Abstract Aim: was to determine the role of radiation and interventional methods of diagnosis and treatment of traumatic pelvic bleeding. Material and methods: for the period 2016 -2019, we analyzed results of diagnosis and treatment of 37 patients with pelvic injuries, complicated by intra-pelvic bleeding. CT scanning of retroperitoneal pelvic hematoma (RPH) was performed in all cases, results of calculations were compared with the surgical classification of I.Z. Kozlova (1988) on the spread of retroperitoneal hemorrhage and volume of blood loss in pelvic fractures. MSCT-A was performed in 16 (45%) injured. Digital subtraction angiography (DSA) was performed in 10 (27%) cases, of which after MSCT-A – in 4 cases, and as the primary method for the diagnosis of arterial bleeding – in 6 cases. Results: according to MSCT, the frequency of minor hemorrhages was 18 (50%), medium 16 (43%), large 3 (8%). CT calculation of the volume of small hemorrhages ranged from 92 to 541 cm3, medium – 477-1147 cm3, large –1534 cm3 and more. MSCT-A revealed signs of damage of arteries of the pelvic cavity: extravasation of contrast medium – in 4, cliff and «stop-contrast» – in 1, post-traumatic false aneurysm – in 1, displacement and compression of the vascular bundle – in 4 observations. DSA revealed signs of damage of vessels of the pelvis: extravasation of contrast medium – 3, angiospasm – 2 and occlusion – 2 observations. According to results of angiography, embolization of damaged arteries was performed in 5 observations. Conclusion: MSCT is a highly sensitive method in assessing the distribution and calculation of RPH volume. The presence of a hematoma volume of more than 50-100 cm3, regardless of the type of pelvic damage, was an indication for MSCT. In patients with stable hemodynamics, DSA was used as a clarifying diagnostic method; in patients with unstable hemodynamics, it was used as the main method for diagnosis and treatment of injuries of pelvic vessels. Damage of pelvic vessels detected by angiography was observed predominantly in unstable pelvic fractures, accompanied by medium and large retroperitoneal pelvic hemorrhages. References 1.
