Echolucent carotid plaque is associated with restenosis after carotid endarterectomy

After CEA, our study sought to explore the correlation between the carotid plaque grayscale median value and restenosis. METHODS Between January 2010 and January 2018, 1280 consecutive patients underwent CEA at our hospital; 32 patients were diagnosed with restenosis by ultrasound at 1 year after CEA. CONCLUSIONS PREdominantly echolucent carotid plaques, as determined by GSM, had a higher risk of restenosis at 1 year than echogenic plaques at 1 year.

Management of postoperative internal carotid artery intimal flap after carotid endarterectomy: a cohort study and systematic review

OBJECTIVE BETTERLE artery intimal flap after carotid endarterectomy for carotid artery stenosis is a potential complication. Some writers favor carotid stent placement or reoperation, while others prefer patient waiting. The aim of this research was to investigate the incidence and management of postoperative ICA-IF's postoperative ICA-IF, and moreover, to bring these findings into context with a systematic literature review. METHODS The authors reviewed all prospective CEA cases at the University Hospital of Bern over the past decade. ICA-IF was detected by routine duplex neurovascular ultrasound in 13 patients, corresponding to a prevalence rate of 1. 8%. There were no inflammatory thrombi on the detected IF. In 5. 6 percent of the 725 cases, Intraoperative shunt placement was used in 5. 6%, with one or two intima tack sutures being performed in 42. 5%. There was no significant correlation between intraoperative shunt placement and the occurrence of an IF. A transient postoperative neurological deficit was present in two patients with IF. The antiplatelet therapy was changed from a mono- to a dual-antiaggregating regimen in one patient with IF because of the IF resulted in a stenosis greater than 70%; this patient remained symptomatic. After a mean period of 6. 9 months, All 13 IFs vanished spontaneously. A postoperative ICA-IF incidence of 3. 8 percent was discovered by a systematic literature review, revealing a postoperative ICA-IF prevalence of 3. 8 percent with relatively heterogenous management practices. CONCLUSIONS Postoperative ICA-IF is a new find after CEA. Without associated intraluminal thrombi, Conservative therapy with close NVUS follow-up reports appears to be an effective and safe management strategy for asymptomatic IFs without associated intraluminal thrombi.

Development of cerebral microbleeds in patients with cerebral hyperperfusion following carotid endarterectomy and its relation to postoperative cognitive decline

However, the mechanisms that mediates cerebral hyperperfusion causes cerebral cortex and white matter injury are uncertain. This prospective observational research was designed to determine whether cerebral hyperperfusion following CEA leads to CMB formation and CMB formation, and whether postoperative cognitive decline is related to these newly developed CMBs. METHODS During the 27-month study period, patients who underwent CEA for ipsilateral internal carotid artery stenosis underwent SWI and neuropsychological examination before and after surgery, as well as quantitative brain perfusion SPECT prior to and immediately after surgery. FIGURE MULTITI A FIDE HETER I METHICAL TO ARTIFIC According to the results, 12 and 7 of 75 patients developed postoperative cerebral hyperperfusion and elevated CMBs in the cerebral hemisphere ipsilateral to surgery, respectively, according to quantitative brain perfusion SPECT and SWI. The risk of postoperative cognitive decline in patients with cerebral hyperperfusion after surgery was higher in those with elevated CMBs than in those without.

Endarterectomy for symptomatic internal carotid artery web

OBJECTIVE THE carotid web is a little-known source of cryptogenic, embolic stroke in patients younger than 55 years of age, with up to 37% of these patients having CW on angiography. paraphrased artery web's symptomatic internal carotid artery web. The authors describe their hospital surgical experience with patients treated via carotid endarterectomy for a symptomatic internal carotid artery web. After being diagnosed with ischemic stroke from January 2019 to February 2020, all patients who were screened underwent either carotid artery stenting or CEA. Twenty-five patients were treated by CEA, and out of these, six patients were diagnosed with ischemic strokes ipsilateral to CWs, including 3 patients who were suffering with recurrent strokes. In all patients, CT angiography or digital subtraction angiography demonstrated the presence of CWs ipsilateral to the stroke. One patient experienced mild tongue deviation most likely related to retraction, and the complete recovery at follow-up was evident.

Usefulness of Radial Artery as a Carotid Artery Patch in Simultaneous Carotid Endarterectomy and Coronary Artery Bypass Graft Operation with Complete Arterial Revascularization

The radial artery can be used safely as a patch material for carotid endarterectomy in combined surgery by using the full arterial revascularization method for coronary artery bypass graft procedure. Methods: The research included 14 patients with significant coronary artery disease with the stenosis of unilateral carotid artery equal/over 70% between 2016 and 2018. In conclusion, the radial artery is used for carotid patch angioplasty in patients who underwent simultaneous carotid endarterectomy and coronary artery bypass graft procedures with complete arterial revascularization.

