The collateral arterial circulation in the pelvis. An angiographic study.

Abstract

Nineteen patients ranging in age from 9 to 49 years were subjected to pelvic angiography following internal or common iliac artery occlusion. None of those patients manifested evidence of cardiovascular disease.Roentgenographic demonstration of the major arterial anastomoses is presented. The anastomoses shown are:1. Last lumbar→iliolumbar2. Lateral sacral↔lateral sacral3. Middle sacral→lateral sacral4. Superior hemorrhoidal→middle hemorrhoidal5. Medial femoral circumflex→inferior gluteal6. Medial femoral circumflex↔obturator7. Lateral femoral circumflex→superior gluteal8. Deep iliac circumflex→superior gluteal9. Deep iliac circumflex→external iliac10. Last lumbar→superior gluteal11. Last lumbar→deep iliac circumflex12. Iliolumbar→deep iliac circumflex.These anastomoses have been shown to function immediately following occlusion.Attempts at reduction of blood flow to pelvic structures may be successful, although complete cessation of perfusion probably cannot be accomplished.Occlusion of the external ilia...
