  • Objectives: To completely excise a malignant tumor which invades carotid artery walls, the resection and reconstruction of the carotid artery is essentially required. In most of the cases, interposition graft using a saphenous vein has been performed, however the vessel caliber discrepancy between a common carotid artery and the saphenous vein can result in a problem on surgical technique. We have introduced and evaluated a new titanium hemoclip tailing method to overcome vessel caliber discrepancy in interposition saphenous vein graft for carotid artery resection in the treatment of head and neck cancers. Method: After carotid artery resection, the calibers of the proximal common carotid artery and the vein were compared, and an orifice of the common carotid artery was gradually reduced to a little larger than or the same size as the orifice of the vein by using the titanium hemostatic clip. Subsequently, the common carotid artery was connected to the vein through anastomosis. The same method was also applied to the distal anastomosis site. There after, the vessels were connected through the anastomosis, and a circulation was restored by releasing a vascular clamp. Then, a titanium hemostatic clip-applied redundant portion on the outside of carotid artery was sutured by the blanket edge suture method, using 6-0 Prolene. Results: We have experienced this method in two patients with recurrent squamous cell carcinoma and neuroblostoma, respectively. The interposition saphenous vein graft of these patients was found to maintain good patency on the follow up angiography after one year, and they had no specific vascular complication, such as atherosclerosis. Conclusion: This method made it possible to simply perform the interposition saphenous vein graft (ISVG) within a short time and, therefore, was very useful for shortening the duration to block circulation.

  • Aneurysms of the extracranial carotid artery are rare. This is a case report of the rapidly expanding false carotid aneurysm at left common carotid artery, which was repaired surgically with internal shunt This 20 year old male patient had a large pulsatile mass on left lateral aspect of neck at the time of admission. About 1 month before admission, he had received a trauma on left neck by glass piece and noted massive blood loss. And its skin of lesion was sutured simply at local clinic and well healed. 10 days before the admission, he had the sudden onset of the adult thumb sized and pulsatile mass and the mass had been enlarged more and more to the adult first-sized one. The cervical film showed a egg-sized and soft tissue mass. There was systolic bruit on the mass. The diagnosis was confirmed with the angiogram of left carotid artery and this showed the man`s thumb tip-sized extravasation at the point 2 Cm below the bifurcation of Internal and external carotid arteries. The emergency operation was performed by the internal shunt with carotid artery. The aneurysm was enclosed with the adventitia and carotid sheath, and the intima and media were Intact and had the opening of 0.5 cm in diameter. The opening was sutured by the one-hand mattress suture method and firmed with the Aron Alpha-A "Sankyo." The postoperative course was uneventful and the patient was discharged with good general condition.

  • Penetrated injury of common carotid artery (CCA) is rare and extremely lethal. Carotid artery injury tends to bleed actively and potentially occlude the trachea. It can cause fatal neurological complications. An accurate diagnosis and adequate treatment are very needed to the successful outcome of the penetrating vascular injury in zone 1, 2, and 3 of the neck. Open surgical treatment is more invasive and complicated than endovascular treatment. We experienced a case with penetrating injury in neck zone 2. Here, we report the case successfully treated with endovascular stent graft technique.

  • 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.

  • A patient was 29 year old house wife who was admitted to the Yonsei University Medical Center on 6 th of Nov., in 1970, with chief complaints of complete loss of bilateral visual acuity, generalized weakness, frequent palpitations, claudication of masseter muscles and intermittent fainting. These symptoms were developed 5 years prior to admission. Physical finding on admission revealed complete loss of bilateral visual acuity, absence of both radial and carotid pulse, but there was good femoral and popliteal pulse. She couldn't open her mouth as she desired and had weakness of mastication. Radiological findings of plane chest PA were not significant. Aortogram(Cineangiogram) showed non-visualization of both carotid and subclavian arteries. It showed only innominate and interal mammary artery preoperatively. The operative findings were as follows: There were complete obliterative changes in both common carotid and subclavian arteries, and periarteritis in the innominate artery. Tube Dacron Prosthesis Bypass with V-arm between innominate artery and both common carotid arteries was performed after thromboendarterectomy. Histopathological finding of the thromboend arterectomy specimen was compatible with pulseless disease, which showed marked fibrous thickening of intima and a diffuse inflammatory cell infiltration of the whole layers. Her postopererative course was uneventful. Follow up aortogram(Cineangiogram) was taken on 11th postoperative day, which revealed both common carotid arteries patent. Her preoperative Subjective symtoms disappeared remarkably, such as her visual acuity improved much, fainting and vertigo disappeared completely and she can go to bath room without difficulty and help. Another patient was 34 year old house wife who was admitted on August, 1964 with chief complaints of frequent fainting and progresive visual loss. She was operated only thromboendarterectomy of both common carotid arteries. Postoperative course was smooth and subjective symptoms were disappeared.

