It is crucial to know the lengths of the neurovasculature proximal to a penile allograft to allow for better viability of a penile transplant. We performed a cadaveric exploration focused on the deep and superficial dorsal veins as identified in a microsurgical dissection of the penis to help expand the anatomical knowledge for such a procedure.
We examined 18 cadavers and measured the (1) vertical distance from the pubic symphysis to the point at which the superficial dorsal vein is no longer on the erectile tissue; (2) point at which the superficial dorsal vein is no longer on the erectile tissue to where its tributary meets the great saphenous vein; and (3) point at which the deep dorsal vein is no longer on the external erectile tissue to its contribution into the prostatic plexus near the prostate. Moreover, we noted the variations of the deep and superficial veins of the penis. We used IBM SPSS in all statistical analyses.
The average length of the superficial dorsal vein when no longer on the external penis to its tributary was 84.9 ± 10.4 mm. The average length of the deep dorsal vein was 72.9 ± 6.43 mm. Three different drain patterns were observed for the superficial dorsal vein, whereas the deep dorsal vein was consistently midline. No statistically significant correlations were identified between cadaveric demographic data and lengths of venous structures.
Further studies regarding the anatomy and dissection of penile allografts would be helpful. More research regarding donor and recipient anatomy and vasculature is needed to establish surgical guidelines.
了解阴茎同种异体移植近端神经血管的长度对于提高阴茎移植的存活率至关重要。我们进行了尸体解剖研究，重点关注阴茎显微外科解剖中所确定的阴茎深背静脉和浅背静脉，以拓展此类手术的解剖学知识。
我们检查了18具尸体，并测量了：（1）从耻骨联合到浅背静脉不再位于勃起组织上的点的垂直距离；（2）浅背静脉不再位于勃起组织上的点到其分支与大隐静脉汇合处的点；（3）深背静脉不再位于阴茎外部勃起组织上的点到其在前列腺附近汇入前列腺丛的点。此外，我们还记录了阴茎深静脉和浅静脉的变异情况。所有统计分析均使用IBM SPSS软件。
浅背静脉从不再位于阴茎外部到其分支的平均长度为84.9±10.4毫米。深背静脉的平均长度为72.9±6.43毫米。浅背静脉观察到三种不同的引流模式，而深背静脉始终位于中线。尸体的人口统计学数据与静脉结构长度之间未发现统计学上的显著相关性。
关于阴茎同种异体移植的解剖学和解剖方法的进一步研究将有所帮助。需要更多关于供体和受体解剖学及血管系统的研究来制定手术指南。
