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

BACKGROUND
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
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
CONCLUSIONS
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.
