CAS from January 1, 2005, to December 31, 2010, at our institution. Demographic data and data pertaining to the presence or absence of high-risk factors were collected. Patients were stratified using symptom status and high-risk status as variables, and 30-day adverse events (stroke, death, myocardial infarction [MI]) were compared.Results: A total of 271 patients und...

Accuracy of administrative data versus clinical data to evaluate carotid endarterectomy and carotid stenting
Conclusions: Administrative data are unreliable for determining symptom status, high-risk status, and perioperative stroke and should not be used to analyze CEA and CAS. NSQIP data do not adequately identify high-risk patients, but do accurately identify perioperative strokes and to a lesser degree, symptom status.
