    The results of evaluation of the soft tissue perfusion of the foot in patients with diabetes and critical lower limb ischemia (CLI) via fluorescence angiography (FAG) in the near-infrared range are represented in the article. The study included 4 diabetic patients with CLI. All patients underwent lower-limb balloon percutaneous transluminal angioplasty. To evaluate the soft tissue perfusion of the foot via FAG the following parameters have been used: T0m - time to reach maximum for fluorescence intensity after intravenous administration of Indocyanine green; TIm- time of onset of maximum fluorescence intensity after its appearance in the area of interest; Im - the level of the maximum fluorescence intensity. The region of interest was the skin around the wound of the foot. The median FAG parameters in the region of interest on the foot were as follows: prior to surgery T0m = 164 sec (148–181), TIm = 48 sec (38–56); after surgery: T0m = 80 sec (69–92); TIm = 27 sec (20–39); (p <0,05). No adverse reactions were registered in the study. Despite the small sample we were able to achieve statistical significance in the difference between the parameters prior to and after surgery. Further prospective studies with extended samples of patients are needed.В работе представлены результаты оценки перфузии мягких тканей стопы у пациентов с сахарным диабетом и критической ишемией нижних конечностей с помощью метода флуоресцентной ангиографии (ФАГ) в ближнем инфракрасном диапазоне. В исследование были включены 4 пациента с сахарным диабетом и критической ишемией нижних конечностей. Всем пациентам была выполнена чрескожная транслюминальная баллонная ангиопластика артерий нижних конечностей. Для оценки перфузии тканей стопы при помощи метода флуоресцентной ангиографии были определены следующие параметры: T0m – время достижения максимальной интенсивности флуоресценции с момента внутривенного введения индоцианина зеленого; TIm – время наступления максимальной интенсивности флуоресценции с момента ее появления в зоне интереса; Im – уровень максимальной интенсивности флуоресценции. Зоной интереса являлась кожа в околораневой зоне стопы. В результате были получены медианы параметров ФАГ в исследуемой области стопы: до операции – T0m = 164 с (от 148 до 181), TIm = 48 с (от 38 до 56), и после операции – T0m = 80 с (от 69 до 92), TIm = 27 с (от 20 до 39) (р<0,05). В ходе исследования неблагоприятных реакций зафиксировано не было. Несмотря на небольшую выборку, удалось получить статистически значимую разницу указанных параметров у пациентов до и после операции. Необходимо проведение дальнейших проспективных исследований с расширением выборки пациентов
