The optimal surgical approach to the patients with coronary artery disease combined with carotid artery stenosis is controversial. We report two cases of successful surgical management of the patients with combined obstructive coronary and carotid artery disease. The first case was a 69-year-old female who had unstable angina pectoris and a past medical history of left carotid endarterectomy. She was revealed to have triple vessel coronary disease and nearly total occlusion of right internal carotid artery. She was undergone staged right carotid endarterectomy 10 days before coronary bypass surgery. The second case, a 54-year-old male with a past medical history of left hemiparesis and dysarthria, was admitted due to unstable angina pectoris. He was revealed to have triple-vessel coronary disease and more than 90% stenosis of left internal carotid artery and 50% stenosis of right internal carotid artery. In the latter case, a combined coronary bypass surgery and left carotid endarterectomy was done. In both cases, postoperative neurologic complications were not observed.

Purpose : Stroke is one of the leading causes of death in Korea. Atherosclerotic disease in the carotid artery bifurcation is the most common cause of stroke. The carotid artery calcification is easily appreciated by CT (Computed tomography). CT is often taken in a dental hospital for the diagnosis of inflammation, injury, cyst or tumor on maxillofacial region. However, there was no report of carotid artery calcification on CT in dental patients. This study was to determine the prevalence of carotid artery calcification on CT in dental patients. Materials and Methods : The presence of carotid artery calcification was evaluated by an experienced radiologist on CT scans of 287 patients (166 males, 121 females, average age 42, range 6 to 86 years) and the medical history of the patient and the interpretation of CT were reviewed. Results : Carotid artery calcification was detected on CT scans of 57 patients (19.8%; 35 males, 22 females). All the male patients with carotid artery calcification were older than 50, and all the female patients with carotid artery calcification were older than 60. Among the 57 patients, 10 had Diabetes mellitus, 20 had cardiovascular disease, 3 had history of stroke and 3 underwent radiation therapy for head and neck cancer. Carotid artery calcification was not included in the interpretation of CT of dental patients except one patient. Conclusion : The prevalence of carotid artery calcification on CT of dental patients was about 20% in this study. Carotid artery calcification should be included in the interpretation of CT of dental patients.

Duplex sonography has been used to non-invasively diagnose carotid artery disease and to follow up patients with this disease. In carotid artery disease, carotid mobile thrombus and dissection are rarely detected by duplex sonography in patients with cerebrovascular events. In particular, carotid dissection occurs when a small tear forms in the tunica intima and makes 2 lumens in the carotid artery, including true and false lumens. This study reports 3 rare cases of carotid mobile thrombus, spontaneous carotid dissection, and carotid dissection in Takayasu arteritis.

The virtual angioscopy was implemented using MR angiography image of carotid artery Inside of the carotid artery is one of the body region not accessible by real optical endoscopy but can be visualized with virtual endoscopy. In order to determine the navigation path, we segmented the common carotid artery and internal carotid artery from the MR angiography image. We used the coordinates as a navigation path for virtual camera that were calculated from medial axis transformation. We used the perspective projection and marching cube algorithm to render the surface from volumetric MRA image data. A stroke occurs when brain cells die because of decreased blood flow to the brain. The carotid artery is the primary blood vessel that supplies the blood flow to the brain. Therefore, the carotid artery stenosis is the primary reason of stroke. The virtual angioscopy is highly recommended as a diagnosis tool with which the specific Place of stenosis can be identified and the degree of stenosis can be measured qualitatively. Also, the virtual angioscopy can be used as an education and training tool for endoscopist and radiologist.

Extracranial carotid artery disease is rare and closely related to cardiovascular morbidity and mortality.We experienced one case of surgical treatment of left common carotid artery stenosis using internal shunt.The patient was 54-year-old female presented as headache and dizziness for about 2 years.On Doppler ultrasound, an atheromatous plaque was noted along the posteromedial wall of left common carotid artery resulting in luminal narrowing in about 75s of cross section area.The atheroma was resected through carotid endarterectomy, measured about 5.2cm in length. Postoperative course was uneventful and she was discharged in good condition.

