Percutaneous Suture - Closure Device Used for Iatrogenic Carotid Artery Injury Management: Case Report and Review of Literature.

An unusual yet critical venous catheter insertion complication is an accidental carotid artery fracture. Hemostasis can't be achieved by manual compression; therefore, surgical or endovascular therapy remains the primarystay for accidental carotid artery injury. In other vascular beds, the use of vascular closure systems is unusual.

Relationship Between Serum Uric Acid and Carotid Plaque in Patients With Coronary Artery Disease by Sex and Blood Pressure Status.

The aim of this research was to investigate the sex difference and effects of blood pressure on patients with coronary heart disease, as shown by serum uric acid and carotid plaque. Patients with CHD who have CHD were based on logistic regression to investigate the effect of sex and BP on the relationship between SUA levels and carotid plaque. SUA levels were highly correlated with the presence of carotid plaque in various BP states, as shown by the BP of group A.

Predictive Factors for Stroke and TIA Following Carotid Artery Stenting.

Purpose Carotid artery stenting is a safe and minimally invasive method for the treatment of extracranial carotid artery stenosis. Following CAS to identify high-risk patients and increase the safety of CAS in this population, the present study sought to investigate independent risk factors to predict cerebrovascular events following CAS to identify high-risk patients and increase the safety of CAS. Materials and methods HISPANIAS is a national prospective multicenter research that included 14 hospitals that obtained patient records from patients who underwent CAS. Cerebrovascular disorders occurred in 42 patients, including TIA in 24 patients and stroke in 18 patients. Female sex and diabetes were the key independent clinical predictors of stroke/TIA identified by logistic regression. Among the remaining events, diabetic women had a larger number of events concentrated in the first days after the intervention, according to a Survival analysis. Implication of clinical Carotid artery stenosis Treatment is a simple and minimally invasive procedure for the treatment of extracranial carotid artery stenosis. Although CAS has been regarded as a reliable and safe method, some studies have found that CAS has been correlated with a higher risk of procedure-related strokes. Following CAS, cereebrovascular complications following CAS remain a significant problem and a challenge to these patients' care. According to our study, the combination of female sex and diabetes is reportedly lead to a drastically different result, with a greater number of events concentrated in the first days.

Rupture of the internal carotid artery pseudoaneurysm resulting from fungal sinusitis.

Although aneurysm has been linked to fungi infection, including Aspergillus, is rare, there are reports of internal carotid artery aneurysm formation as a result of fungal sinusitis. Performing endoscopic sinus surgery prior to the embolization procedure may have increased the risks of widespread intraoperative bleeding and mortality. Although the treatment scheme for fungal internal carotid artery aneurysms is uncertain, this case illustrates the use of embolization therapy followed by endoscopic debridement and antifungal therapy to treat a pseudoaneurysm of the internal carotid artery caused by fungal sinusitis.

Current Treatment Results of Intracranial Carotid Artery Dissection Causing Cerebral Ischemia: A Japanese Nationwide Survey.

A rare yet important cause of cerebral infarction in children and adolescents is intracranial carotid artery dissection, which results in cerebral ischemia. Patients within two weeks after ischemic onset due to intracranial carotid artery dissection causing cerebral ischemia treated between January 2015 and December 2020 were seen within 35 neurosurgical centers in total. During the initial therapy, patients with stenotic dissection were significantly more likely to experience apny than those with occlusive dissection. In addition, patients with moderate to moderately fetal impairments on admission had poorer outcomes at discharge more often than those with mild neurological deficits on admission. No surgical problems or further aggravation were noted after intervention. Patients with intracranial carotid dissection causing cerebral ischemia and causing chronic ischemic pain were likely to more deterioration, and endovascular therapy has successfully improved or prevented aggravation.

Mechanical Thrombectomy for Acute Common Carotid Artery Occlusion.

Mechanical thrombectomy is the most common treatment for acute large occlusion of the cerebral artery. We document our endovascular procedure and the clinical results in seven consecutive patients who underwent MT for CCA thrombi from September 2016 to April 2021. Their mean National Institutes of Health Stroke Scale score was 20. 0, and the mean diffusion-weighted imaging Alberta Stroke Program Early Computed Tomography Score on magnetic resonance images was 8. 7. We performed balloon guide catheter occlusion in three patients due to large thrombia. In two patients, sheath occlusion occurred in two cases, and thrombus migration into the femoral artery around the sheath was observed. When it's attempted in a single step, catheter and sheath occlusion may occur, raising the possibility of critical systemic artery occlusion.

Older age, internal carotid artery stenosis, and female sex as factors correlated with twisted carotid bifurcation based on 457 angiographic studies and a literature review

Carotid bifurcation in patients undergoing carotid endarterectomy is a well-known anatomical variation of the carotid bifurcation. paraphrased artery stenosis, although some studies into TCB have focused on patients with no internal carotid artery stenosis. This research was conducted to determine the characteristics of TCB in patients with ICA stenosis and other pathologies. TCB was discovered in 89 of 457 patients; among these 89 patients, 74 had TCB on the right side, 8 only on the left side, and 7 bilaterally. TCB was more prevalent among older patients, female patients, and patients with ICA stenosis or occlusion at the bifurcation site, according to the bifurcation. TCB was 19. 5% in the first year, and 84. 4% of cases were on the right side in patients with various pathologies. TCB is more likely among seniors, female patients, and patients with ICA stenosis or occlusion are more likely to have TCB.

Okanin from Coreopsis tinctoria Nutt. alleviates cognitive impairment in bilateral common carotid artery occlusion mice by regulating the miR-7/NLRP3 axis in microglia.

However, the role of okanin in cognitive impairment following ischemic stroke is still unclear. Both in vivo and in vitro, we investigated the effects of okanin on ischemic stroke and its underlying mechanism in this research. NLRP3-inflammatory activation in oxygen-glucose deprivation and lipopolysaccharide-stimulated microglia has been reduced by increasing miR-7 expression and limiting neuronal injury by increasing microglia-induced neuronal injury, according to Okanin. This research provides new insight into okanin's role in ischemic stroke and shows that the miR-7/NLRP3 axis plays a key role in mediating the beneficial effects of okanin on cerebral ischemia.

3D carotid artery segmentation using shape-constrained active contours.

First the centerline of the carotid artery is localized and then a modified active contour is used to extract the vessel lumen, and then the likelihood atlas generated by the deep learning network in the polar representation domain is embedded into the active contour as a precursor to determining the outer wall.

The Height and Mobility of Protruding Plaque After Carotid Artery Stenting Are Associated with Postoperative Ischemic Lesions.

Background Tissue protrusion is a possible cause of cerebral infarction after carotid artery stenting. After CAS, we investigated the correlation between the morphological characteristics of TP and postoperative new ischemic lesions on MRI-diffusion weighted imaging after CAS using optical frequency domain imaging and angioscopy. On MRI-DWI, we compared the past and post-stenting intravascular findings between patients with and without postoperative new ischemic lesions. The frequency of TP varied between the two groups, but the frequency of TP increased in the DWI-positive group was not different between the two groups, but mobile TP was only present in the DWI-positive group. The height of TP was an independent predictor of new periprocedural brain lesions after CAS, and it was reduced-off value was 0. 55 mm on the receiver operating characteristic curve. Conclusions of the MRI-DWI Investigator The emergence of TP on OFDI and mobile-TP angioscopy after CAS was associated with postoperative new ischemic lesions on angioscopy was shown.
