Incidence of extracerebral paradoxical embolisms in patients with intracardiac shunts.

Background: Although extracerebral embolism accounts for 5-10% of all paradoxical embolisms, it still remains a ghostlike entity in cardiovascular pathophysiology. The aim of this brief report was to analyze the profile of patients with paradoxical extracerebral embolism and intracardiac shunts, and the role of shunt closure on the recurrence of extracerebral paradoxical embolism (EPE) in a population of patients evaluated for patent foramen ovale (PFO)/atrial septal defect (ASD) transcatheter closure.

Methods: From July 2003 to December 2006, 150 patients (mean age 51.

Combined percutaneous aspiration thrombectomy and rheolytic thrombectomy in massive subacute vena cava thrombosis with IVC filter occlusion.

Purpose: To report the combined use of percutaneous aspiration thrombectomy and rheolytic thrombectomy in the setting of extensive inferior vena cava (IVC) thrombosis and filter occlusion.

Case Report: A 28-year-old paraplegic man with a vena cava filter in situ for previous deep vein thrombosis (DVT) was referred to our center for evaluation of dyspnea and right leg edema and swelling. Computed tomography excluded a pulmonary embolism and revealed severe, massive DVT of both iliac veins and the IVC, including the vena cava filter.

An improved technique for gaining radial artery access in endovascular interventions.

We present a simple technique to avoid time loss and potential dangerous maneuvers for catheterization of the radial artery in endovascular interventions. If any difficulties are encountered when advancing the guide wire after the arterial puncture using standard transradial kits, we found it useful to routinely use a 60-mm polyethylene radial pressure line catheter like the Leader Cath (Vygon, Ecquen, France), which is more flexible and less traumatic than short catheters and are usually available in the standard hydrophilic transradial kit. With the 20-gauge needle within the arterial lumen, it is sufficient to advance the guide wire 3 or 4 cm, followed by the insertion of the radial pressure line catheter for administering a vasodilator cocktail.
