Does stent overlap influence the patency rate of aortoiliac kissing stents?

Purpose: To determine if the position of kissing stents in the distal aorta has any influence on the patency rate.

Methods: A retrospective review was conducted of 41 patients (22 men; median age 60.8 years, range 44-86) electively treated for atherosclerotic aortoiliac occlusive disease with angioplasty and kissing stents between January 1997 and January 2005.

Kissing stents for treatment of complex aortoiliac disease.

Objectives: to determine medium term technical and clinical success of kissing stents for aortoiliac occlusive disease.

Design: retrospective study.

Subjects: twenty-five patients presenting with intermittent claudication (IC) or critical limb ischaemia (CLI) due to aortoiliac disease (41 complex stenoses, 8 occlusions).

Revisiting the cardiac versus thoracic pump mechanism during cardiopulmonary resuscitation.

The mechanism of forward blood flow due to external chest compressions during cardiopulmonary resuscitation (CPR) remains controversial, with the main theories being based on either a cardiac, or thoracic pump mechanism. Both potential mechanisms are well investigated by echocardiographic assessment. In the present case, a postoperative complication of cardiac tamponade that was detected by a thoracoabdominal CT-scan, led to cardiac arrest with subsequent successful CPR over 15 min until definitive surgical management was performed.

Detection and characterization of intracranial aneurysms with MR angiography: comparison of volume-rendering and maximum-intensity-projection algorithms.

Objective: The purpose of this study was to compare volume rendering and maximum intensity projection as postprocessing techniques of MR angiography in the detection and characterization of intracranial aneurysms.

Materials And Methods: Three-dimensional time-of-flight MR angiography studies performed in 82 patients were retrospectively evaluated by two independent reviewers who were unaware of digital subtraction angiography findings, the standard of reference. Panoramic maximum-intensity-projection and volume-rendered angiograms were produced from each data set to investigate the presence of underlying aneurysms.

A novel vacuum device for extremity immobilisation during digital angiography: preliminary clinical experiences.

Our objective was to develop and evaluate a non-invasive device for rigid immobilisation during extremity angiography. The patented BodyFix immobilisation device (Medical Intelligence, Schwabmünchen, Germany) consists of a vacuum pump connected to special cushions and a plastic foil that covers the body part to be immobilised. First, the patient's extremity is covered by a thin plastic bag and then wrapped in one of the cushions, placed on the top of the therapy couch, and covered with the plastic foil.
