  • Background: Cerebral blood vessels are innervated by sympathetic nerves from the superior cervical ganglia (SCG), and these nerves may influence the cerebral blood flow. The purpose of the present study was to evaluate the neuroprotective effect of superior cervical sympathetic ganglion block in rats that were subjected to focal cerebral ischemia/reperfusion injury. Methods: Eighty male Sprague-Dawley rats (270-320 g) were randomly assigned to one of two groups (the ropivacaine group and a control group). In all the animals, brain injury was induced by middle cerebral artery (MCA) reperfusion that followed MCA occlusion for 2 hours. The animals of the ropivacaine group received $30{\mu}l$ of 0.75% ropivacaine, and their SCG. Neurologic score was assessed at 1, 3, 7 and 14 days after brain injury. Brain tissue samples were then collected. The infarct ratio was measured by 2.3.5-triphenyltetrazolium chloride staining. The terminal deoxynucleotidyl transferase mediated dUTP-biotin nick-end labeled (TUNEL) reactive cells and the cells showing caspase-3 activity were counted as markers of apoptosis at the caudoputamen and frontoparietal cortex. Results: The death rate, the neurologic score and the infarction ratio were significantly less in the ropivacaine group 24 hr after ischemia/reperfusion injury. The number of TUNEL positive cells in the ropivacaine group was significantly lower than those values of the control group in the frontoparietal cortex at 3 days after injury, but the caspase-3 activity was higher in the ropivacaine group than that in the control group at 1 day after injury. Conclusions: The study data indicated that a superior cervical sympathetic ganglion block may reduce the neuronal injury caused by focal cerebral ischemia/reperfusion, but it may not prevent the delayed damage.

  • Objective : Penumbra ACE68 reperfusion catheter is a new large bore aspiration catheter used for reperfusion of large vessel occlusion. The objective of this study was to investigate the efficacy of this catheter in comparison to that of previous Penumbra catheters in patients with acute ischemic stroke related to internal carotid artery (ICA) occlusion. Methods : Data of all eligible patients who received endovascular treatment (EVT) for ICA occlusion using Penumbra aspiration catheters between January 2015 and December 2018 were retrospectively reviewed. After dividing into two groups according to use of penumbra ACE68, baseline characteristics of patients, successful recanalization rate, puncture to recanalization time, and switch to stent base technique rate were assessed. Successful recanalization was defined by a thrombolysis in cerebral infarction (TICI) score ${\geq}2b$ and favorable functional outcome was defined according to modified Rankin scale (score, 0-2). Results : ACE68 reperfusion catheter was used in 29 of 75 eligible patients (39%). The puncture to recanalization time was significantly shorter ($26{\pm}18.2$ minutes vs. $40{\pm}24.9$ minutes, p=0.011) and the rate of switch to stent-based retrieval was significantly lower (3% vs. 20%, p=0.046) in ACE68 catheter group. Moreover, although not statistically significant, the successful recanalization rate was higher (83% vs. 76%, p=0.492) in ACE68 catheter group. Favorable functional outcome was observed in 48% of patients treated with ACE68 reperfusion catheter and in 30% of patients treated using other Penumbra systems (p=0.120). Baseline Alberta Stroke Program Early CT Scores ${\geq}8$ (odds ratio [OR], 9.74; 95% confidence interval [CI], 1.72-54.99; p=0.010) and successful recanalization (OR, 10.20; 95% CI, 1.13-92.46; p=0.039) were independent predictors of favorable outcome. Conclusion : EVT using ACE68 reperfusion catheter can be considered a first-line therapy in patients with acute ICA occlusion as it can achieve rapid recanalization and reduce the frequency of conversion to stent-retrieve therapy.

  • 내경 동맥 박리는 드물기는 하나 소아 허혈성 뇌경색의 한 원인이며, 선행된 외상 후 발생하는 경우가 흔해 두개강 내 보다는 두개강 외에 발생하는 경우가 많다. 건선은 흔한 피부 질환 중 하나이며, 서양인에 비해 동양인에서는 그 빈도가 낮고 다른 전신 질환과 동반되어 보고되기도 한다. 건선은 혈전 색전증과 연관된 허혈성 심뇌혈관계 질환과 연관되어 보고된 바가 있기는 하지만, 혈관 박리와 연관되어 보고된 경우는 드물다. 저자들은 이전에 건선으로 치료 받고 최근 피부 증상이 악화되던 중 우측 반신 마비와 안면 마비가 발생해 내원한 13세 여아에서 자발성 두개강 내 내경 동맥 박리를 진단하여 보고하는 바이다.

