Background: The main objective of this study is to evaluate and compare the outcomes regarding operative mortality rate, ipsilateral stroke, and overall survival rate among patients with internal carotid artery stenosis submitted to carotid endarterectomy (CEA) or stenting regarding the completeness of circle of Willis (CoW).
Methods: Prospective, consecutive cohort study of patients submitted to carotid interventions (CEA and carotid stenting: CAS) for internal carotid artery stenosis diagnosis evaluated according complete or incomplete CoW. The patients were divided into 2 groups: group I, the patients with complete CoW and group II, the patients with incomplete CoW, with the disruption of anterior and/or ipsilateral posterior circulation, regarding the ipsilateral significant carotid stenosis.
Background: To determine the results, safety, and clinical outcomes of carotid interventions performed with duplex ultrasound (DUS) as a single preoperative image for internal carotid artery (ICA) assessment, compared to computed tomography angiography (CTA) and magnetic resonance angiography (MRA).
Methods: Prospective, consecutive cohort study of 2 groups of patients submitted to carotid interventions, 1 group of patients with DUS as a sole exam (group DUS) compared to patients with DUS plus CTA or MRA for ICA stenosis diagnosis (group CTA/MRA) regarding clinical outcomes such as major stroke, minor stroke, transient ischemic attack and perioperative mortality.
Results: Two groups of patients were identified: group DUS with 47 patients and group CTA/MRA plus DUS with 68 patients.
Article Synopsis
- A study evaluated the effectiveness of virtual reality simulator (VRS) training versus box-trainer (BT) training for minimally invasive surgery (MIS) techniques.
- A systematic review included 20 randomized clinical trials, with meta-analysis showing that VRS training reduced the time needed for a specific task and improved performance scores.
- Overall, while VRS training showed advantages in certain aspects, both training methods were similar in terms of time and performance on advanced tasks in MIS.