  • The purpose of this study was to analyze the effect given to the variable details which disturb the flow of blood in brain artery disease through Aerobic exercises. It chose the subjects of study : 5 persons in an exercise group and 5 persons in a non-exercise group. Peak brain blood velocity, mean velocity, and resistance & artery stricture ratio were measured with TCD, measure machine for brain artery blood flow. The conclusion of the study was as follows: 1. At pre-test of an exercises group and a non-exercise group, PBV, MBV, BRI, ASI of a non-exercise group were showed much lower in the variation of left common carotid artery(LCCA). 2. At post-test of an aerobic exercises group and a non-exercise group, PBV, MBV, BRI, ASI of a non-exercise group were showed just a little decrease ratio but were not significant different in the variation of left common carotid artery(LCCA). Viewing on the base of these result, continuing exercises promote the functional improvement of the heart blood system and were showed the positive variation of artery stricture ratio according to brain blood flow velocity, the pulse and resistance or blood velocity. Therefore programs for prescriptions through aerobic exercises must be developed in many ways.

  • Prior knowledge of arterial supply to the head and neck is of substantial importance for well-planned surgeries involving the concerned region. We are reporting an unusual and rare variation in the branching pattern of external carotid artery in a 60-year-old female cadaver. A common trunk known as thyrolinguofacial trunk, originating from the anterior surface of the external carotid artery (right and left) giving of superior thyroid artery and a linguofacial trunk during a routine neck dissection. The linguofacial trunk then divided into a lingual and a facial artery. Vascular abnormalities are usually detected either on the dissection table or by the radiologists during imaging or accidently during surgeries leading to serious consequences.

  • In the present study, the characteristics of blood flow inside a carotid artery numerically investigated with shear rate specific blood viscosity. To simulate the blood flow with a patient-specific arterial geometry, the geometry of a carotid artery was constructed from 2D rain MRA data. The measured data of blood flow velocity at the common carotid artery were used as boundary conditions of the simulation. For the blood rheology data to be used in the simulation, the patient specific blood viscosity over the whole ranges of shear rate was obtained using $BioVisco^{TM}$. From the numerical results of the blood flow in the carotid artery, the increase of blood viscosity and the decrease of wall shear stress could be found in the carotid bifurcated region, more specifically at the post-plaque dilated region. These characteristics of blood viscosity and wall shear stress can be used more precisely and efficiently to predict the region vulnerable to plaque growht or thrombosis on top of the plaque.

  • 1. Objectives The purpose of this study was to investigate the correlation of Metabolic syndrome(MetS) and Intima-media thickness(IMT) of common carotid artery with Sasang constitution. 2. Methods 197 subjects who had taken health examinations and diagnosis of Sasang constitution from Jan 1, 2006 to Dec 31, 2006 at East-west health examination center of Kyung-Hee medical center were included and underwent B-mode ultrasonography for measurement of intima-media thickness of common carotid arteries. MetS was defined by the criteria of the criteria of the National Cholesterol Education Program Adult Treatment Panel III. 3. Results and Conclusions Mean intima-media thickness of common carotid artery was significantly higher in subjects with MetS compared with control subjects($0.070{\pm}0.017$ vs $0.063{\pm}0.014cm$) and a significant trend towards increased IMT was observed with increasing numbers of metabolic syndrome components(r=0.331, p=0.000). After adjustment for age and sex, IMT of common carotid arteries was significantly different among three constitutional groups (Soyangin:$0.065{\pm}0.015cm$, Taeumin:$0.068{\pm}0.016cm$, Soeumin:$0.056{\pm}0.010cm$), however, after adjustment for age, sex and existence of metabolic syndrome, there was no significant different. But, factor of Taeumin was the effective determinant of the increase of mean IMT of common carotid arteries.
