Comparison of clinical profiles and care for patients with incident versus recurrent acute coronary syndromes in France: Data from the MONICA registries.

BACKGROUND: Recurrence is common after an acute coronary syndrome (ACS). In order to better assess the prognosis for patients with ACS, we compared clinical profiles, treatments, and case fatality rates for incident vs. recurrent ACS. METHODS: We enrolled 1,459 men and women (age: 35-74) living in three geographical areas covered by French MONICA registries and who had been admitted to hospital for an ACS in 2015/2016. We recorded and compared the clinical characteristics and medical care for patients with an incident vs. a recurrent ACS. RESULTS: Overall, 431 (30%) had a recurrent ACS. Relative to patients with an incident ACS, patients with recurrence were older (p<0.0001), had a greater frequency of NSTEMI or UA (p<0.0001), were less likely to show typical symptoms (p = 0.045), were more likely to have an altered LVEF (p<0.0001) and co-morbidities. Angioplasty was less frequently performed among patients with recurrent than incident NSTEMI (p<0.05). There were no intergroup differences in the prescription of the recommended secondary prevention measures upon hospital discharge, except for functional rehabilitation more frequently prescribed among incident patients (p<0.0001). Although the crude 1-year mortality rate was higher for recurrent cases (14%) than for incident cases (8%) (p<0.05), this difference was no longer significant after adjustment for age, sex, region, diagnosis category and LVEF. CONCLUSION: Compared with incident patients, recurrent cases were more likely to have co-morbidities and to have suboptimal treatments prior to hospital stay, reinforcing the need for secondary prevention.

Procedural and 12-month in-hospital costs of primary infra-popliteal bypass surgery, infrapopliteal best endovascular treatment, and major lower limb amputation for chronic limb threatening ischemia.

OBJECTIVE: Chronic limb-threatening ischemia (CLTI) is a growing global problem due to the widespread use of tobacco and increasing prevalence of diabetes. Although the financial consequences are considerable, few studies have compared the relative cost-effectiveness of different CLTI management strategies. The Bypass vs Angioplasty in Severe Ischaemia of the Leg (BASIL)-2 trial is randomizing patients with CLTI to primary infrapopliteal (IP) vein bypass surgery (BS) or best endovascular treatment (BET) and includes a comprehensive within-trial cost-utility analysis. The aim of this study is to compare over a 12-month time horizon, the costs of primary IP BS, IP best endovascular treatment (BET), and major limb major amputation (MLLA) to inform the BASIL-2 cost-utility analysis. METHODS: We compared procedural human resource (HR) costs and total in-hospital costs for the index admission, and over the following 12-months, in 60 consecutive patients undergoing primary IP BS (n = 20), IP BET (n = 20), or MLLA (10 transfemoral and 10 transtibial) for CLTI within the BASIL prospective cohort study. RESULTS: Procedural HR costs were greatest for BS (BS £2551; 95% confidence interval [CI], £1934-£2807 vs MLLA £1130; 95% CI, £1046-£1297 vs BET £329; 95% CI, £242-£390; P < .001, Kruskal-Wallis) due to longer procedure duration and greater staff requirement. With regard to the index admission, MLLA was the most expensive due to longer hospital stay (MLLA £13,320; 95% CI, £8986-£18,616 vs BS £8714; 95% CI, £6097-£11,973 vs BET £4813; 95% CI, £3529-£6097; P < .001, Kruskal-Wallis). The total cost of the index admission and in-hospital care over the following 12 months remained least for BET (MLLA £26,327; 95% CI, £17,653-£30,458 vs BS £20,401; 95% CI, £12,071-£23,926 vs BET £12,298; 95% CI, £6961-£15,439; P < .001, Kruskal-Wallis). CONCLUSIONS: Over a 12-month time horizon, MLLA and IP BS are more expensive than IP BET in terms of procedural HR costs and total in-hospital costs. These economic data, together with quality of life data from BASIL-2, will inform the calculation of incremental cost-effectiveness ratios for different CLTI management strategies within the BASIL-2 cost-utility analysis.

Pedal arterial calcification score is associated with the risk of major amputation in chronic limb-threatening ischemia.

