Currently, we are witnessing changes in treatment tactics for patients with peptic ulcer bleedings (PUB) with endoscopic hemostasis at first place herewith the second place is now occupied by Transcatheter Arterial Embolization (TAE) for patients classified as "high risk". However, the TAE has limitations and can be analyzed depending on its technical and clinical effectiveness.

a retrospective single-center study from 2021 to 2024 enrolled 112 patients with acute ulcer gastroduodenal bleeding with indications for (TAE). The distribution of patients - (71.4%) men and 32 (28.6%) women. The average age 67.3±14.3 years. The patients divided into 2 groups: a group with technically efficient TAE (n1=97) and a second group (n2=15) – TAE was not technically efficient.

A comparison of both groups did not reveal significant differences in such control points as rebleeding, "open" surgery, mortality and blood transfusion. Significant differences revealed only in case of abnormal anatomy of target artery, which observed in 30 (30.9%) and 12 (80%) patients accordingly, also significant was the need for arterial access conversion in 6 (6.2%) and 6 (40%) patients in both groups.

Endoscopic hemostasis makes it possible to control most of PUB herewith TAE can be prescribed in patients of "high risk". Technical efficiency of TAE achieved in 86.6% patients, but even after it rebleeding observed in 19.6% of patients. Complications after TAE accounted for 26.8% of cases. The confirmed risk factors for predicting the inefficiency of TAE include ulcers>20 mm in size, abnormal arterial anatomy and the need for access artery conversion.
