Aims: To evaluate the outcome after early angiographic embolization in pelvic ring injuries associated with massive bleeding. Methods: We evaluated prospectively 32 consecutive patients. Special attention was paid to the þndings in angiography, the reliability of embolization, and the þnal result (survive or death). The causes of deaths were evaluated as well as the parameters correlating to this. Results: Angiography showed an isolated arterial injury in 16 (50%) and multiple arterial injuries also in 16 patients (50%). 9 patients had bilateral bleeding. Internal iliac artery and/or its main branches was the source of bleeding in 27 (85%), external iliac artery or its main branches in 2 (6%), and branches of both internal and external iliac arteries in 3 patients (9%).

The embolization was successful in all cases. 11 patients (34%) died. The early deaths (< 24h) were the result of massive bleeding in 4 out of 5 patients. One died to cardiac failure. Six late deaths were the result of MODS. All the died patients had more than one bleeding artery, and 6 had bilateral bleeding. The non-survivors had more severe injuries (mean ISS 51) and were older (mean age 50,2 yrs) than the survivors (mean ISS 41; mean age 43,9 yrs). Conclusions: Angiographic embolization is an effective and life saving procedure. It should be considered in hypotensive patients with unstable pelvic ring injuries who remain haemodynamically unstable following adequate resuscitation with component therapy and external þxation.