  • 심실중격파열 및 좌심실자유벽파열은 급성 심근경색의 주요 합병증들 중의 하나이나 이 치명적인 합병증 둘이 모두 동일 환지에서 발생한 소위 심실이중파열에 대한 외과적 치험예는 거의 보고되고 있지 않고 있다. 저자들은 급성심근경색의 합병증으로 발생한 심실중격파열에 이어 좌심실자유벽이 파열된 환자에서 시행된 외과 치험 1예를 보고하고자 한다. 58세 남자가 급성심근경색으로 전원되었다. 심초음파로 후심실중격파열을 진단 후 대동맥내풍선점프를 넣고 응급수술을 계획하였다. 마취 유도 중 갑자기 환자는 순환허탈에 빠져 심장마사지를 하며 개흉하여 혈심낭에 의한 급성 심장압전과 좌심실 후벽 중간 부위에서 혈액을 분출하고 있는 약 2cm 길이의 세로 방향의 파열을 관찰할 수 있었다. 심폐바이패스를 설치, 혈역학을 안정시킨 후 좌심실 재건술을 시행하였다. 환자의 수술 후 경과는 술 전 심장마비로부터 비롯된 것으로 생각되는 뇌손상으로 지연되었다.

  • 목동맥 스텐트 삽입술은 목동맥 내막절제술에 적합하지 않은 환자에게 시행할 수 있는 목동맥 협착증의 대체 치료법으로 알려져 있다. 목동맥 내막절제술, 혈관성형술 또는 스텐트 삽입술 후에 드문 부작용으로 뇌내출혈이 발생할 수 있고, 이러한 출혈이 발생하는 원인은 대부분의 경우 재관류 손상과 관련이 있는 것으로 추정하고 있다. 이전의 연구에서는 내막절제술과 비교하여 목동맥 스텐트 삽입술 후 뇌내출혈의 빈도가 더 높다고 보고한 바 있다. 본 연구에서는 뇌경색으로 내원한 80세 남자환자를 대상으로 증례보고를 통해 동일 분야 연구에 활용하고자 자료 분석을 하였다. 80세 남자가 갑자기 발생한 오른 팔의 근력저하를 주소로 방문하였다. 왼쪽 속목동맥의 90% 협착이 발견되어 목동맥 스텐트 삽입술을 시행하였고, 시술 후 실시한 뇌 CT에서 시상을 포함하는 후대뇌동맥 영역의 뇌출혈이 뇌실내출혈까지 진행되어 있음을 관찰하였다. 이러한 출혈은 스텐트 삽입술이 시행된 동맥에서 공급될 가능성이 낮은 혈관 영역에서 발생했기 때문에, 이 경우에 내막절제술 시행 후 과다혈류에 의한 출혈과 다른 양상을 확인하였다.

  • Objective : This study was aimed to investigated the correlation between the stroke incidence by day of the week and risk factors in acute stroke patients. Methods : From October in 2005 to October in 2007, 673 acute stroke patients wereincluded. Patients were hospitalized within 14 days after the onset of stroke in DongGuk University International Hospital, Kyungwon University In-cheon Oriental Medical Hospital or the Department of Cardiovascular and Neurologic Diseases (Stroke Center), Kyung Hee University Oriental hospital. We investigated general characteristics, stroke types, age group, educational backgrounds, medical history, lifestyle (the impact of stress, exercise, smoking and drinking) and Sasang constitution according to the stroke incidence by day of the week. Results : After examining each participants with day of the week, the order of days by incidence was Monday, Wednesday, Sunday, Saturday, Tuesday, Thursday and Friday respectively. Monday and Tuesday showed the highest ratio. As the aspect of demographic data of subjects, the group under 55 years and from 55 years to 70 years showed the highest ratio on Monday. In the group between 25 years to 55 years, the ratio, by the classification of actual productive age, was statistically higheron Monday. In addition, the ratio showed statistically higherby educational background, from elementary school to high school and over high school. In regard tothe medical aspect, incidence of cerebral hemorrhage showed higher ratio on Sunday, and incidence of brain infarction was higheron Monday. However, there was no difference of the past history between the two groups. With regard tothe aspect of lifestyle of subjects, the group with huge stress before the incidence of stroke showed a higher ratio of stroke incidence on Monday. Participants who didn't exercise regularly and participants who didn't smoke or drink showed higher ratio of stroke incidence on Monday. However, this was not important statistically. In regard to the aspect of Sasang constitution, Soeumin showed the highest ratio of stroke incidence on Wednesday, Taeuminon Monday, and Soyangin on Saturday and Monday. Conclusion : According to these results, several cardiovascular risk factors affect stroke incidences on Monday. Further studies will be needed to help understand the correlation between stroke incidence by day of the week and risk factors in acute stroke patients.
