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).
