The recurrent artery of Heubner (RAH) is the largest vessel of the medial lenticulostriate arteries. It supplies many deep structures, mainly the corpus striatum, the globus pallidus, and the anterior crus of the internal capsule. The aim of the present paper was studying the morphological variations of the RAH and its diameter in relation to different areas of origin. The series contained the records from 183 formalin-fixed adult human brains. The calibrated digital images of the studied brains were evaluated and measured by Image J, which can calculate the number of pixels and convert them to metric measures. The RAH arose most often from the postcommunicating part of the anterior cerebral artery (47.81%). It originated from the precommunicating part of the anterior cerebral artery in 3.55% and at the level of the anterior communicating artery in 43.4% of cases. The RAH was missing in 5.19% and doubled in 6.28% of cases. The mean outer diameter of the RAH was 0.6 mm. The maximal measured diameter was 1.34 mm, and the minimal diameter was 0.19 mm. The awareness of the various anatomical and morphometric variations of the RAH is essential in planning the neurosurgical procedures to avoid unexpected neurological complications.
Heubner 回返动脉（RAH）是内侧纹状体动脉中最大的血管。它供应许多深部结构，主要是纹状体、苍白球和内囊的前肢。本文旨在研究 RAH 的形态变异及其与起源部位不同的直径关系。该系列包含了 183 例福尔马林固定成人脑的记录。通过 Image J 评估和测量研究脑的校准数字图像，它可以计算像素数量并将其转换为度量单位。RAH 最常起源于大脑前动脉的交通后部分（47.81%）。它起源于大脑前动脉的交通前部分的占 3.55%，在前交通动脉水平的占 43.4%。RAH 缺失的占 5.19%，双份的占 6.28%。RAH 的外径平均值为 0.6 毫米。最大测量直径为 1.34 毫米，最小直径为 0.19 毫米。了解 RAH 的各种解剖和形态变异对于规划神经外科手术至关重要，以避免意外的神经并发症。
