The abdominal and pelvic blood supply of the Mediterranean pine vole (Microtus duodecimcostatus) is described. A total of 13 individuals (seven males, six females) captured in the field (Sanaüja, Spain) were analysed by injection of coloured latex solution and subsequent dissection. The arrangements observed in all specimens show some common traits in relation to the patterns established in other Arvicolidae studied (Arvicola terrestris, Clethrionomys glareolus, Microtus H agrestis). These shared characteristics are centered on the origin of the deep circumflex iliac and the medial femoral circumflex arteries. As a particular variation from other Arvicolidae, some specimens of M. duodecimcostatus exhibit a gastrolienal trunk in the coeliac axis. Furthermore, the origin of the prostatic or the vaginal artery from the pudendoepigastric trunk observed in some specimens of M. duodecimcostatus has not previously been reported in other myomorph rodents.
本文描述了地中海松田鼠（Microtus duodecimcostatus）的腹部和盆腔血液供应情况。通过向13只（7只雄性，6只雌性）在野外捕获（西班牙萨纳乌哈）的个体注射彩色乳胶溶液并随后进行解剖分析。在所有标本中观察到的血管分布与其他已研究的田鼠科动物（水䶄（Arvicola terrestris）、林姬鼠（Clethrionomys glareolus）、普通田鼠（Microtus agrestis））所确立的模式有一些共同特征。这些共同特征集中在旋髂深动脉和股内侧旋动脉的起源上。作为与其他田鼠科动物的一个特殊差异，一些十二肋松田鼠标本在腹腔干中有胃脾干。此外，在一些十二肋松田鼠标本中观察到的前列腺动脉或阴道动脉起源于阴部腹壁干的情况，此前在其他鼠形啮齿动物中尚未有过报道。
