Case ReportsPercutaneous retrieval of a right atrioventricular embolus.
Percutaneous retrieval of a 12-cm-long serpiginous clot lodged in the right atrium and ventricle is reported. Following bilateral common femoral vein puncture, a Bird's Nest cava filter was first positioned ready to deploy immediately below the renal veins via the right femoral vein. ⋯ The filter was immediately deployed, leaving the clot trapped inferior to the renal veins, in the cava and left iliac vein. The patient remained well and asymptomatic at discharge.

Case ReportsEntrapment of J-tip guidewires by Venatech and stainless-steel Greenfield vena cava filters during central venous catheter placement: percutaneous management in four patients.
We present four patients in whom bedside placement of a central venous catheter was complicated by entrapment of a J-tip guidewire by a previously placed vena cava (VC) filter. Two Venatech filters were fragmented and displaced into the superior VC or brachiocephalic vein during attempted withdrawal of the entrapped wire. Two stainless-steel Greenfield filters remained in place and intact. Fluoroscopically guided extraction of both wires entrapped by Greenfield filters was successfully performed in the angiography suite.