OBJECTIVE: The medial arterial calcification (MAC) score is a simple metric that describes the burden of inframalleolar calcification using a plain foot radiograph. We hypothesized that a higher MAC score would be independently associated with the risk of major amputation in patients with chronic limb-threatening ischemia (CLTI). METHODS: We performed a single-institution, retrospective study of 250 patients who had undergone infrainguinal revascularization for CLTI from January 2011 to July 2019 and had foot radiographs available for MAC score calculation. A single blinded reviewer assigned MAC scores of 0 to 5 using two-view minimum plain foot radiographs, with 1 point each for calcification of >2 cm in the dorsalis pedis, plantar, and metatarsal arteries and >1 cm in the hallux and non-hallux digital arteries. RESULTS: The MAC score was 0 in 36%, 1 in 5.2%, 2 in 8.4%, 3 in 14%, 4 in 14%, and 5 in 21%. The MAC score was trichotomized to facilitate analysis and clinical utility (mild, MAC score 0-1; moderate, MAC score 2-4; and severe, MAC score 5). The variables independently associated with a higher MAC score were male sex, diabetes, end-stage renal disease, and the global limb anatomic staging system pedal score. The MAC score was not associated with the Society for Vascular Surgery WIfI (wound, ischemia, foot infection) grade or overall WIfI stage (P = .58). The median follow-up was 759 days (interquartile range, 264-1541 days). A higher MAC score was significantly associated with the risk of major amputation (P < .0001). In a Cox proportional hazards multiple regression model for major amputation that included the trichotomized MAC score, diabetes, end-stage renal disease, and WIfI stage (1-3 vs 4). The MAC score (MAC score 5: hazard ratio [HR], 4.9; 95% confidence interval [CI], 1.9-13.1; P = .001; MAC score 2-4: HR, 3.4; 95% CI, 1.3-8.8; P = .01) and WIfI stage (WIfI stage 4: HR, 2.1; 95% CI, 1.1-3.9; P = .03) were significantly associated with the risk of major amputation. In the subsets of patients with the most advanced WIfI stage of 3 to 4 (191 of 250; 76%) and patients with diabetes (185 of 250; 74%), the MAC score further stratified the risk of major amputation on univariate and multivariate analyses. CONCLUSIONS: The MAC score is a simple, practical tool and a strong independent predictor of major amputation in patients with CLTI. It provides novel clinical data that are currently unmeasured using any validated CLTI staging system. The MAC score is a promising standardized measure of inframalleolar disease burden that can be used in conjunction with the WIfI staging system to help improve outcomes stratification and determine the optimal treatment strategies for patients with CLTI.

Propensity score-matched analysis of 1-year outcomes of transcarotid revascularization with dynamic flow reversal, carotid endarterectomy, and transfemoral carotid artery stenting.

OBJECTIVE: Initial studies showed no significant differences in perioperative stroke or death between transcarotid artery revascularization (TCAR) and carotid endarterectomy (CEA) and lower stroke/death rates after TCAR compared with transfemoral carotid artery stenting (TFCAS). This study focuses on the 1-year outcomes of ipsilateral stroke or death after TCAR, CEA, and TFCAS. METHODS: All patients undergoing TCAR, TFCAS, and CEA between September 2016 and December 2019 were identified in the Vascular Quality Initiative (VQI) database. The latest follow-up was September 3, 2020. One-to-one propensity score-matched analysis was performed for patients with available 1-year follow-up data for TCAR vs CEA and for TCAR vs TFCAS. Kaplan-Meier survival and Cox proportional hazard regression analyses were used to evaluate 1-year ipsilateral stroke or death after the three procedures. RESULTS: A total of 41,548 patients underwent CEA, 5725 patients underwent TCAR, and 6064 patients underwent TFCAS during the study period and had recorded 1-year outcomes. The cohorts were well-matched in terms of baseline demographics and comorbidities. Among 4180 TCAR vs CEA matched pairs of patients, there were no significant differences in 30-day stroke, death, and stroke/death. However, TCAR was associated with a lower risk of 30-day stroke/death/myocardial infarction (2.30% vs 3.25%; relative risk, 0.71; 95% confidence interval [CI], 0.55-0.91; P = .008), driven by a lower risk of myocardial infarction (0.55% vs 1.12%; hazard ratio [HR], 0.49; 95% CI, 0.30-0.81; P = .004). At 1 year, no significant difference was observed in the risk of ipsilateral stroke or death (6.49% vs 5.68%; HR, 1.14; 95% CI, 0.95-1.37; P = .157). Among 4036 matched pairs in the TCAR vs TFCAS group, TCAR was also associated with lower risk of perioperative stroke or death compared with TFCAS (1.83% vs 2.55%; HR, 0.72; 95% CI, 0.54-0.96; P = .027). At 1 year, the risks of ipsilateral stroke or death of TCAR and TFCAS were comparable (6.07% vs 7.07%; HR, 0.85; 95% CI, 0.71-1.01; P = .07). Symptomatic status did not modify the association in TCAR vs CEA. However, asymptomatic patients had favorable outcomes with TCAR vs TFCAS at 1 year (HR, 0.78; 95% CI, 0.62-0.98; P = .033). CONCLUSIONS: In this propensity score-matched analysis, no significant differences in ipsilateral stroke/death-free survival were observed between TCAR and CEA or between TCAR and TFCAS. The advantages of TCAR compared with TFCAS seem to be mainly in the perioperative period, which makes it a suitable minimally invasive option for surgically high-risk patients with carotid artery stenosis. Larger studies, with longer follow-up and data on restenosis, are warranted to confirm the mid- and long-term benefits and durability of TCAR.

