Figure 3 (A) Angiography performed with a JR4.0 catheter (long arrow) demonstrates the central venous catheter (short arrow) malpositioned within the left subclavian artery. (B) A 5.0×8 mm NC TREK balloon (long arrow) was continuously inflated to achieve temporary flow occlusion. A 6F ExoSeal vascular closure device (Cordis) (short arrow) was then deployed through the malpositioned central venous catheter and gradually withdrawn to close the injured vessel. (C) Postoperative follow-up angiography shows no evidence of arterial aneurysm or dissection.
