Types of inferior phrenic arteries: a new point of view based on a cadaveric study.

Our findings suggest the presence of six different types of LIPA and RIPA origin. The most common form is type 1, characterised by an IPA originating from the abdominal aorta, while the second most common is type 2, in which the IPA originates from the AA by a common trunk. The diversity of other types of origin is associated with the occurrence of coeliac trunk variation (type 3). No significant differences in RIPA diameter could be found, whereas LIPA diameter could vary significantly. No significant differences in RIPA and the LIPA diameter could be found according to sex.