The influence of socioeconomic status on outcomes of lower extremity arterial reconstruction.

OBJECTIVE: Although it has been shown that patient socioeconomic status (SES) is associated with the surgical treatments chosen for severe peripheral arterial disease (PAD), the association between SES and outcomes of arterial reconstruction have not been well-studied. The objective of this study was to determine if SES is associated with outcomes following lower extremity arterial reconstruction. METHODS: Patients 40 years and older who had surgical revascularization for severe lower extremity PAD were identified in the Nationwide Readmissions Database, 2010 to 2014. Measures of SES including median household income (MHI) quartiles of patients' residential ZIP codes were extracted. Factors associated with repeat revascularization, subsequent major amputations, hospital mortality, and 30-day all-cause readmission were evaluated using multivariable regression analyses. RESULTS: Of the 131,529 patients identified, the majority (61%) were male, and the average age was 69 years. On unadjusted analyses, subsequent amputations were higher among patients in the lowest MHI quartile compared with patients in the highest MHI quartile (13% vs 10%; overall P < .001). On multivariable analyses, compared with patients in the lowest quartile, those in the highest quartile had lower amputation (adjusted odds ratio [aOR], 0.70; 95% confidence interval (CI), 0.63-0.77; overall P < .001) and readmission (aOR, 0.91; 95% CI, 0.84-0.99; overall P = .028) rates. However, subsequent revascularization (aOR, 1.04; 95% CI, 0.94-1.15) and mortality (aOR, 1.01; 95% CI, 0.79-1.28) rates were not different across the groups. CONCLUSIONS: Lower SES is associated with disproportionally worse outcomes following lower extremity arterial reconstruction for severe PAD. These data suggest that improving outcomes of lower extremity arterial reconstruction may involve addressing socioeconomic disparities.

Prevalence of chronic opioid use in patients with peripheral arterial disease undergoing revascularization.

OBJECTIVE: Opiate use, dependence, and the associated morbidity and mortality are major current public health problems in the United States. Little is known about patterns of opioid use in patients with peripheral arterial disease (PAD). The purpose of this study was to identify the prevalence of chronic preoperative and postoperative prescription opioid use in patients with PAD. A secondary aim was to determine the demographic, comorbid conditions, and operative characteristics associated with chronic opioid use. METHODS: Using a single-institution database of patients with PAD undergoing open or endovascular lower extremity intervention from 2013 to 2014, data regarding opiate use and associated conditions were abstracted for analysis. Patients were excluded if they did not live in North Carolina or surgery was not for PAD. Preoperative (PreCOU) and postoperative chronic opioid use (PostCOU) were defined as consistent opioid prescription filling in the 3 months before and after the index procedure, respectively. Opioid prescription filling was assessed using the North Carolina Controlled Substance Reporting System. Demographics, comorbid conditions, other adjunct pain medication data, and operative characteristics were abstracted from our institutional electronic medical record. Associations with PreCOU were evaluated using the t test, Wilcoxon test, or two-sample median test (continuous), or the χ2 or Fisher exact tests (categorical). RESULTS: A total of 202 patients undergoing open (108; 53.5%) or endovascular (94; 46.5%) revascularization for claudication or critical limb ischemia were identified for analysis. The mean age was 64.6 years, and 36% were female. Claudication was the indication for revascularization in 26.7% of patients, and critical limb ischemia was the indication in 73.3% of patients. The median preoperative ankle-brachial index (ABI) was 0.50. Sixty-eight patients (34%) met the definition for PreCOU. PreCOU was associated with female gender, history of chronic musculoskeletal pain, benzodiazepine use, and self-reported illicit drug use. Less than 50% of patients reported use of non-opiate adjunct pain medications. No association was observed between PreCOU and pre- or postoperative ABI, or number of prior lower extremity interventions. Following revascularization, the median ABI was 0.88. PreCOU was not associated with significant differences in postoperative complications, length of stay, or mortality. Overall, 71 patients (35%) met the definition for PostCOU, 14 of whom had no history of preoperative chronic opiate use. Ten patients with PreCOU did not demonstrate PostCOU. CONCLUSIONS: Chronic opiate use was common in patients with PAD with a prevalence of approximately 35%, both prior to and following revascularization. Revascularization was associated with a termination of chronic opiate use in less than 15% of patients with PreCOU. Additionally, 10% of patients who did not use opiates chronically before their revascularization did so afterwards. Patients with PAD requiring intervention represent a high-risk group with regards to chronic opiate use. Increased diligence in identifying opioid use among patients with PAD and optimizing the use of non-narcotic adjunct pain medications may result in a lower prevalence of chronic opiate use and its attendant adverse effects.

