Microarteriorrhaphy: blood flow after wound healing.
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 greater than .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.

Interrupted and continuous microarteriorrhaphy techniques: a hemodynamic comparison.
The purpose of this study was to compare interrupted and continuous suturing techniques in laboratory microarteriorrhaphy. The comparison was based on rat femoral artery hemodynamic variables, including blood velocities, lumen diameters, and calculated blood flow. These variables were calculated by an offline computer from Doppler frequency shifts that were measured by a 20-MHz pulsed ultrasonic Doppler velocity meter. No statistical difference was noted postoperatively between the interrupted and continuous techniques relative to any hemodynamic variable. Average blood flow after the interrupted (n = 12) and continuous (n = 12) techniques was 6.59 +/- 1.12 and 6.74 +/- 1.20 ml/min, respectively. The two microarteriorrhaphy techniques result in equal postoperative vessel hemodynamics in a laboratory model.
