PURPOSE We reviewed our initial thoracic aorta (TA) stent graft experience in 28 patients from the perspective of treatment with homemade devices (Dacron over Gianturco Z stents; 14 cases) and a commercial device (Excluder; W.L. Gore Co, Flagstaff, Ariz; 14 cases). METHODS From November 1996 to August 2001, 28 patients with a spectrum of disease(More)
The purpose of the study was to assess the clinical safety and efficacy of the "Recovery(TM)" (Bard) inferior vena cava (IVC) filter. We retrospectively evaluated the clinical and imaging data of patients who had a "Recovery(TM)" IVC filter placed between January 2003 and December 2004 in our institution. The clinical presentation, indications, and(More)
PURPOSE To review the indications, technical approach, and clinical outcomes of thoracic duct embolization (TDE) and thoracic duct disruption (TDD) in patients with symptomatic chylous effusions. MATERIALS AND METHODS A total of 105 patients who underwent 120 consecutive TDE/TDD procedures were retrospectively reviewed. Data including cause of effusion,(More)
Pelvic venous insufficiency (PVI), defined as retrograde flow in the gonadal and internal iliac veins, is the underlying cause of pelvic congestion syndrome (PCS), a common cause of disabling chronic pelvic pain in women of child-bearing age. PCS is a chronic pain syndrome characterized by positional pelvic pain that is worse in the upright position and is(More)
PURPOSE To evaluate the clinical effectiveness and safety of uterine artery embolization (UAE) in the treatment of primary postpartum hemorrhage (PPH), secondary PPH, and PPH associated with cesarean section. MATERIALS AND METHODS All women who underwent UAE for obstetric-related hemorrhage during a 52-month period culminating in April 2009 were included.(More)
The purpose of these guidelines is to recommend appropriate imaging for patients with blunt chest trauma. These patients are most often imaged in the emergency room, and thus emergency radiologists play a substantial role in prompt, accurate diagnoses that, in turn, can lead to life-saving interventions. The ACR Appropriateness Criteria® are evidence-based(More)
The thoracic duct is the body’s largest lymphatic conduit, draining upwards of 75 % of lymphatic fluid and extending from the cisterna chyli to the left jugulovenous angle. While a typical course has been described, it is estimated that it is present in only 40-60% of patients, often complicating already challenging interventional procedures. The lengthy(More)
This correspondence presents a new pixel-recursive algorithm for estimating the nonuniform image motion from noisy measurements. The proposed method is performed in two steps. First, the pixels are examined to identify the (detectable) moving pixels, using a binary hypothesis testing. Then, characterizing the motion of the identified moving pixels in terms(More)
PURPOSE To assess the level of vascular enhancement of gadolinium-enhanced aortoiliac computed tomographic (CT) angiography with a 16-detector row CT scanner and to compare it with the results of previous similar studies that used four-detector row CT units. MATERIALS AND METHODS Eleven gadolinium-enhanced CT angiograms were obtained in 10 consecutive(More)
