J Vasc Surg 2023; 77:1424-1433.e1. [PMID: 36681256 PMCID: PMC10353412 DOI: 10.1016/j.jvs.2023.01.015] [Citation(s) in RCA: 5] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/23/2022] [Revised: 12/31/2022] [Accepted: 01/10/2023] [Indexed: 01/19/2023]
Abstract
OBJECTIVE Optimal temporal surgical management of significant carotid stenosis and coronary artery disease remains unknown. Carotid endarterectomy (CEA) and coronary artery bypass (CABG) are performed concurrently (CCAB) or in a staged (CEA-CABG or CABG-CEA) approach. Using the Vascular Quality Initiative-Vascular Implant Surveillance and Interventional Outcomes Coordinated Registry Network-Medicare-linked dataset, this study compared operative and long-term outcomes after CCAB and staged approaches. METHODS The Vascular Quality Initiative-Vascular Implant Surveillance and Interventional Outcomes Coordinated Registry Network dataset was used to identify CEAs from 2011 to 2018 with combined CABG or CABG within 45 days preceding or after CEA. Patients were stratified based on concurrent or staged approach. Primary outcomes were stroke, myocardial infarction (MI), all-cause mortality, stroke and death as composite (SD) and all as composite within 30 days from the last procedure as well as in the long term. Univariate analysis and risk-adjusted analysis using inverse propensity weighting were performed. Kaplan-Meier curves of stroke, MI, and death were created and compared. RESULTS There were 1058 patients included: 643 CCAB and 415 staged (309 CEA-CABG and 106 CABG-CEA). Compared with staged patients, those undergoing CCAB had a higher preoperative rate of congestive heart failure (24.8% vs 18.4%; P = .01) and decreased renal function (14.9% vs 8.5%; P < .01), as well as fewer prior neurological events (23.5% vs 31.4%; P < .01). Patients undergoing CCAB had similar weighted rate of 30-day stroke (4.6% vs 4.1%; P = .72), death (7.0% vs 5.0%; P = .32), and composite outcomes (stroke and death, 9.8% vs 8.5%; P = .56; stroke, death, and MI, 14.7% vs 17.4%; P = .31), but a lower weighted rate of MI (5.5% vs 11.5%; P < .01) vs the staged cohort. Long-term adjusted risks of stroke (hazard ratio [HR], 0.85; 95% confidence interval [CI], 0.54-1.36; P = .51) and mortality (HR, 1.02; 95% CI, 0.76-1.36; P=.91) were similar between groups, but higher risk of MI long-term was seen in those staged (HR, 1.49; 95% CI, 1.07-2.08; P = .02). CONCLUSIONS In patients undergoing CCAB or staged open revascularization for carotid stenosis and coronary artery disease, the staged approach had an increased risk of postoperative cardiac event, but the short- and long-term rates of stroke and mortality seem to be comparable. Adverse cardiovascular event risk is high between operations when staged and should be a consideration when selecting an approach. Although factors leading to staged sequencing performance need further clarity, CCAB seems to be safe and should be considered an equally reasonable option.