Intracranial Angioplasty with Enterprise Stent for Intracranial Atherosclerotic Stenosis: A Single-Center Experience and a Systematic Review.

BACKGROUND: The high rate of periprocedural complications for the endovascular stent procedure in the Stenting Versus Aggressive Medical Management Therapy for Intracranial Arterial Stenosis (SAMMPRIS) trial resulted in it being less recommended than medical therapy to treat intracranial atherosclerotic stenosis (ICAS). Because Enterprise stent use might reduce the incidence of complications in ICAS treatment compared to other frequently used stents, this paper evaluated the safety and effectiveness of the Enterprise stent for the treatment of ICAS. METHODS: We performed a comprehensive literature search for reports on intracranial angioplasty using the Enterprise stent for ICAS treatment from the earliest date available from each database to May 2020 for PubMed, EMBASE, Web of Science, Cochrane, and Clinical Trials databases. We also reviewed the single-center experience of the First Affiliated Hospital of Harbin Medical University. We extracted information regarding periprocedural complications, procedure-related morbidity, mortality, immediate angiographic outcome, and long-term clinical and angiographic outcomes, among others. Event rates were pooled across studies using random-effects or fixed-effects models depending on the heterogeneity. RESULTS: Five hundred fifty-seven patients with 588 lesions from seven studies, including the institutional series, were included in the analysis. The incidence of stroke or death within 30 days was 7.4% (95% confidence interval (CI), 5.5%-10.1%). The incidence of ischemic stroke or TIA in the territory of the qualifying artery beyond 30 days and during follow-up was 3.2% (95% CI, 1.1%-9.5%). The incidence of in-stent restenosis was 10.1% (95% CI, 4.6%-22.2%), and the incidence of symptomatic restenosis was 4.1% (95% CI, 1.7%-9.9%). CONCLUSIONS: Intracranial angioplasty utilizing the Enterprise stent for ICAS treatment was relatively safe and effective but required further verification using additional sources for evidence.

Changes in Neuroendovascular Procedural Volume During the COVID-19 Pandemic: An International Multicenter Study.

BACKGROUND AND PURPOSE: The effect of coronavirus disease 2019 (COVID-19) pandemic on performance of neuroendovascular procedures has not been quantified. METHODS: We performed an audit of performance of neuroendovascular procedures at 18 institutions (seven countries) for two periods; January-April 2019 and 2020, to identify changes in various core procedures. We divided the region where the hospital was located based on the median value of total number of COVID-19 cases per 100,00 population-into high and low prevalent regions. RESULTS: Between 2019 and 2020, there was a reduction in number of cerebral angiograms (30.9% reduction), mechanical thrombectomy (8% reduction), carotid artery stent placement for symptomatic (22.7% reduction) and asymptomatic (43.4% reduction) stenoses, intracranial angioplasty and/or stent placement (45% reduction), and endovascular treatment of unruptured intracranial aneurysms (44.6% reduction) and ruptured (22.9% reduction) and unruptured brain arteriovenous malformations (66.4% reduction). There was an increase in the treatment of ruptured intracranial aneurysms (10% increase) and other neuroendovascular procedures (34.9% increase). There was no relationship between procedural volume change and intuitional location in high or low COVID-19 prevalent regions. The procedural volume reduction was mainly observed in March-April 2020. CONCLUSIONS: We provided an international multicenter view of changes in neuroendovascular practices to better understand the gaps in provision of care and identify individual procedures, which are susceptible to change.

Do patients with minimal blunt thoracic aortic injury require thoracic endovascular repair?

