Abdel Rahim A, Elsamani K, Galal AM, Hammoda MI, Mittapalli D. Does the eversion technique have a lower early postoperative stroke rate than the conventional technique in carotid endarterectomy? Ann Med Surg (Lond) 2022; 81:104505. [PMID: 36147067 PMCID: PMC9486758 DOI: 10.1016/j.amsu.2022.104505] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2022] [Revised: 08/20/2022] [Accepted: 08/21/2022] [Indexed: 11/20/2022] Open
Abstract
A best evidence topic has been constructed using a described protocol. The three-part question addressed was: In carotid surgery, Does the eversion technique (ECEA) has an early postoperative lower stroke rate, As compared to conventional carotid endarterectomy (CCEA)? The outcome assessed was the stroke rate in the early potoperative period (30 days) in the two techniques. The best evidence confirmed that there is no statistically significant difference between ECEA and CCEA regarding the early postoperative stroke incidence. Eversion technique and conventional endarterectomy are the main surgical endarterectomy techniques in carotid artery disease. There is no difference between the Eversion and conventional endarterectomy techniques in early postoperative stroke rates. Lack of randomised controlled trials that compare the two techniques.

Abstract
BACKGROUND: Stenosis of the carotid arteries, as a consequence of atherosclerosis is the most common cause of cerebrovascular insult (CVI). Severe (>70%) contralateral stenosis or occlusion (SCSO) of the carotid artery may represent an additional pre-operative risk factor for neurologic incidents.
AIM: The aim of this study was to confirm and compare early perioperative results (0-30 days) of carotid endarterectomy (CEA) in patients with and without SCSO.
PATIENT AND METHODS: In our retrospective-prospective study, we analysed the results of 273 CEA, divided into two groups based on the presence of significant contralateral stenosis or occlusion (non-SCSO and SCSO groups)
RESULTS: 273 CEA’s were performed, divided into two groups: SCSO groups 40 (14.7%) and non-SCSO group 233 (85.3%). Between the two groups, a statistically significant difference between patients was found (54.1% compared to 87.5%; p<0.0005), CEA with patch angioplasty (25.3% compared to 52.5%; p=0.001), and CEA with the use of a shunt (3.9% compared to 35%; p<0.0005) in favour of the SCSO group. There was no statistically significant difference (SCSO was not identified as a risk factor) for any type of stroke or mortality. Logistically regression confirmed SCSO to be an independent predictor of 30-day mortality (OR 21.58; 95% CI 1.27-36.3; p= 0.033) and any type of stroke or mortality (OR 9.27; 95% CI 1.61-53.22; p= 0.012). SCSO was not a predictor of any type of stroke within 30 days. Predictors of any type of stroke was dyslipidemia (OR 0.12, 95% CI 0.02-0.76; p= 0.024).
CONCLUSIONS: There was no statistically significant difference in the incidence of early (30 day) perioperative complications between the analysed groups. The percentage of perioperative complications remains within the accepted parameters, and thus, SCSO should not be qualified as a significant risk factor for CEA. We are of the opinion that CEA remains a safe and acceptable options for patients with SCSO, and SCSO should not be a reason for preferential use of carotid stenting.

