本研究旨在对与乳腺前哨淋巴结对应的Ib级淋巴结的动脉供应进行详细的解剖学检查。这是通过使用41具尸体（49腋）的腋动脉干的路线变化的关系为重点。腋动脉的走行模式分为：“标准型”，穿入臂丛（发生率，51%）;“浅肱动脉型”，沿着臂丛浅层走行（2%）;“肩胛下浅动脉（SSbsA）型”，进入深层而不穿入臂丛（42.9%）;和其他（4.1%）。胸外侧动脉、胸背动脉、胸下动脉和胸浅动脉根据Ib淋巴结腋动脉的各走行类型以规则的成对关系分布。以SSbsA发生率为参照，比较Ib淋巴结的血供率，发现标准肩胛下动脉组的胸下动脉对照和SSbsA组的胸外侧动脉对照存在显著差异（p< 0.0001）。有人建议，在上肢发育过程中的血管网的选择性建模，两个形成趋势发生。当选择肱浅动脉系统中胸下动脉来源的供血动脉用于Ib淋巴结时，诱导标准腋动脉和SSbsA腋动脉干，或获取与SSbsA通路密切相关的胸外侧动脉来源的供血动脉。
This study aimed to conduct a detailed anatomical examination of the arterial supply to level Ib lymph nodes corresponding to mammary sentinel lymph nodes. This was achieved by focusing on the relationship with course changes of the axillary artery trunk using 41 cadavers (49 axillae). The course patterns of the axillary artery were classified as: “Standard type,” which penetrate the brachial plexus (occurrence rate, 51%); “Superficial brachial artery type,” which ran along the superficial layer of the brachial plexus (2%); “Superficial subscapular artery (SSbsA) type,” which entered the deep layer without penetrating the brachial plexus (42.9%); and others (4.1%). The lateral thoracic artery, thoracodorsal artery, inferior pectoral artery, and superficial thoracic artery were distributed in a regular pair relationship according to each running type of the axillary artery for the Ib lymph nodes. Comparing blood supply ratio to the Ib lymph nodes, using SSbsA occurrence as a reference, showed that significant differences were observed with the inferior pectoral artery control for the standard subscapular artery group and the lateral thoracic artery control for the SSbsA group (p< 0.0001). It was suggested that in selective modeling of vascular networks during upper limb developments, two formation tendencies occur. The standard axillary and SSbsA axillary artery trunks are induced when the inferior pectoral artery-derived feeding arteries in the superficial brachial artery system are selected for Ib lymph nodes, or lateral thoracic artery-derived feeding arteries, which are closely related to the SSbsA pathway, are acquired.
