The purpose of this study has been to describe the microanatomy of the recurrent artery of Heubner (RAH) in detail, to deepen anatomical knowledge and aid neurosurgeons in their work. The material was obtained from cadavers (ages 31-75 years) at routine autopsy. A total of 70 human brains (39 male and 31 female) were examined. People who died due to neurological disorders were not included in the study. Right after dissection, the arteries were perfused with acrylic paint emulsion, through the Circle of Willis or electively through the RAH. Brains were fixed in a 10% solution of formaldehyde, sectioned and placed in methyl salicylate for tissue transparency. To obtain corrosion-casts, the vessels were perfused with polyvinyl chloride or Mercox CL-2R resin and corroded using concentrated potassium chloride. The obtained material was analyzed using a stereoscopic light microscope. The RAH was present in 138 hemispheres with a mean of 1.99 RAH per hemisphere (275 RAH in total). The mean RAH length was 25.2 mm and the mean RAH diameter, in its place of origin, was 1 mm. Two to 30 branches (mean=9.4) originated from the stem of the RAH. The number of RAHs showed a negative correlation to the number of arteries from the medial group of lenticulo-striate arteries (LSA) (R=-0.62; p < 0.0001) which branch off the middle cerebral artery (MCA). This study further supports the RAH embryologic theory by Abbie. The RAH, in its extra- and intracerebral course, may join with the middle group of the LSA or directly with the MCA.
本研究旨在详细描述 Heubner 回返动脉（RAH）的显微解剖结构，以加深解剖学知识，并为神经外科医生的工作提供帮助。研究材料来自常规尸检的尸体（年龄 31-75 岁）。共检查了 70 个人脑（39 名男性和 31 名女性）。本研究未包括因神经疾病而死亡的人。解剖后，立即通过 Willis 环或选择性地通过 RAH 将丙烯酸颜料乳液灌注到动脉中。将大脑固定在 10%甲醛溶液中，切片并放入水杨酸甲酯中以实现组织透明。为了获得腐蚀铸件，通过聚氯乙烯或 Mercox CL-2R 树脂对血管进行灌注，并使用浓氯化钾进行腐蚀。使用立体光学显微镜对获得的材料进行分析。138 个半球中有 RAH，平均每个半球有 1.99 条 RAH（共 275 条 RAH）。RAH 的平均长度为 25.2mm，起源处的平均 RAH 直径为 1mm。RAH 的干上有 2-30 个分支（平均 9.4 个）。RAH 的数量与发自大脑中动脉（MCA）的内侧纹状体动脉（LSA）组的动脉数量呈负相关（R=-0.62；p<0.0001）。本研究进一步支持了 Abbie 的 RAH 胚胎学理论。RAH 在其颅内和颅外的行程中，可能与 LSA 的中间组结合，或直接与 MCA 结合。