Anesthesia Type is Associated with Decreased Cranial Nerve Injury in Carotid Endarterectomy. Ann Vasc Surg 2020; 70:318-325. [PMID: 31917229 DOI: 10.1016/j.avsg.2019.12.033] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2019] [Revised: 09/30/2019] [Accepted: 12/19/2019] [Indexed: 01/30/2023]
Abstract
BACKGROUND Anesthesia modalities for carotid endarterectomy continue to vary nationally. We evaluated and compared short-term outcomes after carotid endarterectomy with general anesthesia (GA) and regional anesthesia (RA) in both symptomatic and asymptomatic patients. METHODS The 2011-2015 American College of Surgeons National Surgical Quality Improvement Program Participant Use Data Files (PUFs) with merged Vascular Procedure-Targeted PUFs for carotid endarterectomy were queried for patients undergoing carotid endarterectomy. Postoperative complications, mortality, and hospital length of stay in patients undergoing GA or RA were compared. RESULTS A total of 14,447 patients were evaluated: 12,389 (85.7%) with GA and 2,058 (14.3%) with RA. The use of GA was inversely associated with patients' age (88.0% in patients aged 22-64 years vs. 83.4% in patients aged ≥80 years, P < 0.0001) and with symptomatic presentation (odds ratio [OR] = 1.25; 95% confidence interval [CI]: 1.13-1.38). There were no differences between GA and RA for in-hospital mortality, 30-day mortality, or postoperative complications of transient ischemic attack, stroke, bleeding, acute renal failure, or restenosis. However, rates of cranial nerve injury were significantly higher in GA than in RA (2.9% vs. 1.7%, respectively; P < 0.002) and confirmed by multivariable analysis (OR = 1.68; 95% CI: 1.19-2.39). Total operative time was also longer for GA than for RA (median: 115 minutes; Interquartile range (IQR): 89-145 versus median: 93 minutes; IQR: 76-119, respectively; P < 0.0001). Hospital length of stay was greater in GA than in RA (median: 1 day; IQR 1-2 vs. median: 1 day; IQR 1-1, respectively; P < 0.0001), as were 30-day readmission rates (6.7% vs. 5.4%, respectively; P = 0.02). CONCLUSIONS Iatrogenic nerve injury is a feared complication of carotid endarterectomy, especially in elective asymptomatic patients. RA reduces the rate of cranial nerve injury compared with GA. RA is also not inferior to GA for postoperative complications with the benefit of shorter operative times, lengths of hospital stay, and decreased 30-day readmission rates. Consideration should be given to more widespread adoption of this underused anesthesia modality.

Abstract
AIM The study was aimed at comparing the results of eversion carotid endarterectomy and carotid endarterectomy with patch plasty in the immediate and remote postoperative periods. MATERIALS AND METHODS The literature was retrieved by means of electronic databases, with the dates of publications ranging from 1970 to 2019. According to the inclusion and exclusion criteria we selected the literature making it possible to carry out a meta-analysis in the immediate and remote postoperative periods. The results were obtained with the help of the Stata 14 software package. Eventually, we retrieved and analysed a total of 2139 articles. Of these, ten were included into the study and contained 3568 patients subjected to 3672 operations (eversion carotid endarterectomy - 1718 and carotid endarterectomy with a patch - 1954). The results of the meta-analysis were as follows: the mean time of carotid artery cross-clamping for eversion carotid endarterectomy was shorter than that for carotid endarterectomy with a patch (4.1±2.9 min); the frequency of using intraoperative temporary bypass in eversion carotid endarterectomy turned out to be significantly less compared with carotid endarterectomy with patch plasty - 13.5% (91/672) and 62.0% (492/793), OR=0.183, 95% CI: 0.136-0.254, p<0.001; the incidence rate of ischaemic stroke in the immediate and remote postoperative periods was significantly lower after eversion carotid endarterectomy than that after carotid endarterectomy with patch plasty - OR=0.452, 95% CI: 0258-0.792, p=0.005 and OR=0.300, 95% CI; 0.155-0.579, p=0.000. The development of restenosis in the immediate and remote postoperative periods was observed less often for eversion carotid endarterectomy compared with carotid endarterectomy with patch plasty - OR=0.604, 95% CI: 0.422-0.864, p=0.006. CONCLUSION Eversion carotid endarterectomy was associated with shorter time of carotid artery cross-clamping, lower frequency of intraoperative temporary bypass, lower number of cases of ischaemic stroke in the immediate and remote postoperative periods, as well as those of restenosis in the long-term postoperative period.

