Insights
A multidisciplinary board for carotid artery stenting (CAS) is feasible and beneficial. This approach improves patient care through oversight, standardization, and collaboration, reducing complications and enhancing outcomes.
Area of Science:
- Vascular Surgery
- Interventional Neurology
- Cardiology
Background:
- Assessed the feasibility of a mandated multidisciplinary carotid revascularization board (MDCB).
- The MDCB aims to review, approve, and monitor all carotid artery stenting (CAS) procedures and outcomes.
- Ensures appropriate CAS referral through evidence-based consensus.
Purpose of the Study:
- To evaluate the feasibility and advantages of a mandated MDCB.
- To establish a model for accountable care in carotid revascularization.
- To improve institutional oversight and standardize CAS procedures.
Main Methods:
- Established a board comprising vascular surgeons, cardiologists, interventional neuroradiologists, neurosurgeons, and neurologists.
- Conducted weekly meetings for evidence-based consensus recommendations.
- Reviewed and approved all CAS procedures at the institution.
Main Results:
- The MDCB successfully reviewed and approved all CAS procedures.
- For 69 high-risk patients (mean age 70.5, 79% stenosis), periprocedural complications included 2.7% death, 2.7% major stroke, 2.7% minor stroke, and 2.7% MI.
- At 1 year, ipsilateral stroke was 8.1% and neurovascular death was 2.7%. At 21 months, all-cause mortality was 18.8% and stroke incidence was 14.5%.
Conclusions:
- A mandated MDCB is feasible and advantageous in clinical practice.
- The MDCB provides institutional oversight, operator credentialing, and quality review.
- This model promotes standardized care, cost containment, and collaborative practice.
Background:
We tested the feasibility of a mandated multidisciplinary carotid revascularization board (MDCB) to review, approve and monitor all carotid artery and stenting (CAS) procedures and outcomes at our institution.
Methods:
The board was composed of vascular surgeons, cardiologists, interventional neuroradiologists, neurosurgeons, and neurologists, who met weekly to facilitate an evidence-based, consensus recommendation to ensure appropriate CAS referral.
Results:
The board successfully reviewed and continues to review and approve all CAS procedures at our center. Of the 69 patients considered high risk for standard surgical treatment, 42 patients were symptomatic and 27 patients were asymptomatic. Their mean age was 70.5-year-old and the median degree of stenosis was 79%. In the 74 procedures, periprocedural complications occurred at the following rates: 2.7% death, 2.7% major stroke, 2.7% minor stroke, and 2.7% myocardial infarction (MI) within 30 days of the procedure. At 1 year the primary endpoints of ipsilateral stroke and neurovascular-related death were observed in 8.1% and 2.7% of the patients, respectively. At mean follow-up of 21 months, 18.8% of the patients (13/69) had died (including all causes), and 14.5% (10/69) experienced stroke (including nontarget strokes). Target vessel revascularization was needed in 2.9% patients.
Conclusions:
A mandated multidisciplinary carotid revascularization board MDCB is feasible and potentially advantageous in real clinical practice. It establishes a model for accountable care by providing a mechanism for institutional oversight, credentialing operators, quality review, standardizing care, cost containment and eliminating the "subspecialty silo mentality."
