Delayed hemorrhage caused by coil migration after transcatheter arterial embolization in patient with unstable pelvic fracture: a case report.

摘要

Patients sustaining a pelvic fracture are at high risk for exsanguinations that may prove fatal. Uncontrolled pelvic hemorrhage from pelvic trauma leads to a mortality of 5% to 24% in multiply injured patients.1 In most patients, aggressive fluid resuscitation and blood component transfusion, with pelvic external fixation are adequate to establish hemostasis. Nevertheless, between 3.3% to 15% of patients2'3 may suffer from continuous bleeding. Transcatheter arterial embolization (TAE) has been advocated as a treatment of choice in this situation. In experienced hands, the success rate of TAE is between 85% and 100%. However, some of these patients may die later in their clinical course as a result of other causes. Here, we report on a patient who had successful TAE initially but suffered from delayed bleeding caused by migration of embolizing coils.
