Background

Open surgical treatment of the pubic region and adductor related pathologies require an exact knowledge of the arterial blood supply of the symphysis pubis that seems furthermore important to explain the hematogenous occurrence of symphysitis. Pubic bone marrow oedema (PBME) is a frequent occurring magnetic resonance imaging finding in groin pain. However, even asymptomatic athletes present PBME and a correlation to the physical activity or higher blood flow was suggested. Data on the vascular anatomy of the symphysis pubis are rare.

Methods

Ten formaldehyde-embalmed cadavers were dissected, and the arterial blood supply was investigated and photographically documented.

Results

In the majority of cases the following pattern was determined: superior–inferior epigastric artery (n = 12 hemipelves), inferior - dorsal artery of the penis/dorsal artery of the clitoris (n = 16), posterior- obturator artery (n = 16 hemipelves), anterior- deep external pudendal artery (n = 14 hemipelves). Besides variations for the deep external pudendal artery anteriorly, we observed a highly variable arterial supply, especially superior. Superior in 4/10 cadavers, inferior in 0/10 cadavers, posterior in 2/10 cadavers and anterior in 5/10 cadavers side variations were found.

Conclusion

The symphysis pubis has a spatial and rich organized arterial blood supply with several variations. Despite the symphysis pubis is recognized as bradytroph, the high number of vessels is presumably required in stress situations for example in heavy training.

耻骨联合的动脉血供——空间定向且高度可变

背景

耻骨区和内收肌相关病变的开放手术治疗需要准确了解耻骨联合的动脉血供，这对于解释血行联合炎的发生似乎更重要。耻骨骨髓水肿 (PBME) 是腹股沟疼痛中常见的磁共振成像发现。然而，即使是无症状的运动员也存在 PBME，并提出了与体力活动或更高血流量的相关性。关于耻骨联合血管解剖的数据很少。

方法

解剖了十具经甲醛防腐处理的尸体，并对动脉血供进行了调查和照相记录。

结果

在大多数情况下，确定了以下模式：上 腹下动脉（n = 12 个半腹股动脉）、阴茎背下动脉/阴蒂背动脉（n  = 16）、闭孔后动脉（n  = 16）半骨），前深部阴部外动脉（n  = 14 半骨）。除了前部深部外阴动脉的变化外，我们还观察到高度可变的动脉供应，尤其是优越的。发现 4/10 尸体上位，0/10 具下位，2/10 具后位，5/10 具前位。

结论

耻骨联合具有空间丰富且组织丰富的动脉血供，有多种变化。尽管耻骨联合被认为是肌萎缩，但在压力情况下，例如在高强度训练中，可能需要大量的血管。
