Persistent sciatic artery and sciatic artery aneurysm: a hazard in hip surgery.
During a posterior approach to the hip joint great caution must be exercised in protecting a persistent sciatic artery. Inappropriate trauma could either cause peripheral embolization, propagation of mural clots, or rupture. Prior to ligation, arteriography is critical because, despite the presence of strong femoral or popliteal pulses, the persistent sciatic artery may be the main conduit to the lower extremity.
