Abstract

The objective of the study is to clarify the topographic and anatomical features of the most common perforating veins of the lower extremities.Material and methods. 70 lower extremities (sectional material) without signs of chronic venous diseases and 1700 patients. Research methods: anatomical dissection and ultrasound examination of the venous system of the lower extremities (duplex ultrasound scanning).Results. 4 to 6 perforants were found on the medial surface of the foot. They directly connected the medial boundary of the vein and vv. plantaris medialis. They are located along the medial intermuscular septum at the subfascial level; have subcutaneous tributaries from the medial surface of the foot at the epifascial level. The most constant localization of perforating veins on the ankle was the distal part of the medial surface of the ankle. On the ana to mic preparations they were the main draining vessels of this area. All perforating veins of the ankle (direct and indirect) and foot are the part of the neurovascular bundle, and at the subfascial level of the perforating veins 2, are located on the sides of the artery, next to the nerve branch. Rare incidence of perforating veins of the popliteal region, combining with the lack of typical saphenopopliteal anastomosis, allows relating them to the atypical PV. Among all of the perforating veins of the thigh, the highest frequency of incidence was in the lower third. These veins connected the great saphenous vein, and the femoral vein in 55.6 %. They passed along the medial intermuscular septum and had a long subfascial course. In all cases there is nearby arterial twig.Conclusion. Perforating veins in different areas of the lower extremities have their features of structure. General is that perforating veins mostly are the neurovascular bundles (vein – artery – nerve).

Abstract

Статья посвящена проблеме исследования видеозаписей неудовлетворительного качества в целях идентификации неизвестного лица и поиску направлений устранения данной проблемы. При решении поставленных задач было выявлено две тенденции. Первая из них указывает на необходимость разработки методических рекомендаций и внесения изменений в действующую методику судебной портретной экспертизы, которые регулировали бы вопросы, касающиеся оценки качества видеозаписи, установления факта монтажа и объективной оценки значимости выявленных групповых и индивидуальных анатомических признаков элементов внешнего облика. Вторая тенденция определяет важность исследования функциональных (динамических) признаков при идентификации лица по видеоизображениям неудовлетворительного качества. В ходе анализа криминалистической литературы и методик проведения судебных экспертиз выдвинуто обоснованное предложение о выделении данного криминалистического исследования в самостоятельную экспертизу для увеличения значимости выявленного комплекса признаков и результативности исследования в целом. В статье определено также место идентификации личности по функциональным признакам в системе судебных экспертиз., The article is devoted to the problem of studying videos of unsatisfactory quality in order to identify an unknown person, and finding directions for solving this problem. When solving the tasks, two trends were identified. The first trend indicates the need to develop methodological recommendations and make changes to the current methodology of forensic portrait examination, which would regulate issues related to assessing the quality of video recordings, establishing the fact of editing videos and objective assessment of the significance of identified group and individual anatomical features of the appearance elements. The second trend indicates the need to study functional (dynamic) features when identifying a person from video images of unsatisfactory quality. After analysis of the forensic literature and forensic techniques was put forward a substantiated proposal to distinguish this forensic study into an independent examination in order to increase the significance of the identified set of features and the effectiveness of the study as a whole. The article also determined the place of the forensic examination of personality identification by functional features in the system of forensic examinations., Судебная экспертиза, Выпуск 4 (60) 2020
