Ureteral obstruction secondary to bifurcated aortic grafts
J. G. Antkowiak and R. A. D'Altorio
We report three cases of ureteral obstruction producing hydronephrosis
following aortofemoral bypass graft. In each case, the obstruction occurred
in the area where in the ureter crossed over the limb of a Dacron graft.
Ureterolysis relieved the obstruction. Most of the previously reported
cases of this complication of bypass surgery occurred when the ureter was
situated between the limb of a graft and the patient's own iliac artery.
Various methods of surgical appraoch are listed. In some cases,
ureterolysis is a suitable alternative to division and reanastomosis of the
ureter to relieve obstruction.
