Abstract:
Objective To compare the clinical effects of of arterialized venous flap (AVF) with different perfusion strategies for repairing hand soft tissue defects. Methods Ninety-six patients with hand soft tissue defects from January 2015 to June 2018 in Gaozhou Traditional Chinese Medical Hospital were collected and randomly divided into two groups: the inverted group (48 patients) treated with anti-valve arterialized venous flap inverted anastomosis and the non-inverted group (48 patients) receiving pro-valve arterialized venous flap non-inverted anastomosis. The excellent and good rate of hand function recovery, flap survival rate,postoperative skin flap response degree and treatment satisfaction between two groups were compared. Results Compared with the inverted group, the flap survival rate in the non-inverted group increased significantly [97.9% (47/48) vs. 83.3% (40/48)], the proportion of mild flap response degree increased [45.8% (22/48) vs. 18.8% (9/48)], the proportion of severe flap response degree decreased significantly [12.5%(6/48) vs. 41.7%(20/48)], and the differences were statistically significant (χ2＝4.391, 7.032, 8.205, P < 0.05). The excellent and good rate of hand function recovery in inverted group and non-inverted group had no significant differences (χ2＝1.233, P＞0.05). There was no significant difference in satisfaction with the shape of skin flaps, finger function and donor site recovery between two groups(P＞0.05). Conclusions Compared with anti-valve arterialized venous flap inverted anastomosis, pro-valve arterialized venous flap non-inverted anastomosis on soft tissue defect repairment of hand can efficiently increase the survival rate of flap and improve the flap response degree after operation.
