68세된 남자로 좌측과 후측 흉부에 통증을 주소로 내원하였다. 술전 시행한 흉복부 W scan에서 대동맥류는 좌측 쇄골하동맥에서 횡격막까지 연결되었고 긴박성 파열의 소견도 보였다. 또한 술전 관동맥조영술에서는 좌회선동맥에 95%, 좌전하행지에 50%의 협착소견을 보였다. 수술은 고동맥-고정맥 우회술을 하면서 좌측 제 4늑간을 통하여 측후방 개흉절개를 하여 수술시야를 확보하였고 대동맥을 차단한뒤 대동맥류를 절개하고 인조혈관으로 대치하였다. 그리고 심박동하에서 대복제정 맥을 이용하여 좌회선동맥의 두번째 둔각변연동맥과 좌측 쇄골하동맥 기시부에 관상동맥 우회술을 하였다. 술후 환자는 술중 저혈압성 쇼크와 저산소증으로 다발성 뇌경색의 합병증을 보였다.

Objectives: The authors tried to analyze the results of carotid artery sacrifice with or without preoperative carotid evaluation. Materials and Methods: Thirteen patients undergone carotid sacrifice were evaluated. Carotid balloon occlusion test (BOT) and single-photon emission computed tomography (SPECT) with technetium-99m-labeled hexamethylpropyleneamineoxime ($^{99m}Tc-HMPAO$) were used for preoperative carotid evaluation. Results: The causes of carotid artery sacrifice consisted of the neck mass involving the carotid artery, spontaneous aneurysmal rupture, and traumatic pseudoaneurysm. Five patient had postoperative neurologic complications and two of them had permanent neurologic deficits. Conclusion: The authors stress that the preoperative evaluation in carotid artery sacrifice is imperable, and the BOT with SPECT can be used in selecting the method of treatment. But since these tests cannot predict the postoperative outcome perfectly, careful perioperative care of the patients should be exercised regardless of the results of the preoperative evaluation.

Objective : The purpose of this study was to investigate the prognostic factors in patients who suffered an intracerebral hemorrhage(ICH) due to a ruptured middle cerebral artery(MCA) aneurysm. Methods : Among 148 case of ruptured MCA aneurysm, ruptured MCA aneurysm with ICH was compared with ruptured MCA aneurysm alone. According to factors, the prognosis in these two groups was analyzed. Prognosis was evaluated postoperatively by applying Glasgow Outcome Scale(GOS) at discharge. Prognostic factors were evaluated with Chi square test, Mann-Whitney test and ANOVA test with differences being considered significant for value less than 0.05. Results : Ruptured MCA aneurysm alone revealed better consciousness on admission and final outcome than those combined with ICH. Ruptured MCA aneurysm alone showed 74% in H-H grade I, II and 82% in GOS I, II. But ruptured MCA aneurysm with ICH showed 63% in H-H grade IV, V and 52% in GOS IV, V. Age, sex, lesion site, aneurysmal size, temoporary clipping time, interval to operation, operative approach were statistically not significant in prognosis(p>0.05). But H-H grade on admission(p<0.05), complication(esp. cerebral infarction)(p<0.05), preoperative ICH volume and site(p<0.01), preoperative midline shifting(p<0.01), remained ICH volume(p<0.05) showed significance statistically. Conclusion : Prognostic factors are helpful to neurosurgeon to estimate clinical and neurological outcome postoperatively. We suggest that the good prognostic factors in ruptured MCA aneurysm with ICH were good H-H grade on admission, cerebral infarction(-), preoperative ICH volume <25cc, temporal and intrasylvian ICH, preoperative midline shifting <5mm, remained ICH volume <10cc.

Objective: Delayed ischemic deficit or cerebral infarction is the leading cause of morbidity and mortality after aneurysmal subarachnoid hemorrhage (SAH). The purpose of this study is to reassess the prognostic impact of intraoperative elements, including factors related to surgery and anesthesia, on the development of cerebral infarction in patients with ruptured cerebral aneurysms. Methods: Variables related to surgery and anesthesia as well as predetermined factors were all evaluated via a retrospective study on 398 consecutive patients who underwent early microsurgery for ruptured cerebral aneurysms in the last 7 years. Patients were dichotomized as following; good clinical grade (Hunt-Hess grade I to III) and poor clinical grade (IV and V). The end-point events were cerebral infarctions and the clinical outcomes were measured at postoperative 6 months. Results: The occurrence of cerebral infarction was eminent when there was an intraoperative rupture, prolonged temporary clipping and retraction time, intraoperative hypotension, or decreased $O_2$ saturation, but there was no statistical significance between the two different clinical groups. Besides the Fisher Grade, multiple logistic regression analyses showed that temporary clipping time, hypotension, and low $O_2$ saturation had odds ratios of 1.574, 3.016, and 1.528, respectively. Cerebral infarction and outcome had a meaningful correlation (${\gamma}$=0.147, p=0.038). Conclusion: This study results indicate that early surgery for poor grade SAH patients carries a significant risk of ongoing ischemic complication due to the brain's vulnerability or accompanying cardio-pulmonary dysfunction. Thus, these patients should be approached very cautiously to overcome any anticipated intraoperative threat by concerted efforts with neuro-anesthesiologist in point to point manner.

