혈액투석을 위한 이중도관 삽입 후 생긴 가성동맥류의 치료 1예

Abstract

In patients with end-stage renal disease, cannulation of the central venous system with large-bore dual-lumen catheters is often necessary until a functioning vascular access can be created. However, the technique of placing a dual-lumen catheter can make complication. The right internal jugular vein is the preferred site of hemodialysis catheter placement because its complication rate was lower compared with the subclavian and left internal jugular veins. Common complications include severe bleeding, hematoma formation, pneumothorax and hemothorax, atrial or ventricular arrhythmias, malposition of the catheter, air embolism, secondary infections, and intraarterial placement of the catheter. We report an unusual case of pseudoaneurysm of the superior thyroidal artery complicating an attempt of internal jugular-vein catheterization which was successfully treated by endovascular coil embolization.
