- Objective - to evaluate blood supply of flap covers in the remote period after flap coverage of wounds in hand defects. Material and methods. Cutaneous bloodflow was examined in the remote period (in 5.4 years) after flap coverage of wounds in hand defects in 8 patients by triplex scanning (9 flaps, among them 6 persons with axial source of bloodflow and 3 ones with segmental source of bloodflow). Results. In 83% cases in the flaps with axial source of bloodflow the axial bloodflow maintenance was marked and its mean rate was amounting to 15.2 ± 7.8 cm/sec; the distinctions concerning healthy tissues did not reach statistical significance level. Mean rate of direct collateral bloodflow was amounting to 11 ± 14.9 cm/sec (12.2 ± 13.7 cm/sec in healthy tissues, p < 0.05). In the flaps of segmental type the mean rate of direct collateral bloodflow was significantly higher than in healthy tissues (16.8 ± 11.2 and 10.4 ± 9.6 cm/sec respectively, p < 0.05). Conclusions. Flaps with axial source of bloodflow were better adapted to healthy tissues; complete axial (83%) and collateral bloodflow were maintained in them; their bloodflow rate did not differ from the bloodflow rate in surrounding tissues. Blood circulation with segmental type of bloodflow in the remote period was realized owing to collateral bloodflow acceleration.
