Objective: Endovascular treatment of a patient with acute embolism of the brachiocephalic artery (BCA) is reported.
Case Presentations: A 70-year-old woman presenting with weakness of the right upper extremity was transferred to our hospital due to acute embolism of the BCA. After the right brachial artery was secured by direct cardiovascular surgery, a balloon guidewire was inserted through the femoral artery and advanced near the thrombus in the BCA, and the balloon at its tip was inflated in the right internal carotid artery. Immediately after this, the thrombus in the BCA migrated to the right common carotid artery and right subclavian artery. The two vessels could be recanalized by endovascular treatment via a guide catheter and via the right brachial artery, respectively.
Conclusion: In endovascular treatment for acute embolization of the BCA, the methods for thrombus retrieval and distal protection have not been established, and the concurrent direct surgery and cooperation by a cardiologist are indispensable.
