Risk, prevention, screening and management of carotid artery stenosis in head & neck cancer patients-An evidence based review. Oral Oncol 2024; 156:106876. [PMID: 38908097 DOI: 10.1016/j.oraloncology.2024.106876] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/11/2024] [Revised: 05/12/2024] [Accepted: 05/28/2024] [Indexed: 06/24/2024]
Abstract
Our review aims to clarify the incidence of carotid artery stenosis, risks of development, screening, management, and primary prevention strategies documented in the literature after radiation therapy for head and neck cancers. The high prevalence of carotid stenosis after radiation therapy for head and neck cancers has made surveillance and risk stratification critical. In addition to general cardiovascular risk factors such as smoking, diabetes, and dyslipidemia, risk factors for carotid artery stenosis after head and neck radiation included total plaque score, radiotherapy use and dosage, length of time after radiotherapy, and age greater than 50. Cancer subtype, namely nasopharyngeal cancer, may be correlated with increased risk as well, though contrasting results have been found. Interestingly, however, no significant relationship has been found between radiotherapy dose and stroke risk. Surgical management of post-radiation carotid stenosis is similar to that of stenosis unrelated to radiation, with carotid endarterectomy considered to be the gold standard treatment and carotid artery stenting being an acceptable, less-invasive alternative. Medical management of these patients has not been well-studied, but antiplatelet therapy, statins, and blood pressure control may be beneficial. The mainstay of screening for radiation-induced stenosis has been Doppler ultrasound, with measurement of changes in the intima-media thickness being a primary marker of disease development. A literature review was carried out using the MeSH terms "Carotid Artery Stenosis," "Head and Neck Neoplasms," and "Radiotherapy."

Abstract
PURPOSE Carotid artery stenting (CAS) appears as a promising alternative treatment to carotid endarterectomy for radiation therapy (RT)-induced carotid stenosis. However, this is based on a poor level of evidence studies (small sample size, primarily single institution reports, few long-term data). The purpose of this study was to report the long-term outcomes of a multicentric series of CAS for RT-induced stenosis. METHODS All CAS for RT-induced stenosis performed in 11 French academic institutions from 2005 to 2017 were collected in this retrospective study. Patient demographics, clinical risk factors, elapsed time from RT, clinical presentation and imaging parameters of carotid stenosis were preoperatively gathered. Long-term outcomes were determined by clinical follow-up and duplex ultrasound. The primary endpoint was the occurrence of cerebrovascular events during follow-up. Secondary endpoints included perioperative morbidity and mortality rate, long-term mortality rate, primary patency, and target lesion revascularization. RESULTS One hundred and twenty-one CAS procedures were performed in 112 patients. The mean interval between irradiation and CAS was 15 ± 12 years. In 31.4% of cases, the lesion was symptomatic. Mean follow-up was 42.5 ± 32.6 months (range 1-141 months). The mortality rate at 5 years was 23%. The neurologic event-free survival and the in-stent restenosis rates at 5 years were 87.8% and 38.9%, respectively. Diabetes mellitus (p=0.02) and single postoperative antiplatelet therapy (p=0.001) were found to be significant predictors of in-stent restenosis. Freedom from target lesion revascularization was 91.9% at 5 years. CONCLUSION This study showed that CAS is an effective option for RT-induced stenosis in patients not favorable to carotid endarterectomy. The CAS was associated with a low rate of neurological events and reinterventions at long-term follow-up.

Abstract
OBJECTIVE Head and neck malignancies are often treated with radiotherapy (RT). Nearly 80% of patients who have undergone RT will develop carotid radiation arteritis to some degree and 29% will develop stenosis >50%. Surgery in a radiated neck has higher rates of complications, and carotid artery stenting (CAS) has become the primary therapy. The outcomes for CAS in patients with radiation arteritis have not been rigorously evaluated. The objective of the present study was to evaluate the differences in perioperative outcomes, restenosis rates, the need for reintervention, and freedom from mortality between RT patients and patients with atherosclerotic disease who had undergone CAS. METHODS The national Vascular Quality Initiative CAS dataset from 2016 to 2019 comprised the sample for analyses (n = 7343). The primary independent variable was previous head and/or neck RT. The primary endpoint was the interval to mortality. The secondary endpoints were the cumulative incidence of restenosis (>50% and >70% by duplex ultrasound) and reintervention. We also examined the following secondary perioperative endpoints: myocardial infarction, in-hospital mortality (death before discharge), neurologic events, ipsilateral stroke, and contralateral stroke. Kaplan-Meier and multivariable Cox proportional hazard models were used to assess for mortality, and cumulative incidence function estimates were used for the nonfatal endpoints. RESULTS Of the 7218 patients, 1199 (17%) had undergone prior RT. We found a significant difference in the 3-year estimates of mortality for those with and without prior RT (9.4% and 7.5%, respectively; P = .03). Furthermore, on adjusted analysis, we observed a 58% increase in the risk of mortality for those with prior RT (adjusted hazard ratio, 1.58; 95% confidence interval, 1.13-2.21). We did not observe any differences in the risk of perioperative complications (myocardial infarction, in-hospital mortality, ipsilateral or contralateral stroke), restenosis (>50% or >70%), or reintervention for the prior RT group compared with those without RT. CONCLUSIONS The CAS patients with RT had significantly greater mortality at all time points compared with those without RT, even after adjusting for other covariates. No significant difference was found in the incidence of perioperative complications, reintervention, or restenosis between the two groups. The present study is unique because of the large sample size and length of follow-up. The results suggest that for this high-risk group, CAS provides the same patency as it does for atherosclerotic carotid stenosis and avoids potentially morbid cranial nerve injury and wound healing complications.

