38 Embolizaton of Pelvic Hemmorhage after Blunt Trauma


Clinical Presentation

A 14-year-old male presented to the emergency room of an outside hospital after being ejected from an automobile after an accident. He was stabilized with blood products and fluids and underwent plain film and subsequent CT examinations.

Radiologic Studies

Plain Film of Pelvis

Frontal view of the pelvis (Fig. 38-1) obtained on a backboard showed diastasis of the symphysis pubis and a comminuted fracture of the proximal left femur.

Contrast-Enhanced CT

Views through the pelvis (Fig. 38-2A) showed diastasis of the left sacroiliac joint, an expanding pelvic hematoma, and active bleeding at the base of the penis (Fig. 38-2B). The patient was transferred for urgent pelvic angiography.

Angiography with Embolization

The right common femoral artery was punctured using the Seldinger technique, and a 5-French (F) sheath was inserted. A pigtail catheter was advanced into the abdominal aorta and pelvic arteriography was performed (Figs. 38-3A, B) revealing a pseudoaneurysm near the junction of the anterior and posterior divisions of the left internal iliac artery was catheterized. The posterior division was not visualized and was presumed to be in spasm or transected. The left internal iliac artery was catheterized using the pigtail catheter. A 3F microcatheter (Tracker 325, Boston Scientific, Natick, Massachusetts) was then advanced across the pseudoaneurysm and used to deploy a combination of Gelfoam slurry (Pharmacia and Upjohn, Kalamazoo, Michigan) and metal microcoils (Fig. 38-4). A postembolization pelvic angiogram showed complete occlusion at the site of embolization (Fig. 38-5).