AbuRahma AF, Darling RC. Literature review of primary versus patching versus eversion as carotid endarterectomy closure. J Vasc Surg 2021; 74:666-675. [PMID: 33862187 DOI: 10.1016/j.jvs.2021.02.051] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2020] [Accepted: 02/19/2021] [Indexed: 11/25/2022]
Abstract
BACKGROUND Which type of closure after carotid endarterectomy (CEA), whether primary, patching, or eversion, will provide the optimal results has remained controversial. In the present study, we compared the results of randomized controlled trials (RCTs) and systematic meta-analyses of the various types of closure. METHODS We conducted a PubMed literature review search to find studies that had compared CEA with primary closure, CEA with patching, and/or eversion CEA (ECEA) during the previous three decades with an emphasis on RCTs, previously reported systematic meta-analyses, large multicenter observational studies (Vascular Quality Initiative data), and recent single-center large studies. RESULTS The results from RCTs comparing primary patching vs primary closure were as follows. Most of the randomized trials showed CEA with patching was superior to CEA with primary closure in lowering the perioperative stroke rates, stroke and death rates, carotid thrombosis rates, and late restenosis rates. These studies also showed no significant differences between the preferential use of several patch materials, including synthetic patches (polyethylene terephthalate [Dacron; DuPont, Wilmington, Del], Acuseal [Gore Medical, Flagstaff, Ariz], polytetrafluoroethylene, or pericardial patches) and vein patches (saphenous or jugular). The results from observational studies comparing patching vs primary closure were as follows. The Vascular Study Group of New England data showed that the use of patching increased from 71% to 91% (P < .001). Also, the 1-year restenosis and occlusion (P < .01) and 1-year stroke and transient ischemic attack (P < .03) rates were significantly lower statistically with patch closure. The results from the RCTs comparing ECEA vs conventional CEA (CCEA) were as follows. Several RCTs that had compared ECEA with CCEA showed equivalency of CCEA vs ECEA (level 1 evidence) with patching in the perioperative carotid thrombosis and stroke rates. At 4 years after treatment, the incidence of carotid stenosis was lower for ECEA than for primary closure (3.6% vs 9.2%; P = .01) but was comparable between patching and eversion (1.5% for patching vs 2.8% for eversion). CONCLUSIONS Routine carotid patching or ECEA was superior to primary closure (level 1 evidence). We found no significant differences between the preferential use of several patch materials. The rates of significant post-CEA stenosis for CEA with patching was similar to that with ECEA, and both were superior to primary closure.

Abstract
BACKGROUND Previous reports of extracellular matrix (ECM) patch use after carotid endarterectomy (CEA) have noted an approximately 10% rate of pseudoaneurysm (PSA) formation. PSA-related rupture of ECM patches has also been described after femoral artery repair. In these studies, different thicknesses (4-ply versus 6-ply) and no standard length of soaking the patch in saline before implantation were used. Herein, we describe our experience with ECM CorMatrix patches in 291 CEAs with 6-ply patches. METHODS The records of 275 consecutive patients undergoing 291 CEAs with CorMatrix 6-ply patches beginning in November of 2011 and extending until 2015 were reviewed. Only 6-ply patches and a 1 min hydration time in saline were used in all patients. No shunts were used. RESULTS There were three deaths within the first 30 d secondary to subsequent cardiac surgical procedures. Nine patients experienced a perioperative stroke (3.1%), only one of which occurred secondary to an occluded internal carotid artery. One patient had a transient ischemic attack with a patent endarterectomy site. In follow-up, 11 patients (4.5%) developed severe recurrent stenoses requiring reintervention. Only one patient (0.34%) developed a PSA at 2 years possibly secondary to chronic infection. The median follow-up was 72 mo. CONCLUSIONS Our experience with 6-ply CorMatrix ECM patches and a brief period of soaking demonstrated that these patches performed well in patients requiring a CEA. Only one PSA was noted.

Abstract
OBJECTIVE The management of patients with combined severe carotid artery and coronary artery disease (CAD) is controversial. Transcarotid stenting with flow reversal (TCAR) is a novel hybrid technique for carotid revascularization. We sought to investigate the safety and feasibility of simultaneous TCAR and coronary artery bypass grafting (CABG) for concomitant carotid and CAD. METHODS A single-institution, retrospective study of patients with critical carotid artery stenosis and symptomatic CAD who underwent simultaneous TCAR-CABG was completed. The primary outcomes were technical success, perioperative stroke, death, and hemorrhage. RESULTS Four patients underwent TCAR-CABG. All patients were male with a mean age of 64. Technical success was achieved in all cases. There were no perioperative strokes or deaths. There were no reexplorations for hemorrhage. CONCLUSIONS Transcarotid stenting with flow reversal-CABG is a technically feasible hybrid approach for simultaneous carotid and coronary revascularization. It should be part of the vascular surgeon's armamentarium for coexisting carotid and coronary disease. Further research focused on patient selection and perioperative antiplatelet management is warranted prior to the widespread adoption of this technique.

