Background: The role of carotid revascularization in women remains intensely debated because of the lower benefit and higher perioperative risks concerning the male counterpart. After surgery, most people can return to normal activities within three to four weeks. However, although the late crude survival for the asymptomatic cohort was not significantly different from the symptomatic cohort, this in itself was a somewhat unexpected finding. Figure 2. Background and purpose: A limited life expectancy reduces the benefit from carotid endarterectomy (CEA) for treatment of asymptomatic internal carotid artery stenosis. Download figureDownload PowerPointFigure 2. Quality of life after carotid endarterectomy. Key Findings: Analysis of outcomes after carotid endarterectomy (CEA) and carotid artery stenting (CAS) in 473 octogenarians revealed very low 30-day mortality (0.6% vs 0%; P = .18); 5-year survival was 67.6% after CEA and 90.2% after CAS (P < .0001). In total, 5808 patients with a median (range) time at risk of 5.1 (0.1 to 11.8) years, were studied. The average hazard did not differ statistically significantly between the symptomatic and asymptomatic groups (P=0.12; hazard ratio=0.89; 0.76 to 1.03). Long-term survival in the randomized trials is not yet available, in ACAS mean follow-up was 2.6 years and in ACST there is an ongoing long-term follow-up.1,2 These awaited results will probably provide further information on this matter, including the stroke-free survival, which was not possible to assess in this study, because stroke >30 days after surgery is not reported to the Swedvasc. Analyses with Kaplan-Meier curves for survival and relative odds ratio (OR) for predictors of survival were performed.

Numbers of patients at risk listed for every second year of follow-up. Risk factors for 5-year mortality in asymptomatic patients. It is important to bear in mind that these patients represent a highly selected group with often multiple atherosclerotic manifestations that may influence the long-term results. <>stream Adjusted relative odds ratios of 5-year mortality for symptomatic versus asymptomatic patients (adjusted for each of the listed variables one at a time). In this population-based study a substantial reduction in long-term survival was observed. Figure 1. In this study the definition of asymptomatic stenosis excluded all ipsilateral carotid artery events and nonhemispheric symptoms within 6 months (nonhemispheric symptoms including posterior circulation events and nonspecific symptoms). Unauthorized Carotid artery stenting versus endarterectomy for treatment of carotid artery stenosis. It is the only way to remove plaque from the artery. The present review was conducted to describe current published risk scoring systems to predict late mortality after carotid endarterectomy (CEA). Carotid endarterectomy. Age as a Risk Factor Carotid endarterectomy in octogenarians has been studied extensively with both supportive and cautionary conclusions as to its appropriateness and safety. The patients' median age was 69 years (interquartile range [IQR], 10 years); 72% (91) were male, with mRS score of 3 (IQR, 1) and LVCIL volume of 20,000 mm3(IQR, 47,000 mm3). Methods— The Swedish vascular registry (Swedvasc) covers all centers performing CEA. Previous vascular surgery correlated with decreased longevity in this study and was present in 37% of the patients with asymptomatic lesions. endobj The perioperative combined stroke or death rate was 2.2% for the asymptomatic versus 4.4% for symptomatic cohort (P=0.010). In 5177 of 5808 (89.1%) patients the index CEA was for symptomatic and in 631 of 5808 (10.8%) for asymptomatic stenosis. Dashed line represents OR=0.89 (0.76 to 1.03). The circles and lines represent crude relative odds ratios and 95% CIs. To lower his risk of a stroke, his health care provider recommended a procedure to open the blocked carotid artery. This study was supported by a grant from Gorthon Foundation, Helsingborg, Sweden. 2016 Oct 1. Few have examined the dependency of patients and how they perceive their own health changes after surgery. endstream Regression analyses were performed to assess factors influencing long-term survival after CEAs for asymptomatic stenosis, including all patients with 5-year data (ie, patients operated on from January 1994 to November 2000). Although the outcome of carotid endarterectomy is better than that of carotid stenting in patients older than 70 years, the perioperative risk is higher in older patients. Generally, you can go home within 1 to 2 days after a carotid endarterectomy. Stroke is a leading cause of death and a major factor in disability. Prospective data on basic demography and risk factors, together with details of surgical technique and postoperative outcome, are registered. At home. Predictors of decreased longevity were age at operation, diabetes, cardiac disease, and previous vascular surgery. Carotid endarterectomy (or CEA) can be thought of as the “tried and true” surgical treatment for carotid stenosis. Numbers at risk at the beginning of each year and annual mortality after CEA.

