Intercostal artery's access for type II endoleak embolization.

Endoleaks represent a main issue of endovascular approach of thoracic aorta diseases and their treatment continue to be challenging. According to some authors, type II endoleaks sustained by intercostal arteries should not be treated because of the technical difficulties. However, the persistence of a pressurized aneurysmal may confer an ongoing risk of enlargement and/or aortic rupture. We describe the successful treatment of type II endoleak in 2 patients with an intercostal artery's access. In both cases, the endoleak was discovered during follow-up and was treated with its direct coil embolization under local anaesthesia.

Guideline on carotid surgery for stroke prevention: updates from the Italian Society of Vascular and Endovascular Surgery. A trend towards personalized medicine.

BACKGROUND: This guideline (GL) on carotid surgery as updating of "Stroke: Italian guidelines for Prevention and Treatment" of the ISO-SPREAD Italian Stroke Organization-Group, has recently been published in the National Guideline System and shared with the Italian Society of Vascular and Endovascular Surgery (SICVE) and other Scientific Societies and Patient's Association. METHODS: GRADE-SIGN version, AGREE quality of reporting checklist. Clinical questions formulated according to the PICO model. Recommendations developed based on clinical questions by a multidisciplinary experts' panel and patients' representatives. Systematic reviews performed for each PICO question. Considered judgements filled by assessing the evidence level, direction, and strength of the recommendations. RESULTS: The panel provided indications and recommendations for appropriate, comprehensive, and individualized management of patients with carotid stenosis. Diagnostic and therapeutic processes of the best medical therapy, carotid endarterectomy (CEA), carotid stenting (CAS) according to the evidences and the judged opinions were included. Symptomatic carotid stenosis in elective and emergency, asymptomatic carotid stenosis, association with ischemic heart disease, preoperative diagnostics, types of anesthesia, monitoring in case of CEA, CEA techniques, comparison between CEA and CAS, post-surgical carotid restenosis, and medical therapy are the main topics, even with analysis of uncertainty areas for risk-benefit assessments in the individual patient (personalized medicine [PM]). CONCLUSIONS: This GL updates on the main recommendations for the most appropriate diagnostic and medical-surgical management of patients with atherosclerotic carotid artery stenosis to prevent ischemic stroke. This GL also provides useful elements for the application of PM in good clinical practice.

Anesthetic management of carotid endarterectomy: an update from Italian guidelines.

BACKGROUND AND AIMS: In order to systematically review the latest evidence on anesthesia, intraoperative neurologic monitoring, postoperative heparin reversal, and postoperative blood pressure management for carotid endarterectomy. The present review is based on a single chapter of the Italian Health Institute Guidelines for diagnosis and treatment of extracranial carotid stenosis and stroke prevention. METHODS AND RESULTS: A systematic article review focused on the previously cited topics published between January 2016 and October 2020 has been performed; we looked for both primary and secondary studies in the extensive archive of Medline/PubMed and Cochrane library databases. We selected 14 systematic reviews and meta-analyses, 13 randomized controlled trials, 8 observational studies, and 1 narrative review. Based on this analysis, syntheses of the available evidence were shared and recommendations were indicated complying with the GRADE-SIGN version methodology. CONCLUSIONS: From this up-to-date analysis, it has emerged that any type of anesthesia and neurological monitoring method is related to a better outcome after carotid endarterectomy. In addition, insufficient evidence was found to justify reversal or no-reversal of heparin at the end of surgery. Furthermore, despite a low evidence level, a suggestion for blood pressure monitoring in the postoperative period was formulated.

The relation between neutrophil/lymphocyte and platelet/lymphocyte ratios with mortality and limb amputation after acute limb ischaemia.

