OBJECTIVES The aims of this study were to determine if angiographic findings can be used to predict successful nonoperative therapy of splenic injury and to determine if coil embolization of the proximal splenic artery provides effective hemostasis. METHODS Splenic injuries detected by diagnostic imaging between 1981 and 1993 at a level I trauma center(More)
Advances in interventional angiography such as covered stent technology and adjunctive anticoagulation and antiplatelet therapy for arterial recanalization have reached the margins of percutaneous application. In these circumstances, compression methods of arterial closure require prolonged compression or long arterial sheath dwell times that increase(More)
PURPOSE To evaluate the available data on stent-graft repair of acute blunt traumatic thoracic aortic injury with regard to safety and efficacy compared with conventional open surgical repair. MATERIALS AND METHODS The literature on endovascular repair of acute traumatic aortic injury since 1990 was systematically reviewed. Metaanalysis of publications(More)
PURPOSE To examine prospectively the effects of balloon inflation time on the technical success of balloon angioplasty in dialysis access venous stenosis and on postintervention primary patency. MATERIALS AND METHODS The study design was approved by the institution's Committee for the Protection of Human Subjects, and informed consent was obtained.(More)
Therapeutic embolization of the gonadal veins is performed on male and female patients for different clinical situations using similar techniques. The testicular varicocele is a common clinical problem associated with pain and reduced fertility rates. In women, chronic pelvic pain can be attributed to pelvic congestion syndrome, which is said to result from(More)
HYPOTHESIS Measurement of pelvic hemorrhage on computed tomographic (CT) scans can estimate the pelvic fracture component of total patient blood loss and predict the need for angiography. DESIGN Retrospective cohort study. SETTING Large level 1 trauma center. PATIENTS We examined data from 759 consecutive, nonreferral blunt trauma patients who(More)
BACKGROUND Pelvic fractures can be an important source of major hemorrhage in victims of blunt trauma. However, no rapid and reliable noninvasive method exists for predicting which subjects will have major hemorrhage. The objective of this study is to use information available upon presentation to the trauma center to develop a clinical prediction rule to(More)
BACKGROUND Endovascular stent grafts (EVSGs) offer an alternative in the management of traumatic rupture of the aorta, particularly in patients who are at prohibitive operative risk. METHODS We conducted a retrospective review of 11 cases managed by EVSGs over a 4-year period. EVSGs were defined as "noncommercial" (graft material hand sewn over metallic(More)
PURPOSE To report the endovascular treatment of a relatively uncommon type of deceleration injury to the abdominal aorta. CASE REPORT A 21-year-old backseat passenger was wearing a single lap belt without shoulder harness when the car was involved in a collision. He sustained a transverse (Chance) fracture of the third lumbar vertebra and a(More)
BACKGROUND Traumatic rupture of the thoracic aorta (TRA) in the pediatric population is uncommon. Management of TRA in general has evolved to include selective nonoperative and endovascular stent graft approaches, although operative repair remains the standard. METHODS We conducted a retrospective chart review of patients younger than 16 years of age(More)
