The origin of profunda femoris artery in Thais.

ABSTRACT

This study was to investigate the variation patterns of the origin of profunda femoris artery (PFA) in terms of normal and variation patterns in human preserved cadavers. Two hundred and twenty four femoral triangles in human preserved cadavers were dissected. Sites of origins were identified. Diameter and distance of PFA were measured. We found that PFA was mostly originated from posterior site of femoral artery (FA) at a distance of 35 mm from midpoint of inguinal ligament. Compared between sexes and sides, these distances in females (31.54 mm) approved more proximally than those of males (37.68 mm) at p=0.017. Moreover, the distances on the left sides (33 mm) approved more proximally than the right sides (36.22 mm) at p=0.006. The average diameters of PFA were 5 mm, females (5 mm) were smaller than males (5.42 mm) with p=0.017. In conclusion, PFA that we found was originated from posterior site of FA and average distance of its origin was about 35 mm. Regarding undertaking operative or interventional procedures within the femoral region, this knowledge could be applied to prevent complication during surgical approach or percutaneous vascular access.
