Abstract
We describe our experience with plaque excision and placement of a venous patch graft. Sprague Dawley rats (n = 20) underwent excision of a wedge of tunica albuginea with the defect covered by a segment of detubularized femoral vein, endothelial side towards the cavernous tissue. Erectile function, as determined by the rise in intracavernous pressure with cavernous nerve stimulation (mean 54.0 ± 4.2 cm. H20), was equal to that in a group of 10 intact age-matched controls (mean 46.9 ± 3.37 cm. H20). Penile cross-sections stained with Hart’s elastic fiber stain or Trichrome stain revealed only minimal fibrosis in the region of the patch.
