Abstract:
Objective To provide anatomical basis for the free saphenous branch of descending genicular artery flap and evaluate its clinical outcomes for the hand soft-tissue defects. Methods Fifteen fresh cadavers injected with lead oxide-gelatin mixture for three-dimensional visualization reconstruction using a spiral computed tomography scanner. The origin, course and distribution of the perforators of descending genicular artery were observed.From January 2005 to October 2011,seven patients with skin defect on the distant limbs were treated.The flap size was 5 cm × 6 cm-11 cm × 14 cm,vascular pedicle length 5.4 (4-7)cm. ResultsThe saphenous branch was consistent. It arised from the descending genicular artery (68％) or femoral artery(32％).The diameter of the saphenous branch was 1.5(1.1-1.7)mm at its origin above 9.0(4.0-16.0)cm from the medial epicondylar.Seven cases of flaps all survived,the average followup of 28 months,close to hand flap of skin texture,some sensory recovery,two-point discrimination 8-12mm. Conclusion Free saphenous branch of descending genicular artery flap is a reliable option for the treatment of soft tissue defect in hands. The pedicles were invariable of anatomy, thickness of the flaps is comparable,and procedure is simple and time saving.
