Video_1_The human placenta as a model for training and research in mechanical thrombectomy: Clarifications and use of the chorionic plate veins.AVI
Indications for mechanical thrombectomy in acute ischemic stroke are increasing, resulting in the continuous development of new devices and techniques. Therefore, there is a need for a realistic testing and training environment that offers the opportunity to practice different procedures and test the latest devices. Some authors have described the use of the human placenta as a model for neurointerventional surgery, with striking similarities to real-life conditions. This model has many advantages, including its relatively low cost and minimal infrastructure requirements, with fewer ethical concerns compared to animal models. So far, some preparation and set-up details were missing, and only arteries from the chorionic plate were used. This article provides the necessary clarifications and a mapping of the chorionic plate veins, so that the use of this model, which is particularly well suited for mechanical thrombectomy, can be as easy and wide as possible. A video explaining how to prepare the model is provided.</p
DGML semi-quantitative scale.
<p><b>A</b>. No lesion; <b>B</b>. Punctuate lesion; <b>C</b>. Lesion involving less than 1/3<sup>rd</sup> of the nucleus. <b>D</b>. Lesion involving between 1/3<sup>rd</sup> and 2/3<sup>rd</sup> of the nucleus. <b>E</b>. Lesion of more than 2/3<sup>rd</sup> of the nucleus. <b>F</b>. Total involvement of the nucleus.</p
Cross validation (Jacknife test).
<p>In each validation test, we used data from all but one subject (S -1 of the S subjects) to train the classifier.</p

Receiver operating characteristic (ROC) curves and area under the curve (AUCs) for the different grading scales used in this studies, alone or in combination, with or without the factor “age” taken into account.
<p>Note that the AUC of the ROC curve of the DGM nuclei grading scale was higher than the one of the other scores, alone or combined, with or without the age.</p