INTRODUCTION: The optimal management of minimal blunt thoracic aortic injuries (BTAIs) remains controversial, with experienced centers using therapy ranging from medical management (MM) to thoracic endovascular aortic repair (TEVAR). METHODS: The Aortic Trauma Foundation registry was used to examine demographics, injury characteristics, management, and outcomes of patients with BTAI. RESULTS: Two hundred ninety-six patients from 28 international centers were analyzed (mean age, 44.5 years [SD, 18 years]; 76% [225/296] male; mean Injury Severity Score, 34 [SD, 14]). Blunt thoracic aortic injury was classified as Grade I, 22.6% (67/296); Grade II, 17.6% (52/296); Grade III, 47.3% (140/296); and Grade IV, 12.5% (37/296). Overall aortic-related mortality (ARM) was 4.7% (14/296). Among all deaths, 33% (14/42) were ARM. Open repair was required for only 2%, with most undergoing TEVAR (58.4%) or MM (28.0%). Thoracic endovascular repair complications occurred in 3.4% (6/173), most commonly Type 1 endoleak (2.3%; 4/173). Among patients with minimal aortic injury (Grades I and II), 59.7% (71/119) received MM, while 40.3% (48/119) underwent TEVAR. Two patients initially managed with MM required subsequent TEVAR for injury progression during initial hospital stay. No significant difference in ARM between MM and TEVAR was noted for Grades I and II injuries. CONCLUSION: A third of the trauma victims with BTAI succumb to ARM. Thoracic endovascular repair has replaced open repair but remains equivalent in outcomes to MM for minimal injuries. These data support MM of patients with minimal aortic injury. LEVEL OF EVIDENCE: Therapeutic study, level IV.

Management of cardiovascular emergencies during the COVID-19 pandemic.

BACKGROUND: It has been reported that patients attending the emergency department with other pathologies may not have received optimal medical care due to the lockdown measures in the early phase of the COVID-19 pandemic. METHODS: This was a retrospective study of patients presenting with cardiovascular emergencies to four tertiary regional emergency departments in western India during the government implementation of complete lockdown. RESULTS: 25.0% of patients during the lockdown period and 17.4% of patients during the pre-lockdown period presented outside the window period (presentation after 12 hours of symptom onset) compared with only 6% during the pre-COVID period. In the pre-COVID period, 46.9% of patients with ST elevation myocardial infarction underwent emergent catheterisation, while in the pre-lockdown and lockdown periods, these values were 26.1% and 18.8%, respectively. The proportion of patients treated with intravenous thrombolytic therapy increased from 18.4% in the pre-COVID period to 32.3% in the post-lockdown period. Inhospital mortality for acute coronary syndrome (ACS) increased from 2.69% in the pre-COVID period to 7.27% in the post-lockdown period. There was also a significant decline in emergency admissions for non-ACS conditions, such as acute decompensated heart failure and high degree or complete atrioventricular block. CONCLUSION: The COVID-19 pandemic has led to delays in patients seeking care for cardiac problems and also affected the use of optimum therapy in our institutions.

A Systematic Review of Procedural Outcomes in Patients With Proximal Common Carotid or Innominate Artery Disease With or Without Tandem Ipsilateral Internal Carotid Artery Disease.

OBJECTIVE: To establish 30 day and mid term outcomes in patients treated for significant stenoses affecting the proximal common carotid artery (CCA) or innominate artery (IA) with/without tandem disease of the ipsilateral internal carotid artery (ICA). METHODS: Systematic review of early and mid term outcomes in 1 969 patients from 77 studies (1960-2017) who underwent: (i) hybrid open retrograde angioplasty/stenting of the IA/proximal CCA plus carotid endarterectomy (CEA) in patients with tandem disease of the ipsilateral proximal ICA (n = 700); (ii) isolated open surgery to the IA or proximal CCA (no CEA) (n = 686); or (iii) an isolated endovascular approach to IA or proximal CCA stenoses (no CEA) (n = 583). RESULTS: In the hybrid group with tandem disease (66% involving proximal CCA), the 30 day death/stroke was 3.3%, with a late ipsilateral stroke rate of 3.3% at a median six years follow up. Late re-stenosis was 10.5% for proximal CCA/IA and 4.1% for the ICA. In the isolated open surgery group (78% involving the IA), the 30 day death/stroke was 7%, with a late ipsilateral stroke rate of 1% at a median 12 years follow up. Late re-stenosis within aortic bypasses was 2.6%. In the isolated endovascular group (52% IA, 47% proximal CCA), the majority of procedures were done percutaneously (84%), with a 30 day death/stroke rate of 1.5%. Late ipsilateral stroke was 1% at a median four years follow up, with a re-stenosis rate of 9%. CONCLUSION: Procedural risks were higher following isolated open surgical interventions involving the proximal CCA/IA, compared with proximal lesions treated by isolated angioplasty/stenting, or in tandem with CEA. This higher morbidity/mortality may, however, reflect a greater proportion of innominate (vs. proximal CCA) lesions in open surgical series, changes in patient selection, time dependent evolution of medical interventions, and publication bias. The available data were limited and related to very different patient groups and management strategies spanning 57 years. Caution is raised, particularly for open surgery IA and CCA surgery, and for any procedures in asymptomatic patients. In symptomatic patients, the data cautiously support an "endovascular first" strategy for isolated proximal CCA/IA lesions and a hybrid approach for tandem proximal CCA/IA and ICA stenoses.

