Secondary arterial repair after aortoiliac surgery

Late complications after operations on aorta and iliac arteries are analyzed in 763 patients with athesclerosis over 15-year period. Indications for recurrent reconstructive operations are presented, and the results of these operations are analyzed depending on surgical technique, incidence of recurrent thromboses and types of complications. Angiography, rheovasography, pathohistological and microscopic studies, raster electron microscopy, IR-spectroscopy were used in post-operative period. On the basis of the obtained data the following conclusions have been drawn. For more than a quarter of patients operated for aorto-iliac occlusions it was necessary to perform recurrent reconstructive operations in late post-operative period. The incidence of recurrent operations depends on many factors: stage of ischemia, nature of atherosclerotic lesions, technique of reconstruction. In primary operations profundoplasty was performed in comparatively rare cases.