Evaluation of Neurocognitive Abilities in Patients Undergoing Carotid Endarterectomy Surgery

The aim is to investigate the differences in neurocognitive performance between the preoperative and postoperative periods following carotid endarterectomy, owing to carotid artery stenosis, and to determine CEA's neurocognitive abilities in the future. Methods and methods: Thirty-eight cases of CEA surgery at Bozok University Faculty of Medicine Research Hospital between January 2015 and June 2020 were investigated. Neurocognitive tests were performed on carotid endarterectomy patients one day before the surgery and the second, 4th, and 30th postoperative days were observed on the 2nd, 4th, and 30th. The effect of CEA on cognitive outcomes has been investigated. In 20 cases, right carotid endarterectomy was performed, and left carotid endarterectomy was performed in 18 cases. The postoperative period decreased on the 2nd day, and then on the 4th and 30th day after the surgery, there was a small amount of increase over time. The learning score was found to be the lowest on the 2nd day, lower on the 4th day, compared to the preoperative period, and improved during the preoperative period on the 30th day. Test score results gradually decreased in the early postoperative period in comparison to the preoperative period and the increased on the 30th day compared to the preoperative period. CEA's neurocognition factors are multifactorial. Individualization of the therapy will help maximize cognitive development by prioritizing cognitive skills in the treatment of carotid stenosis by prioritizing cognitive skills, thus ensuring the patient receives the highest benefit of each factor.

Perioperative stroke during carotid endarterectomy: benefits of multimodal neuromonitoring - a case report

Abstract Background: Carotid endarterectomy is commonly performed after an ischemic stroke due to carotid stenosis. Case study The case of an 85-year-old male with perioperative haemodynamic stroke during carotid endarterectomy is presented here. Ischemic stroke was triggered by significantly elevated carotid stenosis, resulting in major neurologic deficit. Conclusion We strongly recommend the use of multimodal neuromonitoring, as well as transcranial doppler whenever possible to minimize the likelihood of persistent neurologic deficit following carotid endarterectomy.

Limitations of median nerve somatosensory evoked potential monitoring during carotid endarterectomy

In this research, the authors sought to investigate the shortcomings of MNSSEP monitoring relative to tibial nerve somatosensory, which inspired future monitoring for the detection of CC-related hypoperfusion. During CC, TNSSEP reported a greater number of SSEP changes than MNSSEP. Hypoplasia of the anterior cerebral artery and hypoplasia of the ipsilateral precommunicating segment of the posterior cerebral artery were inversely and positively correlated with stump pressure, according to linear regression results. Both contralateral A 1 hypoplasia and ipsilateral P 1 hypoplasia were attributed to TNSSEP changes. CONCLUSIONS TNSSEP monitoring appears to be more effective than MNSSEP in detecting CC-related hypoperfusion. Correspondence with stump pressure and SSEP changes indicates that TNSSEP, not MNSEP monitoring, is a reliable indicator of cerebral ischemia in the territory of the anterior cerebral artery.

Surgeon specialty and patient outcomes in carotid endarterectomy

METHODS The authors analyzed 80,475 patients who underwent carotid endarterectomy between 2006 and 2015 in the National Surgical Quality Improvement Program, a prospectively collected, national clinical registry with established reproducibility and reliability. The authors matched 203 neurosurgery patients and 203 general surgery patients to 203 general surgery patients using propensity scores, which include pre- and intraoperative characteristics as well as surgical and diagnostic codes. Patients undergoing carotid endarterectomy by a neurosurgeon tend to have a higher prevalence of preoperative disease than those treated by a general or vascular surgeon, which leads to more morbid postoperative courses. Patients were not chosen systematically on the basis of physical health status at the time of surgery and intraoperative variables that influence results, but patients' results after carotid endarterectomy do not appear to be dependent on the attending surgeon's primary specialty.

Outcome of carotid endarterectomy and stent insertion based on grading of carotid endarterectomy risk: a 7-year prospective study

The CEA and CASP groups were very similar in terms of the graded risk factors, but not randomized, except for a greater number of neurologically impaired patients in the CEA group. According to 2. 8 percent and 37. 9%, respectively, after CEA, the overall incidences of neurological morbidity with ischemic origin and the appearance of lesions on DW MR imaging after CEA were 2. 2 and 9. 3%, with 2. 3 and 9. 3%, respectively. There was no significant correlation between neurological morbidity and the risk grade in patients who had undergone CEA, but the incidence of lesions on DW imaging was markedly higher in the Grade IV risk group relative to that in other risk groups combined. Whether you're symptomatic or an asymptomatic presentation, a greater incidence of neurological morbidity and lesions on DW imaging was noted for the Grade II and III risk groups combined as compared to that in the Grade I risk group. After CEA, the incidence of lesions on DW imaging after CEA was significantly less than that before CASP, except for the Grade IV risk groups. Conclusions Despite a rise in the incidence of DW imagingu2013demonstrated lesions in the Grade IV risk group, there was no significant correlation between the risk group and clinical morbidity rates following CEA. Given that no significant nonneurological difficulties were reported, CEA and CASP appear to be complementary strategies of revascularization for carotid artery stenosis with various risk profiles.
