there is no single standard for conducting HAL-RAR operations. The constant discussion raises the question of the number of terminal branches of the superior rectal artery, which must be ligated in the submucosal layer of the rectum in order to provide the adequate dearterialization of hemorrhoids. <bold>Aim:</bold> To study the anatomy of the branches of the superior rectal artery and to develop recommendations for the optimal ligation of the terminal branches of the superior rectal artery. <bold>Methods:</bold> 150 protocols of the previous operations have been studied. In order to further objectify our results, the results of radiation diagnostics (CT and MRI) were revised for 100 patients without pathological changes of the rectum and anal canal to study the variant anatomy of the superior rectal artery and its terminal branches in the rectal wall. <bold>Results:</bold> In 148 patients, 6 terminal branches were identified, in 2 (1.333%) patients, 5 branches were found. 100 cases without pathological changes were also analyzed (60 MRI and 40 CT scans). In all the cases, 6 terminal branches of the superior rectal artery were determined, located at 1, 3, 5, 7, 9 and 11 o'clock positions of the conventional dial. At the same time, a large number of identified anatomical options for the branching of the VPA and the method for reaching the rectal wall should be noted, which we used as a basis to propose a classification. <bold>Conclusion:</bold> In the vast majority of cases, there are 6 terminal branches of the superior rectal artery, located in the lower ampulla of the rectum at approximately 1, 3, 5, 7, 9 and 11 hours of the conventional dial. A number of variants of the vascular anatomy of the proximal branches are possible, but 6 distal branches are involved in the direct blood supply of the hemorrhoids. When performing selective Doppler-controlled dearterialization of hemorrhoids, it is expedient to ligate 6 arterial vessels.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Обоснование.</bold> Единый стандарт проведения операций HAL-RAR отсутствует. Постоянные дискуссии вызывает вопрос о количестве терминальных ветвей верхней прямокишечной артерии, которые необходимо перевязать в подслизистом слое прямой кишки с целью осуществления адекватной дезартеризации геморроидальных узлов. <bold>Цель исследования</bold> — изучить анатомию ветвей верхней прямокишечной артерии и выработать рекомендации по оптимальному лигированию терминальных ветвей верхней прямокишечной артерии. <bold>Методы.</bold> Изучено 150 протоколов ранее выполненных операций. С целью дальнейшей объективизации наших результатов для исследования вариантной анатомии верхней прямокишечной артерии и её конечных ветвей в стенке прямой кишки были пересмотрены результаты компьютерных (КТ) и магнитно-резонансных (МРТ) томограмм 100 пациентов без патологических изменений прямой кишки и анального канала. <bold>Результаты.</bold> У 148 (98,7%) пациентов выявлено 6 терминальных ветвей, у 2 (1,3%) — 5 ветвей. Проанализированы также результаты лучевой диагностики 100 пациентов (60 МРТ и 40 КТ) без патологических изменений прямой кишки и анального канала. Во всех случаях определялось 6 терминальных ветвей верхней прямокишечной артерии, локализованных на 1, 3, 5, 7, 9 и 11 часах условного циферблата. При этом следует отметить большое количество выявленных анатомических вариантов ветвления верхней прямокишечной артерии и способа достижения стенки прямой кишки, на основании чего предложена классификация. <bold>Заключение.</bold> В подавляющем большинстве случаев имеется 6 терминальных ветвей верхней прямокишечной артерии, локализованных в нижнеампулярном отделе прямой кишки ориентировочно на 1, 3, 5, 7, 9 и 11 часах условного циферблата. Возможны различные варианты сосудистой анатомии проксимальных ветвей, но в непосредственном кровоснабжении геморроидальных узлов участвует 6 дистальных ветвей. В ходе выполнения селективной допплерконтролируемой дезартеризации геморроидальных узлов целесообразной является перевязка 6 артериальных сосудов.</p></trans-abstract><kwd-group xml:lang="en"><kwd>hemorrhoids</kwd><kwd>desarterization</kwd><kwd>lifting</kwd><kwd>ligation</kwd><kwd>HAL-RAR</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>геморрой</kwd><kwd>дезартеризация</kwd><kwd>лифтинг</kwd><kwd>лигирование</kwd><kwd>HAL-RAR</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Pucher PH, Sodergren MH, Lord AC, et al.
