In 1993 Angrigiani raised the question as to whether the distal part of the posterior interosseous artery (AIP) is a recurrent branch of the anterior interosseous artery (AIA) and forms a "choke"--anastomosis with the AIP in the middle of the forearm. A dissection study was conducted on 66 upper extremities to evaluate the diameters of the dorsal branch of the anterior interosseous artery, the anastomotic branch, the diameter of the posterior interosseous artery at the point of origin of the septocutaneous perforators in the middle of the forearm and the diameter of the posterior interosseous artery at the point of emergence in the dorsal compartment. We further tried to identify different forms and types of the "distal" anastomosis and the connections to the dorsal carpal arch and the ulnar artery. A distal anastomosis between the AIA and AIP was found in 65 of the 66 upper extremities. Three different types of anastomosis could be identified. The smallest diameter was found at the middle of the forearm (mean diameter AIA 1.28 mm; anastomotic branch 0.6 mm; AIP at the middle of the forearm 0.39 mm; AIP prox. 1.35 mm). A branch through the fifth extensor compartment was present in all of our specimens (mean diameter 0.54 mm). A branch through the forth extensor compartment could be found in 16 specimens. Based on our findings and the embryological development, we conclude that the AIP is only present in the proximal half of the forearm. In the distal part, the dorsal branch of the anterior interosseous artery forms a vascular arcade, which gives off branches to the dorsal carpal arch, the ulnar head and the ulnar artery. This arcade anastomoses with the posterior interosseous artery in the middle of the forearm by means of a choke anastomosis. We also conclude that the term "recurrent branch of the anterior interosseous artery" for the distal part of posterior interosseous artery is correct.
1993年，安格里贾尼提出了一个问题，即骨间后动脉（AIP）的远端部分是否是骨间前动脉（AIA）的返支，并在前臂中部与骨间后动脉形成“扼流”吻合。对66个上肢进行了解剖研究，以评估骨间前动脉背侧支、吻合支的直径，前臂中部皮穿支起点处的骨间后动脉直径以及骨间后动脉在背侧间隙穿出点处的直径。我们进一步试图确定“远端”吻合的不同形式和类型以及与腕背弓和尺动脉的连接。在66个上肢中的65个中发现了骨间前动脉和骨间后动脉之间的远端吻合。可以识别出三种不同类型的吻合。在前臂中部发现的直径最小（骨间前动脉平均直径1.28mm；吻合支0.6mm；前臂中部的骨间后动脉0.39mm；骨间后动脉近端1.35mm）。我们所有标本中均存在一条穿过第五伸肌间隙的分支（平均直径0.54mm）。在16个标本中可以发现一条穿过第四伸肌间隙的分支。基于我们的发现和胚胎发育，我们得出结论，骨间后动脉仅存在于前臂的近端一半。在远端，骨间前动脉的背侧支形成一个血管弓，该血管弓向腕背弓、尺骨头和尺动脉发出分支。这个血管弓通过扼流吻合在前臂中部与骨间后动脉吻合。我们还得出结论，将骨间后动脉远端部分称为“骨间前动脉返支”是正确的。
