摘要
用巨微解剖法观测50侧成人膝区。结果显示:半月板血供来自腘动脉关节支和膝降动脉降支。膝上外侧动脉不参与半月板的血供,但发现腘动脉另有一对关节支恒定地供应半月板后部,可命名为膝后内、外侧动脉。供应半月板的动脉,绕半月板形成一板周动脉环。环发支分支于半月板,并形成股、腘动脉之间的侧副吻合。
Fifty adult lower limbs were studied macromicroscopically to reveal the extrinsic blood vessels of the menisci of the knee joint. It was found that the menisci were supplied from 2 sources, the genicular branches (except the superior lateral genicular branch) of the popliteal artery, and the descending branch of the descending genicular artery. A pair of additional genicular branches with independent stems from the popliteal artery, named as the posterior medial and the posterior lateral genicular arteries by the authors, constantly supplied the posterior part of both the menisci. The arterial branches formed a circular anastomotic arch around the menisci with small branches springing from the arch and getting into the menisci. The arterial arch communicated with the femoral and the popliteal arteries and became an important stem of a reentry channol in cases of popliteal artery occlusion.
