Repairs of surgically produced wounds require fore-thoughts and planning individualized for particular patients and particular original conditions. Nowhere is this more important than in patients treated by Mohs' methods for cutaneous cancers. Indications for early and late repair and methodology by a variety of grafts and flaps are explored and illustrated.

Segments 15 mm in length were excised from the femoral veins of rats and preserved by refrigeration at 4 C in lactated Ringer's solution for periods up to 21 days. The findings show that veins can be preserved for up to seven days and successfully grafted to recipients. Although there was some success in preserving vein segments for more than seven days, a high rate of thrombosis occurred after implantation in the recipients. It is generally accepted that damaged endothelium causes thrombosis. The light and electron microscopic observations in this study, however, suggest that the condition of the endothelium may not be the only important factor in the patency of small vessels. A thickened and prominent elastic lamina may also play a role in keeping the lumen open
