Endovascular therapy for acute trauma: a pictorial review.

The traditional role of radiology in the multidisciplinary approach to modern trauma care has been primarily diagnostic and noninvasive. With the advent of more sophisticated and faster imaging equipment, computed tomography has further entrenched its role as the workhorse of trauma imaging. However, the specialty has evolved over the years with various therapeutic techniques now part of the interventional radiology armamentarium. Several of these techniques have become essential for the management of critically ill trauma patients. This article provides an overview of the common imaging findings of vascular and solid organ trauma from head to toe and subsequent endovascular interventions in these critically ill trauma patients.

Novel use of the Surefire antireflux device in subtotal splenic embolization.

An unstable patient presented with an enlarging splenic hematoma, for whom splenectomy was contraindicated. The decision was made to treat this patient with subtotal splenic embolization. Initial attempts at embolotherapy using a conventional end-hole catheter resulted in a false angiographic end point with reflux into short gastric arteries, likely due to splenic parenchymal pressurization from the hematoma. The Surefire antireflux device (Surefire Medical Inc, Westminster, Colo) was therefore employed. The Surefire device allowed successful subtotal splenic embolization. Whereas it is currently primarily used in hepatic interventional oncology, we have shown that it can be successfully used in other settings to increase embolization efficiency while mitigating nontargeted embolization.