Abstract
Neurologic symptoms are commonly seen in patients with cancer and can be among the most challenging to diagnose and manage. It is often difficult to determine if new neurologic symptoms are secondary to direct effects of a malignant lesion, systemic complications of disease, paraneoplastic disorders, or side effects of cancer treatment itself. However, early diagnosis and treatment of each of these conditions can improve patients' quality of life and long-term functional outcomes. In this review, we describe a systematic approach to the diagnosis of new neurologic symptoms in patients with known malignancy. We have categorized the neurologic complications of cancer through a mechanistic approach, with an emphasis on ascertaining underlying pathophysiology to guide treatment choice. This review focuses on the acute neurologic complications of cancer that require hospital admission.

Abstract
Objective This study was performed to evaluate the safety and efficacy of endovascular stenting and embolization for the management of radiation-induced peripheral arterial pseudoaneurysms. Methods Twelve consecutive patients with radiation-induced peripheral arterial pseudoaneurysms (diameter of 10–30 mm and mean size of 20.42 mm) were admitted to our hospital from 1 January 2015 to 31 October 2019. The patients’ baseline characteristics, perioperative parameters, device characteristics, and curative effects were systematically recorded and analyzed. Results The 12 patients comprised 3 men and 9 women with a mean age of 62.90 ± 13.97 years. The iliac artery was the most commonly involved artery, followed by the subclavian artery. In all patients, the pseudoaneurysms were detected by enhanced computed tomography. Twelve covered stents were deployed (7 or 8 mm in diameter and 50 mm in length). Additional coil embolization was performed in three patients (Patients 8, 9, and 10). The primary and secondary technical success rate was 91.7% and 100%, respectively. Apart from one death caused by rebleeding, no patients developed rebleeding during follow-up. Conclusion Endovascular stenting and coil embolization are feasible and effective for the management of radiation-induced peripheral arterial pseudoaneurysms in highly selected patients.

Is radiation-induced arteriopathy in long-term breast cancer survivors an underdiagnosed situation?: Critical and pragmatic review of available literature. Radiother Oncol 2021; 157:163-174. [PMID: 33515666 DOI: 10.1016/j.radonc.2021.01.009] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/11/2020] [Revised: 01/01/2021] [Accepted: 01/10/2021] [Indexed: 12/24/2022]
Abstract
PURPOSE Although considered exceptional, radiation-induced arteriopathy in long-term breast cancer survivors involves three main arterial domains in the irradiated volume, namely axillary-subclavian, coronary, and carotid. Stenosis of medium-large arteries is caused by "accelerated" atherosclerosis, particularly beyond 10 years after long-forgotten radiotherapy. The present review aims at summarizing what is known about arteriopathy, as well as the state of the art in terms of diagnosis and therapeutic management. DIAGNOSIS Pauci-symptomatic over years, the usual clinical presentation of arteriopathy involves arm pain with coldness due to subacute or critical ischemia (arterial occlusion), wrongly attributed to an exclusive neurological disorder, and more rarely transient ischemic accident or angina. Evaluation of the supra-aortic trunks by computed tomography and/or magnetic resonance angiography visualizes artery lesions, while Doppler ultrasonography in expert hands assesses diagnosis and downstream functional impact. In severe cases, more invasive angiography directly visualizes long irregular arterial stenosis (full-field radiotherapy), allowing accurate prognosis and treatment. MANAGEMENT Requires early diagnosis to enable initiation of medical treatment that increases blood flow (aspirin) as soon as moderate stenosis is detected, combined with correction of vascular risk factors. In intermediate cases, these therapeutic measures are completed by revascularization strategies using transluminal angioplasty-stenting (wall thickness). Antifibrotic treatment is useful in advanced cases with combined radiation injuries. CONCLUSION In follow-up of long-term breast cancer survivors with node irradiation, myocardial infarction is treated even if radiotherapy is forgotten, while recognition and diagnosis of chronic arm ischemia due to subclavian artery stenosis needs to be improved for appropriate therapeutic management.