Abstract
BACKGROUND Guidelines recommend routine patching after carotid endarterectomy (CEA) on the basis of a lower restenosis rate and presumed lower procedural stroke rate than with primary repair. Underlying evidence is based on studies performed decades ago with perioperative care that significantly differed from current standards. Recent studies raise doubt about routine patching and have suggested that a more selective approach to patch closure (PAC) might be noninferior for procedural safety and long-term stroke prevention. The objective was to review the literature on the procedural safety and perioperative stroke prevention of PAC compared with primary closure (PRC) after CEA. METHODS MEDLINE, Embase, and Cochrane Central Register of Controlled Trials databases were searched from January 1966 to September 2017. Two authors independently performed the search, study selection, assessment of methodologic quality, and data extraction. Articles were eligible if they compared PAC and PRC after CEA, were published in English, included human studies, and had a full text available. Methodologic quality for nonrandomized studies was assessed using the Methodological Index for Non-Randomized Studies score; randomized controlled trials were assessed using Grading of Recommendations Assessment, Development, and Evaluation. Nonrandomized studies with a score ≤15 were excluded. The primary outcome measure was 30-day stroke risk. Secondary outcome measures were long-term restenosis (>50%) and postoperative bleeding. RESULTS Twenty-nine articles met the inclusion criteria, 9 randomized studies and 20 nonrandomized studies, for a total of 12,696 patients and 13,219 CEAs. Overall 30-day stroke risk was higher in the PRC group (odds ratio [OR], 1.9; 95% confidence interval [CI], 1.2-2.9). After exclusion of nonrandomized studies, this difference was not statistically significant anymore (OR, 1.8; 95% CI, 0.8-3.9). The restenosis rate was higher after PRC (OR, 2.2; 95% CI, 1.4-3.4). There were no differences in bleeding complications. Methodologic quality of the nonrandomized studies was moderate, and seven were excluded. Quality of the evidence according to Grading of Recommendations Assessment, Development, and Evaluation was moderate for restenosis, 30-day stroke, and bleeding. CONCLUSIONS In this systematic review, on the basis of moderate-quality evidence, perioperative stroke rate was lower after PAC compared with PRC. The rate of restenosis was higher after PRC, although the clinical significance of this finding in terms of long-term stroke prevention remained unclear.

Abstract
The ideal management of concomitant carotid and coronary artery occlusive disease remains elusive. Although researchers have advocated the potential benefits of varying treatment strategies based on either concomitant or staged surgical treatment, there is no consensus in treatment guidelines among national or international clinical societies. Clinical studies show that coronary artery bypass grafting (CABG) with either staged or synchronous carotid endarterectomy (CEA) is associated with a high procedural stroke or death rate. Recent clinical studies have found carotid artery stenting (CAS) prior to CABG can lead to superior treatment outcomes in asymptomatic patients who are deemed high risk of CEA. With emerging data suggesting favorable outcome of CAS compared to CEA in patients with critical coronary artery disease, physicians must consider these diverging therapeutic options when treating patients with concurrent carotid and coronary disease. This review examines the available clinical data on therapeutic strategies in patients with concomitant carotid and coronary artery disease. A treatment paradigm for considering CAS or CEA as well as CABG and percutaneous coronary intervention is discussed.

Abstract
BACKGROUND AND PURPOSE We evaluated the incidence of perioperative stroke following the institution's 2007 practice change of discontinuing combined carotid endarterectomy and open heart surgery (OHS) for patients with severe carotid stenosis. METHODS In this retrospective cohort study, we compared 113 patients undergoing coronary artery bypass grafting, aortic valve replacement, or both from 2007 to 2011 with data collected from 2001 to 2006 from a similar group of patients. Our aim was to assess whether the practice change led to a greater incidence of stroke. RESULTS A total of 7350 consecutive patients undergoing OHS during the specified time period were screened. Of these, 3030 had OHS between 2007 and 2011 but none were combined with carotid artery surgery (new cohort). The remaining 4320 had OHS before 2007 and 44 had combined procedures (old cohort). Of patients undergoing OHS during the 10-year period of observation, 230 had severe (>80%) carotid stenosis. In the old cohort (before 2007), carotid stenosis was associated with perioperative stroke in 2.5% of cases. None of the 113 patients having cardiac procedures after 2007 received combined carotid artery surgery; only 1 of these patients harboring severe carotid stenosis had an ischemic stroke (.9%) during the perioperative period. The difference in stroke incidence between the 2 cohorts was statistically significant (P = .002). CONCLUSION The incidence of stroke in patients with severe carotid artery stenosis undergoing OHS was lower after combined surgery was discontinued. Combined carotid and OHS itself seems to be an important risk factor for stroke.