OBJECTIVE: Acute limb ischaemia is still considered a significant event, with considerable early- and long-term amputation and mortality risk. Our study aims to investigate the predictive role of pre-operative neutrophil/lymphocyte and platelet/lymphocyte ratios in terms of mortality and amputation risk in patients with acute limb ischaemia. METHODS: Pre-operative blood samples of all patients admitted with acute limb ischaemia were used to calculate neutrophil/lymphocyte and platelet/lymphocyte ratios. Population was subdivided into quartiles by platelet/lymphocyte ratio and neutrophil/lymphocyte ratio values, and Kaplan-Meier life tables were obtained for overall survival and limb salvage. The optimal neutrophil/lymphocyte ratio and platelet/lymphocyte ratio cut-offs were obtained from receiver operating characteristic curves with all-cause mortality and all kinds of amputation. Stepwise multivariate analysis was performed in order to identify independent risk and protective factors for mortality and amputations. RESULTS: A total of 168 patients were included in the analysis. Receiver operating characteristic curves identified cut-off values for neutrophil/lymphocyte ratio and platelet/lymphocyte ratio: neutrophil/lymphocyte ratio ≥5.57 for mortality; neutrophil/lymphocyte ratio ≥6.66 and platelet/lymphocyte ratio ≥269.9 for all amputations. Kaplan-Meier analysis revealed that survival rate in group neutrophil/lymphocyte ratio <5.57 was 83.4%, 78.9%, 73.7%, and 59.8%, respectively, at 12, 24, 36, and 48 months; in neutrophil/lymphocyte ratio ≥5.57 group was 62.4%, 51.3%, 47.8, and 43.7%, respectively (p < 0.0001). Freedom from all amputations was significantly higher in case of neutrophil/lymphocyte ratio and platelet/lymphocyte ratio below the identified cut-off values (p < 0.0001). Neutrophil/lymphocyte ratio and platelet/lymphocyte ratio were found as independent risk factors. CONCLUSION: Neutrophil/lymphocyte ratio and platelet/lymphocyte ratio are reliable markers for stratification of mortality and limb amputations in patients with acute limb ischaemia. The inexpensive nature and ready availability of these biomarkers' values reinforced their usefulness in everyday clinical practice.

Multiple cavernous malformation syndrome: a casual diagnosis during carotid revascularization procedure.

INTODUCTION: Familial cerebral cavernous malformations (FCCM) are a rare condition characterized by the multiple presences of cavernous malformations located in the central nervous system. CASE DESCRIPTION: We present a case of FCCM incidental diagnosis in a 71-year-old male patient who underwent carotid artery stenting for high-grade carotid artery disease and subsequent reintervention for severe stent restenosis, determining neurological deficit. FCCM diagnosis was made due to the presence of hundreds of cavernous malformations located both in supra- and sub-tentorial regions highlighted by magnetic resonance and confirmed by genetic test for the mutation of the gene KRIT1, inherited also by his son.

Early and Long-Term Outcomes of Carotid Stenting and Carotid Endarterectomy in Women.

Background: The role of carotid revascularization in women remains intensely debated because of the lower benefit and higher perioperative risks concerning the male counterpart. Carotid artery endarterectomy (CEA) and stenting (CAS) represent the two most valuable stroke prevention techniques due to large vessel disease. This study investigates the early and late outcomes in female sex in a real-world everyday clinical practice. Methods: Data were retrospectively analyzed from a single-center database prospectively compiled. A total of 234 procedures, both symptomatic and asymptomatic, were identified (98 CEAs and 136 CASs). Perioperative risks of death, cerebral ischemic events, and local complications were analyzed and compared between the two groups. Long-term outcomes were evaluated in overall survival, freedom from ipsilateral stroke/transient ischemic attack, and freedom from restenosis (>50%) and reintervention. Results: Women who underwent CAS and CEA did not differ in perioperative ischemic cerebral events (2.2 vs. 0%, p = 0.26) and death (0.8 vs. 0%, p = 1). Other perioperative and 30-day outcomes were similarly distributed within the two groups. Kaplan-Meier curves between CAS and CEA groups highlighted no statistical differences at 6 years in overall survival (77.4 vs. 77.1%, p = 0.47) of ipsilateral stroke/transient ischemic attack (94.1 vs. 92.9%, p = 0.9). Conversely, significant differences were showed in 6 years freedom from restenosis (93.1 vs. 83.3%, p = 0.03) and reinterventions (97.7 vs. 87.8%, p = 0.015). Conclusion: Our results revealed that both CEA and CAS have acceptable perioperative risk in women. Long-term outcomes highlighted favorable indications for both procedures, especially for CAS, which seemed to be an excellent alternative to CEA in female patients when performed by well-trained operators.