Abstract
BACKGROUND This study aimed to review short- and long-term outcomes of all carotid artery stenting (CAS) in patients with radiation-induced (RI) internal carotid artery (ICA) stenosis compared with patients with atherosclerotic stenosis (AS). METHODS We performed a single-center, multisite case-control study of transfemoral carotid artery intervention in patients stented for RI or AS. Cases of stented RI carotid arteries were identified using a CAS database covering January 2000 to December 2019. These patients were randomly matched 2:1 with stented patients because of AS by age, sex, and year of CAS. A conditional logistic regression model was performed to estimate the odds of reintervention in the RI group. Finally, a systematic review was performed to assess the outcomes of RI stenosis treated with CAS. RESULTS There were 120 CAS in 113 patients because of RI ICA stenosis. Eighty-nine patients (78.8%) were male, and 68 patients (60.2%) were symptomatic. The reasons for radiation included most commonly treatment for diverse malignancies of the head and neck in 109 patients (96.5%). The mean radiation dose was 58.9 ± 15.6 Gy, and the time from radiation to CAS was 175.3 ± 140.4 months. Symptoms included 31 transient ischemic attacks (TIAs), 21 strokes (7 acute and 14 subacute), and 17 amaurosis fugax. The mean National Institutes of Health Stroke Scale in acute strokes was 8.7 ± 11.2. In asymptomatic patients, the indication for CAS was high-grade stenosis determined by duplex ultrasound. All CAS were successfully completed. Reinterventions were more frequent in the RI ICA stenosis cohort compared with the AS cohort (10.1% vs. 1.4%). Reinterventions occurred in 14 vessels, and causes for reintervention were restenosis in 12 followed by TIA/stroke in two vessels. On conditional regression modeling, patients with RI ICA stenosis were at a higher risk for reintervention (odds ratio = 7.1, 95% confidence interval = 2.1-32.8; P = 0.004). The mean follow-up was 33.7 ± 36.9 months, and the mortality across groups was no different (P = 0.12). CONCLUSIONS In our single-center, multisite cohort study, patients who underwent CAS for RI ICA stenosis experienced a higher rate of restenosis and a higher number of reinterventions compared with CAS for AS. Although CAS is safe and effective for this RI ICA stenosis cohort, further data are needed to reduce the risk of restenosis, and close patient surveillance is warranted. In our systematic review, CAS was considered an excellent alternative option for the treatment of patients with RI ICA stenosis. However, careful patient selection is warranted because of the increased risk of restenosis on long-term follow-up.

Abstract
BACKGROUND Patients meeting criteria for intervention of carotid stenosis with a history of prior cervical radiation or neck dissection are considered "high risk" for carotid endarterectomy. This is a well-established indication for carotid artery stenting (CAS). The long-term outcomes of CAS in this population are less frequently published in the literature but are poor. The purpose of this study was to review long-term results of CAS in veteran patients with a prior history of treatment for head and/or neck cancer. METHODS This is a retrospective review of a veteran patient population from 1998 to 2016. All patients at our institution with a prior history of treatment for head and/or neck cancer who underwent CAS were included in the analysis. During this time period, 44 patients met inclusion criteria and were treated with 57 carotid stenting interventions. The Kaplan-Meier analysis was used to determine survival and primary patency. The secondary aims were to analyze early outcomes and to identify predictive risk factors for mortality and reintervention. RESULTS The mean follow-up was 42.9 ± 36.6 months. The cumulative survival at 1, 5, and 10 years was 91%, 67%, and 48%, respectively. The primary patency at 1, 5, and 10 years was 95%, 86%, and 86%, respectively. The reintervention rate was 11% (n = 6) with an assisted primary patency rate of 100%. No neurologic events occurred within 30 days. There were 3 strokes in late follow-up and no stroke-related deaths. Eighteen patients (41%) died during the follow-up period, 15 of whom died during the first 5 years of follow-up. Ten (66%) of those patients died of recurrent or active index cancer. On univariate analysis, tumor, node, metastasis stage IV was significantly associated with death (P = 0.02). Multivariate models were not statistically significant for predicting mortality or reintervention CONCLUSIONS: On the basis of the results in this series, CAS can be performed in these patients with low long-term rates of neurologic events and need for reintervention. However, the survival of patients with head and neck cancer undergoing CAS in this cohort is poor, which is consistent with other published series of patients undergoing CAS for head/neck cancer with at least 5-year follow-up. In this specific patient population, a more critical analysis of the patient's overall prognosis, especially as related to cancer, should be undertaken before offering CAS.

