ABSTRACT
Pelvic fractures are common in cases of blunt trauma, which is strongly associated with mortality. Transcatheter arterial embolization is a fundamental treatment strategy for fatal arterial injuries caused by blunt pelvic trauma. However, vascular injuries due to blunt pelvic trauma can show various imaging findings other than arterial hemorrhage. We present a pictorial review of common and uncommon vascular injuries, including active arterial bleeding, pseudoaneurysm, arteriovenous fistula, arterial occlusion, vasospasm, and active venous bleeding. Knowledge of these vascular injuries can help clinicians select the appropriate therapeutic strategy and thus save lives.

Percutaneous transhepatic stent-graft placement usually requires more than a 12 F sheath, which has a higher potential risk of peritoneal hemorrhage. A case of postoperative portal vein hemorrhage after pancreaticoduodenectomy treated using a Viabahn VBX balloon expanding stent-graft is described in this report. The stent-graft was delivered using an 8 F sheath through a transhepatic approach and deployed from the superior mesenteric vein to the main portal vein. Hemostasis was achieved and graft patency was confirmed one year after the procedure.
