Doppler ultrasound can be used to detect almost all arteries of the face before injecting the hyaluronic acid (HA) filler. The relatively more dangerous sites of filler injection are the glabellar wrinkle, forehead, temple, nose, and nasolabial fold area, and it is recommended to map the vasculature of these areas by Doppler ultrasound before performing filler injection. The Doppler ultrasound detection method is included as a video. Internal carotid arterial branches, the supratrochlear, supraorbital, and dorsal nasal arteries, and external carotid arterial branches, the superficial temporal and facial arteries, are very important arteries when injecting HA filler; thus, Doppler ultrasound detection is recommended.

The patient was 47-year-old male who had suffered from aphasia and hemiplegia of the right side, but mental state was alert. On physical examination, BP was 130/80 mmHg in the right arm, but not checked in the left arm. The pulses of the left common carotid, brachial, and radial arteries were not palpable. The pulses of the right femoral, popliteal, and dorsalis pedis arteries were weakly palpable. Brain CT Scan revealed cerebral infarction of the left hemisphere. Aortogram showed occlusion of the left common carotid, and the right internal carotid and common iliac arteries. Subclavian steal phenomena were observed in the delayed aortogram. Double extra-anatomic bypasses; Axillo-Axillar bypass and Femora-Femoral bypass, were performed in the local anesthesia at two stages, because of risk of major operation under general anesthesia. Postoperatively, all pulses except for pulse of the left common carotid artery were equally palpable. On discharge, the hemiplegia of the right side was improved and able to walk with assistance.

Spontaneous bilateral cerebellar infarction in the territory of the superior cerebellar arteries is extremely rare. Occasionally there have been reports of bilateral cerebellar infarction due to vertebrobasilar atherosclerotic occlusion or stenosis, whereas no report of bilateral cerebellar infarction due to complicated hemodynamic changes. In this report, we present a patient with bilateral cerebral infarctions related to stenoses of bilateral internal carotid arteries, in whom vertebrobasilar system was supplied by multiple collaterals from both posterior communicating arteries and right external carotid artery. We performed stent-angioplasty of bilateral internal cerebral arterial stenosis, and then acute infarction developed on bilateral superior cerebellar artery territories. The authors assumed that the infarction occurred due to hemodynamic change between internal carotid artery and external carotid artery after stent-angioplasty for stenosis of right internal carotid artery.

Congenital absence of the bilateral internal carotid arteries (ICA) is a very rare occurrence. Recognition of this rare anomaly is important, when considering intracranial endovascular interventions in the event of thromboembolic events with revascularization, transsphenoidal surgery, and the surveillance and detection of associated cerebral aneurysms. We report a case of a 25-year-old man who presented with headache since 2 years ago, and was incidentally discovered to have a congenital bilateral absence of ICAs.

