Basilar artery is formed by the fusion of right and left vertebral artery and terminates as right and left posterior cerebral arteries. The aim of the study is to observe the diameter of basilar artery at three different levels (at its formation, at its midlevel and at its termination). This cross sectional descriptive study was performed on total 60 postmortem human hindbrain to find out the variation of position and diameter of the basilar artery of Bangladeshi people in relation to age. The specimens were collected from morgue in the department of Forensic Medicine, Mymensingh medical College, Mymensingh, Bangladesh by purposive sampling technique. All the specimens were grouped into four categories: Group A (20 to 29 years), Group B (30 to 39 years), Group C (40 to 49 years) and Group D (50 to 59 years). Diameter of basilar artery was measured with the help of digital slide calipers at three different levels. At the level of its formation, mean±SD diameter was 3.76±0.37 mm, 3.75±0.32 mm, 3.68±0.24 mm & 3.54±0.46 mm in Group A, B, C & D respectively. At mid-level, it was 3.49±0.36 mm, 3.48±0.30 mm, 3.45±0.21 mm & 3.36±0.44 mm in Group A, B, C & D respectively. At the termination, it was 3.55±0.35 mm, 3.51±0.30 mm, 3.48±0.22 mm & 3.38±0.38 mm in Group A, B, C & D respectively. This knowledge of variations of the diameter of basilar artery is of diagnostic importance for the neurosurgeons and radiologists for clinical investigation and surgery.
基底动脉由左右椎动脉汇合而成，终止于左右大脑后动脉。本研究的目的是观察基底动脉在三个不同水平（形成处、中间水平和终止处）的直径。这项横断面描述性研究对总共60例人类后脑尸体进行，以找出孟加拉国人基底动脉位置和直径随年龄的变化。标本通过目的抽样技术从孟加拉国迈门辛医学院法医学系停尸房收集。所有标本分为四类：A组（20至29岁）、B组（30至39岁）、C组（40至49岁）和D组（50至59岁）。借助数字游标卡尺在三个不同水平测量基底动脉直径。在其形成水平，A组、B组、C组和D组的平均±标准差直径分别为3.76±0.37毫米、3.75±0.32毫米、3.68±0.24毫米和3.54±0.46毫米。在中间水平，A组、B组、C组和D组分别为3.49±0.36毫米、3.48±0.30毫米、3.45±0.21毫米和3.36±0.44毫米。在终止处，A组、B组、C组和D组分别为3.55±0.35毫米、3.51±0.30毫米、3.48±0.22毫米和3.38±0.38毫米。基底动脉直径变化的这一知识对神经外科医生和放射科医生进行临床研究和手术具有诊断重要性。
