“…Three independent risk variables for restenosis were male sex, smoking, and hyperlipidemia. Thus, it is vital to monitor hyperlipidemia, and regular ultra-sonographic follow-up is advised, particularly for male patients who smoke now or in the past [ 30 ]. Stroke is a growing public health burden since it can lead to long-term disability.…”

Carotid stenosis (CS) is a buildup of atherosclerotic plaque within the artery leading to a wide range of symptoms, from mild symptoms, including blurred vision and confusion, to much more life-threatening presentations, including paralysis due to stroke. The presentation is insidious, with symptoms exhibiting predominantly at severe stenosis; hence the emphasis is placed on the importance of early diagnosis, treatment, and lifestyle modifications. CS is seen undergoing almost the same pathogenesis of any atherosclerotic plaque formation, from endothelial damage of the artery lumen to the formation of a fibrous cap with a foam cell, lipid-filled core. The findings of our review article were consistent with the recent literature, depicting that comorbid hypertension, diabetes, and chronic kidney disease (CKD), and lifestyle aspects, including smoking and diet, played the most salient role in plaque development. Among several imaging modalities, duplex ultrasound (DUS) imaging is the widely preferred method in clinical practice. Carotid endarterectomy (CEA) and carotid stenting are the primarily advocated procedures for symptomatic severe stenosis, with similar long-term outcomes. Although, earlier clinical trials showed promising results in mitigating the risk of stroke among asymptomatic severe CS with surgical intervention. However, recent advancements have shifted the focus to medical management alone due to comparable results among the asymptomatic population. Both surgical and medical regimens are beneficial in treating patients, but it is still an ongoing debate as to which is predominantly superior. The currently advancing trials and research will help elucidate definitive guidelines. However, the massive impact of lifestyle modifications advocates some degree of individualized multidisciplinary management strategies.

“…Stent material selection, carotid artery stenosis criteria, follow-up time and, hospital medical level are also important factors affecting the efficacy. Organ tissue disorder is one of the serious problems that threaten human health, and the common treatment methods are organ transplantation and tissue repair (6). The clinical effect of artificial device repair is excellent, but the natural donor source for transplantation and repair is very limited.…”

This work was developed to explore the adoption value of bacterial cellulose (BC) and heparin (He) combined with novel nano bio-vascular stents in carotid artery stent implantation, as well as the nursing methods and effects during the perioperative period. Based on the BC artificial blood vessel preparation method, the BC-He novel nano bio-vascular stent was fabricated after the modification of the medium method. Infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), and X-ray electron diffraction (XRD) were performed to analyze the crystal structure and chemical structure of the material. In addition, scanning electron microscope (SEM) and transmission electron microscope (TEM) were employed to observe the micro-morphology of the stent. The mechanical properties and thermal stability of the materials were also characterized. Then, with 98 patients undergoing carotid artery stenting (CAS) as the research object, BC-He novel nano bio-vascular stent was applied to treat patients with arterial stenosis. According to different nursing methods, patients were assigned to the conventional nursing group (group A) and perioperative nursing group (group B). The postoperative complications, nursing effect, and satisfaction degree of the two groups were compared. It turned out that the BC-He novel nano bio-vascular stent was a kind of micro-mesh structure. There were characteristic absorption peaks of BC and He in BC-He, and there were N and S from He. Moreover, it also contained BC and He characteristic diffraction peaks, its tensile strength was significantly lower than BC, and its thermal stability was higher than BC. The preoperative carotid artery stenosis ranged from 50 % to 75 %, and the postoperative stenosis rate of restenosis patients treated with BC-He novel nano bio-vascular stent was less than 10 %. In addition, there were 92 patients (93.88 %) whose symptoms improved or markedly improved within 1 to 2 weeks after the operation, and 78 patients (79.6 %) had improved hemodynamic parameters. The incidence of postoperative complications in group A was dramatically superior to that in group B (P < 0.05). The total effective rate of nursing care and the degree of nursing satisfaction in group B were better than those in group A (P < 0.05). In short, BC-He novel nano bio-vascular stent had good mechanical properties and thermal stability, which was a safe and effective material for the treatment of carotid artery stenosis. In addition, the perioperative nursing method was effective and was of certain clinical adoption value.

“…Stenosis or occlusion of internal carotid artery (ICA) is an important cause of chronic cerebral ischemia [1][2][3][4]. The degree of ICA stenosis is closely related to the changes of cerebral hemodynamics [5][6][7][8].…”

BackgroundThe aim of this study was to explore the influence of different input arteries on the parameters of computed tomography (CT) perfusion imaging for patients with different degree of stenosis of internal carotid artery (ICA).Material/MethodsForty patients were enrolled in the present study and divided into mild, moderate, severe stenosis and occlusion groups respectively with each 10 patients in each group. In reconstruction of cerebral CT perfusion (CTP) images, each raw perfusion image was reconstructed 3 times based on different reference input artery, including bilateral middle cerebral artery (MCA) and basilar arteries (BA). Region of interest (ROI) was drawn in the central territories of bilateral anterior cerebral artery, middle cerebral artery and posterior cerebral artery. And regional cerebral blood flow (rCBF) regional cerebral blood volume (rCBV), mean transit time (MTT), time to peak (TTP) and delay time (DT) were obtained from those ROI corresponding perfusion images.ResultsIn patients with mild and moderate ICA stenosis, there was no significant difference of perfusion parameters based on different input arteries (P>0.05). However, in severe ICA stenosis and occlusion CBF, MTT, and DT were significant different in affect side of the MCA group compared to the others (P<0.05).ConclusionsLarge intracranial artery can be selected as the input artery for patients with mild to moderate ICA stenosis, while for patients with severe stenosis and occlusion of ICA, the contra lateral middle cerebral artery or basilar artery would be better choice.