Abstract
BACKGROUND The prevalence of survivors of oropharyngeal cancer (OPC) is increasing due to improved survival for individuals with human papillomavirus (HPV)-related disease. Although elderly survivors of OPC are known to have a high burden of comorbidities, to the authors' knowledge it is unknown how this compares with a similar cohort without a history of cancer. METHODS The current retrospective, cross-sectional study included individuals with a first incident primary diagnosis of OPC from 2004 through 2011 from the Surveillance, Epidemiology, and End Results (SEER)-Medicare-linked databases and matched controls. The baseline prevalence and subsequent incidence of comorbid conditions were identified. The association between comorbidity and overall survival was evaluated. RESULTS A total of 2497 eligible patients with OPC were matched to 4994 noncancer controls. Baseline comorbidity was higher in cases (Charlson Comorbidity Index >0 for 48.5% of cases vs 35.8% of controls). At 5 years, cases were more likely than controls to develop comorbidities. Survivors of OPC were at high risk (≥20% cumulative prevalence by 5 years) of developing several comorbidities, including cardiovascular diseases, cerebrovascular disease, chronic obstructive pulmonary disease, and tobacco abuse, and were at moderately high risk (10%-19% cumulative prevalence) of developing other conditions including carotid artery occlusive stroke, alcohol abuse, depression, and anxiety. In both cases and controls, the presence of the majority of comorbidities either at the time of diagnosis or during the follow-up period was associated with worse survival. CONCLUSIONS Patients with OPC have a higher comorbidity burden compared with matched controls, both at baseline and during survivorship, the majority of which are associated with decreased survival. Oncologic surveillance of survivors of OPC should include screening for highly prevalent conditions.

Predictors of midterm high-grade restenosis after carotid revascularization in a multicenter national database. J Vasc Surg 2020; 71:1972-1981. [PMID: 32085958 DOI: 10.1016/j.jvs.2019.07.100] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2019] [Accepted: 07/25/2019] [Indexed: 11/20/2022]
Abstract
BACKGROUND Restenosis after carotid revascularization is clinically challenging. Several studies have looked into the management of recurrent restenosis; however, studies looking into factors associated with restenosis are limited. This study evaluated the predictors of restenosis after carotid artery stenting (CAS) and carotid endarterectomy (CEA) using a large national database. METHODS Patients undergoing CEA or CAS in the Vascular Quality Initiative data set (2003-2016) were analyzed. Patients with no follow-up (33%) and those who had prior ipsilateral CEA or CAS were excluded. Significant restenosis was defined as ≥70% diameter-reducing stenosis, target artery occlusion or peak systolic velocity ≥300 cm/s, or repeated revascularization. Kaplan-Meier survival analysis and bootstrapped Cox regression models with stepwise forward and backward selection were used. RESULTS A total of 35,720 procedures were included (CEA, 31,329; CAS, 4391). No significant difference in restenosis rates was seen between CEA and CAS at 2 years (7.7% vs 9.4% [P = .09]; hazard ratio [HR], 0.99; 95% confidence interval [CI], 0.79-1.25; P = .97). However, after adjustment for age, sex, and symptomatic status at the time of the index operation, CAS patients who had postoperative restenosis were more likely to have a symptomatic presentation (odds ratio, 2.2; 95% CI, 1.2-4.0; P = .01) and to undergo repeated revascularization at 2 years (HR, 1.75; 95% CI, 1.3-2.4; P < .001) compared with patients who had restenosis after CEA. Predictors of restenosis after CAS included a common carotid artery lesion (HR, 1.65; 95% CI,1.06-2.57; P = .03), whereas age (HR, 0.91; 95% CI, 0.84-0.99; P = .03) and dilation after stent placement (HR, 0.53; 95% CI, 0.39-0.72; P < .001) were associated with decreased restenosis at 2 years. Predictors of restenosis after CEA included female sex (HR, 1.55; 95% CI, 1.38-1.74; P < .001), prior neck irradiation (HR, 2.35; 95% CI, 1.66-3.30; P < .001), and prior bypass surgery (HR, 1.29; 95% CI, 1.01-1.65; P = .04). On the other hand, factors associated with decreased restenosis after CEA included age (HR, 0.95; 95% CI, 0.92-0.98; P < .001), black race (HR, 0.57; 95% CI, 0.37-0.89; P = .01), patching (HR, 0.61; 95% CI, 0.47-0.79; P < .001), and completion imaging (HR, 0.70; 95% CI, 0.52-0.95; P = .02). CONCLUSIONS Our results show no significant difference in restenosis rates at 2 years between CEA and CAS. Restenosis after CAS is more likely to be manifested with symptoms and to undergo repeated revascularization compared with that after CEA. Poststent ballooning after CAS and completion imaging and patching after CEA are associated with decreased hazard of restenosis; however, further research is needed to assess longer term outcomes and to balance the risks vs benefits of certain practices, such as poststent ballooning.