Abstract
Background and Purpose- This analysis was performed to assess the association between perioperative and clinical variables and the 30-day risk of stroke or death after carotid endarterectomy for symptomatic carotid stenosis. Methods- Individual patient-level data from the 5 largest randomized controlled carotid trials were pooled in the Carotid Stenosis Trialists' Collaboration database. A total of 4181 patients who received carotid endarterectomy for symptomatic stenosis per protocol were included. Determinants of outcome included carotid endarterectomy technique, type of anesthesia, intraoperative neurophysiological monitoring, shunting, antiplatelet medication, and clinical variables. Stroke or death within 30 days after carotid endarterectomy was the primary outcome. Adjusted risk ratios (aRRs) were estimated in multilevel multivariable analyses using a Poisson regression model. Results- Mean age was 69.5±9.2 years (70.7% men). The 30-day stroke or death rate was 4.3%. In the multivariable regression analysis, local anesthesia was associated with a lower primary outcome rate (versus general anesthesia; aRR, 0.70 [95% CI, 0.50-0.99]). Shunting (aRR, 1.43 [95% CI, 1.05-1.95]), a contralateral high-grade carotid stenosis or occlusion (aRR, 1.58 [95% CI, 1.02-2.47]), and a more severe neurological deficit (mRS, 3-5 versus 0-2: aRR, 2.51 [95% CI, 1.30-4.83]) were associated with higher primary outcome rates. None of the other characteristics were significantly associated with the perioperative stroke or death risk. Conclusions- The current results indicate lower perioperative stroke or death rates in patients operated upon under local anesthesia, whereas a more severe neurological deficit and a contralateral high-grade carotid stenosis or occlusion were identified as potential risk factors. Despite a possible selection bias and patients not having been randomized, these findings might be useful to guide surgeons and anesthetists when treating patients with symptomatic carotid disease.

Editor's Choice - Overview of Primary and Secondary Analyses From 20 Randomised Controlled Trials Comparing Carotid Artery Stenting With Carotid Endarterectomy. Eur J Vasc Endovasc Surg 2019; 58:479-493. [PMID: 31492510 DOI: 10.1016/j.ejvs.2019.06.003] [Citation(s) in RCA: 46] [Impact Index Per Article: 9.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2018] [Revised: 05/30/2019] [Accepted: 06/05/2019] [Indexed: 12/19/2022]
Abstract
OBJECTIVES The aim of this review was to carry out primary and secondary analyses of 20 randomised controlled trials (RCTs) comparing carotid endarterectomy (CEA) with carotid artery stenting (CAS). METHODS A systematic review and meta-analysis of data from 20 RCTs (126 publications) was carried out. RESULTS Compared with CEA, the 30 day death/stroke rate was significantly higher after CAS in seven RCTs involving 3467 asymptomatic patients (odds ratio [OR] 1.64, 95% confidence interval [CI] 1.02-2.64) and in 10 RCTs involving 5797 symptomatic patients (OR 1.71, 95% CI 1.38-2.11). Excluding procedural risks, late ipsilateral stroke was about 4% at 9 years for both CEA and CAS, i.e., CAS was durable. Reducing procedural death/stroke after CAS may be achieved through better case selection, e.g., performing CEA in (i) symptomatic patients aged > 70 years; (ii) interventions within 14 days of symptom onset; and (iii) situations where stroke risk after CAS is predicted to be higher (segmental/remote plaques, plaque length > 13 mm, heavy burden of white matter lesions [WMLs], where two or more stents might be needed). New WMLs were significantly more common after CAS (52% vs. 17%) and were associated with higher rates of late stroke/transient ischaemic attack (23% vs. 9%), but there was no evidence that new WMLs predisposed towards late cognitive impairment. Restenoses were more common after CAS (10%) but did not increase late ipsilateral stroke. Restenoses (70%-99%) after CEA were associated with a small but significant increase in late ipsilateral stroke (OR 3.87, 95% CI 1.96-7.67; p < .001). CONCLUSIONS CAS confers higher rates of 30 day death/stroke than CEA. After 30 days, ipsilateral stroke is virtually identical for CEA and CAS. Key issues to be resolved include the following: (i) Will newer stent technologies and improved cerebral protection allow CAS to be performed < 14 days after symptom onset with risks similar to CEA? (ii) What is the optimal volume of CAS procedures to maintain competency? (iii) How to deliver better risk factor control and best medical treatment? (iv) Is there a role for CEA/CAS in preventing/reversing cognitive impairment?

