Abstract

Purpose: The incidence of early branches arising from the prebifurcation trunk of the middle cerebral artery is very high. However, no reports have addressed these early branches of middle cerebral arteries in the Korean population. The purpose of this study was to characterize these early branches in Koreans. Materials and Methods: A retrospective review was performed on transfemoral cerebral angiograms performed at Jeju National University Hospital between May 2005 and March 2010. A total of 78 hemispheric angiogram sites met the study inclusion criteria. The digital subtraction anterior-posterior view was the basic image for the inspection, which was supplemented by a three-dimensional reconstructed image. Results: We identified 86 early branches of the middle cerebral artery in 58 (74.4%) out of 78 hemisphere angiogram sites. The type of early branches in the 78 hemispheric angiograms included 20 angiograms that were classified as Group I (25.6%), 23 as Group II A (29.5%), 10 as Group II B (12.8%), 7 as Group II C (9.0%), 7 as Group III (9.0%), and 11 as Group IV (14.1%). Conclusion: The incidence of early branches arising from the prebifurcation trunk of the middle cerebral artery was found to be high in the Korean population and showed many morphological variations.

목적: 중대뇌동맥에서 기원하는 조기분지는 매우 발현빈도가 높음에도, 한국인을 대상으로 하여 조기분지의 형태를 규명한 연구가 아직 없기에 본 연구를 시행하였다. 대상과 방법: 2005년 5월부터 2010년 3월까지 제주대학교병원에서 고식적 방법의 뇌혈관조영술을 시행 받은 78건의 성인 환자 뇌혈관조영상을 분석하였다. 디지털감산혈관조영술(digital subtraction angiography)의 전 후면 영상을 기본으로 하고 3차원 입체영상으로 보완하며 조기분지의 형태를 관찰하였다. 결과: 58건의 뇌혈관조영상에서 모두 86개의 조기분지를 발견하였고, 조기분지의 발현빈도는 78건중 58건으로 74.4%이었다. 78건의 조기분지의 형태는 Group I 20건(25.6%), Group II A 23건(29.5%), Group II B 10건(12.8%), Group II C 7건(9.0%), Group III 7건(9.0%), Group IV 11건(14.1%)이었다. 결론: 한국인의 중대뇌동맥 조기분지의 발현빈도가 높았으며, 조기분지의 형태는 매우 다양하였다.