Abstract
OBJECTIVE Carotid endarterectomy and carotid artery stenting are both valid therapeutic options for the treatment of radiation-induced carotid stenosis (RICS). The second has the advantage of being less invasive, although it seems to result in more restenosis than the first. Meanwhile, progress in radiation therapy and head and neck surgery has significantly increased the survival of these patients. As a result, treatment of RICS should be considered from a long-term perspective. This works presents perioperative and follow-up outcomes of surgical treatment of RICS. METHODS This single-center retrospective study included all patients who underwent carotid endarterectomy for RICS from January 1998 to June 2017. Clinical and duplex ultrasound examination-based follow-up was performed postoperatively, at 1 month, 6 months, 12 months, and yearly thereafter. Kaplan-Meier curves were used for survival plots based on a log-rank test. Any abnormal finding led to angio-computed tomography scan and specialized neurovascular examination. RESULTS Between 1998 and 2017, 128 patients (162 lesions) were treated. The median interval between radiation therapy and surgery was 16 years. Forty-five patients (35%) were symptomatic. The eversion technique was performed in 79 cases (49%), and the patch was favored in 24 cases (15%), prosthetic bypass graft in 51 cases (31%), and a venous bypass graft in 8 cases (5%). Two postoperative deaths (1.5%) (one secondary to massive stroke) were noted. The primary end point of early postoperative cerebrovascular event was 2.5%. Two cervical hematomas (1.2%) required surgical revision and seven cases of permanent cranial nerve injury were recorded. The median follow-up was 29 months (range, 2-199 months). There were no additional strokes. The 3-year primary patency rate was 96% and the 3-year freedom from neurologic event was 98%. CONCLUSIONS Open surgical treatment of RICS lesions is a safe and durable option. Our results suggest that the outcomes of such treatment are good and in particular that rates of cerebrovascular event and restenosis are low and that cranial nerve injury should not be a concern. As a result, we consider that open surgery for RICS lesions should be offered as a first-line treatment. However, comparative data are mandated to address this issue.

Abstract
The term "radiation vasculopathy" defines a heterogeneous and poorly defined complex of vessel injury due to radiation. Radiation vasculopathy remains underrecognized and poorly treated with respect to head and neck radiotherapy. Distinct injury patterns to small (≤ 100-μm), medium (> 100-μm), and large (> 500-μm) vessels can occur, resulting in carotid stenosis, intracranial stenosis, and vascular anomalies (e.g., cavernous malformations, aneurysms). Because of the lack of clinical evidence and guidelines, treatment plans involve medical management, carotid endarterectomy, and carotid artery stenting and are developed on a patient-by-patient basis. In this review, the authors discuss the current pathophysiology, imaging, clinical impact, and potential treatment strategies of radiation vasculopathy with clinical pertinence to practicing neurosurgeons and neurologists. A review of 4 patients with prior head and neck tumors in whom delayed radiation vasculopathy developed after radiotherapy demonstrates the application of various treatment options in a case-by-case manner. Earlier recognition of radiation vasculopathy disease patterns may enable earlier initiation of treatment and monitoring for complications. Standardized terminology and treatments may assist with improving clinical outcomes.

Abstract
Carotid artery stenting (CAS) is increasingly utilized in patients with carotid artery stenosis. Various intraprocedural and postprocedural complications have been reported in the literature. We present a case of symptomatic major thromboembolism after CAS. The intraprocedural angiogram showed extraordinary slow filling of the contrast medium into the plaque, which we named as "crevice sign." An 83-year-old man presented repeat right amaurosis fugax for 6 months. The radiological examinations revealed 85% stenosis of the origin of the right internal carotid artery. The patient underwent right CAS. The procedure was performed without any problems; however, the angiogram showed slow filling of contrast medium into the carotid plaque through the stent (crevice sign). Sixty minutes later in the ward, the patient presented sudden onset of left hemiparesis and aphasia. Emergency catheter angiography did not show in-stent thrombus, major artery occlusion, or the crevice sign. Magnetic resonance imaging on the next day revealed wide acute infarction of the right cerebral hemisphere. Physicians should be aware of the intraprocedural crevice sign so that a subsequent catastrophic ischemic event can be prevented.

