Takayasu's arteritis (TA) is a chronic vasculitis involving the aorta and its main branches, the pulmonary arteries, and the coronary tree. Here we report a case of TA complicated by severe stenosis of the left coronary ostium with multivessel brachiocephalic involvement. A combination of these abnormalities could complicate underlying illness in patients, posing an increased risk of surgical morbidity. Simultaneous surgical treatment of the ascending aorta to left carotid artery bypass and coronary artery bypass using the great saphenous vein were performed. We discuss the choice of simultaneous surgery and the options for surgical treatment of complicated lesions due to TA.

BackgroundCarotid body tumor surgery is associated with various complications. However, intraoperative cardiac arrest is very rare and no more than 10 cases have been reported.Case descriptionA 58-year-old woman diagnosed with bilateral carotid body tumors underwent right carotid body tumor surgery. Sudden cardiac arrest occurred during the resection and was attributed to carotid sinus hypersensitivity. The patient recovered after prompt treatment and the tumor was removed completely with no complications.ConclusionCardiac arrest attributed to carotid sinus hypersensitivity during carotid body tumor resection is very rare. Proper treatments can reverse intraoperative cardiac arrest. If carotid sinus hypersensitivity is detected preoperatively, prophylactic temporary pacemaker implantation may be appropriate.