Abstract
OBJECTIVE Patch angioplasty during carotid endarterectomy is commonly used to treat symptomatic and asymptomatic carotid artery stenosis. The objective of the present study was to compare the different patch materials that are currently available (synthetic vs venous vs bovine pericardium) in terms of short- and long-term outcomes. METHODS This study was performed according to the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines and eligible randomized control trials were identified through a comprehensive search of PubMed, Scopus, and Cochrane Central published until September 2017. A meta-analysis was conducted with the use of a random effects model. The I2 statistic was used to assess for heterogeneity. The primary study end point was the incidence of long-term restenosis. Secondary study end points were 30-day stroke, transient ischemic attack (TIA), myocardial infarction, neck wound infection, local hematoma, carotid artery thrombosis, cranial nerve injury, long-term stroke incidence, and death. RESULTS Eighteen studies and 3234 patients were included. The risk of 30-day stroke (relative risk [RR], 1.00; 95% confidence interval [CI], 0.45-2.19; I2 = 0%), TIA (RR, 1.14; 95% CI, 0.41-3.19; I2 = 0%), myocardial infarction (odds ratio, 0.75; 95% CI, 0.14-3.97; I2 = 0%), death (RR, 0.53; 95% CI, 0.21-1.34; I2 = 0%), wound infection (RR, 1.84; 95% CI, 0.43-7.81; I2 = 0%), carotid artery thrombosis (RR, 1.47; 95% CI, 0.44-4.97; I2 = 0%), cranial nerve palsy (RR, 1.21; 95% CI, 0.53-2.77; I2 = 0%), and long-term stroke (RR, 2.33; 95% CI, 0.76-7.10; I2 = 0%), death (RR, 1.09; 95% CI, 0.65-1.83; I2 = 0%) and restenosis of greater than 50% (RR, 0.48; 95% CI, 0.19-1.20; I2 = 0%) were similar between the synthetic vs venous patch groups. Also, no differences in terms of 30-day stroke (RR, 0.31; 95% CI, 0.02-5.16; I2 = 63.1%), TIA (RR, 0.49; 95% CI, 0.14-1.76; I2 = 0%), death (RR, 0.74; 95% CI, 0.05-10.51; I2 = 31.7%), carotid artery thrombosis (RR, 0.13; 95% CI, 0.02-1.07; I2 = 0%), and long-term restenosis of greater than 70% (RR, 0.15; 95% CI, 0.01-2.29; I2 = 70.9%) were detected between the synthetic polytetrafluoroethylene and Dacron patch groups. The comparison between the bovine pericardium vs synthetic patch did not yield any statistically significant results in terms of 30-day stroke (RR, 1.44; 95% CI, 0.19-10.79; I2 = 12.7%), TIA (RR, 1.05; 95% CI, 0.11-10.27; I2 = 0%), local neck hematoma (RR, 4.01; 95% CI, 0.46-34.85; I2 = 0%), and death (RR, 4.01; 95% CI, 0.46-34.85; I2 = 0%). CONCLUSIONS Closure of the carotid arteriotomy with any of the studied patch materials seems to be similar in terms of short- and long-term end points. However, additional randomized trials with adequate follow-up periods are needed to compare bovine pericardium patches with other patch materials.

