title: Is It Possible That This Patient is Asymptomatic? The Role of Multidetector CT Angiography in Detection of Ulcerated Plaques in Patients with Asymptomatic Carotid Stenosis: Case Report.
abstract: BACKGROUND
  Although intervention in patients with symptomatic carotid disease is generally accepted as beneficial, the management of asymptomatic disease is still controversial. We wanted to introduce and discuss treatment options in a patient with asymptomatic carotid stenosis and high embolic potential lesions of common and internal carotid artery detected by multidetector computed tomography (MDCT).
  
  
  METHODS
  A 78-year-old female patient was admitted to our institution for diagnostics and surgical treatment of asymptomatic high-grade carotid stenosis. Upon admission, color duplex ultrasonography of the carotid arteries revealed the left common carotid artery (CCA) stenosis of 50% and the ipsilateral internal carotid artery (ICA) stenosis of 60%, while the right CCA was narrowed by 60% and the ipsilateral ICA by 80%. Because of the left subclavian artery (LSA) occlusion, also described by ultrasonography, MDCT angiography was performed to assess arterial morphology for possible angioplasty. In addition to LSA occlusion, MDCT angiography surprisingly revealed significant left CCA (>80%) and ICA (>70%) narrowing by ulcerated plaques with high embolic potential. Surgical treatment of the left CCA and ICA was indicated and Dacron® tubular graft interposition was performed. The postoperative course was uneventful and the patient was discharged from the Institute on the third postoperative day. After the six-month follow-up the patient was doing well with well-preserved graft patency. Conclusion Although color duplex ultrasonography is reliable and safe imaging modality in carotid stenosis diagnosis, MDCT angiography plays a significant role in patients with asymptomatic carotid stenosis since plaques with high embolic potential could be detected, which, if left untreated, could have severe neurological ischemic consequences.
