The arterial supply of the acetabulum is studied in 30 human hip-pelvis specimens utilizing conventional angiography, 3 D-CT and maceration. 3 specimens out of 30 had to be excluded due to extravasation and incomplete filling. The arteries of the pelvis were filled with barium sulfate in 16 cases and in 11 cases with a solution of resin and lead powder. Conventional angiograms were performed in all specimens. In preparations with resin/lead powder additional CT with 3 D reconstructions of the surface of the acetabulum and arteries were done. 3 D-CTs show precise relationship of the arteries to the acetabulum. Filling with resin and lead powder is optimal for anatomical studies. It permits comparative 3 D-CT and conventional X-ray examination and subsequent preparation of the vessels in corrosion technique. The central parts of the acetabulum are vascularized by the obturator artery, the cranio-lateral part by the a. glutea superior and the ischial parts by the a. glutea inferior. The arterial supply of the acetabulum can be saved knowing the way and entry of the arteries into the bone. This is of importance for triple osteotomies of the pelvis but as well for difficult total hip replacements and revisions. The described method can be used for anatomical studies of the vessel to bone correlation in different anatomical sites.
利用传统血管造影、三维CT和浸蚀法对30例人体髋关节-骨盆标本的髋臼动脉供应进行了研究。30例标本中有3例因造影剂外渗和充盈不全而被排除。16例骨盆动脉用硫酸钡充盈，11例用树脂和铅粉溶液充盈。对所有标本均进行了传统血管造影。对于用树脂/铅粉处理的标本，还进行了髋臼和动脉表面三维重建的CT检查。三维CT显示了动脉与髋臼的精确关系。用树脂和铅粉充盈对解剖学研究最为理想。它允许进行三维CT和传统X线检查的对比，并随后采用腐蚀技术对血管进行标本制备。髋臼的中央部分由闭孔动脉供血，颅外侧部分由臀上动脉供血，坐骨部分由臀下动脉供血。了解动脉进入骨骼的途径和入口，髋臼的动脉供应得以保留。这对于骨盆三联截骨术很重要，对于困难的全髋关节置换和翻修手术也很重要。所描述的方法可用于不同解剖部位血管与骨骼相关性的解剖学研究。