Abstract
INTRODUCTION Surgical treatment of radio-induced carotid stenosis (RICS) is challenging and burdened by an elevated risk of local complications. Carotid artery stenting (CAS) may be a suitable alternative. The best approach is yet to be defined. We reviewed the results of both techniques following selection based on better-suitability characteristics (anatomic and clinical). METHODS We retrospectively reviewed 38 patients treated for 43 RICS from a group of 1230 patients who had carotid interventions between 2008 and 2015 (5 bilateral). Primary endpoints were morbidity and mortality at 30 days (transient ischemic attack, stroke, myocardial infarction, or death). Secondary endpoints were technical success, wound complications, cranial nerve injury (CNI), restenosis (≥50%) and recurrent symptoms. RESULTS RICS was symptomatic in 6 patients in the OR group and 3 in the CAS group. Lesions in the OR group were longer (P=0.02) and more calcified (P=0.08). Technical success rate was 100%. Cranial nerve injury rate was 14.2% (3/21). All injuries were completely resolved within several weeks. In the CAS group, technical success rate was 95% (21/22) with the one failure due to a residual stenosis exceeding 30%. Periprocedural stroke rates were 0% and 4.5% in the OR and CAS groups respectively (0/21 vs 1/22, P=0.32). There were no early deaths. Mean follow-up was 19.1 months (3-75). The restenosis rate was 9.5% (2/21) in the OR group and 9% (2/22) in the CAS group. CONCLUSION Our results do not support a preferred treatment strategy. The choice of treatment should be considered on an individual basis.

Abstract
OBJECTIVE Neck radiation therapy (XRT) can induce carotid artery stenosis and may increase the technical difficulty of endarterectomy. It is considered a relative indication for carotid angioplasty and carotid artery stenting (CAS). This study sought to evaluate differences in CAS embolic potential and restenosis performed on XRT and non-XRT patients. METHODS At three institutions, 366 CAS procedures were performed on 321 patients (XRT, n = 43; non-XRT, n = 323). Mean follow-up was 410 days (median, 282 days; range, 7-1920 days). Patients were observed with duplex ultrasound to assess for restenosis. Additional end points included target lesion revascularization (TLR), myocardial and cerebrovascular events, and perioperative complications. Captured particulate from embolic protection filters was analyzed with photomicroscopy and image analysis software for 27 XRT and 214 non-XRT filters. RESULTS XRT patients were more likely to be male and had lower rates of hypertension, coronary artery disease, and diabetes mellitus, although the mean age at procedure did not differ. There was no increase in severe internal carotid tortuosity among XRT patients (XRT: 50% vs non-XRT: 34.7%; P = .06). Indication for CAS did not differ between the two groups, including the number of CAS procedures performed for symptomatic carotid stenosis (XRT: 39.7% vs non-XRT: 39.0%; P = NS). Perioperative outcomes, including the composite 30-day stroke, myocardial infarction, and mortality, were not significantly different (XRT: 2.6% vs non-XRT: 3.9%; P = NS.) There were no significant differences in restenosis rate at the 50% (XRT: 9.4% vs non-XRT: 8.6%; P = NS) or 70% (XRT: 3.5% vs non-XRT: 8.6%; P = NS) threshold. Filter particle analysis revealed that filters from XRT patients had more numerous large particles per filter (1.4 vs 0.7; P < .05) and larger mean particle size (464.1 μm vs 320.0 μm; P < .05). TLR did not differ significantly between the groups. CONCLUSIONS In contrast to earlier studies, this analysis reveals that there are significant differences in XRT and non-XRT patients undergoing CAS in terms of medical comorbidities and embolic material captured in embolic protection filters. The decreased incidence of atherosclerotic risk factors was observed in XRT patients probably because XRT was the primary factor responsible for carotid stenosis. Despite increased embolic particle size, CAS can be performed safely with no increased morbidity, TLR, or restenosis in XRT patients.

Abstract
According to the 2011 and the 2014 updated American Heart Association/American Stroke Association Guidelines, carotid artery stenting (CAS) is indicated as an alternative to carotid endarterectomy (CEA) for the management of symptomatic carotid patients. According to these recommendations, CAS is preferred to CEA in symptomatic patients with specific technical, anatomic, or physiological characteristics that render these individuals at "high risk" for surgery (e.g., contralateral carotid occlusion, previous neck irradiation, recurrent carotid stenosis, and so forth). This article presents emerging data suggesting that most of these criteria do not comprise contraindications for CEA. In fact, CEA is associated with similar (or even better) outcomes compared with CAS in many such "high-risk" patients. Based on these results, the indications of CAS in symptomatic patients may need to be reconsidered.

