Is. Johnsrude et al., POSTLAMINECTOMY ARTERIOVENOUS-FISTULA MASKED BY STENOSIS OF THE INFERIOR VENA-CAVA, Cardiovascular and interventional radiology, 17(6), 1994, pp. 336-338
Discovery of a postlumbosacral discectomy fistula between the right il
iac artery and vein was obscured by an associated severe stricture of
the infrarenal inferior vena cava in a 49-year-old man. During venous
stenting for treatment of peripheral edema, the fistula was suspected
because of faint pulsatile right iliac vein flow and increased O2 satu
ration of the venous blood. The suspicion was confirmed on subsequent
iliac arteriography. Surgical closure of the fistula with arterial int
erposition grafting was then performed. The patient improved substanti
ally.
