Purpose: The purpose of this study is to evaluate the relationship between the patterns of pelvic bone fracture and location of hemorrhage on angiography.
Materials and Methods: We retrospectively reviewed 56 patients with pelvic bone fracture and active bleeding. Fractures were classified according to Tile classification. Locations of bleedings were divided into four groups; main trunk/anterior/posterior divisions of internal iliac artery, and other locations. The relationship between the fracture pattern and bleedings were analyzed statistically.
Results: Forty-one bleedings were in 22 patients with type A fracture. Twenty (49%) were at the anterior division, 12 (29%) were at the posterior division, and 9 (22%) were found in other location. Thirty-three bleedings were in 23 patients with type B fracture. Fifteen (45%) were at the posterior division, 10 (30%) were at the anterior division, 3 (9%) were at the main trunk of the internal iliac artery, and 5 (16%) were at other location. Eighteen bleedings were in 11 patients with type C fracture. Thirteen (72%) were at the posterior division, 4 (22%) were at the anterior division, and 1 (6%) was at main trunk of internal iliac artery. Anterior divisional bleedings were more common in type A, posterior divisional bleedings were more common in type B and C fractures (p = 0.014).
Conclusion: The distribution of bleeding is significantly related to the fracture patterns. Fracture pattern may help in predicting the location of bleeding foci on embolization.
