Paradoxical venous air embolism detected with point-of-care ultrasound: a case report
We present a case of a critical care patient who presented sudden clinical hemodynamic deterioration after the removal of central venous catheter. Hemodynamic evaluation with point-of-care ultrasound (POCUS) showed bubbles in both right and left heart cavities wherewith air embolism facilitated by heart septal defect was suspected. Therefore, the patient was reintubated, supported with vasopressors and a new CVC was inserted to proceed with air aspiration. Shortly after, the patient ’s hemodynamic status improved in terms of vital signs stabilization. 6 h after the event with optimal perfusion markers and diminished sed...

Inadvertent Arterial Placement of Central Venous Catheters: Systematic Review and Guidelines for Treatment
Publication date: Available online 14 September 2019Source: Journal of Vascular and Interventional RadiologyAuthor(s): David L. Dornbos, Shahid M. Nimjee, Tony P. SmithAbstractInadvertent arterial placement of central venous catheters carries serious sequelae, including pseudoaneurysm development and stroke. Although numerous strategies for therapeutic repair after arterial injury have been employed, no treatment provides a definitive standard of care. All articles published between January 2000 and July 2018 involving the placement of central venous catheters in the brachiocephalic or subclavian arteries, carotid artery, ...

Significance of Echocardiographically Detected Central Venous Catheter Tip –Associated Thrombi
Conclusions In this sample with CVC tip–associated thrombi but without PFO or other intracardiac shunts, no embolic or other complications were detected, regardless of anticoagulation status. These data suggest a benign course for such thrombi and that anticoagulation, catheter removal, thrombectomy, and thrombolysis may be unnecessary when catheter tip–associated thrombi are incidentally detected on echocardiography.
