Abstract
The present study tests the hypothesis that early wound healing effects blood flow after experimental microarteriorrhaphy. Hemodynamic variables were measured in the rat femoral artery prior to and 3 weeks after both interrupted and continuous microarteriorrhaphy techniques. The hemodynamic variables (blood velocities, lumen geometry, and calculated blood flow) were measured by 20‐MHz pulsed ultrasonic Doppler velocity meter (PUDVM) methods. The control values (N = 22) and the 3 weeks postoperative values, for both the interrupted (N = 11) and continuous groups (N = 11), were not statistically different (P > .01). The average calculated blood flows were as follows: control group 10.85 ± 1.45 cc/min, interrupted group 12.01 ± .92 cc/min, and continuous group 8.50 ± 1.45 cc/min. Three weeks of wound healing after microarteriorrhaphy did not significantly change blood flow variables compared to preoperative values.
