RAPID Tmax map was useful for determining the site of acute right internal carotid artery occlusion presenting with cerebral infarction in the right posterior cerebral artery region

Background: A relative cerebral blood flow of 6 s is established as the penumbra in computed tomography perfusion using rapid processing of perfusion and diffusion, and the perfusion mismatch is estimated. We'll discuss here the case of a patient with right posterior cerebral artery occlusion based on RAPID study using CT perfusion. However, with fetal-type PCA. Case Research, a 94-year-old woman arrived in our hospital in unconscious state and was admitted for emergency medical assistance. Right PCA and correct ICA occlusion were found by magnetic resonance angiography, with blood flow to the right middle cerebral artery showing cross-flow through the anterior communicating artery. The right MCA had a Tmax of > 4 seconds on the Tmax chart, indicating a blood flow disturbance in the right MCA.

Intracranial Flow Volume Estimation in Patients with Internal Carotid Artery Occlusion

Patients with ICA occlusion: patients with significant volumetric flow compensation, patients with flow similar to the healthy population, and patients without compensation were found among patients without compensation. Patients with significant volumetric flow compensation tend to rise with age, as well as a simultaneous decline in the group without compensation. In both the ECA and VA, compensatory increased flow was found in approximately half of all patent extracranial arteries and was more prominent in ipsilateral vessels than in contralateral ones; however, in both the ECA and VA, the ICA played the most significant role in volumetric flow compensation in patients with CAO; however, the ICA increased flow was more apparent in ipsilateral vessels than in congestive ones; however, in both the ECA and VA. Conclusions: Volumetric flow compensation may have a significant predictive role in patients with CAO.

Hybrid surgery versus endovascular intervention for patients with chronic internal carotid artery occlusion: A single-center retrospective study

ObjectiveChronic internal carotid artery occlusion may cause transient ischemic attack and ischemic stroke. Effective methods for carotid revascularization are embolic protection devices and hybrid surgery carotid endarterectomy and endovascular therapy. 44 patients underwent hybrid surgery and 35 who underwent endovascular intervention at our center were enrolled consecutively between May 2016 and March 2022, according to this report. Results, From clinical studies, angiographic characteristics, perioperative complications, and follow-up data revealedThere were no significant differences between hybrid surgery group and EI group, except for plasma high density lipoproteins levels. The rate of hybrid surgery was much higher than that of EI. ConclusionsIn addition, there were no significant differences in the incidences of stroke and restenosis during follow-up studies. In addition, patients with symptomatic CICAO may have a leg up on EI in successfully restoring occluded segments.

High-resolution magnetic resonance imaging for predicting successful recanalization in patients with chronic internal carotid artery occlusion

paraphrasedoutput:Methods is a website that publishes articles about Patients with chronic internal carotid artery occlusion. The primary aim of the study was to determine the predictive factors of high-resolution magnetic resonance imaging for successful recanalization in patients with chronic internal carotid artery occlusion. According to the model coefficients, success rates for endovascular recanalization in patients with CICAO were between 93. 3 percent, 66. 67%, or 0%, respectively. ConclusionHR-MRI results can help identify candidates for endovascular recanalization in patients with CICAO patients.

A single-center retrospective study with 1-year follow-up after CEA in patients with severe carotid stenosis with contralateral carotid artery occlusion

paraphrasedoutput:MethodsThe aim of this study was to investigate the risk factors associated with adverse events following carotid endarterectomy in patients with unilateral severe carotid stenosis and contralateral occlusion. The carotid clamp time is defined as the time between clamp-on and clamp-off for the stenotic carotid artery. Patients with adverse outcomes had significantly longer CCT than those without adverse events. After accounting for confounding factors, such as age, sex, BMI, PSV, long CCT, non-use of shunt, and history of stroke or TIA, diabetes could have been correlated with diabetes-related adverse events; after CEA, chronic carotid stenosis and contralateral occlusion were statistically significant.