Objective : In this study, the Mindfulness Based Stress Reduction (MBSR) program was applied to patients presenting with depression and anxiety after surgery from spontaneous subarachnoid hemorrhage (SAH) and the effects were assessed. Methods : The subjects were patients admitted for cerebral aneurysm rupture and treated by means of surgery from March to December, 2007. More than 6 months had passed after surgery, without any special lesions showing up on computed tomography (CT), and the Glasgow outcome scale (GOS) was 5 points. Among patients with anxiety and depression symptoms, 11 patients completed the program. The MBSR program was conducted once a week, 2.5 hours each, for 8 weeks. The evaluation criteria were : 1) the Beck Depression Inventory (BDI): it measures the type and level of depression, 2) the State-Trait Anxiety Inventory : the anxiety state of normal adults without mental disorder, and 3) Heart Rate Variability (HRV) : the influence of the autonomous nervous system on the sinoarterial node varies continuously in response to the change of the internal/external environment. Results : The BDI value was decreased from 18.5 ${\pm}$ 10.9 to 9.5 ${\pm}$ 7.1 (p = 0.013) : it was statistically significant, and the depression level of patients was lowered. The state anxiety was decreased from 51.3 ${\pm}$ 13.9 to 42.3 ${\pm}$ 15.2; the trait anxiety was reduced from 50.9 ${\pm}$ 12.3 to 41.3 ${\pm}$ 12.8, and a borderline significant difference was shown (p = 0.091, p = 0.056). In other words, after the treatment, although it was not statistically significant, a decreased tendency in anxiety was shown. In the HRV measurement, standard deviation normal to normal (SDNN), square root of the square root of the mean sum of squared differences between adjacent normal to normal intervals (RMSSD), and total power (TP) showed significant increase, Physical Stress Index (PSI) showed a significant reduction, and thus an improvement in the homeostatic control mechanism of the autonomic nervous system was ween. Conclusion : The MBSR program was applied to the patients showing anxiety and depression reaction after SAH treatment, and a reduction in depression symptoms and physiological reactions were observed. The application of the MBSR program may be considered as a new tool in improving the quality of life for patients after surgery.

결핵성 대동맥염은 그 빈도가 드문 질환이다. 이 결핵성 대동맥염으로 인한 합병증인 동맥류의 발생이나 대동맥-기관지루의 형성은 더욱 희귀하며, 만일 대동맥의 파열이 동반된다면 그 사망률은 치명적으로 매우 높다. 객혈을 주소로 내원한 환자가 있다면, 결핵의 병력이 없더라도 즉시 흉부 컴퓨터 단층촬영을 시행해야 신속하고 정확하게 이 질환을 진단할 수 있다. 환자는 46세 남자로, 내원 하루 전부터 시작된 객혈과 흉부 불편감을 주소로 내원하였다. 시행한 흉부 컴퓨터 단층촬영상 하행성 흉부 대동맥의 동맥류 소견이 관찰되었으며, 대동맥-기관지루를 통해 좌측 폐하엽과 연결되어 있었다. 본원에서는 하행성 흉부 대동맥의 인조혈관 치환술 및 좌측폐하엽 절제술을 시행함으로써 좋은 결과를 얻을 수 있었다. 조직학적 검사 결과 결핵으로 확진되어 항결핵제 치료를 시작하였으며, 향후 장기간의 항결핵제 복용이 추천된다.

목 적 : 원위부 전대뇌 동맥에 발생하는 동맥류는 모동맥의 확보가 힘들고 재출혈 및 수술중 조기출혈의 빈도가 높으며, 익숙치 않은 수술적 접근법이 필요하다든지 하는 몇 가지 독특한 문제점이 있다. 따라서 전대뇌 반구간열 주변의 해부학적 구조물과 박리 시작점에 대한 수술전 지식을 요한다. 저자들은 박리 시작점에 대한 일관된 외부표식자를 이용하여 전두 기저부 대뇌반구간열 접근법 수술을 시행하였고 이를 심부 구조물들에 대한 접근 지표로 삼고자 하였다. 대상 및 방법 : 1995년 11월부터 1999년 6월까지 동맥류경을 결찰한 총 131명의 뇌동맥류파열 환자 중에서 원위부 전대뇌 동맥류 9명에 대하여 혈관조영술, 의무기록지, 수술소견을 통해 임상적, 수술소견을 조사하였다. 결 과 : 원위부 전대뇌동맥류의 빈도는 6.3%였고, 6례에서 뇌량 연변 동맥이 기시하는 뇌량 주위 동맥에서 발생하였고, 3례에서는 전두극동맥이 기시하는 뇌량 주위 동맥에서 발생하였다. 동반된 다른 혈관기형 및 다른 동맥류는 각각 3예에서 발견되었다. 술전 환자 상태는 일반적으로 불량했다. 조기수술은 7예에서 실시되었으며, 전두 기저부 대뇌반구간열 접근법으로 동맥류 결찰을 시행한 경우도 7예였다. 술후 심한 혈관연축과 흡인성 폐렴으로 인한 사망이 각각 1례씩이었으며 그 이외에는 신경학적 소견은 정상이었다. 결 론 : 원위부 전대뇌 동맥류의 조기수술시에 전두 기저부 대뇌반구간열 접근법이 유용하였다. 이 방법으로 뇌견인을 최소화할 수 있었으며 동맥류의 조기파열을 방지할 수 있었다. 저자들은 대뇌반구 간열의 박리 시작점으로 첫번째 교정맥(전두극 정맥)이 상시상 정맥동으로 유출되는 지점을 기준으로 하여 뇌량 및 뇌량 주변부 원위부 전대뇌동맥류에 접근할 수 있었다.