Outcomes for Angioplasty and Bypass Lower Limb Revascularisation Procedures for Limb Salvage in England: Findings From the Getting It Right First Time Programme.

OBJECTIVE: The aim of this study was to investigate outcomes for lower limb revascularisation for limb salvage within the National Health Service (NHS) in England. METHODS: This was a retrospective observational study of administrative data. Data were extracted from the Hospital Episodes Statistics database for England. Data were included for a seven year period (1 April 2011-31 March 2018 inclusive) for all patients aged ≥ 18 years receiving surgery for peripheral arterial occlusive disease. Data were extracted for patient age, sex and frailty level, the NHS trusts undertaking the procedure, the technique used (angioplasty, bypass, endarterectomy, or hybrid), the mode of admission (elective or emergency), the surgical speciality, the financial year of admission, length of hospital stay during the procedure, subsequent emergency re-admission, revascularisation procedures within 30 days and subsequent amputation and mortality within one year and within five years. The primary outcome was one year amputation free survival. For analysis, data were separated into diabetic and non-diabetic patients. Multilevel modelling was used to adjust for hierarchy and observed confounding when investigating outcomes. RESULTS: Data were available for 98 109 procedures across 124 hospital trusts. For non-diabetic patients (odds ratio 1.142, 95% confidence interval 1.068-1.222), one year amputation free survival was higher for angioplasty than for bypass. For diabetic patients, there was no difference in the primary outcome. One year amputation rates, 30 day emergency re-admission rates, and length of stay were all lower for angioplasty, and 30 day revascularisation rates were lower for bypass for both diabetic and non-diabetic patients. CONCLUSION: Outcomes were generally better for angioplasty than for bypass surgery for lower limb revascularisation for both diabetic and non-diabetic patients. The findings should be interpreted with caution given the likely different clinical presentations of those selected for each procedure. Future clinical trials may provide more definitive data.

The Current Status of Endovascular Treatment for Extracranial Steno-occlusive Diseases in Japan: Analysis Using the Japanese Registry of Neuroendovascular Therapy 3 (JR-NET3).

Endovascular treatment of extracranial steno-occlusive lesions is an alternative to direct surgery. There is no consensus regarding the natural course and standard treatment of these lesions. The aim of this study was to identify the current status of endovascular treatment for extracranial steno-occlusive lesions. A total of 1154 procedures for extracranial steno-occlusive lesions, except for internal carotid artery stenosis, were collected from the Japanese Registry of Neuroendovascular Therapy 3 (JR-NET3). Atherosclerotic lesions were most frequent (1021 patients, 88.5%). Endovascular treatment was performed for 456 (39.5%) patients with subclavian artery, 349 (30.2%) with extracranial vertebral artery, 172 (14.9%) with the origin of common carotid artery, and 38 (3.3%) with innominate artery stenosis; the overall technical success rate was 98.0%. Percutaneous transluminal angioplasty was performed in 307 patients (26.6%) and stenting in 838 (72.6%). An embolic protection device (EPD) was used in 571 patients (49.5%), and procedure under general anesthesia was performed in 168 (14.6%). Preoperative antiplatelet therapy was administered in 1091 procedures (94.5%). A good outcome was obtained for 962 patients (83.4%). Complications were observed in 89 patients (7.7%). The procedure under general anesthesia was statistically significant factors (P <0.01), and also after multivariable adjustment (odds ratio 2.29; 95% confidence interval 1.25-4.17; P <0.01). Comparisons between JR-NET3 and previous cohorts (JR-NET1&2), the utilization of EPD and complications increased significantly, and the type of antiplatelet therapy changed markedly. Based on the results of this study, endovascular treatment for extracranial steno-occlusive lesions is relatively safe. Further prospective studies are necessary to validate the beneficial effects.