This is possible because of the fact that every Swedish citizen has a unique personal identity code. <>>>/BBox[0 0 585 783]/Length 114>>stream Background and Purpose— Large randomized trials have demonstrated a net benefit of carotid endarterectomy (CEA) for asymptomatic carotid artery stenosis compared with best medical treatment. All patients with asymptomatic carotid artery stenosis should be on OMT. Degree of carotid stenosis or status of contralateral ICA are not (yet) reported. stenting and those assigned to endarterectomy with respect to the composite primary end point of periprocedural stroke, myocardial infarction, or death and subsequent ipsilateral stroke. The survival in this population-based study, with half of the patients having had a CEA for an asymptomatic stenosis being dead after 10 years, causes some concerns about the long-term overall benefit of this increasingly performed prophylactic procedure. Large randomized controlled trials have demonstrated a net benefit of CEA in addition to best medical treatment. 7272 Greenville Ave. In a report by AbuRahma et al8 of patients with asymptomatic stenosis (>60%) and contralateral occlusion, the 5-year survival was 83%, and after 10 years was 67%. The problem, of course, is that surgery does not come free–the complication rate ranges from 2-3% in the best of hands. There were 2 fatal strokes (of 3 deaths) among patients operated on for asymptomatic and 19 strokes (of 70 deaths) for symptomatic stenosis. However, it will take years before the follow-up of the trial is completed. In a study on long-term survival after CEA for asymptomatic stenosis, Branchereau et al3 demonstrated survival after 5 years of 74.6%, and after 10 years of 59.4%, when including patients with combined procedures and nonhemispheric symptoms, and when excluding the latter 2 groups the 5-year survival was 82.0%. Research shows that if the paient has NOT had a stroke or a TIA, carotid endarterectomy is generally helpful to reduce stroke risk if … The retrieved Swedvasc data were extensively validated in 4 different procedures, both internal and external. Once you are home, it is important to keep the incision area clean and dry. An analysis of the asymptomatic cohort was performed to evaluate if perioperative complications were predictive of late mortality. But then we learned that the procedure itself can put him at risk for a stroke. Average carotid artery recovery time. Your doctor closed the incision in your neck with stitches.

At baseline, the mean age of the patients was 69 years, and at that age the average life expectancy is 15 years for men and 17 years for women.2 As Patients treated conservatively are not reported to the Registry. Key Words: asymptomatic stenosis carotid endarterectomy long-term survival D uring the past decade carotid endarterectomy (CEA) for asymptomatic stenosis has been the focus for many reports and trials. BMC Cardiovasc Disord. Numbers of patients at risk listed for every second year of follow-up. In a study of CEA with two-thirds having asymptomatic stenosis as indication for the procedure, the long-term survival was similar to the findings of this study, with 72.4% at 5 years and 44.7% at 10 years.6 However, other studies with at least one-third of the patients operated on for an asymptomatic stenosis demonstrated far better survival with 92% to 93% at 5 years and 87% to 89% at 10 years.5,7. If both arteries were asymptomatic or symptomatic, the first operated vessel was defined as the index procedure. Net benefit in future patients will depend on their risks from unoperated carotid lesions (which will be reduced by medication), on future surgical risks (which might differ from those in trials), and on whether life expectancy exceeds 10 years. However, as the baseline risk factors indicate, this is a selected group with many patients (37%) having undergone previous vascular interventions (ie, contralateral CEA, aneurysm repair or interventions for peripheral artery disease [PAD]). I'm scheduled to have a carotid u/s B and an ECHO because I've been diagnosed with carotid artery... of having a carotid endarterectomy? When comparing longevity for patients operated on for other vascular procedures, a published series of revascularization for PAD with claudication a 10-year survival of 54% was demonstrated,16 and for elective repair of an infrarenal aortic aneurysm the overall survival was 75% and 49% at 5 years and 10 years, respectively.17, Because almost half (48%) of the asymptomatic cohort had cardiac disease registered, comparisons with longevity after coronary artery bypass grafting may also be of interest, and in a large study of coronary artery bypass grafting the 10-year survival was 70%.18. This consequently indicates that the remaining patients (13%) who had undergone other peripheral vascular procedures (ie, operations for PAD or aneurysms) had an even higher late mortality. There are some recent natural history studies on long-term survival in patients with asymptomatic carotid artery stenosis, but because of differences in study population and definition of stenosis, comparisons are difficult. Long-term survival after CEA for asymptomatic stenosis may be an important consideration in deciding on this prophylactic procedure, but is not well documented. Cao et al4 analyzed late survival after CEA for asymptomatic lesions and correlated it to the presence of silent brain infarctions, with a 5-year survival of 86.0% without versus 78.3% with silent brain infarctions, and a 10-year survival of 69.3% versus 60.6%, respectively. You may feel more tired than usual for several weeks after surgery. Local Info More recently, carotid stents (think cardiac stents, only bigger) have been used. Results— A total of 6169 CEAs in 5808 patients were registered, with a median time at risk of 5.1 (range, 0.1 to 11.8) years. The mean age (70 years) in this series is somewhat higher than in the ACAS (67 years) and the ACST (68 years), but similar to most series on survival after CEA.
