Table 5 Comparison of patients who underwent arterial embolization with and without evidence of contrast extravasation during computed tomography

From: High incidence of surgical site infection may be related to suboptimal case selection for non-selective arterial embolization during resuscitation of patients with pelvic fractures: a retrospective study