The Limitations of Social Behaviour Imposed by CoVid-19 Impacted the Perception and the Evolution of Peripheral Arterial Disease Negatively.

BACKGROUND: The novel acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic imposed a national lockdown at the beginning of 2020. People faced social distancing, being forced to stay at home. Peripheral arterial disease (PAD) typically influences life habits and psycho-social relationship. It is now questionable how PAD can be affected by changes in lifestyle imposed by the Sars-CoV-19 Pandemic. This study's main objective is to evaluate how the limitations of social behavior set by Sars-CoV-19 Pandemic impact the perception and evolution of the disease in a group of patients with a diagnosed PAD. METHODS: The changes in the in the perception and the evolution of the PAD were evaluated by comparing results of a modified VascuQol-6 quality of life (QoL) survey referring to the time frame defined "No-Sars-CoV-2 period" (from July to December 2019) with results referring to the time frame defined "Sars-CoV-2 period" (from January to June 2020). An overall score (range 4-60) was calculated, and a comparison between the two period studies was reported. Receiver Operating Characteristics (ROC) Curves evaluated a delta value for each patient with revascularization of lower limb peripheral arteries. Optimal cut-offs were chosen based on their specificity, sensitivity. RESULTS: One-hundred-two PAD patients gave their informed consent to take part in the study. A significant general worsening of patients PAD perception in the Sars-CoV-2 period was recorded for the following items: lower limbs health status perception; overall activity limitation; walking ability limitation; overall daily walking distance; lower limbs fatigue perception; concerns about PAD worsening; pain discomfort (P < 0.05). The pain intensity changed from 4.7 ± 2.9 in the No-Sars-CoV-2 period to 6.3 ± 2.9 in the Sars-CoV-2 period significantly (P < 0.0001), even though analgesic drug intake did not increase considerably in Sars-CoV-2 period (P = 0.15). The overall score was 20.3 ± 7.4 for the No-Sars-CoV-2 period and 27.4 ± 7.6 in the Sars-CoV-2 period (P = 0.0001). The ROC curve built to analyze the relation between Delta-score and the need for revascularization identifies a cut-off > 8.5 (Area Under the Curve 0.5436; CI 95% 0.4252 to 0.6620) with a sensitivity and specificity respectively of 52.6% (CI 95% 37.26-67.52%) and 65.6% (CI 95% 53.40-76.08%). CONCLUSIONS: Patients with PAD were significantly hit by all the restrictions and the social limitations imposed to reduce the Sars-CoV-19 virus diffusion. Our study confirms that the perception and the evolution of PAD were significantly affected during the "Sars-CoV-2 period".

Clinical considerations and recommendations for OCT-guided carotid artery stenting.

Introduction: Optical Coherence Tomography (OCT) is an intravascular imaging providing high-resolution images of morphological features of arterial wall. Nowadays, OCT is an accepted intravascular modality to study coronary arteries, stent implantation, and vessel injury. In the last decade, an increasing interest have been focused on the application of OCT in carotid arteries.Areas covered: Literature evidence in the application of OCT in carotid arteries still remains debated. So far, OCT has been used as a research tool, aiming to evaluate atherosclerotic plaques' features and stents' behavior after implantation. This paper is intended to summarize clinical evidences and practices in the use of OCT in carotid arteries district and during CAS procedures. Literature review was completed via Pubmed search using Keywords.Expert opinion: CAS is a safe and effective procedure when performed by trained physicians with a tailored approach. In this scenario, ambiguous pictures at ultrasound, angiography, and IVUS might be clarified using OCT.By providing unprecedented microstructural information on atherosclerotic plaques, OCT may identify the features of vulnerable carotid plaque and, by identifying possible defects after stent implantation as malapposition and plaque prolapse, it may help the tailoring approach to CAS.
