Flexible Subclavian Artery Closure for an Inadvertent Injury to the Internal Mammary Artery During Internal Jugular Vein Catheterization

Central vein catheter （CVC） placement, which is widely utilized in clinical departments, is also highly important in preoperative preparations for radiofrequency catheter ablation （RFCA）. The internal jugular vein or subclavian vein is the routine target. Arterial injury is not uncommon during the procedure but is potentially devastating in spite of the safety and advantages of the Seldinger technique. Compressing of the airway by a hematoma, as well as hemothorax, pseudoaneurysm, arteriovenous fistula, stroke, and even death, has been well-described.

Intramural Hematoma versus Thrombus： Radiation-induced Heart Disease Results in Mass Formation after Radiofrequency Ablation

Radiofrequency catheter ablation （RFCA）,albeit an effective therapy for drug-refractory atrial fibrillation （AF）,can be associated with complications in 3.9-22.0% of cases, of which cerebrovascular embolization,cardiac tamponade,and pulmonary vein stenosis are more common,and atrial hematoma is more rare.Here,we presented a case describing an elderly woman diagnosed with an intramural left atrial hematoma after AF ablation.