Abstract
Carotid endarterectomy (CEA) reduces the risk of stroke in patients with internal carotid artery stenosis, although the optimal surgical technique is debated. The literature suggests that patch angioplasty reduces complication risk, although primary closure shortens cross-clamp time and eliminates complications associated with grafts. The objective of this study was to assess the complication rate after CEA with primary closure. Retrospective review of 240 consecutive patients between 2002 and 2010. Of these patients, 70% returned for follow-up visits for at least 2 or more years. Primary closure was used in all patients. The average cross-clamp time was 18 minutes. Complications in the immediate postoperative period within 30 days were as follows: stroke (n = 3; 1.1%), transient ischemic attack (TIA; n = 4; 1.5%), myocardial infarction (MI; n = 3; 1.1%), and death (n = 1; 0.4%). Short-term follow-up revealed eight patients who were found to have significant restenosis (>80%) by carotid duplex imaging. Two to ten year postoperative complication rates were as follows: stroke (n = 7; 4.2%), TIA (n = 7; 4.2%), amaurosis fugax (n = 1; 0.6%), MI (n = 8; 4.8%), and death (n = 28; 17%). Mortality was due to stroke or heart attack (n = 2; 1.2%), cancer (n = 7; 4.2%), and unknown causes (n = 19; 11%). This study presents our experience with complications after primary closure after CEA. In our experience, CEA is a safe and effective surgical means of preventing stroke in the short term. Well-designed prospective studies are needed to confirm specific patient characteristics in which primary closure and patch angioplasty are indicated.

Abstract
To date, there is increasing clinical need for vascular substitutes due to accidents, malformations, and ischemic diseases. Over the years, many approaches have been developed to solve this problem, starting from autologous native vessels to artificial vascular grafts; unfortunately, none of these have provided the perfect vascular substitute. All have been burdened by various complications, including infection, thrombogenicity, calcification, foreign body reaction, lack of growth potential, late stenosis and occlusion from intimal hyperplasia, and pseudoaneurysm formation. In the last few years, vascular tissue engineering has emerged as one of the most promising approaches for producing mechanically competent vascular substitutes. Nanotechnologies have contributed their part, allowing extraordinarily biostable and biocompatible materials to be developed. Specifically, the use of electrospinning to manufacture conduits able to guarantee a stable flow of biological fluids and guide the formation of a new vessel has revolutionized the concept of the vascular substitute. The electrospinning technique allows extracellular matrix (ECM) to be mimicked with high fidelity, reproducing its porosity and complexity, and providing an environment suitable for cell growth. In the future, a better knowledge of ECM and the manufacture of new materials will allow us to "create" functional biological vessels - the base required to develop organ substitutes and eventually solve the problem of organ failure.

Abstract
The objective of this preliminary study was to develop a reabsorbable vascular patch that did not require in vitro cell or biochemical preconditioning for vascular wall repair. Patches were composed only of hyaluronic acid (HA). Twenty male Wistar rats weighing 250-350 g were used. The abdominal aorta was exposed and isolated. A rectangular breach (1 mm × 5 mm) was made on vessel wall and arterial defect was repaired with HA made patch. Performance was assessed at 1, 2, 4, 8, and 16 weeks after surgery by histology and immunohistochemistry. Extracellular matrix components were evaluated by molecular biological methods. After 16 weeks, the biomaterial was almost completely degraded and replaced by a neoartery wall composed of endothelial cells, smooth muscle cells, collagen, and elastin fibers organized in layers. In conclusion, HA patches provide a provisional three-dimensional support to interact with cells for the control of their function, guiding the spatially and temporally multicellular processes of artery regeneration.

