The sternocleidomastoid (SCM) artery supplying blood to the SCM muscle has different origins according to its anatomical segment. The authors performed cadaveric neck dissection to review the surgical anatomy of neurovascular structures surrounding the carotid artery in the neck. During the dissection, an unusual finding was cited in which the SCM artery supplying the middle part of the SCM muscle originated from the lingual artery (LA); it was also noted that it crossed over the hypoglossal nerve (HN). There have been extremely rare reports citing the SCM artery originated from the LA. Though the elevation of the HN over the internal carotid artery was relatively high, the vascular loop crossing over the HN was very close to the carotid bifurcation. Special anatomical consideration is required to avoid the injury of the HN during carotid artery surgery.

Carotid duplex ultrasound is commonly used to diagnose various carotid artery diseases due to it being noninvasive and easy to perform. Carotid atherosclerosis is a major indicator for the need to perform carotid duplex ultrasound, which can determine the degree of stenosis, plaque characteristics, and intima-media thickness. It can also be used to screen and follow-up after carotid revascularization. Here we discuss the standard techniques, interpretations, and clinical indicators for carotid duplex ultrasounds.

We report a case of recurred Takayasu,s arteritis.The patient was 28-year-old female underwent aorto-left common carotid and aorto-left subclavian bypass graft replacement 1 year ago.Unfortunately, she was readmitted because of newly developing angina and both eye claudication severe headache. Aorto-coronary angiogram showed complete obstruction of left common carotid artery ,stenosis of right carotid artery bifurcation and ostial stenosis of right coronary artery.Bilateral carotid arteries bypass graft with great saphenous vein and right coronary artery bypass graft with right internal mammary artery were done at same the time and she discharged after 21 days without any problem.

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.

현재 경동맥 내막절제술 시행을 위한 경동맥 협착증의 정도 측정에는 디지털감산조영술(DSA), 회전조영술(rotational angiography), 컴퓨터단층조영술(CTA) 및 자기공명조영술(MRA)로부터 얻어진 경동맥의 투영 영상을 이용하여 북미, 유럽 표준 및 총경동맥 방법이 사용되고 있다. 본 논문에서는 기존의 기계적인 측경기를 이용하는 전형적인 경동맥 협착 측정 방법의 단점을 극복하고, 측정자간의 변화율을 최소화하기 위해 자기공명조영술의 단면 영상을 사용하고 컴퓨터화한 새로운 협착증 정도 측정 방법을 개발하였다. 영상 분할에 사용되는 방법중 가장 널리 사용되고 효율적인 명암값 임계치 방법을 사용하여 경동맥 및 동맥의 내강을 분할하였다. 또한, 각 증례의 측정된 총경동맥의 혈관두께를 사용하여 분할된 경동맥으로부터 혈관을 제거 하였고, 혈관이 제거된 경동맥을 혈류 영역과 플라그 영역으로 분할하였다. 각 단면 영상에서의 경동맥 협착증 정도 측정은 (분할된 플라그 영역/혈류영역 및 플라그를 합한 면적) * 100% 식으로 계산된다.

In this study, 230 subjects of medical examination were investigated to figure out the relationship with common carotid artery intima-media thickness and cardiac diastolic function. In addition, the change in the carotid artery intima-media thickness according to the presence or absence of metabolic syndrome was examined. As a result of the study the carotid artery intima-media thickness was thick as the age increased and there was a large difference in those in their 60s and over. There was no gender difference. As for metabolic syndrome the carotid artery intima-media thickness was thicker in the study subjects with high blood pressure diabetes and dyslipidemia. The correlation between the carotid artery intima-media thickness and diastolic function indexes was significant. As a result of hierarchical regression analysis the thicker the intima-media thickness in the carotid artery the lower cardiac diastolic function.

Objective : This study was carried to make out the connection between cerebral artery blood flow velocity and ischemic theory that presumed the cause of Bell's palsy. Method : We measured cerebral artery blood flow velocity each external carotid artery, internal carotid artery, common carotid artery, siphon, superficial temporal artery by TCD to 20 patients who diagnosed as facial nerve palsy from march 2001 to July 2001 and all objectives devided two groups as palsy side. A group is right side facial nerve palsy and B group is left facial nerve palsy. Results : 1. There is no effective change of blood flow in external carotid artery either A, B group. 2. There is no effective change of blood flow in internal carotid artery either A, B group. 3. There is no effective change of blood flow in common carotid artery either A, B group. 4. There is no effective change of blood flow in siphon artery either A, B group. 5. There is no effective change of blood flow in superficial temporal artery either A, B group.

Objective: Although chronic carotid artery occlusion seems to be associated with significant risk of ischemic stroke, revascularization techniques are neither well established nor widespread. In contrast, extracranial-intracranial bypass is common despite the lack of evidence regarding neurological improvement or prevention of ischemic events. The aim of current review is to evaluate the effectiveness of various methods of recanalization of chronic carotid artery occlusion. Methods: Comprehensive literature search through PubMed, Scopus, Cochrane and Web of Science databases performed. Various parameters were assessed among patients underwent surgical, endovascular and hybrid recanalization for chronic carotid artery occlusion. Results: 40 publications from 2005 to 2021 with total of more than 1300 cases of revascularization of chronic carotid artery occlusion have been reviewed. Further parameters were assessed among patients underwent surgical, endovascular and hybrid recanalization for chronic carotid artery occlusion: mean age, male to female ratio, mean duration of occlusion before treatment, rate of successful recanalization, frequency of restenosis and reocclusion, prevalence of ischemic stroke postoperatively, neurological or other symptoms improvement and complications. Based on proposed through reviewed literature indications for revascularization and predictive factors of various recanalizing procedures, an algorithm for clinical decision making have been formulated. Conclusions: Although treatment of chronic carotid artery occlusion remains challenging, current literature suggests revascularization as single option for verified neurological improvement and prevention of ischemic events. Surgical and endovascular procedures should be taken into account when treating patients with symptomatic chronic carotid artery occlusion.

Variations in the vascular anatomy of the carotid triangle have been reported in current scientific literature. The carotid arteries, being the major feeding arteries of the head and neck deserve special importance and protection from iatrogenic injury during radiological evaluations and surgical interventions. The present study was carried out over a period of 4 years from 2012-2016 to assess the variant anatomy of external carotid artery. The external carotid artery and its branches were dissected bilaterally in 40 formalin embalmed cadavers. The external carotid artery was traced from its origin to termination and variations in the branching pattern as well as the level of the carotid bifurcation were observed and analysed. A higher carotid bifurcation was observed in 25% cases. The linguofacial trunk was the commonest variation noted in the branching pattern seen in 20% cases. A single case of unilateral thyrolinguofacial trunk was also observed. The external carotid artery gave rise to accessory branches in 7.5% cases namely the superior laryngeal, accessory ascending pharyngeal and masseteric branches. A slender branch to the internal jugular vein was also observed in one case. These findings may provide further insight into the understanding of the vascular anatomy of the carotid triangle to the curious student, the discerning radiologist and the vigilant surgeon to avert complications and help improve overall treatment outcome.
