Figure 1. Midsagittal section of pelvis showing the branches of IIA. The arrows point to the two uterine arteries supplying the uterus: UA, AUA, CIA, EIA, PD, AD, PS, UB, VA, IPA, LST, S1, S2 and S3 nerves. IIA: internal iliac artery; UA: uterine artery; AUA: aberrant uterine artery; CIA: common iliac artery; EIA: external iliac artery; PD: posterior division of IIA; AD: anterior division of IIA; PS: pubic symphysis; UB: urinary bladder; VA: vaginal artery; IPA: internal pudendal artery; LST: lumbosacral trunk; S1: ventral rami of first sacral; S2: second sacral; S3: third sacral nerves.
Figure 2. Midsagittal section of the pelvis showing the IGA arising from the PD, SGA, IIA, CIA, EIA, PS, UB. The arrows point to the two uterine arteries supplying the uterus: UA, AUA. VA, IPA, LST, S1, S2 and S3 nerves. IGA: inferior gluteal artery; PD: posterior division of the IIA; SGA: superior gluteal artery; IIA: internal iliac artery; CIA common iliac artery; EIA: external iliac artery; PS: pubic symphysis; UB: urinary bladder; UA: uterine artery; AUA: aberrant uterine artery; VA: vaginal artery; IPA: internal pudendal artery; LST: lumbosacral trunk; S1: ventral ramus of first sacral nerve; S2: ventral ramus of second sacral nerve; S3: ventral ramus of third sacral nerve.
Figure 3. Midsagittal section of right pelvis from a donor showing normal UA for comparison. CIA, EIA, IIA, PD, AD, SGA, IGA, IPA, PS, UB, L5, S1. CIA: common iliac artery; EIA: external iliac artery; IIA: internal iliac artery; PD: posterior division of IIA; AD: anterior division of IIA; SGA: superior gluteal artery; IGA: inferior gluteal artery; IPA: internal pudendal artery; PS: pubic symphysis; UB: urinary bladder; L5: fifth lumbar vertebra; S1: first piece of sacrum.