Abstract
BACKGROUND This study compared the risk of fatal cerebrovascular accidents (CVAs) in patients with early-stage glottic laryngeal cancer receiving surgery or external beam radiation therapy (EBRT). METHODS Using a competing risks survival analysis, we compared the risk of death because of CVA among patients with early-stage glottic laryngeal cancer receiving surgery or EBRT in the Surveillance, Epidemiology, and End Results (SEER) database. RESULTS The cumulative incidence of fatal CVA at 15 years was higher in patients receiving EBRT (2.8%; 95% confidence interval [CI], 2.3% to 3.4%) compared to surgery (1.5%; 95% CI, 0.8% to 2.3%; p = .024). In multivariable competing risks regression models, EBRT remained associated with an increased risk of fatal CVA compared to surgery (adjusted hazard ratio [HR], 1.75; 95% CI, 1.04-2.96; p = .037). CONCLUSION Treatment for early-stage glottic laryngeal cancer with EBRT was associated with a small increase in the risk of late fatal CVA events relative to surgery.

Abstract
The perioperative evaluation of patients with cancer differs from that of other patients in that the former may have received prior chemotherapy or radiation therapy. These cancer treatments have a wide range of side effects and complications that may affect patients' perioperative risks. The perioperative specialist who evaluates the cancer patient prior to surgery must be familiar with the effects of these treatments and their consequences for the major organ systems. The perioperative specialist must also be familiar with the natural history of cancer and have a basic understanding of how cancer affects the body. In this article, we review the perioperative concerns that are specific to the patient with cancer.

Abstract
Thromboangiitis obliterans, or Buerger disease, is a chronic nonatherosclerotic endarteritis manifesting as inflammation and thrombosis of distal extremity small and medium-sized arteries resulting in relapsing episodes of distal extremity ischemia. Takayasu arteritis is a rare syndrome characterized by inflammation of the aortic arch, pulmonary, coronary, and cerebral vessels, presenting with cerebrovascular symptoms, myocardial ischemia, or upper extremity claudication in young, often female, patients. Kawasaki disease is a small- and medium-vessel acute systemic vasculitis of young children, with morbidity and mortality stemming from coronary artery aneurysms. Microscopic polyangiitis, Churg-Strauss syndrome, and Wegener granulomatosis are systemic small-vessel vasculitides, affecting arterioles, capillary beds and venules, and each presenting with variable effects on the pulmonary, renal and gastrointestinal systems.

Abstract
Radiation exposure to the thorax is associated with substantial risk for the subsequent development of cardiovascular disease. Thus, the increasing role of radiation therapy in the contemporary treatment of cancer, combined with improving survival rates of patients undergoing this therapy, contributes to a growing population at risk of cardiovascular morbidity and mortality. Associated cardiovascular injuries include pericardial disease, coronary artery disease, valvular disease, conduction disease, cardiomyopathy, and medium and large vessel vasculopathy-any of which can occur at varying intervals following irradiation. Higher radiation doses, younger age at the time of irradiation, longer intervals from the time of radiation, and coexisting cardiovascular risk factors all predispose to these injuries. The true incidence of radiation-related cardiovascular disease remains uncertain due to lack of large multicentre studies with a sufficient duration of cardiovascular follow-up. There are currently no consensus guidelines available to inform the optimal approach to cardiovascular surveillance of recipients of thoracic radiation. Therefore, we review the cardiovascular consequences of radiation therapy and focus on the potential role of non-invasive cardiovascular imaging in the assessment and management of radiation-related cardiovascular disease. In doing so, we highlight characteristics that can be used to identify individuals at risk for developing post-radiation cardiovascular disease and propose an imaging-based algorithm for their clinical surveillance.

