手部静脉分布的规律

目的从临床应用解剖学角度，分析手部静脉分布的规律性。方法将６例前臂离断的新鲜上肢，以过氯乙烯乙酸乙酯溶液为填充剂，制成动、静脉分色铸型腐蚀标本。结果手部深静脉与相关动脉有伴行关系，但多数静脉的管径细小。手部浅静脉无伴行动脉，掌侧静脉管径细小，行程分散；背侧静脉管径粗大，行程规律性强。结论手部深静脉除掌深静脉弓和掌心静脉可供外科作吻合外，其它静脉不具备吻合条件。手掌侧浅静脉网无临床吻合价值，手背侧浅静脉是外科吻合的主要血管

The venative pattern of hands

Objective With the view of clinical applied anatomy, the distribution patterns of the veins of the hand were analyzed. Methods Erosive casts of different colors in arteries and veins of the hand were made by filling material of chlorinated polyvinyl chloride solution in ethyl acetate into six freshly amputated forearms. Results The venae profundae, the majority of which had small calibers, always accompanied the relevant arteries. The venae superficialis didn't accompany any named arteries. The veins at the palmar aspect had small calibers and coursed irregularly. The veins at the dorsal aspect had large calibers and regular patterns of their courses. Conclusions The venae profundae in the hand has no value in surgical anastomosis, except the arcus palmaris profundus and venae metacarpeae palmares. Rete venosum dorsale manus is often used for surgical anastomosis, while rete venosum palmar manus has no clinical value for anastomosis.
