摘要
目的：为吻合指掌侧浅静脉的断指再植术提供解剖学基础。方法：在１０个从桡动脉或尺动脉加压灌注美兰显示静脉的成人新鲜手标本上，解剖观察指掌侧浅静脉的形态、分布特点和管径。结果：①指掌侧浅静脉以１～３条小静脉起自指腹，从中节指远侧开始，形成２～３条可供吻合的纵向走行浅静脉，纵行静脉之间以及与指侧面的浅静脉有交通。指掌侧浅静脉在中线两侧走向指根部，在指蹼处邻指掌侧浅静脉汇合构成头间静脉，向背侧注入手背面的静脉，或注入手掌面远侧缘的边缘静脉弓。指掌侧浅静脉远侧指横纹处内径约０．３～０．６ｍｍ；中节指中部约０．４～０．７ｍｍ；近节指根部约０．６～１．０ｍｍ。②吻合指掌侧静脉的断指再植６８例９３指，成活８８指，成活率９４．６％。结论：吻合指掌侧浅静脉可完全解决再植指静脉回流问题。
The superficial palmar digital veins were anatomized in 10 adult hand specimens with methylene blue injection through the ulnaris or radialis artery.They originate from the veinlets of the finger belly running proximately to form 2～3 tiny superficial veins at the distal end of the middle segment of the finger.Connecting branches to the dorsal of the finger side were observed.The superficial palmar digital veins join together in wed and drain into the dorsal palmar veins or the marginal vein arch of the palm.The average diameters of the superficial palmar digital veins are 0.3～0.6 mm at the distal transversal stria.0.4～0.7 mm at the middle point of the midsegment of the finger and 0.6～1.0 mm at the root of the finger.In clinical practice,93 fingers of 68 patients were replanted with anastomosis of the superficial palmar digital veins,of which ,88 fingers were successfully replanted.These indicate that anastomosis of the superficial palmar digital veins is critical for the veinal drainage of replanted fingers.