Abstract
BACKGROUND Treatment of head and neck malignancy commonly involves radiotherapy, which is associated with the development of carotid artery stenosis. There is little evidence to guide clinicians on how to intervene in significant postradiotherapy carotid stenosis. This systematic review collated data pertaining to perioperative outcomes of carotid artery surgery and carotid stenting in postradiotherapy carotid stenosis to aid the clinical decision-making process. METHODS A systematic review of the literature, adhering to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2009 guidelines, was performed. We screened 575 articles related to carotid artery surgery or stenting in postradiotherapy carotid stenosis, from which 21 studies were included for quantitative analysis. The primary outcome was stroke or death ≤ 30 days of the procedure. Secondary outcomes included cranial nerve injury, restenosis, stroke, and death at >30 days. RESULTS Nine publications recorded 211 surgical procedures in 179 patients. In symptomatic patients, the 30-day mortality rate was 2.6% and the stroke or death rate was 2.7%. In asymptomatic patients, the 30-day mortality rate was 0% and the stroke or death rate was 1.1%. Permanent cranial nerve palsy was experienced by 0.6% of patients. Twelve publications recorded 510 carotid artery stenting procedures in 482 patients. In symptomatic patients, the 30-day mortality rate was 5.1%, and the stroke or death rate was 5.1%. In asymptomatic patients, the 30-day mortality rate was 1.4%, and the stroke or death rate was 2.1%. There was no statistically significant difference in 30-day stroke or death rate between surgical revascularization and carotid artery stenting in all (odds ratio [OR], 0.54; 95% confidence interval [CI] 0.17-1.70; P = .43), symptomatic (OR, 0.52; 95% CI, 0.14-1.98; P = .38), or asymptomatic patients (OR, 0.55; 95% CI, 0.06-5.42; P = .99). CONCLUSIONS The published outcomes from high-volume centers demonstrate that surgical revascularization and stenting are both technically feasible in postradiotherapy carotid stenosis and have similar safety profiles to nonirradiated necks. Radiation should therefore not be considered a contraindication to surgical intervention.

Abstract
The role of carotid artery stenting (CAS) as an alternative to carotid endarterectomy for the treatment of extracranial carotid occlusive disease for stroke prevention continues to evolve. Although technical and device refinements aimed at making CAS safer continue to this day, safety as measured by 30-day and 1-year outcomes has been the primary recipient of regulatory and practice attention. Relatively less emphasis has been placed on the incidence of recurrent stenosis after CAS and the efficacy of CAS in late stroke prevention. Data on late outcomes of CAS, including factors of potential influence, have been emerging and are addressed in this review.

Abstract
BACKGROUND Chemo-radiotherapy-induced carotid stenosis and cerebrovascular events in head and neck cancer patients can cause severe disability and death. We aimed to estimate the risk of stroke in such patients over a six-year follow-up period. PATIENTS AND METHODS The study cohort consisted of head and neck cancer patients (n=10,172). Cox proportional hazard model was used to compare the stroke-free survival rate between the patients treated with radiotherapy or chemotherapy, surgery alone, and surgery with adjuvant therapy after adjusting for possible confounding factors. RESULTS At the end of follow-up, 384 patients had strokes: 126 (4.3%) from the surgery alone group, 167 (3.8%) from the radiotherapy or chemotherapy group, and 91 (3.2%) from the surgery with adjuvant therapy (P=0.222). Head and neck cancer patients aged less than 55 years treated with radiotherapy or chemotherapy conferred a 1.8-fold higher risk for stroke (95% CI, 1.22-2.56; P=0.003) after adjusting for patient characteristics, co-morbidities, geographic region, urbanization level, and socio-economic status. There was no statistical difference in stroke risk between different treatment modalities in head and neck cancer patients aged 55 years and more. CONCLUSIONS Young head and neck cancer patients treated with radiotherapy or chemotherapy have higher risks for stroke. Different treatment strategies should be considered in such patients.

Abstract
OBJECTIVES A duplex ultrasound study was performed to investigate morphological and hemodynamic patterns of carotid stenoses treated by endarterectomy with patch closure versus stenting. MATERIALS AND METHOD Twenty-nine carotid stenoses were treated with stenting and 65 with patch closure. Duplex ultrasound parameters (luminal diameter, mm; peak systolic velocity and end-diastolic velocity, cm/s) were measured 24 hours after the procedures and also at 12 months post-procedure. Residual stenoses (immediately postprocedure) and restenoses (within 12 months of procedure) were defined as narrowings of ≥ 50% on duplex ultrasound examination. RESULTS In stented patients, the luminal diameter of the proximal internal carotid artery increased in the interval between the 24-hour and 12-month post-procedure studies, while in the patch closure patients, the diameter decreased. Carotid hemodynamics normalized immediately after both patching and stenting and remained relatively stable thereafter up to 12 months. No statistically elevated flow velocities (in the absence of residual stenosis or restenosis) were observed in the patched or stented carotid arteries. No significant differences in residual stenosis rates were observed between the stenting group (3 cases, 10.34%) and the patch closure group (1 case, 1.53%, P = 0.08). At 12 months, 2 stenting patients (6.88%) and 2 patch closure patients (3.07%) had $50% restenosis (P = 0.58). One case of late stroke due to restenosis was observed in the stenting group; the patient died 12 months postoperatively, before receiving new intervention. CONCLUSION Measurements over time in luminal diameter signalized differences in arterial remodeling mechanisms between patched and stented carotids. Both stenting and patch closure were associated with carotid patency and flow restoration. This study does not support a general approach to new velocity criteria indiscriminately applied to stented or patched carotids.
