Article Synopsis
- In October 2023, the Centers for Medicare & Medicaid Services agreed to reconsider its national coverage determination for carotid artery stenting (CAS), prompting discussions about its potential impact on patient care.
- Supporters of expanding the CAS coverage cite findings from multiple large studies indicating similar outcomes between CAS and carotid endarterectomy, while opponents express concerns over increased stroke risks, higher healthcare costs, and premature decision-making without validated tools for patient guidance.
- The expansion may risk burdening asymptomatic and standard-risk patients with unnecessary complications, suggesting that financial incentives might drive the procedure's adoption rather than actual patient benefits.
Objective: While ambulatory capacity is a readily assessable clinical indicator of functional status, its association with outcomes after endovascular aneurysm repair (EVAR) remains underexplored. This study aimed to investigate the association between pre-operative ambulatory status and outcomes following elective EVAR.
Methods: A retrospective review of the multi-institutional Vascular Quality Initiative database was conducted for all patients who underwent elective infrarenal EVAR from 2009 - 2022.
Objective: The infrageniculate popliteal artery is a potential source for inflow in lower extremity bypass surgery in patients with isolated tibial artery disease. The objective of our study was to assess the short- and long-term outcomes of popliteal-distal bypasses using data from the Vascular Quality Initiative (VQI).
Methods: The VQI registry was queried between 2003 and 2021 for patients undergoing surgical revascularizations with the below-knee popliteal artery serving as inflow.

Article Synopsis
- A thorough pulse examination can effectively assess blood flow to the legs, but modern imaging tests are overshadowing traditional methods in medical training.
- The reliance on advanced imaging techniques may lead to unnecessary expenses and tests for evaluating blood flow issues.
- This report aims to teach newer doctors and remind seasoned ones about the importance of mastering precise pulse examinations in physical assessments.
Objective: Renal transplant is associated with substantial survival advantage in patients with end-stage renal disease. However, little is known about the outcomes of renal transplant recipients (RTRs) after endovascular abdominal aortic aneurysm repair (EVAR). This study aimed to study the effect of renal transplant on perioperative outcomes and long-term survival after elective infrarenal EVAR.

However, little is understood about their effects after aortic repair. The aim of the present study was to evaluate the role of postoperative BB use on the outcomes of thoracic endovascular aortic repair (TEVAR) in TBAD.

- The study aimed to compare the effectiveness of non-reversed (NRGSV) and reversed great saphenous vein (RGSV) bypass techniques for patients undergoing lower limb revascularization using a comprehensive database from 2003 to 2021.
- An analysis of 7,123 patients revealed no significant differences in primary patency (78% for both), secondary patency (90% vs. 89%), or re-intervention rates (16% for both) between the two techniques at one year post-surgery.
- The findings suggest that both RGSV and NRGSV are equally effective, regardless of the type of outflow target or reason
Article Synopsis
- International guidelines recommend using statins, alone or with other medications, to lower LDL cholesterol in patients with asymptomatic or symptomatic carotid stenosis, as it significantly reduces risks of stroke and cardiovascular events.
- The overview evaluates the effectiveness of various lipid-lowering agents, emphasizing that statins and PCSK9 inhibitors offer substantial benefits like stabilizing carotid plaques and lowering stroke rates, while non-statin options like ezetimibe and fibrates also help but to a lesser extent.
- Despite potential side effects, the advantages of lowering LDL cholesterol for these patients outweigh the risks, leading to a recommendation for high-dose statin therapy for all individuals, regardless of their baseline LDL levels.
Article Synopsis
- The study aimed to understand the impact of Renin-angiotensin-system blocking (RASB) agents on the outcomes of patients undergoing carotid artery procedures, focusing on their periprocedural management.
- An analysis of over 150,000 patients who had carotid interventions between 2003 and 2020 revealed that about 52.2% were on RASB agents, with those undergoing carotid endarterectomy (CEA) showing lower rates of periprocedural neurologic events compared to those not on the drugs.
- While RASB treatment seemed to reduce neurologic events in CEA and TCAR procedures, it had no significant effect on events in transfemoral carotid artery stenting (
Article Synopsis
- The study aimed to compare the outcomes of lower extremity bypass (LEB) using in-situ (ISGSV) versus reversed (RGSV) techniques, focusing on primary and secondary patency rates and reintervention needs.
- A total of 8,234 patients were analyzed, with ISGSV showing slightly higher reintervention rates and lower primary patency immediately post-surgery compared to RGSV, although similar secondary patency rates were observed.
- At the one-year mark, ISGSV had a lower rate of reinterventions and comparable primary patency, suggesting it may be associated with a reduced risk of primary patency loss when accounting for confounding factors.
Objective: The carotid artery plaque burden, indirectly measured by the degree of stenosis, quantifies a patient's future embolic risk. In natural history studies, patients with moderate degrees of stenosis have had a lower stroke risk than those with severe stenosis. However, patients with symptomatic carotid stenosis who have experienced transient ischemic attack (TIA) or stroke were found to have both moderate and severe degrees of stenosis.

The number and size of the patent aortic aneurysm sac outflow vessels (ie, the inferior mesenteric, lumbar, and accessory renal arteries) have been implicated as known risk factors for persistent T2Es. Given the technical challenges associated with post-EVAR embolization, prophylactic embolization of aortic aneurysm sac outflow vessels has been advocated to prevent T2Es; however, the evidence available at present is limited.
View Article and Find Full Text PDFObjective: Patients with prior infrarenal aortic intervention represent an increasing demographic of patients undergoing thoracic endovascular aortic repair (TEVAR) and/or complex EVAR. Studies have suggested that prior abdominal aortic surgery is a risk factor for spinal cord ischemia (SCI). However, these results were largely based on single-center experiences with limited multi-institutional and national data that had assessed the clinical outcomes for these patients.

- The study investigates the outcomes of elective chimney endovascular abdominal aortic aneurysm repair (CHEVAR) in asymptomatic patients with degenerative pararenal aortic aneurysms (dPAAs).
- The analysis includes 267 patients treated at 13 centers between 2008 and 2014, with a focus on mortality rates and complications within 30 days post-procedure.
- Results show a 30-day mortality rate of 1.9%, with high rates of technical success and patency, suggesting that CHEVAR is a viable option for managing dPAAs.
