【摘要】 作者观测了47具成年男尸的小隐静脉94例。结果表明:小隐静脉起始可分为五型,且第Ⅰ型稍多(33.0％);多数静脉行于小腿后正中线外侧,其中于股骨髁间线以下穿入深筋膜者占58.3％,位于腓肠神经内侧者占57.5％;按汇入部位可分为三型,并以正常型为多见(71.3％)。每例瓣膜数为3～14个,99.3％为双叶瓣。与浅深静脉间的交通支大多数分布于小腿中1/3段。更多还原

【Abstract】 The small saphenous vein (SSV) wereinvestigated on both sides of 47 Chinese malecadavers.The chief results are as follows. 1. The origins of SSV are classified into5 types. Type Ⅰ (33.0%) and type Ⅱ (22.3%)are commonly seen, and the last vein thelateral border of the foot (78.7%) and lateralextremity of the dorsal venous arch (54.3%)are the most common participators to theformation of SSV. 2. Ninty-nine-percent of SSV ascendlateral to the posterior midline of the calf inthe lower 1/3 of the leg and about half ofthem maintain their lateral position in theupper 2/3. More than half (57.5%) of SSVrun medially to the course of sural nerve.More than 58% of the SSV pierce into thedeep fascia below the intercondylar line ofthe femur. 3. The destinations of SSV fall into 3catagories. TypeⅠ (71.3%) empties into thepopliteal vein in the popliteal fossa;type Ⅱ(26.6%) joins the femoral vein directly orindirectly above the popliteal fossa;type Ⅲ(2.1%) empties into the great saphenousvein somewhere in the leg. 4. The numbers of valve in each SSVvary from 3 to 14 (average 6.6± 1.1).Theyare approximately equally distributed alongthe whole length of the vein; 99.3% of thevalves are bifoliate of hyperbolic type withtheir slits run parallel with the skin. 5. The communicating branches of SSVwith great saphenous vein and with the deepvein of the leg are confined in the middle1/3 of the leg, 58.0% and 50.8% respective-ly. The surgical significance of the resultsare discussed.更多还原
