- Abstract
Objective: Assess the use of a volumetric simulation tool for the evaluation of radiology resident MR and CT interpretation skills., Material and Methods: Forty-three participants were evaluated with a software allowing the visualisation of multiple volumetric image series. There were 7 medical students, 28 residents and 8 senior radiologists among the participants. Residents were divided into two sub-groups (novice and advanced). The test was composed of 15 exercises on general radiology and lasted 45 min. Participants answered a questionnaire on their experience with the test using a 5-point Likert scale. This study was approved by the dean of the medical school and did not require ethics committee approval., Results: The reliability of the test was good with a Cronbach alpha value of 0.9. Test scores were significantly different in all sub-groups studies (p < 0.0225). The relation between test scores and the year of residency was logarithmic (R
2 = 0.974). Participants agreed that the test reflected their radiological practice (3.9 ± 0.9 on a 5-point scale) and was better than the conventional evaluation methods (4.6 ± 0.5 on a 5-point scale)., Conclusion: This software provides a high quality evaluation tool for the assessment of the interpretation skills in radiology residents., Key Points: • This tool allows volumetric image analysis of MR and CT studies. • A high reliability test could be created with this tool. • Test scores were strongly associated with the examinee expertise level. • Examinees positively evaluated the authenticity and usability of this tool.- Published

Background and Purpose: The efficacy of endovascular therapy in patients with acute ischemic stroke due to tandem occlusion is comparable to that for isolated intracranial occlusion in the anterior circulation. However, the optimal management of acute cervical internal carotid artery lesions is unknown, especially in the setting of carotid dissection, but emergency carotid artery stenting (CAS) is frequently considered. We investigated the safety and efficacy of emergency CAS for carotid dissection in patients with acute stroke with tandem occlusion in current clinical practice. Methods: We retrospectively analyzed a prospectively maintained database composed of 2 merged multicenter international observational real-world registries (Endovascular Treatment in Ischemic Stroke and Thrombectomy in Tandem Lesion). Data from endovascular therapy performed in the treatment of tandem occlusions related to acute cervical carotid dissection between January 2012 and January 2019 at 24 comprehensive stroke centers were analyzed. Results: The study assessed 136 patients with tandem occlusion due to dissection, including 65 (47.8%) treated with emergency CAS and 71 (52.2%) without. The overall rates of favorable outcome (90-day modified Rankin Scale score, 0–2) and successful reperfusion (modified Thrombolysis in Cerebral Infarction, 2b–3) were 58.0% (n=76 [95% CI, 49.6%–66.5%]) and 77.9% (n=106 [95% CI, 71.0%–85.0%]), respectively. In subgroup analyses, the rate of successful reperfusion (89.2% versus 67.6%; adjusted odds ratio, 2.24 [95% CI, 1.33–3.77]) was higher after CAS, whereas the 90-day favorable outcome (54.3% versus 61.4%; adjusted odds ratio, 0.84 [95% CI, 0.58–1.22]), symptomatic intracerebral hemorrhage (sICH; 10.8% versus 5.6%; adjusted odds ratio, 1.59 [95% CI, 0.79–3.17]), and 90-day mortality (8.0% versus 5.8%; adjusted odds ratio, 1.00 [95% CI, 0.48–2.09]) did not differ. In sensitivity analyses of patients with successful intracranial reperfusion, CAS was not associated with an improved clinical outcome. Conclusions: Emergency stenting of the dissected cervical carotid artery during endovascular therapy for tandem occlusions seems safe, whatever the quality of the intracranial reperfusion.

Place: Germany; PURPOSE: The gastro-omental artery (GOA) with the greater omentum (GO) is known for its high quality as a vascular graft, its resistance to infections as an omental flap and for its multiple applications in surgery. A better knowledge of anatomical variations of GO and its vascularization can improve the application in surgery and decrease complications. The purpose of this study was to measure diameters and lengths of the right GOA (RGOA) and study the interindividual variability of these anatomical structures. METHODS: In 100 cadaveric dissections, we carried out dissection of the RGOA and of the GO. In 70 unfixed cadavers, the transillumination technique was used to identify all RGOA branches. In the remaining 30 cadavers, prepared with Winckler's solution, barium sulfate with colored latex was injected. Digital X-ray was used to measure RGOA lengths, internal diameters and the distribution of the omental branches. The gastro-omental vein was also dissected. RESULTS: The mean proximal and distal diameters of RGOA were 2.68 (± 0.39) mm and 0.94 (± 0.24) mm, respectively. The mean length was 244.3 (± 34.4) mm. The thickness of the omentum ranged from 5 to 15.5 mm. The arteria omentalis magna, defined in this study for the fist time as the longest and widest omental branch, was present in 73.3% cases. The trans-omental arch was present in 6% cases. CONCLUSIONS: This morphometric study allowed us to define the vascularization and the anatomical variations of RGOA and GO. This may lead to improvement of applications in surgery and decrease complications.
