Abstract
결론
저자는 중대뇌동맥 분지부 동맥류 환자의 뇌혈관조영술을 분석한 결과를 요약하였고 다음
과 같은 결론을 얻었다.
1) 중대뇌동맥류의 방향은 측방이 가장 많았다.
2) 동맥류측 중대뇌동맥 근위부의 길이는 반대측 근위부의 길이와 차이를 보이지 않았다.
3) 중대뇌동맥 분지부 동맥류가 발생하는 뇌혈관조영술 소견으로는 전대뇌동맥과 중대뇌동
맥간의 각도가 작고, 중대뇌동맥 상,하분지간의 각도가 큰 경우였다.
4) 통계학적 유의성은 없었으나 중대뇌동맥 근위부와 상분지간의 평균 각도가 클수록 중대
뇌동맥 분지부 동맥류는 하방을 향하는 경향을 보였다.
이상의 결과를 종합해 보면 중대뇌동맥 분지부 동맥류는 혈류의 방향으로 호발하며 중대뇌
동맥 근위부의 길이는 동맥류 발생에 영향을 주지 않았다. 또한, 뇌혈관조영술을 통한 간접
적인 방법이기는 하나 중대뇌동맥 분지부 동맥류는 전대뇌동맥과 중대뇌동맥간에 각이 작고
중대뇌동맥 상,하분지간의 각도가 큰 경우에 호발할 것으로 사료된다.

It is generally believed that the important factor in cerebral aneurysmal formation is
mural degeneration where sustained hemodynamic stress is maximal.
The authors have investigated angiographic findings to evaluate the relationship of
aneurysmal formation and anatomical characteristics. Between January 1994 and
December 1996, 386 patients with spontaneous subarachnoid haemorrage underwent
cerebral angiographic studies. Among these, 83 patients had middle cerebral artery
bifurcation aneurysm without intracerebral hematoma in computed tomography and
without vasospasm in angiography. These patients were compared with 68 patients with
subarachnoid haemorrage who showed normal angiographic finding.
Parameters for angiographic measuring were the direction of aneurysm, the length of
proximal middle cerebral artery, the ratio of diameter and angles between internal
carotid artery, anterior cerebral artery, middle cerebral artery, and superior and inferior
trunk of middle cerebral artery.
These data were analysed by student t-test, ANOVA, and the results were as follows
:
1) Fifty-two cases(63%) of middle cerebral artery bifurcation aneurysm directed
laterally.
2) The length of proximal middle cerebral artery was not significantly different from
that of control group.
3) Middle cerebral artery bifurcation aneurysms were frequently seen in angiography
when angle between anterior cerebral artery and middle cerebral artery was more
decreased and angle between superior and inferior trunk of middle cerebral artery was
more increased.
4) Middle cerebral artery bifurcation aneurysm revealed to be more inferiorly directed
when angle between proximal segment of middle cerebral artery and superior trunk of
middle cerebral artery was more increased.