배경: 경동맥 내막절제술은 심한 경동맥 협착증이 있는 환자에서 발생 가능성이 높은 뇌졸중을 예방하는 데 효과적인 것으로 알려져 있으나 술 후 사망이나 뇌졸중 등의 심각한 합병증을 유발할 수 있다. 이에 저자들은 경동맥 협착증에 대한 수술적 치료의 결과를 분석하여 향후 수술의 합병증을 줄이고자 본 연구를 시행하였다. 대상 및 방법: 1996년 2월부터 2004년 7월까지 경동맥 협착증으로 한 명의 술자에 의해 경동맥 내막절제술을 시행 받은 74명(76예)의 의무기록을 후향적으로 분석하였다. 결과: 남자가 64명, 여자가 10명이었고 평균연령은 63.6세($40{\sim}77$세)였다. 경동맥 내막절제술만을 시행한 경우가 63예, 내막절제술과 함께 패취를 이용하여 경동맥 성형술을 시행한 경우가 8예, 내막절제술과 함께 경동맥의 일부를 절제한 후 단단 문합한 경우가 5예였다. 수술 중 동맥내 션트는 29예에서 사용되었다. 총경동맥과 외경동맥을 겸자한 후의 평균 내경동맥 역류압은 뇌파의 허혈성 변화가 있었던 25예(A군)의 경우 $23.48{\pm}10.04$ mmHg이었고, 뇌파의 허혈성 변화가 없었던 51예(B군)의 경우 $47.16{\pm}16.04$ mmHg이었다. 두 군 간의 내경동맥 역류압의 평균치는 통계학적으로 차이가 없었으나 (p=0.095) 뇌파의 허혈성 변화가 나타난 환자의 내경동맥 역류압은 모두 40 mmHg 이하였다. 내경동맥 역류압에 관계없이 뇌파의 허혈성 변화가 없으면 동맥내 션트를 시행하지 않고 수술하였다. 합병증은 일시적인 설하신경 마비 4예, 기존의 뇌경색 부위에 발생한 뇌출혈 2예, 경미한 뇌경색 1예, 봉합 부위의 혈액 누출에 의한 혈종 1예, 술 중 과도한 견인에 의해 유발된 것으로 생각되는 후두 부종에 의한 상기도 폐쇄 2예였다. 기존의 뇌경색 부위에 발생한 뇌출혈 2예 중 1예는 응급 수술을 시행한 경우로 뇌출혈이 심해 보존치료 도중 사망하였다. 결론: 경동맥 내막절제술은 수술 사망률이 낮은 비교적 안전한 수술 방법이다. 허혈성 뇌손상을 예방하기 위해 사용되는 동맥내 션트는 내경동맥 역류압보다는 뇌파의 허혈성 변화 여부에 따라 사용되어야 한다고 생각한다. 후두 부종을 예방하기 위해 수술 중 과도한 견인을 피하고 수술 직후 혈압을 엄격히 관리해야 하며, 후두 부종이 의심되면 작은 구경의 튜브를 이용한 기관 삽관이나 응급 기관절개술 등을 통하여 신속하게 기도를 확보해야 한다.

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.

Essential sources of arterial vascularisation in the head and neck region are the left and right common carotid arteries (CCA) and their branches. The left CCA (LCCA) originates from the arch of the aorta and the right CCA originates from the brachiocephalic trunk. In this case report, there was a bilateral higher division of CCA at the plane of the greater cornua of the hyoid bone, unilateral tri-ramification of the LCCA and the left external carotid artery (LECA), and the origin of the linguo-facial trunk and the pharyngo-occipital trunk from the LECA. An aneurysm formed in the distal part of LECA before its termination. In this case, we propose a novel categorization called the punnapatla classification for the anatomical variance branching forms of ECA. These kinds of variations are important to the surgeons, and anaesthetists, during the surgeries of the head and neck.

Purpose: Early detection of carotid stenosis can reduce cardiovascular risk. In this study, the maximum-carotid intima-media thickness (CIMT), the mean-CIMT, and the presence of plaque were examined in healthy young Thai adults. Additionally, correlations between CIMT and cardiovascular risk factors were assessed. Materials and Methods: Left and right carotid arteries of 302 participants(15-45 years old) were scanned, with CIMT measured at the far walls of the common carotid artery, carotid bulb, and internal carotid artery. Demographics and risk factors were assessed using a questionnaire. Ten random participants were re-scanned after 4 weeks. Results: The study included 123 (40.70%) male and 179 (59.30%) female participants. The max-CIMT, mean-CIMT, and plaque thickness were 0.400±0.100, 0.403±0.095 and 1.520±0.814 mm, respectively. Male participants had significantly higher CIMT values for nearly all locations and age groups. The right-sided CIMT values were higher for all locations. The carotid bulb had the greatest CIMT values(0.437±0.178 mm), followed by the common (0.403±0.095 mm) and internal(0.361±0.099 mm) carotid arteries. Plaque was present in 18 locations (1.00%), affecting 15 participants (4.97%). These plaques were found in the right carotid bulb (n=9; 0.50%), left carotid bulb (n=7; 0.39%), and right internal carotid artery (n=2; 0.11%). Adjusted multivariable regression revealed significant positive associations between CIMT and male, increased age and "other" occupation (P<0.05). Conclusion: Both max-CIMT and mean-CIMT were approximately 0.4 mm. Plaque was observed in 4.97% of patients, with an average thickness of 1.5 mm. The most influential risk factors for increased CIMT were sex, age, and occupation.