Abstract
INTRODUCTION Atherosclerosis blood vessels, be it on extra-cranial or intra-cranial circulation, the most common cause of incidents such as cerebro-vascular insult (ICV). Carotid endarterectomy (CEA) is a preventive operation to reduce the risk of stroke and it can be performed by eversion carotid endarterectomy (E-CEA) or a classical carotid endarterectomy (C-CEA). The aim of this study was to investigate the influence of the used techniques in basic perioperative results and the incidence of postoperative complications. MATERIALS AND METHODS It was retrospective-prospective study that involved 173 patients, with carotid stenosis, who underwent CEA, in the period of time December 2013 till December 2016. Subjects were divided into two groups in respect of technique: 90 patients were treated with E-CEA and 83 patients were treated with C-CEA. RESULTS Between two groups revealed a significant difference in favor of the patients from group E-CEA in the length of the surgery (92.56 ± 29.11 min. vs. 104.04 ± 18.01 min., P = 0.000), the time of clamping the carotid arteries (11.83 ± 1.81 min. vs. 23.69 ± 5:39 min., p = 0.000), the amount of post-operative drainage (25.33 ± 24.67 ml. vs. 36.14 ± 14:32 ml., p = 0.001), time spent in the intensive care unit (± 25.43 vs. 13:51 hours 34.54 ± 35.81 hours, p = 0.000), and the length of stay (4.60 ± 0.90 days vs. 5:42 ± 1.80 days, p = 0.001). In the patients of the group E-CEA, fewer number of individual postoperative complications without statistical significance: ICV (2.2% vs. 4.8%, p = 0.351), cardiac arrhythmia (2.2% vs. 4.8%, p = 0.351), transitory ischaemic attack (TIA) and cognitive disorder (2.2% vs. 7.2%, p = 0.117), mortality (1.1% vs. 1.2%, p = 0.954); and the total number of postoperative complications was significantly less in the same patients (7.77% vs. 18.7%, p = 0.042). CONCLUSION The results of this study clearly indicate that operating techniques affects the specified monitored outcomes of vascular treatment of carotid arteries in favor of E-CEA technique. It would be ideally that the conclusions of this study contribute to broader use of E-CEA in treatment of carotid stenosis.

Abstract
OBJECTIVE Prior studies have suggested a relationship between operative (Op) time and outcome after major vascular procedures. This study analyzed factors associated with Op time and outcome after carotid endarterectomy (CEA) in the Vascular Quality Initiative (VQI) registry. METHODS Elective, primary CEAs without high anatomic risk or concomitant procedures from 2012 to 2015 in the VQI were analyzed (N = 26,327, performed by 1188 surgeons from 249 centers). Multivariable analysis was used to identify patient, procedure, and surgeon factors associated with Op time and major adverse events (MAEs), categorized as either technical (ipsilateral stroke, cranial nerve injury, reoperation) or cardiac (myocardial infarction, congestive heart failure, dysrhythmia requiring treatment, surgical site infection, and death). RESULTS The mean CEA Op time in the VQI was 114 minutes, with the mean Op time for individual surgeons ranging from 37 to 305 minutes. Procedural factors and the surgeon's volume were responsible for much of the variation in overall Op time (patient factors that reflected demographics and comorbidities each added 5.9 to 6.8 minutes; procedural factors, such as patch angioplasty and completion duplex ultrasound, each added 5.5 to 16.4 minutes; the lowest quartile of the surgeon's annual case volume added 24 minutes). Chi-pie analysis demonstrated that patient factors accounted for 17% of variability in Op time; procedural factors, 44%; and the surgeon's annual volume, 39%. Increasing Op time was highly associated with increased rates of MAEs (P < .001 for cardiac, technical, and death rates). Based on hierarchical multiple logistic regression, cardiac complications were independently associated with increased Op time (comparing surgeons in highest quartile of Op time with those in the lowest: odds ratio, 2.16 for cardiac MAE; 95% confidence interval, 1.59-2.95; P < .001) but not with the surgeon's annual volume. Technical complications were independently associated with a surgeon's low volume (comparing surgeons with the highest annual case volume by quartile against the lowest: odds ratio, 1.25 for technical MAE; 95% confidence interval, 1.06-1.48; P < .001) but not with Op time. CONCLUSIONS Op time for elective, primary CEAs varies substantially across surgeons in the VQI. Increased Op time is associated with a surgeon's lower annual CEA volume in addition to patient variables and techniques employed. Cardiac complications after CEA are associated with longer Op time, whereas technical complications are associated with a surgeon's low annual volume.

