BILATERAL PERSISTENT SCIATIC ARTERIES (PSA) AND VARICOSE VEINS: MRI DEMONSTRATION OF AN UNUSUAL ASSOCIATION
Journal Title: GJRA-Global Journal For Research Analysis - Year 2018, Vol 7, Issue 1
Abstract
Persistent sciatic artery (PSA) is an extremely rare anatomical variant of lower limb arterial supply with an incidence of 0.025-0.6 % as estimated on angiographic studies. This vessel is prone for atherosclerosis, aneurysm formation and rupture, sciatic neuropathy, and ischemia of the lower extremities. It is important to diagnose this condition pre operatively especially in renal transplant surgery and in surgeries around the hip joint as trauma to this anomalous vessel can have disastrous consequences. It is associated with other congenital anomalies including Mullerian and left renal agenesis, A-V fistula formation, hypertrophy or hypotrophy, multiple hemangiomata, neurofibromatosis, or anomalies of leg arteries. Association of this anatomical variant with varicose veins is very rare and rarely discussed in literature. We report the youngest patient till date with this unusual association demonstrated on MRI.
