| description | Anginal chest pain after implantation of coronary stents in bypass grafts is a concern because it suggests the possibility of occlusion. Coronary angiography is the definitive method for determining patency of a stent; however, this procedure is relatively contraindicated in a patient receiving warfarin sodium, who has a therapeutic international normalized ratio. An alternative method for determining patency of a stent is by ultrafast computed tomography. This new, minimally invasive technique shows promise for determining blood flow within the large vessels of the thorax. Herein we describe a case in which a metallic stent placed in a vein graft was noninvasively established to be patent, despite chest pain in the patient. This method may be clinically applicable for determining patency of stents in vein grafts in the setting of patients with chest pain who have undergone complete anticoagulation. |