Abstract
Little is known about changes in carotid plaque morphology during aging and the possible impact on cardiovascular events. Only few studies addressed so far age-related modifications within atherosclerotic lesions. Therefore, in this work we endeavored to summarize the current knowledge about changing of plaque composition in elderly. The data from hitherto existing studies confirm that atherosclerotic plaques undergo distinct alternations with advanced age. However, the results are often ambiguous and the changes do not seem to be as disastrous as expected. Interestingly, none of the studies could definitely evidence increased plaque vulnerability with advanced age. Nevertheless, based on the previous work showing decrease in elastin fibers, fibroatheroma, SMCs, overall cellularity and increase in the area of lipid core, hemorrhage, and calcification, the plaque morphology appears to transform toward unstable plaques. Otherwise, even if inflammatory cells often accumulate in plaques of younger patients, their amount is reduced in the older age and so far no clear association has been observed between thin fibrous cap and aging. Thus, the accurate contribution of age-related changes in plaque morphology to cardiovascular events has yet to be elucidated. KEY MESSAGES Composition of carotid atherosclerotic lesions changes during aging. These alternations are however, just moderate and depend upon additional variables, such as life style, accompanying disease, genetics, and other factors that have yet to be determined. Based on the current data, the age-associated plaque morphology seems to transform toward vulnerable plaques. However, the changes do not seem to be as disastrous as expected.

Abstract
Purpose: To compare postoperative morphological and rheological conditions after eversion carotid endarterectomy versus conventional carotid endarterectomy using computational fluid dynamics. Basic methods: Hemodynamic metrics (velocity, wall shear stress, time-averaged wall shear stress and temporal gradient wall shear stress) in the carotid arteries were simulated in one patient after conventional carotid endarterectomy and one patient after eversion carotid endarterectomy by computational fluid dynamics analysis based on patient specific data. Principal findings: Systolic peak of the eversion carotid endarterectomy model showed a gradually decreased pressure along the stream path, the conventional carotid endarterectomy model revealed high pressure (about 180 Pa) at the carotid bulb. Regions of low wall shear stress in the conventional carotid endarterectomy model were much larger than that in the eversion carotid endarterectomy model and with lower time-averaged wall shear stress values (conventional carotid endarterectomy: 0.03–5.46 Pa vs. eversion carotid endarterectomy: 0.12–5.22 Pa). Conclusions: Computational fluid dynamics after conventional carotid endarterectomy and eversion carotid endarterectomy disclosed differences in hemodynamic patterns. Larger studies are necessary to assess whether these differences are consistent and might explain different rates of restenosis in both techniques.

Abstract
Purpose Comparative results of conventional carotid endarterectomy (cCEA) and eversion carotid endarterectomy (eCEA) have been reported in many studies. But in Korea, there have been no reports to compare the outcome of the two techniques. Thus, we investigated the results of eCEA compared to cCEA in Yeungnam University Medical Center. Methods A total of 120 subjects who underwent CEA were included in this study. Of them, cCEAs were performed in 63 patients and eCEAs were performed in 57 patients. We analyzed the results divided into the early (within 30 days after surgery), midterm (from 30 days up to 1 year after surgery) and late (over 1 year after surgery). Results Mean age of the patients was 65.9 ± 7.1 years in cCEA group and 66.8 ± 7.7 years in eCEA group (P = 0.523). Carotid shunt frequency was higher in the cCEA group (39.7% vs. 19.3%, P = 0.015). There were no statistical differences in the early complications with the exception of a significantly higher risk for new brain lesions in the cCEA group (34.9% vs. 14.0%, P = 0.008). The frequency of complication was same between cCEA group and eCEA group in the midterm. Although there was no statistical significance, the frequency of late complications was higher in the cCEA group compared to eCEA group. Mean follow-up duration was 29.4 ± 23.5 months. Conclusion These data showed that eCEA was an acceptable procedure and had some advantage compared to cCEA in the aspect of the early and late complication.