Abstract
OBJECTIVE Management of patients with concomitant carotid and coronary artery disease has been controversial. Divergent strategies have been employed, including simultaneous carotid endarterectomy and coronary bypass (SCC) versus various staged procedures. Although no strict comparison group is available, this study defines current outcomes of SCC, compared qualitatively to two reference categories. METHODS Utilizing the STS database from 2003 to 2007, patients who had SCC were compared with patients with cerebrovascular disease who had coronary bypass (CABG) with prior carotid endarterectomy (CEA), and those with carotid Doppler stenosis >75% and no carotid intervention. Logistic regression analysis adjusted for differences in baseline characteristics and operative mortality (OM), and a composite of neurological complications (NC) was assessed. RESULTS Of 745,769 patients who underwent isolated CABG with/without CEA, 108,212 (14%) had cerebrovascular disease. Of this group, 5,732 (5%) underwent SCC. The SCC group had more males and lower preoperative risk factors. After statistical adjustment for all baseline differences, SCC had clinically and statistically higher OM and NC compared with any of the reference groups, with 20-40% higher event risk. CONCLUSIONS Although no quantitative control group exists for comparison, SCC as recently performed in North America has a high risk compared with any of the reference groups. Suboptimal results associated with the SCC strategy suggest a need for quality improvement and research on the optimal management of patients with simultaneous carotid and coronary disease.

Abstract
Patients with combined carotid and coronary arterial diseases pose a high risk of cerebrovascular events, and the treatment of choice with either a simultaneous or a staged surgical procedure remains controversial. The literature of combined carotid and coronary arterial diseases of a recent decade in English was retrieved. Totally 41,901 patients undergoing simultaneous or staged carotid and coronary procedures from 53 reports were included. As a result, carotid endarterectomy plus coronary artery bypass remained the most commonly used procedure for the intervention of combined carotid artery stenosis and coronary artery disease, and was associated with higher incidences of perioperative transient ischemic attack, stroke and hospital mortality, but with less perioperative myocardial infarction comparing with the staged procedures. Patients with a simultaneous carotid endarterectomy and coronary artery bypass were generally related more to an advanced atherosclerotic coronary artery disease, so that a pure comparison between the two strategies was not always possible. To compare the efficacy of different surgical methods for combined carotid and coronary arterial diseases is of pronounced importance. The new hybrid approach consisting of the simultaneous carotid artery stenting and subsequent on-pump coronary artery bypass can be a safe approach, with the aim to reduce the surgical trauma as compared to surgical procedures, and to reduce the risk of myocardial infarction in the interval period required for the staged operations. Thus, for patients with combined carotid artery stenosis and coronary artery disease, the simultaneous surgical procedure, rather than the staged procedure, is recommended.

Abstract
Patch angioplasty is commonly performed after carotid endarterectomy. Randomized prospective trials and meta-analyses have documented improved rates of perioperative and long-term stroke prevention as well as reduced rates of restenosis for patches compared with primary closure of the arteriotomy. Although use of vein patches is considered to be the gold standard for patch closure, newer generations of synthetic and biologic materials rival outcomes associated with vein patches. Future bioengineered patches are likely to optimize patch performance, both by achieving minimal stroke risk and long-term rates of restenosis as well as by minimizing the risk of unusual complications of prosthetic patches such as infection and pseudoaneurysm formation. In addition, lessons from bioengineered patches will likely enable construction of bioengineered and tissue-engineered bypass grafts.

Abstract
Our objective in this article was to review the most recent literature on the status of carotid patching or primary carotid closure following carotid endarterectomy; to determine the best patch material if needed; and to clarify the place of eversion carotid endarterectomy in management of carotid artery atherosclerosis. In order to accomplish this, a literature review was performed of the Ovid, PubMed and MedLine databases using appropriate search terms. An evidence-based approach was taken; with all articles graded using the Scottish Intercollegiate Guidelines Network system (levels of evidence 1 to 5) and recommendations were made using an A to D system. Most weight was given to well-conducted, adequately powered, randomized control trials. After review of the literature, we were able to make the following Grade A recommendation: carotid patching is superior to primary closure, resulting in fewer postoperative strokes and a lower incidence of restenosis in most surgeons' hands. However, it was also concluded that, based on review of the literature, that the choice of patch material in 2007 has little impact; eversion carotid endarterectomy (CEA) and conventional patch CEA have equivalent postoperative morbidity and similar incidences of long-term restenosis. In conclusion, the technique of CEA continues to evolve, but in most reported series, immediate and long-term outcomes are excellent. A variety of technical approaches are acceptable, but it appears that carotid patching remains superior to primary closure.
