Role of pre-operative frailty status in relation to outcome after carotid endarterectomy: a systematic review.

ABSTRACT: Carotid endarterectomy (CEA) is a surgical treatment option to prevent ischemic cerebrovascular accidents. Patients that present with pre-operative frailty might have an elevated risk for unfavorable outcomes after the CEA. A systematic search, using Medline, Embase, Web of Science and Cochrane Database, was performed for relevant literature on frailty in patients undergoing CEA. The study protocol was registered with PROSPERO (CRD42020190345). Eight articles were included. The pooled prevalence for pre-operative frailty was 23.9% (95% CI: 12.98-34.82). A difference in the incidence of complications between frail and non-frail patients (6.4% vs. 5.2%, respectively) and a difference in hospital length of stay [2 (IQR: 2-3) days vs. 1 (IQR: 1-2) day, respectively] were described. The 30-day mortality after CEA was 0.6% for non-frail patients, 2.6% for frail patients, and 4.9% for very frail patients (P<0.001). For 3-year mortality, a >1.5-fold increased risk was found for frail patients (OR 1.7, 95% CI: 1.4-2.0) and a >2.5-fold increased risk for very frail patients (OR 2.6, 95% CI: 2.2-3.1). In conclusion, this review shows the impact of frailty on outcome after CEA. Pre-operative frailty assessment with a validated, multi-domain tool should be implemented in the clinical setting as it will provide information on post-operative surgical outcomes and mortality risk but also frailty trajectory and cognitive decline.

Project description:ObjectiveUnderinsured patients can experience worse preoperative medical optimization. We aimed to determine whether insurance status was associated with carotid endarterectomy (CEA) urgency and postoperative outcomes.MethodsWe analyzed the Society for Vascular Surgery Vascular Quality Initiative Carotid Endarterectomy dataset from January 2012 to January 2021. Univariable and multivariable methods were used to analyze the differences across the insurance types for the primary outcome variable: CEA urgency. The analyses were limited to patients aged <65 years to minimize age confounding across insurers. We also examined differences in preoperative medical optimization and symptomatic disease and postoperative outcomes. A secondary analysis was performed to examine the effect of CEA urgency on the postoperative outcomes.ResultsA total of 27,331 patients had undergone first-time CEA. Of these patients, 4600 (17%) had Medicare, 3440 (13%) had Medicaid, 17,917 (65%) had commercial insurance, and 1374 (5%) were uninsured. The Medicaid and uninsured patients had higher rates of urgent operation compared with Medicare (20.0% and 34.7% vs 14.4%; P < .001), with no differences in the commercial group vs the Medicare group. Additionally, Medicaid and uninsured patients had lower rates of aspirin, statin, and/or antiplatelet use (93.6% and 93.5% vs 95.8%; P < .001) and higher rates of symptomatic disease (42.1% and 57.6% vs 36.2%; P < .001) compared with Medicare patients. The rate of perioperative stroke/death was higher for the Medicaid and uninsured patients than for the Medicare patients (1.63% and 1.89% vs 1.02%; P = .017 and P = .01, respectively), with no differences in the commercial group. Multivariable analysis demonstrated that compared with Medicare, Medicaid and uninsured status were associated with increased odds of an urgent operation (odds ratio [OR], 1.3; 95% confidence interval [CI], 1.1-1.5; and OR, 2.3; 95% CI, 2.0-2.7, respectively), symptomatic disease (OR, 1.2; 95% CI, 1.1-1.4; and OR, 2.2; 95% CI, 1.9-2.5, respectively), and perioperative stroke/death (OR, 1.6; 95% CI, 1.1-2.4; and OR, 1.8; 95% CI, 1.1-3.0, respectively) and a decreased odds of aspirin, statin, and/or antiplatelet use (OR, 0.71; 95% CI, 0.6-0.9; and OR, 0.76; 95% CI, 0.6-0.99, respectively). Additionally, the rates of perioperative stroke/death were higher for patients who had required urgent surgery compared with elective surgery (2.8% vs 1.0%; P < .001). Multivariable analysis demonstrated increased odds of perioperative stroke/death for patients who had required urgent surgery (OR, 2.4; 95% CI, 1.9-3.1).ConclusionsMedicaid and uninsured patients were more likely to require urgent CEA, in part because of poor preoperative medical optimization. Additionally, urgent operation was independently associated with worse postoperative outcomes. These results highlight the need for improved preoperative follow-up for underinsured populations.

Project description:Carotid endarterectomy (CEA) with patch angioplasty is a widely used method for treating carotid artery stenosis. Patch infections are extremely rare, but the consequences may be serious. The current gold standard for treatment is patch excision and reconstruction with autologous material. However, no consensus has been reached and other options may be valuable as well in certain cases. The objective of this study was to evaluate the various treatment options for carotid patch infection after CEA with patch angioplasty on the basis of their outcomes (reinfection, ischemic stroke, and infection-related mortality). This systematic review was conducted in accordance with the PRISMA statement. The electronic bibliographic databases PubMed, Cochrane, and EMBASE were searched. Case series and case reports were included. Studies in languages other than English were excluded. Patients who developed a post-operative patch infection of CEA with patch angioplasty were included. Angioplasty could be performed with any type of patch. Patch infection needed to be confirmed by clinical presentation in combination with imaging, culture, or during the operation. The primary outcome measures were reinfection, ischemic stroke, and infection-related mortality. Eleven retrospective case series, two prospective case series, and seventeen case reports were included. The study size was 165 patients (mean age 69.7 years, M/F ratio 1.75:1). One hundred and seventy-one patches developed a patch infection after CEA with patch angioplasty and needed treatment. Treatment strategies included conservative treatment (14.0%), endovascular treatment (4.7%), and open surgery (81.4%). Mean follow-up was 34.8 months and extended up to 180 months. Reinfection rate was 4.7%, ischemic stroke rate 5.8%, and infection-related mortality rate 2.3%. No statistical comparison between treatment options could be performed, because of the heterogeneity of the included studies. Autologous material should be the primary choice of treatment if patch infection is diagnosed after CEA with patch angioplasty. In emergency situations, endovascular treatment, carotid ligation, or abscess drainage could be considered. Endovascular treatment and abscess drainage are temporary solutions. After the patient has recovered sufficiently, a more durable treatment i.e., open surgery is advised. Endo vacuum assisted closure (EndoVAC) seems to be promising. Further research is needed to determine the applicability of each treatment option.