Indicadores hospitalares de acesso e efetividade e crise econômica: análise baseada nos dados do Sistema Único de Saúde, Brasil e estados da região Sudeste, 2009-2018 / Access and effectiveness inpatient care indicators and economic crisis: analysis based on the Brazilian Unified Health System data, Brazil and Southern Brazil states, 2009-2018

Resumo No contexto de crise e restrições de recursos é razoável supor o agravamento de fragilidades do Sistema Único de Saúde (SUS), como desigualdades regionais, subfinanciamento e problemas na qualidade do cuidado. Este estudo explorou a aplicação de indicadores de acesso e efetividade, facilmente compreensíveis e calculados, passíveis de refletir a crise na rede hospitalar. Cinco indicadores extraídos do Sistema de Informações Hospitalares, relativos ao Brasil e a estados da Região Sudeste, foram analisados no período de 2009-2018: internações resultantes em morte; internações cirúrgicas resultantes em morte; cirurgias eletivas no total das internações cirúrgicas; próteses de quadril na população de idosos; e angioplastias na população de 20 anos ou mais. Utilizaram-se gráficos de controle estatístico para a comparação dos indicadores entre estados, antes e a partir de 2014. No Brasil, as mortes hospitalares tiveram um leve crescimento enquanto que as mortes cirúrgicas uma queda; as cirurgias eletivas e próteses de quadril também diminuíram. No Sudeste, o Rio de Janeiro apresentou os piores resultados, em especial a queda de cirurgias eletivas. Os resultados ilustram o potencial dos indicadores para monitorar efeitos da crise sobre o cuidado hospitalar.

Abstract In the context of crisis and resource constraints, it is reasonable to assume the deteriorated weaknesses of the Unified Health System (SUS), such as regional inequalities, underfinancing, and care quality issues. This study explored the application of easily comprehensible and calculated access and effectiveness indicators that could reflect the hospital network crisis. Five indicators extracted from the Hospital Information System, related to Brazil and states of the Southeastern region, were analyzed in the 2009-2018 period: hospitalizations resulting in death; surgical hospitalizations resulting in death; elective surgeries in the total of surgical hospitalizations; hip prostheses in the senior population; and angioplasties in the population aged 20 years and over. Statistical control charts were used to compare indicators between states, before and from 2014. In Brazil, overall hospital deaths had a slight increase while surgical deaths declined; elective surgeries and hipprosthesis also decreased. In Southeastern Brazil, Rio de Janeiro was the worst performer, especially the decrease of the elective surgeries. The results illustrate the potential of indicators to monitor crisis effects on hospital care.

In the context of crisis and resource constraints, it is reasonable to assume the deteriorated weaknesses of the Unified Health System (SUS), such as regional inequalities, underfinancing, and care quality issues. This study explored the application of easily comprehensible and calculated access and effectiveness indicators that could reflect the hospital network crisis. Five indicators extracted from the Hospital Information System, related to Brazil and states of the Southeastern region, were analyzed in the 2009-2018 period: hospitalizations resulting in death; surgical hospitalizations resulting in death; elective surgeries in the total of surgical hospitalizations; hip prostheses in the senior population; and angioplasties in the population aged 20 years and over. Statistical control charts were used to compare indicators between states, before and from 2014. In Brazil, overall hospital deaths had a slight increase while surgical deaths declined; elective surgeries and hipprosthesis also decreased. In Southeastern Brazil, Rio de Janeiro was the worst performer, especially the decrease of the elective surgeries. The results illustrate the potential of indicators to monitor crisis effects on hospital care.

No contexto de crise e restrições de recursos é razoável supor o agravamento de fragilidades do Sistema Único de Saúde (SUS), como desigualdades regionais, subfinanciamento e problemas na qualidade do cuidado. Este estudo explorou a aplicação de indicadores de acesso e efetividade, facilmente compreensíveis e calculados, passíveis de refletir a crise na rede hospitalar. Cinco indicadores extraídos do Sistema de Informações Hospitalares, relativos ao Brasil e a estados da Região Sudeste, foram analisados no período de 2009-2018: internações resultantes em morte; internações cirúrgicas resultantes em morte; cirurgias eletivas no total das internações cirúrgicas; próteses de quadril na população de idosos; e angioplastias na população de 20 anos ou mais. Utilizaram-se gráficos de controle estatístico para a comparação dos indicadores entre estados, antes e a partir de 2014. No Brasil, as mortes hospitalares tiveram um leve crescimento enquanto que as mortes cirúrgicas uma queda; as cirurgias eletivas e próteses de quadril também diminuíram. No Sudeste, o Rio de Janeiro apresentou os piores resultados, em especial a queda de cirurgias eletivas. Os resultados ilustram o potencial dos indicadores para monitorar efeitos da crise sobre o cuidado hospitalar.

Incidence and treatment of congenital coronary artery anomalies.

