title: Tissue expansion and cutaneous blood flow.
abstract: The effect of controlled skin expansion in blood flow was investigated using the dermofluorometer. Twenty-eight subcutaneous pockets in seven pigs were divided into three groups. Group 1: subcutaneous pockets with a gradually inflated 200-cc tissue expander over 12 days, then deflated and observed for 6 days. Group 2: subcutaneous pockets with a noninflated 200-cc tissue expander. Group 3: subcutaneous pockets elevated without placement of a tissue expander. Measurements taken 30 to 45 minutes after partial inflation of the tissue expander showed a decrease in blood flow while blood flow was increased 30 to 45 minutes after deflation of the tissue expander. The increase in blood flow, however, was not evident 6 days after the expander in group 1 was deflated.
