The microvascular anatomy of Heubner's recurrent artery (RAH) was studied in 50 human brains (100 hemispheres) using acrylic paint under the operative microscope. The recurrent artery of Heubner was always found as a single vessel in 28 cases (28%) and multiple vessels in 72% (double vessels in 48%, triple in 23% and quadruple in 1%). Altogether 197 RAH were found in 100 hemispheres, averaging 1.97 arteries per hemisphere. In 44 instances, it originated from the proximal part of the A1-segment of the anterior cerebral artery. The diameters of the RAH ranged from 0.4 to 1.5 mm. Their vascular territory was variable. Four groups of distributing branches were found in the RAH: frontal and hypothalamic, olfactory, perforating and sylvian-fissure branches. In 12 hemispheres, anastomoses were found between the perforating branches of the RAH and the middle cerebral artery. In five cases (5%) anastomoses were present between the perforating branches of the MCA and the olfactory branch of the RAH. In one case (1%), an anastomosis was found between two RAH.
在手术显微镜下，使用丙烯酸颜料对50例人脑（100个半球）的Heubner回返动脉（RAH）的微血管解剖结构进行了研究。在28例（28%）中，Heubner回返动脉始终为单支血管，72%为多支血管（双支血管占48%，三支血管占23%，四支血管占1%）。在100个半球中共发现197支RAH，每个半球平均有1.97支动脉。在44例中，它起源于大脑前动脉A1段的近端。RAH的直径范围为0.4至1.5毫米。它们的血管分布区域各不相同。在RAH中发现了四组分布分支：额叶和下丘脑分支、嗅觉分支、穿支和外侧裂分支。在12个半球中，发现RAH的穿支与大脑中动脉之间存在吻合。在5例（5%）中，大脑中动脉的穿支与RAH的嗅觉分支之间存在吻合。在1例（1%）中，发现两支RAH之间存在吻合。
