  • 배경: 뇌혈관계 합병증은 관상동백우회술 후 발생하는 사망률 중 10% 이상을 차지하는 치명적인 질환이다. 최근들어 고령 환자, 고혈압, 당뇨병 등이 병발하고 고 위험군에 대한 수술이 증가하면서 뇌혈관계 합병증은 오히려 증가하고 있다. 본 연구는 관상동맥우회술을 받은 환자의 의무기록을 조사하여 관상동맥우회술 후 발생되는 뇌혈관계 질환의 위험 인자를 밝히고자 한다. 대상 및 방법: 1991년 3월부터 1999년 7월 사이에 관상동맥우회술을 받은 185명을 조사하여, 뇌혈관계 합병증의 위험 인자들을 통계적으로 검증하였다. 결과: 뇌혈관계 합병증의 유병율은 7.57%(14명)였으며 이중 5예는 사망하였다. 동 기간 중 전체 사망은 11예이므로 사망자의 45.5%가 뇌혈관계 합병증으로 사망한 것이다. 통계적의의가 있는 뇌혈관계 합병증 위험 인자로는 수술 후 부정맥(p=0.0064), 기왕의 뇌혈관계 병력(p=0.0090), 체외순환시간(p=0.0181), 대동맥의 동맥경화(p=0.03575) 및 당뇨병(p=0.0452) 등이었다. 경동맥협착이 동반되어 경동맥 혈관내막 절제술(carotid endarterectomy)을 동시에 시술한 경우는 2예였으나, 뇌혈관계 합병증은 발생하지 않았다. 75세 이상의 고령환자는 3명이었으며 모두 뇌혈관계 합병증은 발생하지 않았다. 결론: 관상동맥우회술 후 발생하는 뇌혈관계 질환과 통계적으로 유의한 위험요인은 수술 후 부정맥, 뇌혈관이상의 기왕력, 체외순환시간, 대동맥궁의 동맥경화, 당뇨 등이었다.

  • Rupture of an innominate artery caused by blunt chest trauma is extremel rare because this artery is short and relatively well protected by the bony cage. This report describes a 37-year-old male who sustained a blunt chest injury that resulted in an innominate artery rupture, detected by chest CT and thoracic aortography. The patient underwent an urgent operation through median sternotomy. A 3 by 3 m sized pseudoaneurysm of proximal innominate artery was found with a complete intimal tear. After the origin of the innominate artery was closed, the injured segment of artery was excised and an aorto-innominate artery bypass with a 10 mm Gore-tex graft was performed without use of a shunt. The patient was discharged 20 days later without neurologic complications and had equal blood pressure in both arms.

  • From October 1990 to May 1993, 19 patients underwent replacement of the transverse aortic arch. [10 men, 9 women, mean age 52.5 years] Underlying diseases were acute aortic dissection [10 cases], chronic aortic dissection [4 cases],and aortic arch aneurysm [ 5 cases]. In 19 patients, 10 underwent partial replacement and 9 underwent total arch replacement. The cerebral protection was achieved by profound hypothermia [rectal temperature,16$^{\circ}$ to 2$0^{\circ}C$] associated with total circulatory arrest [mean 35.5 minutes]. In one patient, the aortic arch distal to the left common carotid artery was resected with the distal arch being cross-clamped and in another two patients, the selective cerebral perfusion was also applied during the period of total circulatory arrest via innominate artery and left common carotid artery because of longer total circulatory arrest time. Among 14 patients of aortic dissecton, 10 presented hypertension, 1 presented Marfan syndrome, 1 presented pregnancy-induced hypertension and 2 revealed no evidence of hypertension. All of the above 14 patients complained chest pain. Among 5 patients of aortic arch aneurysm, Be het disease was suspected in only one patient and atherosclerotic aneurysm was proved in another 4 patients. The overall hospital mortality was 32% [6/19]. In aortic dissection, the mortality was 43% [Acute aortic dissection 30%, chronic aortic dissection 75%] and in aortic arch aneurysm, the mortality was 0%. Follow-up was done in all survivors for from 7 months to 36 months[mean,17.3%].