Abstract
OBJECTIVE Carotid endarterectomy (CEA) remains the gold standard for treating carotid disease in selected symptomatic and asymptomatic patients, though carotid angioplasty and stenting has emerged as a safe alternative. The aim of this study was to assess the durability of CEA in a large series of patients followed up according to a strict clinical and ultrasonographic protocol. METHODS Over a 23-year period (1990-2012) a total of 1773 patients (1251 men and 522 women) with a mean age of 75.2 years (range, 31 to 96 years) who underwent 2007 consecutive primary eversion CEAs performed by the same surgeon under general anesthesia with electroencephalographic monitoring and selective shunting were prospectively followed up with ultrasonography at 1, 6, and 12 months, then yearly. A long-term follow-up (median, 11.2 years; mean, 12.9 years) was obtained for 1680 patients (94.8%). End points were perioperative (30-day) stroke and death and late carotid restenosis/occlusion rates. RESULTS More than two in three of the lesions (1446 of 2007, 72.1%) were symptomatic at the time of surgery, with a 25% rate of preoperative stroke. Preoperative antiplatelet or anticoagulant therapy was used by 1675 patients (94.4%), whereas 918 (51.8%) were receiving statin treatment. Overall, there were eight (0.4%) perioperative strokes and no deaths. During the follow-up, there were nine (0.47%) asymptomatic late carotid restenoses (six moderate [50%-69%] and three severe [≥ 70%]) and one (0.05%) carotid occlusion. Nine patients (0.47%) had late ipsilateral strokes, none of them related to restenosis/occlusion. Overall, there were 159 late deaths (9.4%). CONCLUSIONS The results of this study show that eversion CEA can be performed in symptomatic and asymptomatic patients with an extremely low perioperative stroke/death risk and a negligible incidence of late restenosis/occlusion, thus assuring a persistently good protection against the risk of cerebral ischemia.

Abstract
Stenosis of the extracranial carotid artery is a treatable cause of ischemic stroke and can reliably be detected and graded by vascular ultrasound. The differentiation between symptomatic and asymptomatic stenosis, the perioperative risk and the estimated life expectancy of the patient guide the therapy. Therapy is based on an optimal treatment of cardiovascular risk factors and antiplatelet drugs. Revascularization using surgical carotid endarterectomy is efficient for the prevention of stroke in patients with a high grade symptomatic stenosis. Endovascular therapy using stent-protected angioplasty of the carotid artery is an alternative in patients with a higher surgical risk with low complication rates when performed in experienced centres. Patients with asymptomatic carotid artery stenosis are primarily treated conservatively and revascularization is indicated in patients with a low surgical and global cardiovascular risk.

Abstract
BACKGROUND Safe and complete surgical excision of carotid plaque in carotid endarterectomy (CEA) is essential for preventing postoperative embolic stroke and restenosis. We considered the dissection plane for the plaque according to pathological findings of carotid atherosclerosis. We report our experiences with inner-intimal dissection in CEA. METHODS To obtain complete resection of the plaque with a smooth distal edge and bloodless surface by minimal exposure of the media, the thickened intima was sliced under high-magnification microscopy. The excised specimens were examined pathologically. RESULTS Sixty-three CEAs were performed for 61 patients with carotid stenosis. Complete resection without tacking suture was obtained in all procedures. No mortality was encountered. Minor stroke was recorded in 1 procedure (1.6%). No early restenosis was recorded during follow-up (range, 1-35 months; mean, 15.6 months). Pathological examination revealed interintimal excision of the lesion in each case. CONCLUSION Microsurgical interintimal dissection could accomplish good surgical outcome, including absence of significant early restenosis.