Objectives : This study was aimed to clarify the relationship between the dampness-phlegm diagnosis and internal carotid artery stenosis by measuring carotid artery sonography in cerebral infarction patients. Methods : One hundred eighty subjects were recruited from the patients admitted to the Department of Internal Medicine at Kyunghee university oriental medical center from September 2008 to July 2010. We assessed one hundred eighty patients' carotid artery sonography data and diagnosed dampness-phlegm by oriental medical diagnosis. then, analyzed their characteristics, risk factor, lifestyle, metabolic syndrome, body mass index, Waist/Hip ratio(W/H ratio) and dampness-phlegm diagnosis. Results : On the demographic variables of the patients, age, smoking, W/H ratio and dampness-phlegm group were significantly higher in severe internal carotid artery(ICA) stenosis group than in the control group. According to the significant difference in dampness-phlegm group, we analyzed dampness-phlegm related index for pattern identifications by ICA stenosis. As a result, sputum, bowel sound, chest discomfort, slippery pulse were significantly higher in the severe ICA stenosis group than in the control group. In multivariate analysis, dampness-phlegm group showed close relationship with severe ICA stenosis group. Conclusion : According to the analysis, significance between dampness-phlegm diagnosed patients group and severe ICA stenosis were clarified. These results can be utilized in the future as a basis material.

The carotid artery is one of the main vessels supplying blood to the brain. Carotid artery stenosis is mostly caused by atherosclerosis, a disease where cholesterol is deposited in the arterial blood vessels. Tremor refers to rhythmic shaking of a body part. Tremor is a symptom of many diseases, including Parkinson's disease, essential tremor, orthostatic tremor, cerebellar disease, peripheral neuropathy, and alcohol withdrawal. Tremors may be classified as postural, rest, and action tremors. Tremor of a patient with stenosis of the left carotid artery decreased with acupuncture treatment. The acupoints were GB20, TE17, GV8 and GV11. This case shows that the acupuncture treatment is effective against tremor.

In an effort to reduce the stroke rate of patients after coronary artery bypass, many authors have studied the prevalence of the extracranial carotid disease and its role in determining neurologic morbidity and mortality rates. From April 1992 to August 1993, Seventy-five patients undergoing coronary artery bypass were preoperatively evaluated for presence of carotid and femoral stenosis by Duplex sono. Among them, fourteen patients was positive by Duplex sono and overall prevalence of carotid or femoral stenosis was 18.7%. And significant carotid stenosis [ > 60% ] had proved to be in 3 patients [ 4.0% ].Prophylatic bilateral carotid endarterectomy was performed in one patient, at 5 months prior to and , 1 week prior to coronary artery bypass respectively. Their mean age was 57.6 years [ ranged from 40 to 70 years] and were composed of 10 males and 4 females. There was no postoperative morbidiry and mortality related to neurologic complications. Our data, although small, suggest that preoperative carotid screening is helpful to determine patients at high risk of stroke, and significant simultaneous carotid and coronary atherosclerosis should be corrected in selected patients by staged operations when feasible.

Fibromuscular dysplasiais an uncommon condition of idiopathic, non-inflammatory and non-atherosclerotic disease of the musculature of arterial walls. The disease is rare, but it commonly affects young and middle aged women. Isolated intracranial cerebral fibromuscular dysplasia is extremely rare because cerebral fibromuscular dysplasia usually affects extracranial vessels. A 20-year-old woman was admitted with light hemiplegia and global aphasia. Brain MRI and MRA demonstrated acute left middle cerebral artery territory infarction with a multifocal stenosis and dilatation of the left middle cerebra artery and left internal carotid. The characteristic conventional cerebral angiographic findings demonstrated a typical string-of-beads appearance in the left distal internal carotid artery and proxiaml portion of the left middle cerebral artery, which suggested a medial type fibromuscular dysplasia. We report a case of isolated intracranial fibromuscular dysplasia with left middle cerebral artery territory infarction. Fibromuscular dysplasia should he considered as a stroke risk factors in children and young adults, especially in patients with no known cardiovascular risk factors.

Behest's disease is manifested as ulcers present in oral cavity, on external genital organ, orbital area, and skin. This disease could also cause other symptoms by invading the cardiovascular system, respiratory system, gastrointestinal system, central nervous system, and urogenital system. It is very rare for Behcet's disease to be accompanied by carotid artery aneurysm and intestinal perforation. We report a patient with Behcet's disease, who is diagnosed with symptoms and pathological findings as haying carotid artery aneurysm and intestinal perforation at the same time. The patient underwent operation for the aneurysm and the intestinal perforation.
