Percutaneous Transjejunal Biliary Access in 60 Patients with Bilioenteric Anastomoses.

Purpose: To determine success and complication rates of percutaneous transjejunal biliary access (PTJBA) in patients with bilioenteric anastomoses.

Materials And Methods: In a single-center, retrospective study, 169 PTJBA procedures were performed over a 13.8-y period in 60 subjects (47 male; mean age, 54.

Descending tumor thrombus from renal cell carcinoma metastases with SVC syndrome.

We describe a case of renal cell carcinoma metastases to the thyroid gland invading local veins and extending to the neck veins causing superior vena cava (SVC) syndrome.

Percutaneous treatment of high-output chylothorax with embolization or needle disruption technique.

Surgical ligation of the thoracic duct is associated with a high degree of morbidity; therefore, a minimally invasive approach is desirable. Herein, eight percutaneously treated patients are described. In four patients, the thoracic duct was embolized with use of coils and glue.

Development and testing of a cross-sectional area measurement tool for evaluating vein size.

This paper describes a software system for measuring cross-sectional area in reconstructed elliptical tubular structures. A measurement tool was developed using the freely available, cross-platform, open-source three-dimensional (3-D) Slicer environment. The software is easy to operate and allows the user to make multiple measurements on the fly.

Arterial injuries: a sonographic approach.

Acute arterial emergencies can arise from direct traumatic injury to the artery or be spontaneous. This article emphasizes the various presentations of arterial emergencies. These include acute arterial occlusions; excessive bleeding; and hematoma formation caused by penetrating arterial wall injuries, pseudoaneurysms, and arteriovenous fistulas.

From the RSNA refresher courses: MR imaging of aortic and peripheral vascular disease.

Acquired diseases of the aorta and peripheral arteries are common. Owing to technical advances, magnetic resonance (MR) angiography has become the primary imaging modality for assessment of aortic and peripheral arterial disease. Contrast material-enhanced MR angiography is a rapid and robust technique that has emerged as the principal MR angiographic technique for evaluation of vascular disease.

Endovascular stent-graft repair of a pulmonary artery-bronchial fistula.

Herein the authors present a case of a 51-year-old man who presented with dramatic angiographically demonstrated massive hemorrhage from a pulmonary artery-to-bronchial stump fistula 3 months after right upper lobectomy. The patient was successfully treated with endovascular placement of a covered stent.

TrapEase inferior vena cava filter placed via the basilic arm vein: a new antecubital access.

The authors' experience with the TrapEase vena cava filter deployed via a peripheral arm vein access in five patients is described. The filter placement, employing a 90-cm-long sheath and a modified coaxial dilator, is described in clinical and technical detail. The filter was placed successfully in five patients without complications.