BACKGROUND: Congenital coronary arteries anomalies are a rare entity. Although their identification started in the 60th, there is a lack of data concerning their frequency and clinical significance in Tunisia. AIM: To characterize clinical and imaging features and mid-term follow up data of congenital coronary artery anomalies in a population of Tunisian adults. METHODS: We reviewed the records of 6358 adult patients who underwent coronary angiography between 2009-2015 years in Mongi Slim hospital La Marsa, Tunisia. Multidetector computed tomography was performed on all patients diagnosed having these anomalies and Angelini classification was used for their arrangement. Patients, having intramural coronary artery, were excluded from this study. RESULTS: Thirteen patients had congenital coronary arteries anomalies (seven females and six males). Ten had anomalies of origination and course while the others had anomalies of coronary termination. The right coronary artery was the vessel involved most frequently. It originated from an anomalous coronary ostium in four patients and a unique right coronary artery was reported in one case. An anomalous left main coronary artery was seen in four cases. One patient had the left anterior descending artery originating from the right Valsalva sinus. Four patients underwent coronary revascularization, one died before the intervention and the remainder received medical management. The mean follow up was 54.1±20 months. CONCLUSION: Congenital coronary arteries anomalies have a low incidence in adults. Coronary revascularization is actually indicated in anomalous aortic origin with inter aorto-pulmonary course.

Skin Hydration Level as a Predictor for Diabetic Wound Healing: A Retrospective Study.

BACKGROUND: In the diabetic foot, the skin may crack and develop fissures, potentially increasing vulnerability to ulceration and infection. Therefore, maintaining adequate skin hydration may be crucial for diabetic wound healing. However, no clinical study has addressed this issue. This study aimed to determine and compare the effect of the skin hydration level on diabetic wound healing with that of the tissue oxygenation level, which is recognized as the most reliable parameter in predicting diabetic wound healing. METHODS: This retrospective study included 263 diabetic patients with forefoot ulcers. Skin hydration and transcutaneous oxygen pressure data collected before and after percutaneous transluminal angioplasty were analyzed. Skin hydration and tissue oxygenation were graded as poor, moderate, or acceptable. Wound healing outcomes were graded as healed without amputation, minor amputation, or major amputation. Wound healing outcomes were compared using four parameters: skin hydration at baseline, transcutaneous oxygen pressure at baseline, post-percutaneous transluminal angioplasty skin hydration, and post-percutaneous transluminal angioplasty transcutaneous oxygen pressure. RESULTS: Each of the four parameters exhibited statistically significant correlations with wound healing outcomes. In the concurrent analysis of both skin hydration and transcutaneous oxygen pressure, skin hydration was a dominant parameter (p = 0.0018) at baseline, whereas transcutaneous oxygen pressure was a dominant parameter (p < 0.0001) following percutaneous transluminal angioplasty. CONCLUSIONS: Skin hydration level might be a useful predictor for diabetic wound healing. In particular, the skin hydration level before recanalization was found to be superior to transcutaneous oxygen pressure in predicting wound healing. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

Safety of Early Carotid Artery Stenting for Symptomatic Stenosis in Daily Practice.

OBJECTIVE/BACKGROUND: In 2006, the American Heart Association recommended that for preference carotid endarterectomy (CEA) or, alternatively, carotid angioplasty and stenting (CAS) for symptomatic carotid artery stenosis should ideally occur within 14 days of an ischaemic event. The aim was to determine the safety of CAS according to those recommendations in daily practice. METHODS: A retrospective analysis was performed of all consecutive patients (2000-16), with ipsilateral carotid symptoms who underwent CAS for extracranial carotid stenosis ≥70%, who were previously included in a prospective database. Thirty day morbidity was assessed (any stroke without transient ischaemic attack [TIA]/amaurosis fugax), along with mortality of the procedure in the early (≤14 days after stroke onset) and delayed phases (15-180 days after stroke onset). Patients who received CAS and/or mechanical thrombectomy for acute ischaemic stroke treatment were not included. RESULTS: In total, 1227 patients with symptomatic carotid stenosis who underwent CAS were identified. Early and delayed CAS was performed in 291 and 936 patients, respectively. Morbidity (any stroke) and mortality was 2.2% (n = 27) in the whole cohort (n = 8 [2.7%] in early vs. n = 19 [2%] in delayed CAS; p = .47). There were no differences in morbidity between early and delayed CAS regarding TIA (n = 15 vs. 36 [5.2% vs. 3.9%]; p = .33), minor stroke (n = 4 vs. 5 [1.4% vs. 0.5%]; p = .14), or major stroke (n = 2 vs. 6 [0.7% vs. 0.6%]; p = .59). Two patients (0.7%) died after early CAS and eight (0.9%) after delayed CAS (p = .56). CONCLUSION: CAS may be safely performed in the early phase after an ischaemic stroke with low clinical complication rates. Further studies are needed to validate CAS safety conducted even earlier in the acute phase of ischaemic stroke.
