Abstract
The results of research of anatomy of rectal arteries by an angiography method are presented. AIM. To study “in vivo” specific features of anatomy of rectal arteries in rectum blood supply and to justify the usefulness of endovascular interventions in patients with rectal cancer. MATERIALS AND METHODS. The analysis angiograms of 123 patients of various age and sex is carried out. RESULTS. The superior rectal artery is the main source of rectum blood supply. Middle rectal arteries are an additional source. In vivo bilateral asymmetry with primary development of the left vessel is observed.. The inferior rectal arteries are visualized less than in one third part of cases. Rectal artery have a extensive network of anastomoses with other pelvis vessels. CONCLUSIONS. The results justify the anatomical possibility and feasibility of endovascular methods in rectal cancer therapy considering individual features of rectum blood supply.

Summary
Изучение прижизненной ангиоархитектоники прямокишечных артерий и индивидуальных особенностей кровоснабжения прямой кишки проводили на основании ретроспективного анализа данных аортографий и ангиографий 108 пациентов с атеросклеротическим поражением подвздошно-бедренного сегмента и артерий нижних конечностей. Также в исследование включили 15 пациентов, в возрасте от 43 до 69 лет (средний возраст 57,3±2,1 лет), с морфологически подтвержденным диагнозом аденокарциномы прямой кишки, прорастающей все слои кишечной стенки. В зависимости от селективности вмешательства использовали различные катетеры (MP, Cobra, JR, Roberts) диаметром от 3,5F до 5F, микрокатетеры PROGREAT® (Terumo), а также прямые и J-образные проводники 0,035” (Cook, Cordis, Terumo). Статистический анализ производили с использованием пакета анализа Statistica 6.1 (StatSoft, Inc.)
