Iliofemoral venous thrombosis carries a high risk for pulmonary embolism, recurrent deep vein thrombosis, and post-thrombotic syndrome complicating 30% to 71% of those affected. The clinical scenarios in which iliofemoral venous thrombosis is managed may be diverse, presenting a challenge to identify optimum therapy tailored to each situation. Goals for management include preventing morbidity from venous occlusive disease, and morbidity and mortality from pulmonary embolism.

Venous thromboembolism (VTE)-deep vein thrombosis and pulmonary embolism-is a common cause of morbidity and mortality. The mainstay of VTE prophylaxis and therapy is anticoagulation. In select patients with VTE, inferior vena cava (IVC) filters are used to prevent pulmonary embolism by trapping emboli as they pass from the lower extremity venous system through the IVC.

Abdominal aortic aneurysms (AAAs) are a relatively common vascular problem that can be treated with either open, surgical repair or endovascular aortic aneurysm repair (EVAR). Both approaches to AAA repair require dedicated preoperative imaging to minimize adverse outcomes. After EVAR, cross-sectional imaging has an integral role in confirming the successful treatment of the AAA and early detection of complications related to EVAR.

Depending on the clinical presentation, the diagnosis is usually confirmed through Doppler vascular ultrasound, CT angiography, or MR angiography; the choice of imaging is usually based on modality availability and the presence of patient comorbidities such as chronic kidney disease. The Trans-Atlantic Inter-Society Consensus II classification system is commonly used to describe the extent of the peripheral vascular disease.

Obtaining central venous access is one of the most commonly performed procedures in hospital settings. Multiple devices such as peripherally inserted central venous catheters, tunneled central venous catheters (eg, Hohn catheter, Hickman catheter, C. R.

Materials And Methods: The study was HIPAA compliant and was approved by the institutional review board. Written informed consent was obtained from each patient.
Purpose: To retrospectively determine if controlled apnea improves the image quality of contrast material--enhanced magnetic resonance (MR) angiography of the chest and abdomen in children.
Materials And Methods: Institutional review board approval and waiver of informed consent were obtained for this HIPAA-compliant study. The authors evaluated contrast-enhanced MR angiographic procedures performed in the chest, abdomen, or both, in 23 children (14 boys, nine girls; age range, 1 month to 8 years) who were under general anesthesia.
Purpose: Identify features on preoperative computed tomography (CT) scans to predict suboptimal primary cytoreduction in patients treated for advanced ovarian cancer in institution A. Reciprocally cross validate the predictors identified with those from two previously published cohorts from institutions B and C.
Patients And Methods: Preoperative CT scans from patients with stage III/IV epithelial ovarian cancer who underwent primary cytoreduction in institution A between 1999 and 2005 were retrospectively reviewed by radiologists blinded to surgical outcome.
The institutional review board approved this HIPAA-compliant study and waived informed consent. The purpose was to retrospectively evaluate remote control magnetic resonance (MR) imaging in complex cardiovascular procedures, whereby operational expertise was made available locally from a remote location. Thirty patients underwent cardiac (12 patients) and/or vascular (30 patients) 1.

Transcatheter arterial embolization has become a major treatment modality in a variety of clinical applications, including management of bleeding related to a broad spectrum of obstetric and gynecologic disorders. Embolotherapy has a well-documented role in the management of pelvic and genital tract hemorrhage in the postpartum and postoperative/postcesarean setting. It is also an integral part in the treatment armamentarium of abdominal and cervical ectopic pregnancy, arteriovenous malformation, and gynecologic neoplasms, including more recently, uterine leiomyomata.

Materials And Methods: All examinations were HIPAA compliant.
